A to B 36 Blog, June 2003, Bike Show

FIRST PUBLISHED June 2003: Bike Show, Round*Up 2003

In April the Mole braved one of Virgin’s new ‘compact’ Crosscountry trains to visit the Bike Show at Birmingham’s ‘International’ Exhibition Centre. According to the positive spin from Cycling Plus magazine, this formerly youth-orientated shindig was to be transformed into a mainstream (ie, CYCLE-style) show for 2003 and was thus worth a visit by those over 20. Approaching the hall with a crowd of sub-12 year old boys, one began to suspect that the hype might have got slightly ahead of the actualité.

For any elderly folk who might – reasonably enough – be drawn by the ‘Bike Show’ title in future years, the Mole can confirm that the event consists largely of noisy BMX displays, with a side order of mountain-style machines for the twenty-plus old-timers. In other words, it’s a dead waste of fifteen quid.

Leisure cycling is big business in the UK. According to the current What Mountain Bike? advertising rate card, the print run for this single title now exceeds 50,000, and the overwhelmingly male readership (94%), has an average age of 32, and annual income of £22,905.

A to B magazine, Bike Show, Ebryo ScooterAt the Bike Show, a selection of nefarious stall-holders were hard at work pocketing wads of cash from young men of this kind. One such outfit was Ebryo Scooters, purveyor of a monstrous electric scooter known in its country of origin as the Flying Dragon, but repackaged as the ‘Street Runner’ for the UK where dragons have less relevance in marketing terms.

The Mole took great delight – as one does when the opportunity arises – in informing the sales girls that this £500 machine (show special £400) was illegal on streets, pavements, cycle paths, or indeed, anywhere other than private land. And a little market research might have revealed this, saving a great deal of embarrassment.

Elsewhere, the Comfort Saddle company was busily steering bottoms onto its product.This ludicrous device looks rather like a leatherette bench seat, of the kind that made a brief appearance in early 1950s motor cars. Gentlemen of a certain age may recall that these softly-sprung wonders provided an unrivalled means of getting intimate with one’s passengers, but gave little in the way of support, should one not wish to slide rapidly across the car. This characteristic is all the more pronounced on a bicycle, where such and annual income of £22,905. At the Bike Show, a selection of subtleties as road positioning and hand gestures are accomplished – without putting too fine a point on it – by gripping the saddle with one’s nether regions.The Comfort is further hampered by a strange spring device that allows the saddle to flex, yaw and roll to angles that bottoms are rarely taken.

When the Mole expresses some mild scepticism, the Comfort apparatchiks claim that the saddle has been widely tested both on and off road, with no apparent tendency for riders to slip from their steeds.Thus, should any readers with flat non-slip bottoms wish to lighten their wallets to the tune of £39.95 plus postage, the means is now available.

Growing weary of bicycling in England, the Mole trekked 3,000 miles in search of enlightenment to Trophy Bike’s Round*Up 2003 folding bike show in Philadelphia, USA.

For those unfamiliar with foreign parts, America is very large, with many busy freeways and a considerable volume of traffic, all going the wrong way. Arriving a little late in the evening at Newark’s rather depressing airport (not unlike landing in a scrapyard), one rapidly establishes base camp at the North Elizabeth Econolodge, pausing only to look right rather than left whilst crossing the adjacent highway, which causes much cheerful honking from home-bound commuters. Incidentally, the Econolodge offers complimentary ‘donuts’ and coffee in place of breakfast, and a half-hourly courtesy coach from the airport, for those lacking the nerve to tackle US highway one by bicycle.

With bicycles now something of a novelty in the United States, a folding bicycle is akin to the sort of novelty that might fall from a McDonald’s Happy Meal.

Folding bicycles are not yet part of the American Dream, although the day of enlightenment might come, just as soon as the population is able to work out what they are for.Thus, the visitor tally at the Round*Up show proves something of a disappointment, particularly as many of the visitors turn out, on closer inspection, to be A to B readers, rather than folding newbies.

A to B magazine, Round*Up 2003Without exception, the select band of US A to B readers (literally one in million on the statistical evidence) prove to be a delightfully charming and urbane bunch. This is fortunate, for at Round*Up they find themselves face to face with a group of equally pleasant, but distinctly potty foreigners, who mostly appear to be intent on selling them folding bicycle trailers.

At around lunchtime on Day One, we make a soggy procession up Market Street, pausing only to retrieve bits of folding trailer sucked into the paths of taxicabs by the fearsome jetstreams of rain.

US mayors are made of strong stuff, but the Philadelphian incumbent takes refuge amongst his aides as our strange caravan files into a marquee on the steps of City Hall. There follow a number of the usual speeches – grateful thanks, shame about the weather, new era in transportation, etc – during which it slowly dawns that this is Philadelphia’s primary Bike to Work Week event, and our small group of potty foreigners is the primary exhibit. “…this is the primary Bike to Work event… and our small group of potty foreigners is the primary exhibit

Of local bicyclists we see none, although a number of advocacy groups have turned out, and they are all busily advocating this and that to the potty foreigners, who are trying to sell them trailers. Meanwhile, at the other end of the tent, the official stuffed shirts are calling for tolerance, in grim tones.

It appears that bicycle/auto relations have plumbed new lows in the city, although one doubts whether the average citizen would be able to recall the last time they saw a bicycle, let alone engaged in kerbside argy-bargy.

A number of bemused TV crews dutifully film the folding bikes folding and unfolding, and the trailers doing whatever it is that folding trailers do, before the mayor paints a small section of the rather optimistically-inclined bicycle mural, then legs it back to City Hall, leaving the foreign bicyclists to trudge gloomily out into the rain.

‘Wandering’ Hanz Scholtz and Lynette Chiang of Bike Friday

mayor-philadelphia

The mayor of Philadelphia works on the cycling mural

Days Two and Three prove equally entertaining, with talks from Bike Friday’s roving ambassador ‘Wandering’ Hanz Scholtz  and marketing sidekick Lynette Chiang,  who will need no introduction to long- term A to B readers.The following day,  Airframe designer Grahame Herbert arrives, accompanied by his delightfully unflappable wife Lorraine.The pair have ridden for several hundred miles up the coast – a great success as proving runs go, but rather spoilt by unfavourable road conditions.

Cycling in the USA varies, just as it does in overcrowded Britain, although minor roads are generally quieter and less frenetic, if you can find them. Bulky Sports Utility Vehicles are more common of course, as are stretched limousines and other More colour images at oddities.The latest cult urban attack vehicle is the military Humvee, and its almost unimaginably daft cousin, the stretched Humvee. Yes, for a trifling sum, you can hire one of these monsters and terrify your friends. Or join the mercenary business. Stretched Humvees make an entertaining sight, provided you don’t intend to cross the road.

Urban coup d’état chic is nothing new, but where Brits cheerfully make do with a pair of battle fatigues and an artfully arranged scarf, the Yanks go in for more serious hardware. Love it or hate it, there’s a certain style there.

As US vehicles grow ever larger, so do their occupants. This appears to be an uneven process, for the majority (including 100% of A to B subscribers, naturally) are pleasantly, or at least reasonably slim, but some 20% of the population is now reckoned to be clinically obese, against a piffling 12% in 1991. In a recent US government survey, 27% of recipients admitted that they ‘did not engage in any physical activity’, beyond (one assumes) keeping blood flowing around their vital organs. At the risk of being terribly obvious, perhaps the US should rediscover the bicycle in a hurry?

SS United StatesShould one have time to kill in Philadelphia, the SS United States is well worth a visit. Built in the 1950s, just a decade before the horrors of air travel destroyed the elegant liner trade, the vessel is a rare survivor.Withdrawn from the Southampton to New York run in 1969, she changed hands a number of times, circling the world from shipyard to scrapyard and back, as each project foundered. Finally, stripped to the bones internally, the great liner came home and has been moored on Philadelphia’s Delaware River ever since, awaiting restoration… or the scrapyard. One hopes that one of the various projects will eventually succeed.

…the yanks go in for serious hardware. Love it or hate it, there’s a certain style there…

For liner-geeks, the United States had turbines of 240,000 horse power, offering an unmatched power to weight ratio, and a top speed of 43 knots, or 50mph. She was, however, a tiny bit shorter than the France (now, rather confusingly, called the Norway), or our own dear Queen Mary or Queen Elizabeth, but we shall not dwell on such trifles.

Would today’s jaded air travellers be willing to swap jet lag and deep vein thrombosis for more relaxed travel, one wonders? The market for cruise liners is growing rapidly, but it’s hard to imagine today’s business traveller swapping a six-hour flight for three or more days at sea. Perhaps the liners could be marketed as enforced health camps, offering their captives three days of unrelenting pain in exchange for a few glasses of carrot juice.

cycling-scotlandBut enough of what might be, for we must journey to Scotland, which is visibly pulling clear of our increasingly dis-United Kingdom in transport terms.The latest innovation from north of the Border is a pro-cycling advertisement:Thirty seconds long, the film makes a mockery of those annoying car ads where square-jawed young fellows get the crumpet by driving much too fast on remarkably empty roads. In this memorable example, our hero takes to commuting by bicycle, arriving faster and very obviously getting the crumpet in the shape of a pair – no less – of voluptuous cycle courierettes. Cycle commuting has been on the rise for some years in urban Scotland – up 38% in Glasgow and 65% in Edinburgh during the 1991-2001 census period. Just watch it accelerate now.

It’s hard to imagine anti-car advertisements in a totalitarian state such as England, of course. But in those provincial pockets where the grateful citizenry has cast off the New Labour yoke – London, for example – things are going a little better: A combination of central zone Congestion Charging and widely distributed cycle maps has increased cycle use in central London by 16% in a matter of weeks. Mayor Livingstone, bless his heart, is now enthusiastically pushing for the Charge zone to be extended westwards, with 20mph limits on most residential streets.

Yet even in the capital, research by Transport for London has found that 38% of non- cyclists are ‘worried that friends will laugh at them’ should they try cycling. A case for TV advertising, surely?

But we shouldn’t believe everything the authorities tell us. Readers may recall the graph in A to B 30 drawn from Department for Transport statistics, showing cycle use plummeting by more than 10% in seven years. Following a mysterious hiatus, the figures have been reissued as a 10% rise in the same period.Well, fancy that! But wait…. in the same bulletin, provisional results for early 2003 are indicating a renewed and even more catastrophic fall of 11%. Sometimes you just wish Tony would make up his mind!

Useless Cycle Network

The picture on page 41 of A to B 35 sums up the situation in Nottingham (and too many other British cities) as far as cycling ‘facilities’ are concerned – white lines painted along uneven pavements obstructed by signs, traffic lights, trees etc. If this is British best practice, I’d rather not have it, thanks! The best lanes in Nottingham are the bus lanes – they are wide, clear, smooth and regularly swept of debris. And they’re in force 24 hours a day. The biggest problem with cycling in Nottingham is the ring road and horrendous one way system, which seems always to prevent you from getting where you want to go, to such an extent that ignoring ‘No entry’ and ‘No right turn’ signs will often get you to your destination quicker and more safely than going round Broadmarsh several times.

Oh, and for an example of the differing attitudes of road builders to cyclists and motorists, one only has to look at Raynesway (A5111) in Derby, which has just been slewed (to make way for yet another bypass).The road surface is excellent, but the token cycle path alongside seems to have been shovelled out of the back of a lorry and then stamped down with a pair of welly boots. Needless to say, I use the road!

Please Sell me a Ticket!

I’m riding the Paris-Brest-Paris Audax ride in August on my old Moulton and I want to take the train there and back with my bagged bike. I’d prefer to travel there 16th August and return 23rd August.

I’ve previously read in A to B that I should be able to get through tickets (possibly discounted) from my Midlands station (Tamworth) to Paris rather than a ticket to London, plus Eurostar ticket, but I can’t find a method that works.When I try to book online on the Virgin or other British railway websites, nothing recognises Paris, Gare du Nord or similar. Any suggestions as to how I can get through ticketing from Tamworth to Paris (ultimately St Quentin-en-Yvelines, but Gare du Nord would do)?

Dave Minter
Via email

The failure to establish a user-friendly through ticket system has to be one of the biggest scandals of the rail privatisation debacle. Although long-distance trains stop at Tamworth, the station is run by Central Trains, and in your area only Virgin sells through tickets, so you’ll have to buy separate single tickets to and from a Virgin station.Then,Virgin can only sell tickets to Eurostar destinations, so you’ll need separate local French tickets too.That said, at £79 to £89, the Birmingham – Paris bit can be good value.The Virgin customer service line is 0870 789 1234. For train times, German Railways (www.bahn.de) provide an excellent English-language European service, but you’ll still have three tickets to book. Any better suggestions? (Eds)

Sturmey Responds

Just a couple of points about your report on the Dahon Vitesse (A to B 35).The Sturmey- Archer 3-speed is not the same as when it came from Nottingham, as the hub internals are very different.With the original AW hub, it was possible to find a ‘false neutral’ between gears 2 and 3, which nobody really minded until Dutch manufacturers asked us to correct it 15 years ago.We consequently introduced a ‘no in-between gear’ (NIG) 3-speed hub in 1989, but only in the drum-brake version, which is widely used here in the Netherlands.The old AW 3-speed continued to be made alongside the new hub, largely because it was a cheaper system.

When production was moved to Taiwan, the new owner was naturally unwilling to produce two different 3-speed systems, so the NIG was introduced into the AW. Spares for the AW will eventually run out, but the internals of the new hub (part number HSX143) were designed to fit the old hub shell.The gear indicator toggle chain is also longer.

Note too, that when Sunrace bought Sturmey-Archer they quickly recognised that the Sturmey-Archer name was much stronger in Europe than elsewhere, so the decision was taken to omit the Sunrace name and continue to brand the products as Sturmey-Archer.

Nothing New

As an older reader (just celebrated my 80th birthday) and Pashley Moulton ATB rider, can I join in the debates? First,The Mole’s mention of Milton Keynes in A to B 35: I seem to remember the place was first conceived, with its grid-iron layout, as being dedicated to public transport (trams!) and cycleways, before the motor lobby hijacked the town.

Next, your News (page 19, A to B 35) that they’ve re-invented the shaft-drive. And why not? I’ve heard of shaft-drive bikes in the 1920s and ‘30s: it was only the slump in that decade which killed them off. I also recall the Trident (unfortunate name) from the 1980s, which had lovely German-designed skew gears in the rear wheel stay, but was ruined by a rubbish frame from Taiwan.Then there was a good made-in-Germany roadster, not to mention my old Yamaha Townmate scooter and other motorbikes, from the beautiful 1950s Sunbeam to BMWs. Shaft-drive must have a future, especially in transport bikes, and it’s a perfect match for the indispensable hub gear.

Doc Arnold
Appledore, Devon

Interesting about Milton Keynes: we’d never heard that before, but it might help to explain why this very car-centric town has a street pattern focussed on the railway station… According to Carlton Reid of cycle trade magazine BikeBiz, the Sussex drive unit fitted to the Aurora bikes may be the same unit that was fitted to the Trident back in the 1980s – apparently it first made an appearance at about that time. (Eds)

Which Airport Folder?

We require folding bicycles in a case of suitable dimensions to take on package tours.The cases must be able to withstand the rigours of airport handling and protect the bikes. The machines are for touring day rides of up to 50 miles – they must have mudguards, a gear ratio from below 40 inches to 75 inches, and carry the food, tools and clothing required on the ride. Is anything produced that meets our requirements? If not, would you suggest a compromise?

Richard & Margaret Nicholl
Wincanton, Somerset

We generally recommend the Bike Friday or the Brompton for hard case carriage by air, because these two fold into particularly square, compact, packages – the best defence against airline baggage handlers. If you like the Brompton’s rather upright stance, the L6 offers a gear range of 40″ – 86″ (or a bigger range with aftermarket sprockets), weighs from 11.6kg and costs £524. Fit a decent saddle and bar-ends, and this bike is more than capable of holding its own with sportier machines. If you do a lot of this kind of thing, a Bike Friday makes sense – typically expect gears of at least 31″ – 90″, weight of 10kg and price in the £1,000+ region.We should also mention the Airframe (light, but a bit bulky), the Birdy (full suspension, but equally large) and assorted Dahons (cheaper, but mostly larger and heavier). (Eds)

Tried the BMW?

We live near Rochester, upstate New York, and ride around the parks and along the Erie canal with two children, one on a tag-along behind my wife’s Birdy, while I ride an Airnimal. I can thoroughly recommend this fast, light and sturdy bike. I have a fast set of wheels (Araya rims fitted with 28 spokes) and an ‘all purpose’ set with standard rims and Spanky knobbly tyres.The climate here does not help – we are very near the Canadian border and there is lots of snow for five months of the year. So even with the knobbly tyres, it seems that I may have to invest in a more conventional mountain bike. I wondered if you considered reviewing the BMW folding mountain bikes (Q3.S and Q6.S) or if any of your readers have any recommendations? They certainly look like mean machines, but with a serious price tag (just under $1000 and $4000 respectively).

Baz van Cranenburgh
Fairport, NY, USA

For many years BMW folding bikes were thinly disguised Montagues, but the Q3.S and Q6.S are very different.We’ve been unable to get a bike from BMW, or a reply from Montague, but we notice that BMW is still listed as a partner on the Montague website. Anyone know more? (Eds)

The Holy Grail

I continue to search for an electrically-assisted bike which will give me enough help on our steep hills here in the Chilterns.Through the kind assistance of Addiktion Cycles in St Albans, I had a good long trial ride round the outskirts of the town on a new Lafree Twist. It was exhilarating on the flat, down hill and up slight hills, but it did not give me enough help on significant hills. Admittedly, I am nearly 73 years old, out of condition and on blood pressure drugs, but I am still disappointed, because you found it ‘possibly the best power- assisted bike, so far’.

I have tried other bikes in the past, but ruled them all out (Powabyke too heavy, Heinzmann too expensive, etc). Do you have any other suggestions, please? I really enjoyed my ride today, except for the steeper hills!

We were impressed by the Ezee Forza (see page 34), or try the Electro-Drive kit, which has limited range, but will climb almost anything:Two contacts – tel: 07974 723996 or 01244 671999, or email: sales@electro-drive.co.uk or sales@pedalandpower.co.uk

Cheaper at Halfords

The article about map holders in A to B 34 was of particular interest as I have been using the Zefal map holder with my Brompton for over five years, but mine came from Halfords and cost £3.99. It appears to be just the same as the Zefal and is available in all Halfords branches under their own cycle luggage label, although it now costs £4.99.

I am thinking about getting a carrying case for my Brompton as it is getting more use on public transport these days.The case made by Carradice appeared to be a nice piece of work when I examined one at the London CYCLE show last year, but they’re expensive and produce a rather bulky package to carry around when riding. However I see that Dahon markets a bag for folding bikes with 16″ wheels which they claim will fit the Brompton. It is made from tough padded nylon with shoulder straps, and when not in use the bag folds into its own pocket and can be carried as a waist pack.This ‘Doubleplay’ bag looks ideal, and costs only £24.99.The problem is that none of my local dealers had heard of it.

Dahon tell us the Doubleplay is out of stock, but the standard 16-inch bag is available direct for £19.99, plus £3.50 postage.Tel: 01580 890007. (Eds)

Golden Days Awheel

I had subscribed to A to B for nearly three years off and on before I purchased a Brompton L6 last August.Thanks to your readers’ letters I was able to ask all the appropriate questions, and was pleased to see that the nice copper-haired Stephen at Ratcliffes of Leigh gave honest replies, didn’t dismiss my concerns, and didn’t treat me like a mithering pensioner. Nor did he bat an eyelid when I returned from a 40-minute trip around the town

.

The Brompton has exceeded all hopes and met all my needs so far. I find the saddle unsuitable for a day ride, but I’m reluctant to change it because I’m reluctant to increase the weight, which I find just manageable.

It was the sheer joy of reading Albert Winstanley in Cycling World that first got me on a bike in my early forties. I hope he’s still around – please write another letter Albert! Perhaps you could reveal the whereabouts of any hidden copies of Golden Days Awheel – a cycling treasure discovered in the St Helens Central Library?

Albert still resides at a very earthly address in Bolton, Lancashire. (Eds)

Brompton Update

A few comments on my Brompton, which is used for coastal surveying work:

1) Schwalbe Marathon tyres: No punctures in 3,000km (1,900 miles) of use – part urban commuting where the problem is broken glass, and survey work where most punctures are due to thorns.The rear tyre lasted 3,000km, but the front has not been changed.

2) Pedals:The folding pedal got a bit too worn after about 2,000km (1,250 miles), so I have fitted old track pedals with toe-clips. I carry a 15mm spanner should I need to remove the left-hand pedal. I intend trying the MKS removable pedals when these become available.

3) Saddle height adjustment: Being tall, I fitted a telescopic seat post, and when folding the bike, I sometimes remove the top section.When unfolding, the main stem comes up to the maximum, and the top section is fitted with a plastic collar which also secures a rear LED. Removing the saddle helps with train racks, but is not usually necessary.

4) Rear frame pivot:This has worn a lot, probably due to salt, sand and water getting in during survey work, so the frame will be going back to the factory soon for new bushes. I intend to fit a grease nipple to improve bearing life.

5) Carrying bag: I made a nylon bag to carry the Brompton, with pockets for the saddle and left-hand pedal.This is useful on ferries that charge for bikes and in some (posher) hotels.

Solar Powered Transport

Professor Pivot“I’ve always been interested in the idea of solar-powered transport, but no-one seems to have built anything practical yet. Is a solar vehicle a practical proposition in the UK?”

Jonathon Crouch
King’s Lynn

Professor Pivot replies:

Clean inexhaustible solar power has been a transport dream since photovoltaic cells first began converting light directly into electricity, but the reality seems as far away as ever. Solar cells have many applications these days, from lighting remote telephone boxes to powering satellites, but for transport, the problems are two-fold: cost and energy efficiency. At £5 to £20 per watt (bigger panels are much cheaper), the cost has changed little for some years: It’s the classic Catch 22 of high technology produced in low volumes, but increased demand for other high technology products has seen prices tumble, so the same is bound to happen to photovoltaics eventually.

Energy efficiency is a more taxing problem. Photovoltaics are improving rapidly, but most convert only 10 to 15% of the light energy hitting their surface into electrical power. Specialist cells of 25% efficiency are becoming available, and 35% or more is possible in the laboratory, but to avoid disappointment, we should work on a performance of a little over 10%.

Solar Cars?

Cover the horizontal panels of a typical car in photovoltaics, and you might cram in six square metres, trapping around 3 kilowatts of energy, but giving a peak output of only 0.4 kilowatts of electricity.To reproduce internal combustion performance, you’d need 30 kilowatts or so.Thus, with today’s technology, under ideal summer conditions, we could expect to generate around 1% of the peak power required. In practice, cars spend far more time sitting in the sun than moving, but even with the best panels charging a battery all day long, range would be very limited, and practically nil in winter.

Solar cars have achieved some amazing feats, of course, but the successful machines utilise a large surface area of priceless aerospace-grade panels to optimise power input, with sophisticated motors and lightweight construction to optimise performance. And it’s no coincidence that the annual solar challenge takes place in the Australian desert… But as we all know, cars are notoriously energy-hungry machines, and we can do a great deal better with other modes. Motorcycles and planes are even worse in the power requirement/surface area stakes, but low-speed motor boats are feasible, and a few have been produced. Best of all, though, is the humble bicycle – true, it offers a modest surface area, but it has an even more modest power demand.

…bicycles, like cars, spend a lot of time sitting in the sun, going nowhere…

The power requirement of electric bicycles varies a great deal, but we know from experience that the Panasonic-equipped Giant Lafree is the most efficient currently available, with a mean consumption of less than 100 watts under typical conditions.We could generate 100 watts from a panel measuring about 1.5 square metres, which would certainly be feasible on a faired recumbent. However, with a battery on board, there’s no need to generate all the power, particularly as bicycles, like cars, spend a lot of time sitting idly in the sun, going nowhere. In practice, a much smaller panel generating 20 watts would more or less recharge the Lafree battery during a long sunny day, giving a daily solar range of nearly 20 miles. If one were to start the day with a full battery, the solar boost might extend the non-stop range from 20 to 24 miles, or anything up to 40 miles spread over the course of a day, provided the bike was left in the sun between rides. A solar charger of this kind might also enhance the battery life, thanks to reduced current drain on hills and a steady trickle charge, rather than a daily boost. Suddenly the technology looks more practical.

In Practice…

uni-solar-usf-5-solar-pvThe bad news is that solar panels are generally unsuited to use on bicycles. Although the panels themselves are light, they’re fragile too, so they’re usually housed in a heavy rigid frame.A few lighter, flexible panels are produced for boats and mobile homes, and although these are not particularly space-efficient, we must concentrate our search in this area.

Taking weight, space constraints and price into account, a pair of Uni- Solar flexible USF5 panels look like a good compromise.The two panels weigh 1.1kg, measure 44cm x 54cm and cost around £180 in the UK. Rated output is 300mA at 33 volts, or 10 watts – only half the power required to refill the battery during the day, but enough to provide some reliable data. By comparison, a spare battery for the Lafree would give twice as much mileage (in all weathers, of course), but cost a little more and weigh three times as much.

I’ll be fitting the panels to A to B’s long-term Giant Lafree in the next few weeks, and reporting back in subsequent issues. In terms of practicality, this is cutting edge stuff:We The Uni-Solar USF5. The border is unproductive, but gives aim to find whether panels are the panel some protection from inevitable knocks practical in our gloomy climes, or whether the weight and bulk cannot be justified for everyday use.

Perhaps carefully angled panels on a south-facing roof would be more effective? Or a combination of the two systems? More in the next issue.

dahon-presto-p3-folded

Budget Commuters

Dahon Presto P3

The Presto is probably the most conventional looking of the three

If you’re a regular commuter, whether by train, car or bus, you could almost certainly use a quality folding bike.You may not realise that yet, but it’s probably the case nonetheless. A folder makes commuting more flexible, allowing you (for example) to hop off the train in a cheaper fare zone, take a different route when your line is closed, eliminate tube fares or station parking, or park- and-ride from the edge of the city. Everybody should have one, and the classic machines include the Brompton, or – if you prefer 20-inch wheels – a Dahon (typically the Helios), or the Giant Halfway.

None of these bikes are cheap, so we’re looking at three cut-price compacts: the Pashley Micro-Luxe, still only £295, the new Dahon Presto P3 at £345, and Brompton’s bargain basement C3 at £375. All three bikes have 16-inch wheels (the larger ‘British’ 347mm size on the Micro and Brompton, and smaller 305mm on the Dahon), and all fold into compact packages, although not quite the bus-friendly folded size of the Brompton L-type. But they’re much cheaper, and on paper at least, should do a similar job. Is this true?

It’s been a few years since we produced a group test of folding bikes, and we’ve never tried the Brompton C3, although the Brentford factory has been quietly producing this cheaper variant for several years. Basically, the C3 is a Brompton frame with inferior bits and pieces hung on it, with the exception of mudguards (there aren’t any), and it comes in any-colour-you-like as long as it’s red. A word of caution – we wouldn’t recommend buying a C3 with the intention of upgrading it to L6 spec when funds allow, because the cost would be prohibitive. However, the C3 accepts Brompton’s pannier system and with these sort of extras, it might be worth considering as a fine weather commuter bike.

The Presto is new, and one of a bewildering range of new and revamped models to arrive from Dahon’s Chinese factory in recent months.The frame is effectively a smaller version of the 20-inch Helios frame we admired in A to B 31, but almost everything else is new, or at least, new to us.

The Micro is one of the great survivors of the folding bike world, having been in more or less continuous production in a number of guises since its birth in Birmingham back in 1976.The bike has been produced by Pashley for a number of years now, but the company has made few changes, other than safety modifications and a change to a SRAM hub when Sturmey ceased to exist. Our test bike is actually a few years old, but can be treated as a new machine in most respects.

The Contenders

Despite their diminutive size, all three of these bikes can be adjusted to fit most riders, with the Dahon being the most adaptable and the Micro the least. If you’re very tiny, you’ll be delighted to hear that the Brompton can be ridden with the saddle only 65cm from the ground, but less pleased to hear that the Micro only drops to 74cm, and the Presto to 85cm. For the very tall, it’s more or less the other way around – 94cm for the Micro or Brompton and a useful 101cm on the Presto. Just to confuse matters, the Brompton leaves the factory with the saddle right forward and as low as it will go. Reverse the saddle bracket and fix the saddle at the very top of the stem, and you’ll find another centimetre or so, at the expense of a slightly taller folded package.The Brompton is also available with a taller saddle stem, or two-stage telescopic device, but that adds to the cost, weight and folded volume.

Micro Luxe Folding Bike

The Micro-Luxe - quirky looks and handling

Handlebar height is only adjustable on the Presto, in a range 84 – 101cm, the others being fixed at a reasonably comfy, if rather upright stance. Reach from the saddle to the bars obviously varies with saddle (and/or bar) position, but it’s greatest on the Presto at 52cm – 60cm (considered too much by some), and around 48 – 51cm for the Micro and Brompton. Generally speaking, the Presto is a bit stretched for the very small, but the best choice for those of six-foot plus.

Weight is almost as important as ride quality with compact machines, and when you’ve dashed from Platform 1 to Platform 14 a few times, you’ll begin to appreciate why.Winner here is the Micro at 11kg, followed by the Brompton at 11.3kg, and the light alloy, but more generously equipped Presto topping the scales at 11.6kg. If they all sound a bit heavy, Pashley claims it can produce a 9.5kg single- speed version of the Micro to order; Brompton says the C3 can be trimmed to 10.7kg with some pricier bits, and Dahon has just withdrawn a delightful single- speed version of the Presto, weighing a claimed 7.9kg.You might find one if you’re lucky, but you’ll have to pay £450. Most of the bigger, better folding bikes cost more than this, and they tend to weigh more too: 11.4kg for the Brompton L3, 12.2kg for the Dahon Helios, and 12.6kg for the Giant Halfway.

…if you can live with these quirks, you may be  very happy together…

 

Ride

Although it bears a family resemblance to the very sweet Dahon Helios, the little Presto proved a bit disappointing. Despite having the lowest gear ratios by a small margin, the smaller 305mm tyres make the bike feel slightly over-geared and lethargic.This effect is made worse by a degree of lateral flex in the main frame tube. On the positive side, the long 102cm wheelbase helps to smooth out any choppiness on poor road surfaces, and the saddle stem feels rigid fore and aft, so you can put in plenty of effort, provided you avoid twisting the machine.The handlebar stem would be rigid enough, but the joint feels loose, and despite greasing the moving parts, and adjusting the stop, we couldn’t eradicate this. And once in a while, the hinge appeared to latch, but was only partially fastened. Generally speaking, if the hinge mechanism is hidden, as it is here, it’s worth checking that things really have engaged properly before riding away. Of Doctor Hon’s many designs, this is not the best.

The Micro is a strange beast. Initially it feels highly unstable (‘wonky’ is a common complaint), but if you persist, that impression soon fades.The wonkiness is partly the result of a rather spindly front end and short 89cm wheelbase, but mainly due to the bars being well forward of the steering axis. Consequently, the handling is always going to be strange, but most people learn to live with it.The frame is solid enough at the rear, but that stem really is as frail as it looks, so the only practical technique is to sit upright and spin the pedals smoothly, putting as little weight on the bars as possible: much the same as riding the old Bickerton. If you can acclimatise yourself, the Micro can be quite a rewarding bike to ride, but the short wheelbase means you have to take a little care, and rough surfaces are beyond its capabilities. If you can live with these quirks, you may be very happy together, but if you can’t, you’ll hate it.

brompton-c3

The Brompton C3 - economy version of the Brompton L and T models

The Brompton is the most rigid of the three, with something of a ‘proper’ big bike feel, and despite much higher gearing (still some 10% lower than the conventional Brompton), it feels sprightly and fun to ride.At 101.5cm, the wheelbase is almost as long as the Dahon, the frame is stiff, but entertainingly lively, and the rear suspension absorbs bumps quite well.The result is a machine that handles tricky canal towpaths and off-road trails with surprising ease – the lack of mudguards helps here, although lower gearing would be an advantage if the bike was to spend any time off-road. Read more about action ac.

dahon-presto-p3-2None of these bikes are great hill-climbers. Despite a bottom ratio of 44 inches, the Brompton does best, because it’s rigid enough for you to stand out of the saddle on steep hills.With a bottom gear of 40 inches and a reasonable frame, the Dahon isn’t far behind, but the little Micro is limited to the sort of gradients that can be climbed with your bottom very firmly on the saddle. Standing out of the saddle on a Micro is an acquired art, and not an especially productive one.Top speed depends on how fast you can twiddle the pedals with a 75-inch top gear (Micro and Presto) and 82-inch gear (Brompton).

The best sixteen-inch rolling resistance is broadly comparable to a typical big-wheel bike these days, but there’s no special tyre technology on these budget machines.The Brompton wins the booby prize, with 1960s- vintage Raleigh Records, although the other models are fitted with the company’s own excellent tyres these days.The Micro used to come with useless Swallow tyres, but they went out of production, forcing Pashley to spend a few quid on their replacement – the good-all-rounder Schwalbe Marathon. Get the feeling the Micro is starved of investment? Dahon fits a pair of Kenda Kwests – another safe bet. In terms of rolling resistance, measured on our standard test hill, all three managed a shade over 13mph, or about one mile per hour behind the best 16-inch flyers. If anything, the Dahon seemed to have a slight edge, despite having the smallest tyres.

Brakes

Never were a group of bikes more widely separated. Both the Brompton and Micro are fitted with horrible side-pull callipers that should have become extinct several decades ago, but seem to have survived in this base-model Lost World.This, together with nondescript levers and long cables of dubious quality, results in some truly scary braking performance, even in ideal conditions.

Worst of all is the Brompton – mainly because the callipers and levers are so flexible that a crash stop results in the levers meeting the handlebars long before an acceptable brake force has been applied. On our test bike, the rear brake managed a stop of .27G (some way short of locking the wheel), while the front achieved a desultory .35G – not much risk of being thrown over the handlebars there. Heaving both levers right to the bars produced a panic stop of .48G, which just locks the rear wheel.That’s a sufficiently poor performance to be dangerous with heavier riders, or in busy city traffic. Once again, all other Bromptons are fitted with much improved dual- pivot brakes.

brompton-c3-brakes

The Brompton C3 has the worst brakes of the group. Note the mounting block for the carrier system

The Micro has marginally better Tektro levers, but similar Saccon callipers to the Brompton.The rear brake did even worse, with a mean performance of only .25G, a rotten stop, made only slightly more interesting by a strange harmonic, which runs up through the frame and into your private parts. Strange but true. The front brake lacks the entertaining massage effect, but makes up for it with a modest stop of .52G.That’s not enough to lift the rear wheel, but considering the short wheelbase, it’s probably close enough for comfort, so improved callipers wouldn’t C3 necessarily make the bike any safer. Both brakes resulted in a stop of .6G, which is adequate, but far from heart-stopping.

In marked contrast, the Presto comes with Dahon-branded V-brakes, excellent Jagwire cables and Promax levers.The result is brake performance as close to a hydraulic system, in terms of performance and feel, as cable-operated brakes are likely to get.The cables flow through their guides almost without resistance, and when the brakes bite, they do so progressively and with real power.

The front to rear weight distribution must be good too, because we achieved an excellent .41G stop at the rear before the wheel locked up.Yes, that’s almost as good as heaving on both the Brompton anchors. Obviously there’s enough power here to lift the rear wheel with ease in a front brake stop, but the long wheelbase keeps things well under control. As the wheel starts to lift, the front brake hits a maximum of .75G, which is the best result we’ve achieved in our short experience of G-meters. It’s also better than the Orbit Orion tested elsewhere in this issue, which rather overturns the widely held belief that small-wheel don’t stop as well as big ones… Given similar technology, they stop just as well, or better.

Accessories

Dahon again, by a wide margin. The Presto has a pair of Next folding pedals (strange, because it only needs one), a smart little rack, a bell and a stand.The Micro has a pair of frightful VP-112 folding pedals (strange again) and a stand.The Brompton has nothing, except that wonderful Brompton frame. In terms of aftermarket fitments, there’s a mounting plate for the Brompton front carrier system, and another useful accessory is the folding pedal. But that comes as standard on the L- or T-type, together with proper brakes, decent tyres and so forth…You pays your money and takes your choice.

Folding

dahon-presto-p3-folded

The Presto is the most difficult to fold, producing an untidy package

In folding tests, the Brompton always wins. The secret is a clever frame that folds and rotates back on itself around the steering head, producing easily the neatest, and marginally the smallest, of the three folded packages at 124 litres (4.4 cubic feet). And that’s with the left-hand pedal sticking out. Once you’ve learnt to do things in the right order, which is essential, it’s all very  straightforward, with a quick-release for the saddle stem and two big user-friendly U-clamps on the frame and stem joints.The folded package is marginally taller than the others at 56cm, and about the same width at 35cm (thanks to that protruding pedal) but at 60cm, it’s much shorter.

The Dahon frame folds around a robust-looking hinge, while the other (less satisfactory) hinge allows the handlebar stem to tuck down between the two frame halves. A quick-release drops the saddle stem, which can be left rather untidily in place or removed, while another quick-release on the handlebar stem must be loosened and re- tightened to allow the bars to assume their most compact position.This tricky manoeuvre proves the bike’s Achilles heel and results in all sorts of confusion for those unfamiliar with folders. A lock-nut on the quick-release would help, because the adjustment keeps changing, and needs constant fettling and fiddling. Get it wrong and the bars can drop right out of the folded package, or worse still, swivel round while you’re riding away. Get it right, and the Presto produces a near C3 folded package of 129 litres – 75cm long, 35cm wide, and 49cm tall (with the saddle stem stowed between the frame halves).

brompton-c3-folded

The Brompton is by far the neatest and quickest folder

The Micro is the simplest and/or crudest design, relying on a pair of rather frail- looking Brompton-style hinges, allied to the simple frame geometry of the Dahon. However, the Micro can be folded in any order, because the bars end up on the outside of the package – a much easier concept for beginners to grasp.There’s no handlebar height adjuster, and a simple quick-release to lower the saddle stem.The resulting package is a little wider than the Dahon at 36cm, taller at 51cm, but shorter at 71cm, producing a slightly bigger package of 130 litres.

Once folded, the Brompton is effectively locked together until the next time the saddle is lifted.The Micro and Dahon are not quite so clever, the Micro being secured in the folded position with a couple of domestic water- pipe clips, and the Dahon with an easily mislaid bit of Velcro.There’s no obligation  to remove the saddle stem with either, but if you don’t, the package will be taller: 64cm for the Micro (producing a 168 litre package) and 68cm for the Presto, resulting in a rather cumbersome 178 litres.

micro-luxe-folding-bike-folded

The Micro is the crudest design, but it works reasonably well

On paper, the three bikes might appear similar, but folding the Brompton is much more consistent. Once you’ve got the hang of it, the elements clonk down into exactly the same place each time and lock in place. Unfold the Brompton, and everything goes back where you left it the last time the bike was used. It’s a simple, reliable mechanism that can be repeated time and again, without trapped fingers or cables, and it’s as easy to do on a cold wet night as your train arrives, as it is on a Sunday morning in the park.

Fit a folding pedal to the Brompton, and the width comes down to 27cm, reducing the package size to 90.7 litres, or about 3.2 cubic feet.With a few compromises on riding position, caravanners, pilots and yachtsmen with cramped locker space can jiggle the length, width and height down a little further, producing a folded package of less than 85 litres, or three cubic feet.

Folding times are largely irrelevant in the leisure market, but the stuff of missed appointments and supper (or partner) going off the boil for commuters. Once again, the Brompton dominates: Provided you ride the bike with the saddle at its upper stop height, the C3 can be folded up or down in about 12 seconds (we managed a record of eight, but we know the bike well). Unfolding takes a second or two longer, because of the need to set the saddle alignment, but thanks to a height stop, everything else should wind up precisely in place.The Micro is superficially similar to the Brompton, but the need to remove the saddle stem adds a bit of time, making about 24 seconds in all. Unfolding takes about the same time, including setting the saddle stem height and alignment.

The Presto languishes in the 50 second zone – mainly because of the need to loosen the handlebar stem, then re-tighten it in the folded position; remove the saddle stem and stow it; then wrap the Velcro round. Unfolding can take even longer, because both the saddle and handlebar height and alignment must be set before riding off.

Conclusion

Before reaching our own conclusions, it’s worth summarising the views of our small panel of ‘conventional’ cyclists. At first glance, the Micro was dismissed, because of its dumpy appearance and short wheelbase.The slightly odd-looking Brompton was also treated with suspicion and the Dahon faired best, being considered the smartest and most conventional of the three bikes. A brief ride tended to produce much the same result – Dahon on top, closely followed by Brompton, with the Micro trailing behind. But folding changed everything, with even the beginners rating the Brompton best of the bunch, the Micro second, and the Dahon last.

Are these machines practical commuter bikes? Our advice with the Micro is to try it and see if you can live with the quibbles and quirks. If you can, you’ve found a compact, light and very economical folding bike. If you can’t, you’ll have to spend more…The short and the tall will prefer the Dahon, thanks to its adjustability, but for most commuting purposes, the folding is too clumsy, although a simple car park-and-ride journey shouldn’t prove too taxing. But if you want a Dahon, the 20-inch models are cheaper, easier to fold and much nicer to ride.

And the Brompton C3? It’s a jolly little bike, but you get the feeling there’s a much better machine trying to get out, which of course there is: the Brompton L-type.The L3 costs 25% more than the C3, but it’s probably the best commuter bike on the planet, so there’s no contest. Save up for the real thing…

Folding Panniers

Folding Panniers

Folding PanniersIf you do practical things with a bicycle, like shopping, you’ll know all about panniers – those gloomy bags you can’t live with, and can’t live without.When you need them, they’re usually too small, and when you don’t, they’re invariably too big. So, how about folding panniers? A very A to B solution, we thought.

Folding PanniersThe theory is admirably simple: a pair of metal baskets with hinged bases and sides. For 90% of the time, the panniers are wind-cheatingly slim, but get to the supermarket and – flick, flick, flick! In a few seconds, you’ve created two rigid containers measuring 18cm wide by 21cm deep and 32cm long. Oh all right – 7″ x 81/4″ x 121/2″ in real units (yes, we’re reverting).That’s big enough for 16 tins of cat food plus a box of Friskies each side – a total load I of around 13kg.

Get home, feed Tibbles and the process can be reversed – the slim-line versions standing out from the rack a mere 2cm each side (just under an inch, gran).

Folding Panniers LoadedAny disadvantages? The panniers are heavy (2.4kg the pair), and they can be noisy, particularly when empty, but a well placed bungee cord should solve that one. There’s no protection from rain or pilfering either, but no-one ever claimed they were suitable for touring. Longevity? Hard to say, but these are the sort of extras that can be reconstructed with a pair of pliers and a twist of copper wire. Speaking of which, we found the crucial clip that holds the assembly shut needed a bit of tweaking, and the mounting clips were happier on a thin steel-framed rack, although they worked perfectly well on a modern alloy rack with 8mm stays.

One slight grumble on a big-wheeled bikes (or ‘cumbersomes’ in folder-parlance) is that the depth of only 21cm wastes a lot of productive space, but shoe-horn the panniers onto a small- wheeled folding machine and they begin to look seriously space-efficient.

The panniers fit just about anything, and will fold away with the bike on most, including the majority of Dahons, and the Pashley Micro (provided you have a rack, of course).You can only get one on the Brompton T-type (although folded size is unaffected), and we think two could be squeezed on to the Airframe. Besides folding, you also need to watch the heel/pannier clearance, which can be tight. But mounted so close to the ground, even a 13kg load has little effect on handling – another plus for small-wheeled bikes. Need to carry something really long? Simply strap it across the top. Good, eh?

As so often happens, we started sceptical but rapidly warmed to folding panniers, and found ourselves using them on a regular basis.This would be a genuinely useful accessory on a folding bike used as a boat tender, or similar. Wherever storage is at a premium, but there are big loads to carry once in a while.

Orbit Orion

Orbit OrionTests of ‘conventional’ big-wheeled bikes are rare in A to B, because we prefer to concentrate on more interesting things, but the concept of a really well-equipped commuter machine was quite tempting.

Everyday bikes, it seems to us, should be like everyday cars – practical, reliable and safe. As most regular cyclists will know, the reverse is often the case. Most bicycle lights are poor and other essential equipment is either missing or unreliable. Salesmen deliver stacks of gears, but within a few weeks the indexing starts to go wrong, the chain has worn out and that enthusiastic return to cycle commuting begins to feel more trouble than it’s worth.

Orbit’s new Orion (‘the best commuting machine yet made’, says the company) is a brave attempt to sell a ready to ride, fully-equipped commuter bike. In essence, it’s a custom-made alloy frame in ladies or gents styling, kitted out with some really good (and hopefully reliable) componentry – a solid, practical everyday package.

Riding

We’re not really the best people to ask about big-wheel handling.This one seems jolly good, although the alloy frame feels a bit dead and stodgy compared to steel, and at up to 14.2kg, it’s on the heavy side. Rolling resistance is good, handling is adequate (no- one fell off), and that’s about the limit of our expertise, and very possibly your interest.

Orbit OrionGears are either Shimano 2×9 derailleur or – much more interesting – a SRAM 7- speed hub.The German-made SRAM 7-speed is probably the best multi-gear hub (and will remain so unless the Sturmey 8 proves to be very good indeed). Since the demise of the frail but elegant Sturmey Archer 7-speed, the SRAM’s only competitor has been the Shimano Nexus, which it comprehensively outshines, whatever your local Shimano agent might say. Gear range is wider (284% against 244%), efficiency is higher, particularly in the low gears, and wheel removal doesn’t involve blood, sweat and tears.

Our example is slightly marred by rather tight and graunchy mechanicals, which are stiff enough to cause some drag, but we’ll put that down to the fact that it’s new. Less forgivable is SRAM’s twistgrip, which causes plenty of grumbles. Unusually, the SRAM operates with a rigid (as opposed to woven) push/pull gear cable, terminating in a shifter box on the hub axle. In theory, this eliminates problems with weak return springs, because it doesn’t need any, but the change can be notchy and vague – something that gets worse with age and maltreatment. In this case, the vagueness in the cable is made worse by a considerable amount of play in the gripshift. Finding a gear is like fishing in murky water – you never quite know what you’re going to drag up.

On the positive side, the hub changes smoothly, and the gear ratios (although rather oddly spaced) are a good compromise, spanning the range 33 to 93 inches. An easy sprocket change would give a lower or higher range, according to taste. Against a derailleur, the SRAM should give years of trouble-free service, the wheel will be stronger, and the chain and sprockets will last better too, because everything should be in perfect alignment all the time.The chain also gets a bit of weather protection from a rather wimpy chainguard, which obviously protects your clothes too.

If you can’t live with hub gears (and we strongly recommend that you change your mind), Orbit are also building a Shimano Nexave 2×9 version of the Orion.These derailleur things are quite common on bicycles, we’re told: two (or more usually three) chainrings, plus a cluster of gears in the rear wheel where the spokes ought to be.The advantage is slightly improved efficiency over a hub, but the disadvantages run on and on: unpredictable shifting, short component life, no chain guard, a weak wheel assembly, no gear shifting at the traffic lights, and so on and so forth. For some reason, the current fashion is to cram more and more cogs onto the rear wheel – nine in this case.The result is, er, 18 ratios, which sounds quite exciting, but the degree of overlap between the high and low ranges is so vast that you’re actually left with eleven. In fact, the lower range, spanning 27.5″ to 85″, would almost suffice on it’s own in city traffic – the high range of 37″ to 115″ being largely superfluous until you hit the open road.The overall impression is that the bike is rather over-geared.

…the lights are always ready for action… This is a great safety feature…

Given the gear indexing problems with so many tightly spaced cogs (we never got the system to work 100%, even after careful adjustment), we wouldn’t suggest a 2×9 for commuting.You could achieve much the same thing with a 2×7, using either a derailleur or (better still) a 7-speed hub at the rear end.

The Avid V-brakes are good, though not as good as some.We managed a typical rear wheel stop of .3G, with a slightly disappointing .65G at the front.The rear cable is a bit sticky; something that’s not helped by an out-of-true wheel on the derailleur bike (ah well, comes with the territory, you see).

Accessories

Orbit Orion Bike LightThe most interesting technical advance on the Orbit is the state-of-the-art lighting system – Nexus automatic hub dynamo, Hella FL980 front light and Basta automatic tail light. Our first taste of auto lights (see Giant Lafree Comfort, A to B 31) was less than satisfactory, because the Nexus system would only turn itself on after a stop, which made it useless for tunnels, or gloomy avenues of trees. On the Orion, the very similar system works perfectly – the hub absorbs little energy during the day, but as soon as the detector senses low light levels the front lamp clicks in, and stays illuminated for as long as required. That might be ten minutes, or all night – no dynamo to work loose or seize up, and no batteries to replace.

The Nexus hub provides enough oomph to give strong illumination down to a fast walking pace, and when you do come to a stop, a single yellow LED (powered by an internal 9-volt battery) provides adequate standlight illumination for a few minutes. Or it should, but one of our test lights jammed on, eventually flattening the battery.The Basta rear light is completely separate, so there are no troublesome cables or earthing worries.Two AA batteries provide plenty of illumination and again, the system is fully automatic, sensing both darkness and movement.

Orbit Orion Bike Rear LightWould we now recommend auto lights? Once you gain confidence that the lights really will do what they’re supposed to, this is a good system and a great safety feature. Few cyclists bother to stop and turn on their lights in heavy rain, or generally poor lighting conditions, but most motorists do, and quite rightly so.With the Nexus/Hella system, the lights are always ready for action.

Orbit Orion Bike Otherwise, accessories are a bit thin.The bike comes with Pitlock skewers (see A to B 34) to help keep all the expensive components in place, but if you’re a forgetful numbskull too, you’ll be constantly leaving the key at home – big problem if you need to remove a wheel or lend the bike to a shorty.

Pumps don’t seem to be fitted to bikes any more, but the Orion has sensible Schwalbe Marathon Slick tyres, combining reasonable rolling efficiency (15.3mph on our test hill) with a degree of puncture resistance. Rims are Alex G2000, which Orbit claim to be strong enough for tandem use, and we’ll have to let them be the best judge of that.The mudguards do what they’re supposed to do, but clearance is tight enough for stones to get drawn noisily around once in a while.

The oddly-named Bor Yueh rack (Mongolian perhaps?) is suitable chunky, but if you’re commuting to work in Epping rather than transporting a Yurt across Mongolia, you’ll probably want to augment it with the Klickfix (or indeed, Brompton) pannier system.

Our biggest grumble was the lack of a stand, which proved to be a mild, but ongoing, source of frustration in our time with the bikes. A must-fit accessory.

Conclusion

Would we ride to work on it? No fault of the Orbit, but we probably wouldn’t. For a longer commute we generally mix folder with train or bus, and for shorter or hillier routes, we’d probably choose an electric bike. But we’re the wrong people to ask – plenty of cyclists enjoy a good ten-mile thrash to work in the morning, and if you want a quality component package, there’s no doubt this is a suitable machine, if not the most suitable on the market. Our advice, though, would be to go for the hub gears (you knew we’d say that, didn’t you?) and for some reason we all preferred the gents frame.

Kickbike City Cruiser

kickbike-city-cruiserWe test bikes with big wheels and we test bikes with small wheels, but we don’t often test machines with a big wheel at one end and a small wheel at the other. No pedals either.

The Kickbike is the sort of thing that pops up in those futuristic ‘ideal world’ cycling tableaus that occasionally appear in the less cynical cycle magazines. In principle one size fits all, and there’s sufficient street-cred for young Norman to hang out on the mall, the sort of practicality granny demands for cruising the shops and enough speed (down hill at any rate) for dad to scoot to work.We’ve tested the City Cruiser model costing £190.The company also produces a ‘touring’ Sport Classic at £200 and a lighter, more aerodynamic Millennium Racer at £230, with an off-road job due in the summer at a rather awe inspiring £250. Still, there are plenty of people willing to spend £250 on dafter things than an off-road scooter, so it’s bound to go down a storm.

What and Why?

A Kickbike is effectively a bicycle, stripped of drive system and somewhere to sit, leaving a very large scooter.The bike has a 28-inch wheel at the front and 18-inch at the back (fitted with the 40 x 355mm Cheng Shin tyre from the Birdy), which gives it something of the look of a Penny Farthing, but without the leg-over problem, because there’s nothing to get your leg over.

The Finnish designers suggest all sorts of applications from racing (yes, some clown has set a 38.9km/h record); touring (another banana has ridden more than 300 miles in a day); and BMX stunts (no records for this one). But in practice, this is a flat-country, short- distance, shopping or commuting machine.The UK importer claims that the Kickbike can be kicked for ‘20 miles… on flattish terrain in about 21/2 hours.’ With practice, you might achieve this sort of thing, but where a bicycle would involve a lot less effort, one is tempted to ask ‘why?’.

…where a bicycle would involve a lot less effort, one is tempted to ask ‘why?’

‘Why?’, we soon discover, is a common question. According to Kickbike, scooters are legal on footpaths as well as roads, which could help to broaden your route-to-work options, although it won’t make you any friends amongst pedestrians.Without saddle, pedals and other drive system paraphernalia, a Kickbike is also lighter than the equivalent bicycle, but not by very much. Our City Cruiser model (complete with front basket) weighs 10.4kg – a clunking 1.4kg more than claimed.

The wheelbase is quite long, at 112.5cm, and that, combined with the large front wheel, means that manoeuvrability is not what it could be. At this point another ‘why?’ looms…The 18-inch rear wheel is quite useful (see ‘leg-over’ above), but we’re at a loss to explain the big ‘un, which adds some 12cm to the length and a great deal to the turning circle.With an 18-inch front wheel, there’d be room for a bigger, lower (and thus more stable) load basket, and the bike would be both lighter and more manoeuvrable. Still it all looks very attractive, which is half the battle. Kickbike also makes the perfectly valid point that elimination of chains and cogs means no grease and oil on your clothing. And the step-thru platform and well-enclosed wheels allow you to ride to work wearing pretty well anything, from outrageous flares to diaphanous floaty numbers or shorty minis… all those things you’ve been dying to wear on a bike, but didn’t dare.

Kickbike City CruiserThe gear ratio depends on the length of your legs and how muscle-ly your thighs are. Initial acceleration is well up to hub gear standards, but speed rapidly tails off, where a bicycle keeps accelerating.The practical terminal velocity on the flat is around 7mph, although ten is manageable for short distances, and speed can sail up into the twenties on steep down grades, especially if you have the nerve to squat down and assume a wind-cheating position behind the front wheel.The ideal situation is a gentle down gradient.We recorded a reasonable rolling performance of 14.5mph on our test hill, which is about half way between 18-inch and 28-inch performance, less the extra wind resistance from standing up. Progress on the flat can be reasonably sprightly too, with a following wind, but going uphill is hard work, even on modest gradients. If you’re not used to the kicking action, you’ll be doing a lot of walking.

Handling takes a bit of getting used to compared to a bicycle, although we never found the limit. At speed, the handlebars feel as though they are about to develop a ‘shimmy’ or wobble, an impression that rather detracts from the otherwise effortless progress downhill. Another interesting impression is the softness of the ride – this turns out to be flex in the frame, which bends by a centimetre or more on bumps.That’s only a problem if you’re a stickler for precise steering geometry and other esoteric things. More serious is the very limited ground clearance under the platform – 6cm unladen and up to 1cm less under a fatty.That’s low enough to ground on road humps and the like.

kickbike-city-cruiser-2The turning circle of the Kickbike is much greater than a small scooter, and big even for a bicycle, which is rather disappointing. It can be turned in three metres, which is adequate on the road, but rather cumbersome on the pavement. Manoeuvrability is also hampered by the lack of a saddle, because on a crowded pavement you can’t easily swing the bike around.The technique is to hook your foot under the frame and lift it round.

In practice, a 16-inch folder will turn faster and quicker than a big scooter like this. It probably won’t be as stable though.Thanks to the powerful gyroscopic action of that big front wheel and the low platform, the Kickbike feels reasonably secure. But with no saddle between your legs (in other words, no means of bracing yourself), riding one- handed is tricky.

With a pair of Alhonga dual-pivot callipers (yes, they’re the predecessor to the current Brompton design) braking is powerful and reliable, although Brits should treat the levers with caution, because our Kickbike arrived with continental-style reversed cables. We managed a stop of .34G with the rear brake, which is well up to bicycle standards. At the front, the rear wheel tends to lift with a stop of only .69G, which is on the low side – partly because of a lack of weight at the back of the scooter, and partly because, once again, the rider tends to get thrown forward, because there’s no saddle to brace against. Squat down and back (not something you’d have time to do in an emergency, of course) and the maximum stop can be as high as .8G.The limit here is the brake callipers, which aren’t really powerful enough, and the brake blocks, which tend to twist in the calliper arms under severe braking.

…a full complement of disadvantages, most of which were licked in about 1890…

Accessories

A bit limited.There’s a little bell which goes ping in a most satisfactory manner, and a useless vestigial stand that serves only to reduce the already limited ground clearance. Even without a full load in the basket, the stand won’t hold the machine up, unless the front wheel is turned clumsily to full right lock. And with no saddle, it’s difficult to lean the Kickbike on posts, tree trunks, traffic wardens and the like – a major disadvantage at the shops, you might think. The basket is useful, but as we’ve said, on the small side, so don’t expect to carry home anything bulkier than a small box of cereal and a couple of litres of milk.

In purely practical terms, there’s nowhere to mount lights either, although that need not be an insurmountable obstacle.The mudguards are good, but by the very nature of scootering, wet feet are guaranteed if the weather’s dicey.Talking of water, the Kickbike comes with a mounting for a water bottle – are they serious?

Conclusion

All things considered, it’s hard to imagine a day-to-day commuter scooting to work. Scooters come with a full complement of disadvantages, most of which were licked in about 1890 with the arrival of the dear old safety bicycle.The odds are stacked even higher against the scooter today: a compact folder will go further and faster, yet turn on a sixpence and fold away at journey’s end. On the positive side, a scooter is a good way of exercising muscles that wouldn’t normally see much use walking or cycling (Ow! We can vouch for that), provided you don’t expect to travel any distance.

Foolish young things will probably buy the Kickbike on looks alone, but stuff it at the back of the garage after a week, and good luck to ‘em.We’re not convinced the machine has a future as a commuter steed, and the jury remains out for the little-old-lady market. As one little old lady succinctly put it, ‘I could use that! I walk up hills anyway’.Then, after a moment’s thought, she added, ‘But I do like a seat for coasting down the other side!’ And that sums it up rather well.The question remains, ‘why?’.

Ezee Forza

ezee-forza-electric-bikeWe’ve talked about the evolutionary aspects of electric bicycle development before. And, love ‘em or loath ‘em, the early years of this new century provide a fascinating opportunity to observe transport evolution in progress. Broadly speaking, electric bikes have split into two groups; the heavy Chinese bruisers, personified by the Powabyke, and the newer gazelles of the genre – light, agile pedelecs, such as Giant’s Lafree.

This month, we’re riding the Ezee Forza, a fascinating hybrid from a small Chinese company that might turn out to be an evolutionary dead end, but might also herald the demise of the 40kg dinosaurs. Manufactured in Shanghai, it’s relatively cheap, but it also offers much of the sophistication and performance previously found only on the most expensive machines.The result is something quite new: decent equipment, light alloy frame, NiMH battery and hub gears borrowed from the Lafree concept, but with a down- to-earth Powabyke-style front hub motor and a potential price tag of around £650.That would put the bike head-to-head with the mid-range Powabyke, but with weight and performance closer to the gazelle evolutionary strand.

Enter the Forza

The Forza has an alloy frame and upright riding position broadly reminiscent of the European-designed Giant Lafree.There’s even a similar characteristically curved frame tube, but unlike the Lafree, the tube curves down towards the wheel. Another difference is the slightly garish polished alloy frame, against the Lafree’s understated enamelled version, and some humungous chunky welds, where the Lafree looks delicately crafted.

…not the lightest on the market, but close, and it offers a lot more performance…

Without the battery, the Forza weighs an acceptable 23.6kg (52lb), putting it mid way between the Powabyke Commuter (27.6kg) and the relatively sylph-like Lafree Twist (18.3kg). But unlike either of these machines, the Forza offers suspension – well, suspension forks and a bouncy seat pillar anyway – so it should really be compared with the Lafree Comfort, which weighs 21.4kg without battery.There’s only a couple of kilogrammes in it, so we’re obviously looking at a fairly skillful weight honing job.

Factor in the battery and the Powabyke weighs close to 40kg, the Forza 29.4kg, and the Lafree Comfort 25.3kg.The Forza isn’t the lightest on the market, but it’s close, and it offers a lot more performance, as we shall see.

Riding

ezee-forza-electric-bike-saddleTypical of Far Eastern electric bikes aimed at Germany and the USA, the Forza has a saddle as broad and flat as a dinner plate, with modest height adjustment of 86-89cm, even before the suspension post has sagged under those decadent western buttocks.We did manage to twiddle the saddle up to 96cm by ignoring the ‘max’ warning, but for those lucky enough to sport a slimline Euro-bot, and lovely long legs, this sort of thing is a bit of a joke. It will also more or less guarantee knee damage, should you put any great effort into the pedals. Forza tell us that production versions will come in two frame sizes.

ezee-forza-electric-bikeThe suspension forks and seatpost are not of the best quality, but they do a manful job, coping with most road conditions. Actually, a fair bit of the resilience seems to come from the chunky 26″ x 1.95″ Kenda tyres, which are knobbly on the edges and smooth in the middle, in true ‘mountain-style’.The bike would go further and faster with narrow high pressure tyres, but it might not be so comfortable.

Brakes are a bit of a mixture – V-brakes at the front and Nexus roller brake at the rear. Under perfect conditions, the brakes are well matched, achieving brake force of .75G (front) and .35G (rear). Our concern is that these two very different systems would react differently to wet or icy conditions – something to watch.

Under way without power, the three-speed Nexus hub feels somewhat over-geared at 46″, 62″ and 85″, but with the motor engaged, the ratios are about right. Noise levels are low by hub motor standards – much quieter than the Powabyke, but a little noisier than more expensive designs, such as the Heinzmann.

Thanks to the confusion over the legality of throttle-controlled electric bikes in the UK, Ezee provided us with a bike that could be used in either pedelec (ie, only when pedalling) or full throttle-controlled electric mode.We should also point out that our bike is very much a prototype, and final control specification has yet to be decided.

The pedelec mode proved most unsatisfactory, switching straight to full power after a second or two, and staying there for a while after you stop pedalling.The brakes are fitted with over-ride switches to cut the power, but in practice, this sort of thing is useless in heavy traffic and can take you dangerously unawares during a tight U-turn, for example.

In throttle mode, the bike proved much more controllable, although once the rear- mounted key is turned to the ‘on’ position, there’s no safety cut-out, so inadvertent use of the throttle will set the front wheel spinning.This should be sorted on production bikes, so it would be unfair to dwell too long on this.

ezee-forza-electric-bike-battery

The Forza has an unusually large NiMH battery, but at 5.8kg it's one of the lightest. The saddle tips forward for battery removal

Safety grumbles aside, once you’re on the move, the throttle gives a nice progressive response and the motor pulls cleanly from a stand without fuss, getting into its stride from around 8mph, and proceeding with some enthusiasm to 16mph, or as much as 18mph with a fresh battery.

Er, isn’t that illegal? Well, yes and no.When 90% of motorists choose to pass our 30mph-zoned gate at 40mph+ and the police have no intention of stopping them, we’re not going to criticise an electric bicycle doing a modest 18mph are we? Unfortunately, Ezee tell us production machines destined for Europe will incorporate a 15mph speed limiter. Perhaps the EC would like to do the same for cars?

Range

The front hub motor is compact, economical and powerful, and the NiMH battery – although tiny by Powabyke standards – offers an impressive 324 watt/hour capacity in a particularly lightweight package.This battery/motor combination results in a cracking top speed, plenty of mid- range torque, and considerable  endurance.  We completed our 17.6-mile ‘mountain’ course in a record-breaking time of one hour seven minutes, thanks to some superb hill climbs, including a long 12.5% (1 in 8) stretch, cleared at a steady 9mph.The biggest problem with a powerful motor is holding it back, particularly on a bike with only three gears – the technique is to use full throttle until the bike begins to slow, then change down to second and throttle back until you crest the ridge. On full power, the motor will try to storm the hill at a ‘late for work’ pace and the battery will suffer.The problem with hub motors (as opposed to crank-driven systems) is that on really steep hills the motor is working more slowly (and less efficiently) than it would like, so a good general tip is to engage first gear, throttle back further still, and do a little more work yourself.The practical limit in this case is about 17% (1 in 6).

…only two come close…the Powabyke Commuter and the Dawes S-Drive…

Having reached our destination without the slightest hiccup or falter, we turned straight round after a nice cup of tea (thanks gran) and did it all again in reverse. Average speed continued to hover around the 15mph mark (yes, that’s the legal maximum for power assistance), until 26 miles, when the first of two low fuel warning lights popped on during a steep hill climb.The indicator has three lights – green, yellow and red, but green stays cheerfully illuminated until the battery is almost exhausted and red never makes an appearance. By 31 miles the yellow light was permanently on, and the end came quite suddenly at 32.8 miles, covered at a cracking average of 14.8mph with excellent fuel consumption of 9.9Wh per mile. Battery replacement will probably cost in the region of £200, giving an estimated running cost (note, we now include 2p per mile for cycle consumables) of 5.8p per mile.

…the Forza is in a class of its own in terms of speed, range and rideability…

How do the figures compare? Running costs are amongst the cheapest we’ve seen, and about the same as the Powabyke. In terms of range, most electric bikes can scrape up to twenty miles these days, but only two come close to the Forza – the Powabyke Commuter did the same mileage at a slightly lower 14.3mph average, while the long-range version of the Dawes S-Drive (now discontinued) managed 48.9 miles, but at a rather lethargic 13.4mph.

ezee-forza-electric-bike-speed-vs-power-consumption

In motor-only mode, the Forza managed a shade under 20 miles on a flattish circuit – about the same as the Powabyke again, and exactly as claimed (35km). If you don’t think that’s remarkable, remember that the Powabyke has a monster 13.4kg battery, but the Ezee battery weighs just 5.8kg… And the average speed (on a wet and blustery spring day) was a consistent 15.5mph for most of those 21 miles, falling to 12mph or so on modest hills and 9mph on a 10% gradient.When the battery eventually expires, the Forza is surprisingly easy to pedal, thanks to a much more rigid frame than the Lafree. Standing out of the pedals is easy on this bike, which is fortunate, because you’ll be doing plenty of it with a 46″ bottom gear. Ezee tell us that production bikes will have the Nexus 7-speed hub as an option – worthwhile if you expect to tackle hills unassisted. But even in three- speed form, the Forza is in a class of its own in terms of speed, range and rideability.

Charging

ezee-forza-electric-bike-rack

A good equipment package - decent rack, 3- speed hub, dynamo lights and full mudguards

With a 324Wh battery, charging is never going to be quick, but the large battery has been paired with a powerful charger – a neat little fan-cooled unit measuring 19cm x 10cm x 5cm and weighing 1.1kg (half of this in the generous three-metre leads). A 90% charge takes exactly five hours, after which the charger reverts to a low top- up rate till morning. Fast chargers can be inefficient, and this one manages only 50% efficiency, so the process generates quite a lot of heat, consuming 600Wh over the five hours (and 16 watts per hour thereafter). Chargers of this kind should not be left connected for too long – we would suggest a maximum of 15 hours.

Equipment

Possibly the broadest package of any we’ve tried, although not necessarily the best componentry.The Forza has a useful rear rack complete with traditional spring-thingey, chainguard, substantial but not overly heavy centre stand, basic but acceptable trip computer and a dynamo lighting set.

ezee-forza-electric-bike-lights-suspension

Front suspension and dynamo lights - all part of the package.

The trip computer works well enough, but if you push the buttons in the wrong order it’s possible to erase everything, which is a bit annoying. It’s also a bit short on functions, offering only speed, elapsed time and mileage, but no average calculation, which looks a bit mean. On the other hand, it’s simple to use and easy to read, and it’s the first standard trip computer we’ve tested, so top marks.

The dynamo lighting system is based on rather crude copies of European products – a shaky-looking bottle dynamo, a neat but remarkably ineffective front lamp, and a workable, but old- tech rear lamp.The dynamo slips and whines for a mile or so until it warms up (and fitfully thereafter), the lamp bulbs look and perform twenty years pre- halogen, and the wiring looks vulnerable at the rear, but it all works, and it’s part of the package.

Conclusion

Our prototype Forza has one or two minor niggles, such as a noisy rear mudguard, and some glaring faults in the control software, but everything else performed well, from the fast compact charger to the lightweight battery and quiet efficient motor.

Weight – both of the battery and the bike – is particularly low, resulting in reasonable economy and sprightly performance.We’re quite convinced that with a few tweaks, the Forza could be a very effective machine indeed.

Should the big manufacturers be worried? If the Forza can sell for less than £700 in the UK, Giant will be under some pressure, but the sheer quality of the Lafree will probably keep it in the top spot. For Powabyke on the other hand, machines as good as this could mark the end of the line.The Forza is (much) lighter and will probably be cheaper. It also looks better, and it offers an impressive list of accessories, from lighting to suspension. Cost, performance and range are about the same, but the Forza recharges in almost a third of the time.Which would you buy?

Letter from America – The Simple Life

letter-from-america-36Henry Thoreau never rode an electric bike – or any other kind of bike, for that matter. He died in 1862, during the American Civil War. Had he lived in our time, no doubt he would have delighted in all the alternatives featured in A to B. He would probably have been a faithful supporter of the magazine, and might have contributed an article from time to time. He would probably have seen that the magazine is about more than bicycles and scooters. It is about sane, sensible living, and he had a few things to say about that subject.

Mr.Thoreau lived almost all of his 45 years in Concord, Massachusetts.That place is sacred ground to Americans who know their history. UK readers may recall that in the 1775-76 era a certain unpleasantness erupted between the troops of King George III and his American subjects. Perhaps Ralph Waldo Emerson described it best in 1835 in his Concord Hymn:

By the rude bridge that arched the flood Their flag to April’s breeze unfurled Here once the embattled farmers stood And fired the shot heard round the world.

Sacred ground or not, Henry Thoreau did not think much of his society. He saw those around him rushing through their lives and doing whatever it took to ‘get ahead’ during the 1840’s and 1850’s, all the while staggering under their burden of debts and obligations. He saw it all, and in his classic book Walden (1854) he observed, ‘The mass of men live lives of quiet desperation’. Later in the book he gave his remedy for all this misery. ‘Simplify, simplify’, he wrote. Mr Thoreau would have been very comfortable with A to B.

Historian David Shi tells us that in the USA there has been a regular shift between periods of excessive luxury and periods of a return to simpler living, which in the early years of the American republic was called republican simplicity.The current name for this return to sane, sensible living is voluntary simplicity.The leading American spokesmen for Henry Thoreau’s ideas today is Duane Elgin. He, in his book Voluntary Simplicity, sees the need to eliminate much clutter and stress from our lives in order to find a life that is, ‘Outwardly Simple And Inwardly Rich’.

Our modern world has given us wealth and convenience beyond the dreams of past generations. It has given us other things, too – workaholism, frantic living, mindless consumption and a never-ending supply of tranquillizers. Something is clearly out of balance, and we would do well to take a close look at how we live.

Mr Elgin’s thoughts are those of Thoreau, updated to reflect the dilemmas of modern life. Like Thoreau, he sees lives of quiet desperation all around him, and like Thoreau, he sees that it does not have to be that way.There are remedies, if we will only adopt them.

A human face for all of this has been supplied by Linda Pierce, a self-described reformed Yuppie lawyer. In 2000, she published the results of her Pierce Simplicity Study, which she titled Choosing Simplicity. It is a survey of 211 Americans: ‘Real people finding peace and fulfilment in a complex world’.

The heart of Ms Pierce’s book is in the responses of these 211 people, 40 of whom were interviewed in depth by telephone. All 211 were invited to fill out the usual forms and check off the usual boxes.They were also asked to add any personal comments they wished about their attempts to find a slower, saner and simpler lifestyle. Most did comment, supplying the author with everything from small note cards to 30-page handwritten letters.

The result of all these efforts provides a fascinating look at people who seem to live largely without quiet desperation. Most live in cities and suburbs, rather than mountain tops. Most have regular jobs and homes or apartments.There is Joe Judge, whose life is quite different from Armando Quintero, whose life is extremely different from Colette Bryant. For all their differences, these people and the rest, report lives of considerable fulfilment. Mr Thoreau might find their accommodations to our modern world a bit odd, but he would probably not quarrel with the results.

There are millions of people all around us who are living differently from the mass of men.You might find it worthwhile to wander into your local library or bookseller’s and meet Duane Elgin and Linda Pierce.They would be pleased to share some thoughts with you. Henry Thoreau will be there too, of course. Modern readers will probably find that his expressions are a bit out of date, and that his thoughts are not. As we all move through these times, it is well to keep in mind an old Chinese proverb:

When the student is ready, a teacher will appear

A to B 35 – Cool trailers!

If you’re lucky enough to own any of the later Folder magazines or early A to Bs, we hope you’ll agree that they really were rather good. In those far-off days – before the two-monthly A to B cycle became a bit of a production line – we spent a lot more time over the writing and artwork.The photos were scratchy black and white, and – pre-internet of course – the audience was small, but the results could be quite entertaining.To mark our fast approaching 100th edition we’re dragging some of these classics out of the archives and remastering them… where possible in glorious technicolour. Do send in your requests… we have most of the original photos, so pretty well anything is possible.

A to B 35 Blog, April 2003, Congestion Charge

A to B magazine, Congestion Charge, Day OneFIRST PUBLISHED April 2003
London Congestion Charge Launch, Rough Guide launch

On Monday, February 17th, the Mole joined the world’s media on the streets of London for the launch of Ken Livingstone’s long-awaited Congestion Charge. This turned out to be something of a disappointment because (a) Ken had wisely chosen a half- term launch date, thus eliminating the school run from the equation and (b) the Mayor had talked up the potential for disaster to such an extent that whatever transpired could only be viewed as a successful launch.

In the event, traffic levels were down a thumping 25%, forcing media commentators into a frenzy of interviews with each other for want of stationary motor cars and grumbling occupants. The Mole spent an equally fruitless morning attempting to track down a small body of protesters, rumoured to be waving placards beside the A3 somewhere south of the river, but all to no avail.

By the evening, a formerly hostile media had changed sides, with even the vociferously anti-Ken lobby giving a wary thumbs up. Yes, the charge gave every appearance of being a discriminatory kick at the poorer motorist, but the media soon grasped what Ken had known all along – that the only people driving into central London at peak times were posh nobs.

Thus, the spin changed overnight, with the Congestion Charge melting seamlessly from an indiscriminate tax on the poor to a democratic congestion buster, clearing the streets of filthy-rich, selfish motorists to make room for the buses that the downtrodden masses had been using all along.

Ken had taken quite a gamble introducing the charge (although nothing like as big a gamble as he had made it appear, of course). But the real loser was arch transport spokesperson and Tory Mayoral candidate-in-waiting Steven Norris, who laid caution to the wind on the eve of Charge-day, announcing that he would scrap the system if elected. By Charge-day +14, with traffic stabilised at 10-15% below its former level (just as Ken had predicted), Norris had grown strangely quiet.

A to B magazine, Congestion Charge launch, Mike BurrowsAmongst the winners on the day was Mike Burrows, who cheekily chose this day, of all days, to publicise his 8-Freight load carriers in the capital, arriving by train with no fewer than three machines, a feat for which we must thank the unrecognised British Rail engineers who endowed the Norwich rolling stock with sufficient luggage space.

Wandering aimlessly through the near deserted streets of Vauxhall, the Mole happened upon a pair of Mark 3 Brox HPVs, billboarding the Toyota Prius, which turns out to be a hybrid petrol/electric vehicle, sensibly exempt from the Congestion Charge. According to Toyota, those signing up for the Prius receive a £1,000 grant from the Energy Savings Trust (see page 9), and save £100 on the road tax and £1,250 on Congestion Charges each year (less a £10 administration fee). Of course, would-be Prius owners could pocket the entire £17,000 purchase price by cycling to work instead – an irony that was no doubt lost on the ad agency concerned.

A to B magazine, Toyota Prius advertisementTwo weeks later, the Mole attended ‘Keeping us Moving’, a conference widely billed as the post-mortem of the Congestion Charge.This cheerful shindig was staged by something called EPSRC, working in tandem with another thing called ESRC. For non- transport professionals, these worthy bodies are composed of charming academics whose role seems to involve finding new and imaginative ways of spending tax-payers’ money.

Rather disappointingly – although entirely predictable, given that the Department for (road) Transport was a primary sponsor – this day of egg-head debate centred largely around motoring matters.The only real difference of opinion being the long running spat between the ‘predict-and-provide’ chaps (now on the ascendancy, in the wake of the government’s latest round of road building), and the ‘demand management’ boys, fighting a desperate rearguard action.

As one might expect, bicycles were off the agenda altogether, and rail conveniently sidelined.The Mole discovered why, when sharing a mid-morning coffee with Professor Phil Goodwin, the government’s amiable advisor on transport affairs. ‘I’ve given up working on rail’, says Phil, ‘…because nothing ever gets done…’

Prof Goodwin went on to pour scorn on his master’s policy of building roads, whilst predicting ever greater congestion: ‘For governments to say this themselves is unprecedented’, says the transport advisor, with a twinkle in his eye. Fortunately, he has a day job. Interestingly, he goes on to predict that HMG will do a U-turn and back the Congestion Charge, ‘…within 16 months, give or take four months.’

At the morning press briefing, the Mole took the opportunity to ask whether the conference might best be described as a crisis meeting? ‘There’s no crisis in research’, proclaimed the egg-heads, as one man. Putting it into practice, of course, is another matter. ‘It’s more an opportunity than a crisis’, chips in one professor. ‘The only way to get research into practice is with a high level political commitment’, adds another, implying, rather woefully, that commitment might be lacking in government circles.

Consequently, Keeping us Moving offered little of interest, but there were a few innovations, such as the Deflatable Road Hump, an air-filled device that deflates under slow-moving traffic, but stands firm when it senses rapid movement. Clever stuff, but will it deflate for bicycles? We weren’t told.

…it deflates under slow- moving traffic… will it deflate for bicycles? We weren’t told…

Clever Innovation Number Two is the GPS-controlled private hire system. London, it seems, has 44,000 mini-cabs, of which only 4,000 are registered – many of the remaining drivers being uninsured, with a small but identifiable proportion being homicidal maniacs into the bargain.

It seems the public interface of the system is a roadside box into which one inserts 50 pence and types a destination. Then, through the action of clever mechanisms that must remain unexplained, a message is sent into space requesting the arrival of a mini-cab. Back on terra-firma, all the registered mini-cabs are buzzing about radiating their position to the same orbiting satellite, and the box duly pinpoints the nearest, then prints and disgorges a ticket indicating its registration number, estimated time of arrival, and the fare.

Not only does the system choose the nearest cab, but it guarantees a registered (and thus, one hopes, user-friendly) driver, and dispatches passengers on a first-come- first-served basis, eliminating any post- theatre unpleasantness.

A to B magazine, Rough Guide Launch, Jason Patient

The Rough Guide launch – photographer Jason Patient salutes one of his images…

Back at the conference, a rare moment of insight comes from Professor Glenn Lyons of the University of the West of England. ‘Public perception of travel modes is drifting further and further away from reality’ says the prof, helpfully explaining that bicycles are now beyond most peoples’ field of imagination and trains are considered expensive and inconvenient, but cars are cheap, fast, secure and reliable.

A to B magazine, Rough Guide launch

…and the view from the balcony

During the 2000 fuel ‘crisis’, Professor Lyons moved quickly, obtaining funding for an emergency survey of motoring habits. This revealed that some 30% of commuters changing transport modes when the pumps began to dry up, with 25% of parents walking or cycling their children to school, although the crisis had little effect on business travellers. ‘Habitual behaviour inhibits mode choice’, sums up the professor with a sigh. In laymen’s terms, given a swift kick up the backside, we could solve our transport ills in days. Roll on the next fuel crisis.

After a satisfactory lunch, the participants took their seats for a blast of hot air from a panel composed of the Great and the Good in transport, chaired by BBC Transport Correspondent Simon Montague. First up for ritual humiliation was Steven Norris, who was reminded that he had promised to ‘scrap the charge’. Norris, ever the politician, replied ‘It’s important to split the principle of charging, which is entirely sensible, from any particular scheme.’ One suspects the problem with the London scheme is that the incumbent mayor thought of it first…

It’s a sign of how far Norris has to squirm that even John Dawson of the Automobile Association spoke kindly of the Charge, accepted that ‘tactical charging’ made sense, and that motorists were generally in favour.

Warming to this theme, a traffic engineer stood up and admitted that he had helped to design the computer model for the layout of Milton Keynes, a town specifically designed around the car, yet now as congested as anywhere else. Was this honest man about to come over to the demand management camp? A conversion on the road to Buckinghamshire? Sadly no – the fellow merely concluded that the residents of Milton Keynes would jolly well have to live with congestion. He’s probably right, but one somehow expected a little more insight from a conference organised by the country’s transport intelligentsia. Is that really the best that £40 million a year and Europe’s most powerful computer can come up with? Two weeks later, the Mole joined a motley crowd of flotsam and jetsam from the bicycle world at 80 The Strand, the magisterial home of Penguin Books.The occasion was the rather grand launch of the Rough Guide to London, sponsored by Mayor Ken’s Transport for London.

For those unaware of how the other half live, the views from Penguin’s 10th floor balcony are most striking, although the book turns out to be something of a disappointment (see Review, page 11). No matter! For in a neat post-Congestion Charge twist, the BMW drivers grinding painfully along the Embankment below are effectively subsidising both the Rough Guide and the cocktails. Bottoms up!

Are electric micro-scooters legal?

aphid-spingo

The Aphid Spingo, good concept but is it legal?

I’m now worried by reports in the media that the courts are treating these machines as small motorcycles and putting points on the driving licenses of un-insured, un-taxed, un-helmeted users. Are they legal on the road, on the pavement – or as one shop told me – on cycle paths?”

David Johnson Truro, Cornwall

It is hardly surprising that there is such confusion, since the legal position certainly requires considerable clarification. Unfortunately, the current situation is far from satisfactory.

In a High Court case (CC N Yorks v Saddington, Oct 2000), a Go-Ped petrol-driven micro-scooter was found to come within the definition of a motor vehicle under Section 185 of the Road Traffic Act 1988.This means that their use is governed by the same legislation that applies to motorcycles and mopeds, since there is no criteria for minimum power or speed output.

Since then, the Vehicle Certification Agency, responsible for approving new vehicles, has considered that electric micro-scooters are also covered by the ruling, since they are no less ‘mechanically propelled vehicles intended or adapted for use on roads’.This was more recently confirmed in a subsequent High Court case (Letitia Water v DPP, July 2002) involving a City Bug electric model.

They are therefore deemed to be mopeds in the eyes of the law, since mopeds are the lowest powered two-wheel vehicles. However, this means they must meet the standards required for a moped to be used on the road.This will include the requirements for mirrors and lights, under the Road Vehicles (Construction and Use) Regulations 1986 and the Road Vehicles Lighting Regulations 1989. It is therefore illegal to ride a typical fun electric micro-scooter on the road.

It is also illegal to use them on cycle paths and pavements, where mopeds are not permitted.This leads to the ridiculous situation that the only legal place to ride an electric scooter is on private property.

“…riders potentially face a £1,000 fine and 6-8 points on their driving licence…”

However, any vehicle approved under European Community Whole Type Approval can be legally used on the roads.To date only one model, the German Charly MZ, has obtained EC approval, and this can, therefore, be legally registered as a moped, and used on the roads in the UK.

In fact, trendy urban types and youngsters alike are committing a whole raft of offences when you see them scooting around in a pair of shorts in the street. All the requirements for riding a moped must be met, including a licence, registration, insurance, a tax disc, and even an MOT after three years. A crash helmet must also be worn. Chris Eubank discovered this to his cost, when he was charged for scootering round Brighton without a helmet. He received a conditional discharge and had to pay £35 in costs.

Toy manufacturers have advertised the scooters as legal provided they are only ridden by children over 14, relying on electric bike legislation, but it is clear that the Department for Transport sees things differently.

Provisions in the Transport Act 1981 state that an electric bicycle avoids being classed as a motorcycle if it weighs less than 40kg, is fitted with pedals, has a maximum power output of 200 watts and cannot be propelled at more than 15 miles per hour. But in the City Bug case, the judge ruled that the scooter was not, ‘fitted with pedals by means of which it is capable of being propelled’, and therefore the Electrically Assisted Pedal Cycle Regulations 1983 would not apply.

This is clearly a grey area in the law, with many micro-scooter riders not unreasonably feeling that they are being arbitrarily restricted from engaging in harmless fun, or from adopting an environmentally-friendly transport solution.The Department for Transport has confirmed that there are no proposals to create a new category for scooters, or to adapt the electric cycle category to include them.

A further complication is that, despite defining micro-scooters as motor vehicles, the judges have so far refrained from actually categorising them, on the basis that this fell to the Department for Transport.This has made it impossible to obtain insurance since insurance companies are understandably reluctant to provide cover for vehicles which cannot comply with requirements.

As far as enforcement goes, this is obviously a matter for police forces to consider in the light of local circumstances, but warnings have been issued in a number of regions. While we often hear that ignorance of the law is no defence, it may be that in some cases ignorance really is bliss, since the police attitude has, by and large, been merely to warn riders genuinely unaware that their scooters are classified as mopeds.

But be warned! Driving without insurance is a Level Five offence, and riders potentially face a £1,000 fine and 6-8 points on their licence, if they have one. New legislation means that youngsters who have not yet qualified for a full driving licence will have these penalty points added to any future licence. And yes, police have confirmed that children will lose their licence when they’re old enough to hold one.

And that’s not all, people have been picked up for driving whilst disqualified and even drink driving, so riding one of the petrol-powered machines home from the pub could cost you your licence! The situation with electric scooters is more confused. According to The Royal Society for the Prevention of Accidents, at least one rider has been let off with a caution by the police, who concluded that the vehicle was covered by the same archaic catch-all law that applies to cyclists: ‘people who were very unsteady on pedal cycles, vehicles propelled by foot and steam-propelled vehicles’.The Department for Transport is unable to conclude definitely, since the issue has not yet been tested in the courts, but the view is that since the scooters can be classed as mopeds, it would be inconsistent if the same drink/drive legislation did not apply. So on top of everything else, make sure you stay off the liqueur chocolates before considering a scoot.

PowerShift grants – available for cars, but not bikes

DfT Grant NOT AVAILABLE!

Ever heard of PowerShift? For some reason, the authorities like to keep it a bit quiet – it’s actually a government-funded scheme to encourage the use of alternative fuelled road vehicles by refunding a sizeable chunk of the purchase cost. Electric, Compressed Natural Gas (NGV), Liquified Petroleum Gas (LPG), Hybrid Fuels… all offer better emissions than conventional petrol or diesel cars, but being rarer and more complex, tend to cost more, so PowerShift is a useful, if rather elaborate, scheme to get more owners on board and help to pull down purchase prices.Typical grants (12,000 have been distributed to date) are around £1,000 a time.

A few months ago, David Janner-Klausner of Transport 2000 asked us whether we had considered campaigning for electric bicycles to be included. Fully-powered electric motorbikes have now joined the scheme, but the Department for Transport refuses to consider electrically-assisted bicycles because:

…people who may have purchased normal bicycles would, if grants were available, choose an electric version instead.This would, of course, lead to a net increase in transport emission levels.

According to all the evidence we’ve seen, this is patent rubbish and typical of the official view that one is either a cyclist (and thus, irredeemably glued to two wheels) or a motorist – ie, a class of person who would never consider riding a two-wheeled machine.

On the contrary, there is a growing body of evidence that electric bicycles can kick- start a pronounced shift from car use. According to the Powabyke/Leeds University survey (see A to B 26), 26% of daily commuters, and 34% of those undertaking general A to B trips, would otherwise have used a car. Another important finding from this survey was that electric bikes get more use than conventional bikes, and tend to be used for more ‘serious’ – ie, non-leisure – journeys.

…it seems absurd that grants are available for… the Jaguar X Type and …

In any event, statistics can be misleading.The Henshaw family could be said to have transferred from bicycle to electric bicycle for some journeys, but these days – travelling 24 hilly miles each week towing a child trailer – we feel the need for some assistance. Had an electric bike not been available, we might well have been tempted to turn up at Alexander’s playgroup by car, just like everyone else. Electric bicycles are actually quite good at replacing the sort of short car journeys that everyone agrees should be shifted to other modes. Just the job for grant aid, surely?

Faced with this sort of evidence, the Energy Savings Trust – which runs PowerShift on behalf of the Department for Transport – caved in, but in a reply to David Janner-Klausner, made it clear that there would be no grants on electric bicycles. According to Matthew Robinson of the Energy Saving Trust:

I have looked into the matter further, and have established that our main funders (Department for Transport) decreed that only registered road vehicles are eligible for grant funding.Therefore vehicles such as fork-lift trucks, ones used at airports, and also electric push bikes are not eligible for funding.

Having read your arguments, I agree that purely on an emissions basis, if we were considering funding electric scooters then we should also consider funding electric push bikes. Unfortunately as I indicated above this would not be allowed under DfT rules.

It seems absurd that grants are only available for the 114 vehicles listed on the PowerShift register, particularly as 95 of them are using an alternative form of petroleum (LPG), and the list includes such world renowned gas guzzlers as the Jaguar X Type, BMW 5 Series and Jeep Grand Cherokee. Indeed, as LPG vehicles generally return fewer miles per gallon than their petrol-powered equivalents, we’d suggest that PowerShift is using tax-payer’s money to increase fossil fuel consumption. Only the DfT can change the rules… gentle pressure could make all the difference.

The Rough Guide to Cycling in London

From memory, the ‘Rough Guide’ travel-book series started life as a spin-off from a television programme of the same name a decade or so ago. Now some bright spark has hit on the idea of producing Rough Guides to cycling in capital cities, starting with London – the project getting off the ground with sponsorship from transport authority ‘Transport for London’. As with TfL’s award winning London Cycle Maps, the Guide is free, but on this occasion additional sponsorship has come from bicycle manufacturer Trek.

We’re not averse to sponsorship in principal, but we don’t think this formula works. It’s not that the Rough Guide dwells overly on Trek products and dealers, but there’s an insidious slant towards that sort of world.The result is a guide aimed at cycling newbies that puts loads of emphasis on MTBs, silly clothing, road bikes, and even cycle racing, but ignores hub gears, chain guards, and all the other essentials of urban commuting. How many new cycle commuters, for example, are interested in the pros and cons of leg-shaving in competition? Or Criterium Racing, whatever that might be? Under ‘Equipment’ we’re told to check reviews in Cycling Plus, What Mountain Bike? or Single Track. Are they serious? What about Velovision, or the CTC’s Cycle magazine, or even A to B? Magazines reviewing practical stuff for practical day-to-day commuters?

Strangely, for a book of this kind, electric bikes get half a page (with a few technical errors, unfortunately), but recumbents are dismissed, and folding bicycles – the key to city travel for a growing minority of cyclists – merit just a few lines. Similarly, cycling with children is virtually ignored, but in the Congestion Charge era, it’s a primary issue for parents looking for a non-motorised school-run alternative.

What we hoped for was the sort of insider information that have made previous Rough Guides such a success – where to find a bacon sarnie at 5am, or how best to navigate the capitals back streets.There is some route finding information in the Guide, but it’s a bit patchy – maps of key cycling cut-throughs would be better.

On the positive side, the first 20 pages on safety, the London Cycle Network and the financial advantages of cycling are useful stuff, as is the list of cycle shops in the capital, which alone make this a ‘must-carry’ guide. But much of the rest is either irrelevant or down-right off-putting to cycle returnees. Had we been asked (and we weren’t) we would have produced a very different Guide. Unfortunately, 200,000 have already been printed (although the cost is dwarfed by the £11 million being spent on cycling in the capital this year). Incidentally,TfL is asking for comments on its web site , so do make your views known.Yes, there are two gorgeous Treks to be won!

Old-tech Fights Back

Thanks for the review of LED lamps in A to B 33.The case design of the new Cateye lamps certainly appears to be a bit of a let down. Given the slightest opportunity, moisture will always creep into the electrics of poorly sealed cycle lamps and terminals will need occasional treatment with switch cleaner.

I use an Ever Ready Night Vision front lamp on my Brompton. I replaced the mounting bracket with a sawn-off section from the Ever Ready Night Rider bracket, enabling the lamp to be mounted near the centre of the handlebars, with a thick piece of rubber inside the clamp to avoid over-stressing the bars.

Rechargeable NiMH ‘C’ cells and a Reflectalite GH155 halogen bulb give excellent performance in a virtually waterproof lamp.The Night Vision was given a 5-star rating in issue 3 of The Folder – February 1994.

Up until about 18 months ago, Night Vision lamps were available in Woolworths, but Energizer UK may be able to advise if they are still available.

Jack Anderson
London

We did indeed give five stars to the Night Vision lamp. Ours, modified in much the same way as Jack’s (but permanently bolted in place of the front reflector, and fitted with a socket for recharging), is still in use nine years later – powerful, moisture-free and running with the same halogen bulb…The downside is a weight of 260g, plus an equally chunky bracket, but that’s still lighter than today’s Cateye EL300, so perhaps things haven’t advanced all that far. (Eds)

On the Right Wavelength

I’m a Canadian working on a PhD here in the UK, and was delighted to discover (in short order) the Brompton folding bike and your magazine! Regarding the discussion on lights in the current issue, it seems the human eye is sensitive to light which tends to the blue side of the spectrum (including ‘white’ LEDs) in such a way that, while the light from such devices is visible from a great distance, in many cases the lights actually do not provide great visibility.There is, of course, a great deal of dispute and debate on the topic, but a good source of information can be had at http://lighting.mbz.org/tech/bulbs/blue/bad/bad.html. A brief quote: ‘Blue is the shortest wavelength/highest frequency colour of visible light, and, as such, scatters the most readily.This is why the sky is blue rather than any other colour from the sun’s white output spectrum.’ And it explains why yellow light is so often chosen for use in foggy conditions, as it scatters less.While the better LEDs produce quite white light, this still scatters somewhat compared to the output of yellow incandescent bulbs.

Yum, yum

Since writing to you (Letters, A to B 34), I have found a better rain cover for the Cateye EL200. Ferrero Rocher hazelnut chocolates come in a clear plastic box measuring 14cm x 7.5cm x 7cm, which is ample. I clamped the lid to the bracket, fitted the lamp and put the box over the top, secured by two elastic bands – completely rain-proof, even in driving rain.

The Angle of Dangle

I bought Cateye LD600 and EL300 lights before your article arrived, and I have no complaints about them. I have used both in flashing mode and the Police have not shown any interest so far! But why sell lights that are not yet approved? Is Cateye planning to get these LED lights approved retrospectively? Or are they going to give us a trade-in on the approved lights?

The trouble with LEDs is that most have a 20 degree wide beam and the regulations call for 80 degree beam width inwards and outwards horizontally. So without a clever lens, an approved lamp would need a minimum of 8 LEDs, angled accordingly. Maybe the Cateye lenses are to spread, rather than concentrate the beams, which might explain why they are less satisfactory for lighting the road.

Incidentally, ‘white’ LEDs are really blue ones with white phosphor in front, reducing efficiency and increasing cost. As our eyes are more sensitive to the green/red end of the spectrum, perhaps LED lights should be comprised of a mixture of colours for maximum brightness and minimum cost/power consumption.

No Pump?

Your reviews of the Giant Lafree Twist in issues 27 and 31 convinced me that this was the electric bike to go for.The chap at the Solex Centre (King’s Road, London, for those interested) was extremely helpful and informative, allowing me several test rides on adjacent roads. Collecting a new machine a week later (and ordering a spare battery), I tried its performance on the 7-mile run home to north-west London – your review in issue 27 was right on the mark!

As I had dreaded a puncture, I’d taken with me a can of Finilec (similar to Tyreweld). Luckily, this wasn’t needed, but on arriving home it occurred to me that this expensive bike carried no essential extras: no puncture kit, no spanners, or Allen keys. Surely these could be included as goodwill? They were supplied with the Raleigh Boulevard Tourist (of whose weight and handling the Lafree now reminds me) that I purchased in 1965.

As I read Giant’s comprehensive owner’s manual, the light dawned: ‘Every 50 hours of riding: take your bike to the dealer for a check-up’. Are they serious? I know this is a power-assisted cycle, but is it really so precious? With anticipated daily commuting use, I’d be bringing it in every month! Anyway, Giant may be stingy, but I do like the Lafree Twist.

Chris Gielgud
London

With any bike, we’d suggest a thorough service after the first 50 hours (600 miles) or three months use, whichever comes first – a good shop should provide this as part of their after-sales back-up. At the first service, parts such as spokes, wheel bearings, brakes and chain will have ‘bedded down’ and may need adjustment and/or lubrication.Thereafter, if you make your own regular safety checks and adjustments, a bike may not need to see the inside of a shop for years. But for the non-mechanical, a professional check of brakes, tyres (including pressures) and bearings every 600 miles sounds a worthwhile investment.

Good point about tools and pumps.The Lafree rear wheel is quite difficult to remove, but that’s more to do with the Nexus 4-speed hub than the electric-assist. Don’t worry too much though – we’ve only had one puncture in 1,500 miles.

According to John Kawecki of Giant: ‘In these modern times there are more pumps sold by bike dealers than bikes themselves! We stopped supplying pumps with bikes many years ago as it became apparent that the customer wanted to choose a pump that suited their specific needs. If we supplied the pumps with the bikes then this would have to be reflected in the retail price of the bike and would not give a customer any choice. Sorry, but that’s the way of the modern cycling industry.’ (Eds)

My Car Costs Less!

I value all the technical information in A to B, particularly reports of tyre performance, electric bikes, batteries and real costs per mile. But I would appreciate a more detailed breakdown to show depreciation and maintenance costs.After all, there’s a lot of difference between 5p per mile and 10p per mile, which compares unfavourably with running my car (7.5p per mile, petrol only).And I suspect that a cycle-motor might cost less than 3p per mile.

The latter seems more promising than electric power for someone old and feeble like me for long distance touring, especially with a crank-mounted motor driving through a derailleur, giving the ability to climb anything.The thought of persuading the average B&B landlady that charging a battery overnight will not break the bank or catch fire while she sleeps is something I do not wish to tackle! In this context, fuel cells (using bottled gas) seem more promising, but I can’t see it happening before I ‘jump into the box’. Roll on the petrol-assisted semi-recumbent that does 200mpg.

Ian Taylor
Leominster, Herefordshire

Our electric bike running costs are calculated according to a simple fixed formula, assuming 2,500 miles per year, making no allowance for non-compulsory extras, such as insurance, 2p per mile for consumables such as tyres and chains, plus:

1. Purchase price fully depreciated over ten years. 2. Battery depreciated over 700 charge cycles (NiMH or NiCD) or 350 charge cycles (lead-acid) 3. Electricity consumed at 6p per kWh 4. Mileage per full charge based on the A to B test.

The resulting figure – generally 6p to 9p per mile – should really be compared to full motoring costs – currently averaging 30p-80p according to the Automobile Association. Against your 7.5p fuel cost, a typical electric bike costs around 0.1p per mile! As for cycle-motors, the AA puts the running cost of a moped (assuming 4,000 miles a year) at a scary 25p per mile.You could probably halve that, but clearly even a cycle-motor would cost more than an electric bicycle.

As for landladies, we’ve recharged electric bikes at a number of strange places, including a railway ticket office and an ice-cream kiosk – slightly bemused looks, but no problems. A payment of 5p would easily cover the fuel cost. (Eds)

Rightful Place…

I was delighted to see the letters by Michelle Whitworth and Patrick James (A to B 34), stressing the importance of cycling on the road with other vehicles. In North America, we too have those with a fantasy of a segregated system for cycles, free from competition with motor vehicles.The more that we can persuade people to get out of their cars and walk, cycle or take public transport the better, but realistically, we’ll be sharing the road with motor vehicles for the indefinite future.

The existing road system was designed to make it efficient to get from A to B, with an almost infinite number of origins and destinations. As cyclists, the less distance we have to go out of our way between A and B, the better.This usually means taking the existing road.

I’m grateful for the pioneering work of John Forester, in his Effective Cycling (first edition 1975), for outlining that cyclists fare best if they behave like a car, obeying traffic rules, signalling their intentions and taking their rightful place on the road. I rode for nearly fifty years before encountering this material, and it has really focused my attention on the hazards and how to avoid them. For example, most urban accidents occur at intersections, not from being hit from behind. Special paths or lanes for cyclists just compound the dangers of this mix. Forester’s book is now published by MIT Press.

The 1993 reprint of ‘Effective Cycling’ is available in the UK – about £20 for the paperback (Eds).

D.I.Y. Cycle Routes

Urban cycling without recourse to Sustrans paths (Letters, A to B 34) is easier than you might think. Simply note your start and finish points on a street map and draw a line between the two.You can then choose a route linking up all the side streets running parallel to main roads – these are surfaced, reasonably direct, lit, safe, virtually traffic-free and don’t usually involve gyratories and junctions from hell.

As for low-mounted lights, I was very nearly flattened by a lady motorist who didn’t see my Brompton front light on an unlit street, so it’s now at handlebar height, without folding problems. I also use a secondary rear light at saddle height.

Charlie Hall
Whitley Bay,Tyne & Wear

In Sustrans’ defence, the organisation has always recommended the Dutch cycle path model (see page 36), where road traffic usually gives way to cyclists. It is not Sustrans’ fault that UK local authorities and the DfT have generally refused to adopt this approach, leaving most urban cycle paths difficult and dangerous to use. As for lights, we would suggest keeping the battery/dynamo lights where they are, but fitting secondary high-mounted LEDs front and rear.The LEDs illuminate signs and alert motorists, while the low-mounted conventional battery or dynamo light provides warning of pot-holes and other nasties. (Eds)

Load Carriers Rumble On

In support of Professor Pivot (A to B 34, page 14), I tried the Cargo Bike when on holiday with our two children of 17 months and nearly five.There is plenty of room for them plus luggage, and in addition to the features mentioned by Steven Brandist (Letters, A to B 34), there is also a frame lock.

On a flat clear road with a following wind, it performs well. But when you start to climb, the handlebars flex and you soon run out of gears, so you resort to pushing.There is little point in fitting lower gears because at low speeds handling becomes challenging.The brakes are weak too, so emergency stops and steep descents are a bit risky.

Catherine Girvan
Worcester

And From The Trade…

In reply to the debate over child and/or load-carriers, by far the most important thing in parents’ minds when purchasing a vehicle to carry children is safety. Front-loading tricycles, such as the Christiania, offer a number of advantages:They are more stable than two- wheeled vehicles; they have a sturdy box that protects its passengers; they have a more assertive presence on the road; the children are always in view of the rider; it is safe to carry babies in their cots. Note too that the Christiania Light has 24-inch wheels all round.

Sleeping Centurions

Richard Dunn has missed out on a couple of points (Letters, A to B 34). First, unlike our ‘free’ press, A to B’s policy of not being pro-car isn’t anti-car. If I were looking to buy a financial product, my advisers would have to declare an interest – our national press claims to be unbiased, but the contrary is often the case.

Secondly, while ancient Rome had traffic problems, it also had traffic laws which make Ken Livingston’s £5 charge seem very reasonable.You could only use two-wheeled vehicles at certain times, and it wasn’t advisable to charge at a pedestrian crossing, as they were basically a set of stepping stones across the street. Early traffic-calming perhaps – drive carefully or wreck your chariot! An idea that might be worth copying.

Rules Of The Road!

I commute to work by bike/train, and every day I see the same thing – cyclists flagrantly breaking the law in ways they would never dream if they were driving a car. And this is everywhere, not just London: running red lights (the favourite), going the wrong way on one-way streets, cycling on pavements, cycling at night without lights, ignoring pedestrian crossings when in use… the list goes on.These ignoramuses don’t seem to realise that when a cyclist gets away with breaking the road traffic laws, the motorists who witness this get p***ed off.The more annoyed they get, the less respect they show to all cyclists. I’m not saying motorists are innocent in this, but I can understand their irritation with cyclists.

Jason Collins-Webb, Reading

Load of Rubbish

I think the principle of electric vehicles is great, it’s just that I haven’t had any luck. I bought a Citybug e2 scooter, and the throttle/drive mechanism malfunctioned twice after only a few miles. I also bought the Bikit electric-assist kit, unfortunately before reading your review.The kit won’t install on either of my bicycles because the frame tubes are too thick and I can’t get the proper clearance between the pedal crank and sensor.

Since I don’t live in a hilly area, and I’m not faced with the prospect of carting heavy loads, I don’t really need electric-assist, but if I do want to have an electric bike in the future, should I invest in something like a Giant LaFree or Heinzmann?

Steve Wirzylo,Toledo, USA

We don’t think luck comes into it! Cheaper powered vehicles are designed for occasional leisure use. If you want something that will give good service, it’s best to choose a proper bicycle and a reputable drive system.The Lafree and Heinzmann are probably the best around at present. (Eds)

Nuts in May

Your picture of the nudists and a Brompton in A to B 31 brought to mind a claim made to me some time ago by my friend Julian of ‘Bona Bicycles’, Balham. He swears that Andrew Ritchie originally intended to call his splendid machine the Hampton – and was only dissuaded by a colleague observing that the folding process might entail some small risk of getting his Hampton caught.

Tyre Pressure – Real-world & Witch-craft

“It’s nice to see Professor Pivot using ‘real world’ testing for tyre comparisons, and some believable results. A couple of observations though – we tend to quote pressures in pounds per square inch (p.s.i.), but only notice the ‘p’ and ignore the ‘s.i’. For the same indicated pressure, a larger tyre will have more pressure inside and give a harder ride. In the same way, the smaller cross-section Stelvio will have a smaller outside diameter.When I tested 700C against 27″ of the same tyre, the difference was clear.

Finally, what’s all this nonsense about ‘faster up hill’? When climbing hills, the power input is as variable as the descending force is consistent – please don’t mix science with witchcraft!”

Mike Burrows
Norwich

Professor Pivot replies: Narrow section tyres do require higher pressure, and the effect can be quite marked. For example, the cross-sectional diameter of the Brompton 37-349mm tyre is 34mm and the Stelvio 28-349mm tyre is 30mm. If my limited mathematics is correct, the larger tyre has a cross-sectional area 28% larger, so where 80psi might be adequate in the large tyre, it seems reasonable to assume that a little over 100psi would be required in the smaller example.Verification of the theory – and an entertaining parlour game, no doubt – can be found by inflating a bicycle inner tube and a heavy goods vehicle inner tube to the same pressure and sitting on them…

But will the narrow tyre at 100psi react in exactly the same way as the wider example at 80psi? I suspect that if the two tyres strike the same bump under the same load, the cross-sectional area will be temporarily reduced by the same percentage in each case – let us say 20%. Once again, I must apologise if my thesis is running ahead of my mathematics, but I believe a reduction of 20% in the cross-sectional area for the big tyre would result in a deflection of 3.48mm, but for the small tyre the deflection will be only 3.08mm? This suggests that the smaller tyre might transmit smaller ‘choppier’ deflections to the bike – a harsher vibration, in other words.This might increase rolling resistance, but would also tend to reduce energy-wasting bounce when pedalling hard.

A good rule of thumb, whatever the bike, rider, road and tyre combination, is to inflate the tyres (individually, to avoid confusion) until the ride becomes harsh, then set the pressure a little below this point.These personal figures should give a reasonable ride/handling/rolling compromise specific to you and your bike.

Mike also makes an excellent point about keeping ‘seat of the pants’ observations well separated from repeatable and reasonably scientific results such as roll-down tests. But observations – however implausible they might seem at the time – do occasionally lead to a new avenue of enquiry, so they’re worth making, with the proviso that they are treated with the necessary caution.

When testing the Stelvio and the Brompton tyre back-to-back on repeated roll-down tests, I obviously rode back up the hill a number of times. On these return runs, the Stelvio tyres certainly seemed to make smoother progress, allowing the rider to hold on to a higher gear. But with no means of measuring the power input from the rider, I fear this casual observation must remain unproven!

Reamers & Pins

“Recently, whilst replacing my 7-year-old Brompton’s rear mudguard, I noticed play in the rear triangle pivot. Some on-line research suggested that the pin retaining screws cannot readily be unscrewed and would have to be drilled out. A replacement pin is available as part of a kit, but there were ominous references to expensive tooling to deal with the frame bushes. I duly drilled out the screw heads and pushed out the steel pin, which indeed showed some wear at the ends where it runs in the bushes.

To my surprise, the bushes appeared to be only slightly worn and I was able to make up a replacement pin from some over-size silver steel rod.This is now installed and the play has disappeared so I did not need to find a dealer to do the repair.

Assuming the pivot does not seize through lack of lubrication, I doubt if a degree of wear matters much, except when it causes those not used to the Brompton’s rear end bobbing to ask if something is wrong!

George Winspur

Professor Pivot replies: Your observations are entirely correct, George. Brompton does insist that the new bushes be reamed to size using a precise and rather specialist tool. Only a limited number of UK dealers, and distributors in Spain, Germany and the USA are equipped with these tools, so – besides the Brentford factory – these are the only outlets able to undertake a full rebuild.

However, the Brompton functions well with a surprising amount of wear.This can be measured by sitting the bike in the part-folded position and rocking the back of the rear wheel. From my experience, 5mm of play has little or no effect on handling. If modest play has developed, the life of the hinge can be extended by adding a few drops of heavy oil at regular intervals, particularly after riding in the wet.There’s no need to do anything else until play reaches about 10mm, which should take 10,000 miles, or even more. By this time, the bike may feel a bit nervous, particularly on fast reverse curves.

A complete rebuild will probably be needed, but as you also correctly observe, most wear occurs on the pin, so it is often permissible to replace the pin alone. For those with an engineering background, the complete kit (including pin, replacement screws and even a suitable drill should the old screws be seized) costs £11.84 from good Brompton dealers, or the factory.When fitting the pin, make sure the bushes are well coated with grease, but take care to keep grease clear of the threads, both on the screws and the inside of the pin.The screws must be locked in place with a suitable thread sealant – if left dry, they can unwind in use, and ultimately cause the pivot to collapse.

For machines ridden in extreme conditions, the life of the pin can be extended by fitting a grease point, which not only allows grease into the heart of the assembly, but expels grit or water that may have worked its way in.The expert at this treatment is Steve Parry – tel: 01934 516158 or email: spbicycles@aol.com

Chariot Cougar 1

chariot-cougar-1Hardly a day goes by when we don’t grumble about the lack of bicycle trailer awareness in the UK.The Dutch and Germans love ‘em, or so we’re told. On the Continent (and, to be fair, in some more enlightened pockets here), the School Run no longer means heaving a tonne of Volvo into a queue of other Volvos, to drop your tiny charges in the ‘Strictly No Parking’ zone outside the school gates, but a quick and hopefully stress-free cycle ride.

This sort of journey – generally a couple of miles or less – is a perfect candidate for cycling. A child seat is great in the summer, but for secure, all-weather transport, a trailer makes a better option. Hence our frustration – trailers are cheap to buy (bought a new Volvo lately?), economical to run (just work off that breakfast) and practical (no parking restrictions and very little queuing).

We’ve had experience with two classics in the trailer field – the Winchester (now manufactured by Kool-stop) and the Burley Solo, the latter fully reviewed in August 1999 (A to B 13). In the same test, we tried the Chariot Cheetah, but found it a bit leisure- orientated for our tastes – more jogger than cycle trailer.We’ve revisited the Chariot stable to see what’s changed and stage a rematch with our elderly, but much loved Burley.

Chariot

chariot-cougar-2By the time a Chariot trailer arrives in your local cycle shop, it has done a fair old mileage.The trailers are manufactured in Canada, then shipped to Germany for distribution by Zwei plus Zwei. In the UK, trailers were formerly sold through Two plus Two, the trailer specialists in Lewes, but new distributor Amba is aiming to take on board a number of regional shops too. By and large, that means the sort of outlets that advertise regularly in A to B.

Back in 1999, Chariot produced only four designs, but by 2003, the Cheetah had been joined by a bewildering range of alternatives.We’ll try to keep things simple: there are three ranges – city, touring and sport. For practical, everyday commuting, the city trailers are the best choice. There’s a basic Comfort model at £360, plus the Captain at £430, with ‘proper’ (as opposed to moulded plastic) spoked wheels and polymer-bungee suspension. These chunky, practical load-carriers include a cavernous boot for serious shopping and a waterproof polyethylene floor-pan that extends right over the wheels to cut spray, a big problem on child trailers.Take our word for it – if you intend to use a trailer on a regular basis, in all weathers, most other designs will stay soggy inside and out for much of the winter.The Comfort and Captain are uniquely sensible and practical in this respect, but they’re a little wide (102cm) and heavy (claimed 13.7kg) for some purposes.These big trailers won’t negotiate most supermarket aisles, and bundling one into a small shed at the end of the day – folded or not – would be a frustrating task.

The touring trailers (base model Cabriolet and deluxe Corsaire – priced as above) are typical bike trailers, more suited to fine-weather commuting and/or weekend leisure use. As with the city trailers, the deluxe job has spoked wheels and suspension. Chariot also produce the Chauffeur at £400, an older design, now made exclusively for Zwei plus Zwei, so one must assume, a big hit on the Continent.

Finally, we have the sports models; the Cheetah at £360 – broadly as tested last time – and its deluxe cousin, the Cougar, at £430, with the now familiar ‘proper’ wheels and an unusual leaf-spring suspension offering longer travel and better response than the bungee type. Both of the sports jobs also come in single-seater versions, priced at £330 and £400 respectively.We chose the Cougar1. It sounds obvious, but if you’re carrying only one child, it’s better to go for a single-seater.They’re lighter, more manoeuvrable – both on the road, in the supermarket, and in the shed – and they can be shoe-horned onto public transport.That’s the practical reason for our choice.The other is that the Cougar1 looks remarkably sexy as trailers go – a mini Formula One car in red, grey and silver livery, with tinted windows and that adjustable suspension.

The Cougar

…lightly loaded child trailers ride best with almost zero tyre pressure…

Where the Winchester and Burley ooze practicality from every pore, the Cougar is about as impractical as cycle accessories get. Despite a wheelbase of 65cm, in true Formula One style, the interior measures just 30cm across, with 60cm headroom, and 50cm legroom.That’s barely large enough for our just-turned-four year old, let alone a modest Thomas-the-tank-engine lunch box, and you can forget shopping on the way home. If luggage won’t fit in the rear bag, slung kangaroo pouch style behind the trailer (with a minuscule weight limit of 1kg), you’ve had it. Chariot also produces a luggage rack or ‘lightweight extra luggage’, which perches ludicrously on the roof, so the lightweight luggage risks blowing away, or being eaten by a motorcycle courier at the traffic lights. It’s all nonsense on a bicycle trailer, of course, but makes more sense when you realise that the Cougar is primarily a ‘stroller’ (for which a handy conversion kit is available).This also explains the effective rear parking brake.

To be fair, this is the single-seat version.The Cougar2 is only 11cm wider, but offers nearly twice as much width inside – 59cm. That’s reasonably generous for two and ample for one, provided you can live with the extra weight and bulk.

chariot-cougar-suspension

The Cheetah suspension has two leaf springs - the clamp can be slid along to adjust the spring rate

OK, we’ve settled that shopping might be a problem, but how does the Cougar perform on the School Run? Image- wise, it’s a striking success. Kids really do appreciate the tinted windows and racy lines, and mums immune to less- flamboyant trailers, squeak with delight.

Alexander particularly admires the ‘s’pension’. One thing we’ve learnt, is that lightly-loaded child carriers ride best with almost zero tyre pressure, or the poor mites will be shaken to bits. Even then, trailers have a tendency to crash into pot-holes – it’s worth remembering that the occupant(s) can’t see what’s coming and brace themselves.

The Cougar gets around the problem with a pair of leaf springs each side, the two leaves being tied together by an adjustable clamp that can be moved to alter the spring rate.That’s a great feature on a machine designed for children from 0 to 5 years old, but we’re not convinced the softest setting would react properly under the weight of a baby – we ignored the weight chart and chose this setting for our 18kg boy.Those Canadian roads must be mighty smooth.

In normal use, the suspension doesn’t react, because the springs are pre-loaded against a polymer stop. But hit a bump and the leaves overcome the pre-load, allowing the wheel/s to rise up over the bump to a maximum of about 35mm. It’s much more effective than the squidgy tyre option, giving greater travel and better control.

Why has suspension taken so long to arrive? Presumably the engineers haven’t been listening to the legitimate complaints of small children. One or two other designs now offer suspension, but generally a less compliant polymer system, as on the Cougar’s larger cousins, the two seater Captain and Corsaire. In our opinion, you’re better off with low tyre pressures than this sort of thing, which is not intended to do more than round the tops off bumps, and (according to Chariot) only work satisfactorily with a load in excess of 25kg anyway.

According to Alexander – who’s well placed to voice an opinion – the Cougar leaf springs, hammock seat and general cosy fit, combine to provide a jolt-free ride, so full marks on that score. Incidentally, although the Cheetah looks low and wide, its wheel track is less than three times its seat height, whereas the much lower Burley Solo and two-seater Winchester are around 4.7.This makes the Cheetah less stable in theory, but we’re not suggesting it’s likely to turn over – child trailers have a massive reserve of safety.

All-Weather?

chariot-cougar-wheel-axle

Wheels are secured by clevis axles - push a button and the wheel pops off

The Cougar weather-proofing is about as complex as they get, offering no fewer than four individual layers. Basic protection is provided by a full-length mesh fly-screen, which should stop small stones thrown up by the towing bike.To add a bit of sun screening, a sun-roof with nifty tinted visor can be rolled out under the mesh, and in cold weather, a full-length polyurethane cover provides wind-proofing and protection against flying horse pooh and mud, although Chariot emphasises that this option is not rain proof (and it definitely isn’t). All Chariot trailers can be fitted with full rain covers, but they’re a £20+ option, and you need to remember to buy one and carry it when the weather looks dodgy. All the same – from our experience of leaky roofs and screens (they all leak in monsoon conditions) a well-sealed separate rain cover is probably a good idea.

Folding

chariot-cougar-folded

Not the smallest package, but quite neat - note the tight fit for the wheels

Trailers have come a long way. Our Burley ‘dismantles’ rather than folding, and the wheels are bolted in place, so you need a spanner and can expect to get grubby.The Winchester folds flat in a few seconds, but the wheels are held by locking-pins, which can make removal a fiddly, oily operation.

To fold a Chariot trailer, you simply pull out a pair of safety pins and push two levers forward, allowing the whole trailer to hinge downwards with a scissor action.The tow hitch pops out after releasing a pin, and depressing a lock button.The wheels are even easier, being secured by ‘clevis axles’ featuring a couple of raised ball bearings that engage with a groove in the frame, holding the wheel in place. Press a rubber cap in the centre of the wheel and the assembly pops off.

With practice, the process takes about 20 seconds, leaving a package weighing 10.8kg (Chariot claim 9.7kg).Two provisos: On the single seater the wheels won’t quite fit inside unless the tyres are partially deflated, which would add all sorts of annoyance at journey’s end.And we’d be slightly nervous about the security of the clevis axles after years of abuse.That aside, it’s probably the quickest and easiest folding system around.

For the Cougar1, the result of all this activity is a folded package of 105cm long x 59cm wide x 27cm tall.Volume is 167 litres or 6 cubic feet – slightly smaller than the Cheetah we tested in 1999, mainly because the wheels can now be stowed inside (although we might have missed this last time). Back then, we thought the trailer was unsuitable for carriage by train. Thanks to the reduced folding time and smaller package, we’d say it’s much better today, although the same cannot be said for the two-seater models.

Hitches & Accessories

chariot-cougar-tow-bracket

The axle tow bracket mounted to a hub-gear bicycle. Note the over-size allen-key nut - part of our Burley hitch!

Chariot produces three hitches, which are all interchangeable on any of their trailers. Cheapest is the universal tow arm – a ball-joint and fairly sophisticated frame-tube clamp at £30. The disadvantage, of course, is that the clamp must be positioned and tensioned every time the trailer is used. OK for leisure rides, but not feasible on a daily basis, or secure enough when it’s wet or icy.

chariot-cougar-baby-seat

Chariot’s baby seat can be fitted to any trailer in the range

The standard hitch is the ‘axle tow arm’ – a simple alloy bracket secured to the rear axle of the bike with the standard quick- release or hub nut.The tow bar ends in a plastic ball once again, which slides backwards into the bracket, and is secured by a pin.This design doesn’t quite allow for full rotation (the ball could be strained if the bike falls over, for example), but it’s quick and easy to use on a daily basis. Both the above include safety straps looped around the bicycle frame – the straps, incidentally, being a little shorter than we would like.

chariot-cougar-stroller-kit

The stroller kit - neater and lighter than most. Chariot also produce a buggy kit and that all-important ski kit

Top of the range is the German- made Weber hitch, costing £50.The bicycle end if this complex device incorporates a basic stand, a clever universal joint and the trailer socket, the assembly being permanently fixed to the bicycle frame. At the trailer end, the tow bar terminates in a locking device that engages the bicycle with a satisfying click and can even be locked on or off with a key to prevent theft.The makers (and presumably the stringent German safety authorities) are so confident in the system that there is no safety strap. Once it’s all fitted and working, hitching up and unhitching is quick, easy and secure.

The list of options includes stroller, hiker and buggy kits, plus – most spectacularly – a £150 ski kit for the Cougar or Cheetah. If you’re just starting out with trailers (and children), you might find the baby seat (up to 10 months) or baby support (10 – 20 months) more useful. For cold weather, there are two foot-warmer options, plus a wind-proof and/or chill-proof Polartech sleeping bag sort of thing. Serious stuff, and all beautifully made.

Conclusion

At £330 to £430, Chariot trailers look expensive against supermarket jobs and pile-’em-high Chinese horrors selling for £100 or less. But the quality of the range speaks for itself, and most people who know something about trailers agree they’re superb machines.

Better than the Burley? Tricky one that. Alexander prefers the Burley, which is more practical, but less exciting; lighter, but slower to fold; and about the same price. In the end, you’ll probably want to look at both ranges before making up your mind.

Shadow Bicycle Alarm

shadow-bicycle-alarmSecurity is a headache for cyclists. All too frequently, you return to find either an empty space or a pile of wreckage where your pride and joy had been sitting only minutes before. A major transformation in the attitudes and behaviour of society is the only real answer, so we might have to make do with protection for a wee bit longer.

The Shadow alarm is produced by Evnatech, a small company in Wales, and it’s a brave attempt to solve the problem by making a bicycle too hot to touch, hopefully eliminating vandalism as well as theft. Once upon a time, alarms were relatively hefty devices, but the Shadow is a small cylindrical tube that you shove in the handlebar and forget.To turn the alarm on and off, you insert a small ‘key’ (actually a coded jack-plug) through a small hole in the handlebar grip.This produces a variety of interesting noises – removing it again results in silence if the alarm is deactivated, or a sort of ‘grmmph’ when it’s ready for business. From now on, any movement of the bike will result in a piercing warble, loud enough to give even the most persistent thief a collywobble.

Of course, alarms are not the be-all and end-all of security, as any house-owner or motorist will testify.The exponential growth of the alarm industry has resulted in a world where we no longer take any notice, and false alarms can cause a great deal of annoyance to innocent passers-by. For example, it would be nice to alarm a folding bike on the train, giving protection should someone try to walk off with it. But the Shadow is too sensitive for that sort of environment – it would probably go off if an innocent cyclist tried locking their bike to the same rack too.

That aside, the Shadow is an effective little device. It’s small enough and light enough (40g, or 10g lighter than claimed) to fit and forget, and a welcome deterrent against theft, vandalism or plain fiddling, on those occasions when you pop into a cafe for a cup of tea and a cream scone. It’s also a practical overnight alarm too.With the alarmed bike parked in a garden shed or garage, you’ve effectively alarmed the whole premises.

The bad news (there had to be some, didn’t there?) is that the Shadow only fits tubes with an inside diameter of 17-19mm.Tackling the random sample of bicycles in our workshop, it will fit older Brompton handlebars with an outside diameter of 23.5mm and Pashley Micros, but it won’t fit post-1995 Bromptons, our Giant Lafree, or the new Dahon Vitesse. If in doubt, it would be wise to get advice – the Shadow will fit most mountain bikes or hybrids, provided they have empty, straight handlebars.

Evnatech has been listening to these grumbles, and is working on a version for drop – and other curly – handlebars, including those of smaller diameter, which should deal with our unusual collection. Production is expected to commence in a month or two.

brompton-luggage-for-all-2

Brompton luggage for all!

brompton-luggage-for-allEven those with no love for small wheels have to grudgingly admit that the Brompton front carrier system is superb, and arguably better than the universal KlickFix system. The Brompton design is based on a frame- mounted carrier block, and a variety of panniers, which can carry big loads and pop on and off the bike very easily.

Once you’ve got used to this sort of convenience, traditional panniers look positively Stone Age, and a frequent request from those owning both a Brompton, and a fleet of other bikes, is whether the carrier block can be fitted to other machines.The short answer is yes, but it’s not easy…

On the Brompton, a metal plate is brazed to the frame, and the carrier-block bolted to this plate. If you’re building a new machine, or completely rebuilding an old one, Brompton can supply the plate and you can do exactly the same. But before waving an oxyacetelene torch at your bicycle, check that the luggage won’t foul the handlebars or other parts, as the Brompton handlebars are unusually tall… A little more clearance can be found by grinding the carrier block base so as to angle the block and pannier forward, away from the ‘bars.

If brazing is not an option, the carrier-block can sometimes be bolted in place. Remove the forks, drill through the head tube and bolt the block in place from the inside (the bolt heads may need to be ground down to clear the fork tube). Obviously, all components must be of the best quality, as the Brompton carrier-block is designed for loads of up to 10kg (all on a pair of small 5mm bolts!).We’ve carried twice this weight, but it makes sense to play safe with conversions…

As several readers have noticed, our Giant Lafree takes Brompton luggage. Fitting the pannier to the front proved impractical, but there was room on the Lafree’s rear rack, so we decided to fit the pannier on the left side at the rear.

brompton-luggage-for-all-2

The finished carrier. Note the large self-tapping screw threaded into the extrusion

Modern alloy rack stays are light and strong, but need to be treated with care (we sometimes carry a child seat on the rack, for example), so it’s better not to weld, deform, or drill them.We decided to make a simple bracket using a length of aluminium extrusion from an old television stand. This useful material is strong, pre-drilled down the middle to accept self-tapping screws or small bolts, and can be easily cut and shaped.This was particularly important in our case, because the extrusion needed to fit snugly between two alloy rack tubes.

Once the extrusion was a snug fit, we drilled a small mounting hole in each of the stays and fitted the self- tapping screws that once held the TV stand together…With the Brompton carrier-block ground flat on its rear curved  face, we were able to bolt it straight onto this  new mounting plate.  In use, we found the screws needed tightening a couple of times as the parts bedded in, so we filled the mounting plate with builders’ ‘expanding foam’, which hardens to a rubbery consistency, helping to spread the considerable loads that are being transferred from the pannier into the rack frame. The rack-mounted Brompton pannier has been very successful.We wouldn’t want to overload it, but the ability to swap luggage between any of our bikes (the Fold-it has a Brompton block too) is a great advantage. If you don’t feel confident to undertake this sort of job, any good cycle engineer should be able to produce something similar.Those with knowledge of Brompton carrier-block conversions include Cyclecare (tel: 0207 460 0495) and Kinetics (tel: 0141 942 2552).The mounting plate is available direct from Brompton (tel: 0208 232 8484), and carrier-blocks, panniers and other parts should be stocked by Brompton dealers (see www.bromptonbicycle.co.uk for a list)
