Unlike certain Green publications, New Consumer strikes a nice balance between consumerism and hair-shirt utopianism. Its printed on a matt-finish recycled paper, which sounds a bit dour, but the content is lively and the cover stories eye-catching and (dare we say it?) sexy. In March, for example, the magazine features fair trade clothing – once the preserve of scratchy-looking T- shirts, but now firmly entrenched at the fashion end of the market.
This all sounds suspiciously New Age and touchy-feely, but New Consumer is a practical and informative guide to fair trade products. With global trade increasingly dominated by greedy mega-corporations and unscrupulous trading cartels, its all too easy for the little folk to get squeezed out, leaving millions reliant on hand-outs, when all they really want to do is sell their bananas, tea or cocoa at a fair price.
Fair trade – spear-headed in the UK by the excellent Co-operative movement (the Co-op sponsors New Consumer) – is a neat way of circumventing the inequities of the global trading system, by working closely with producers and guaranteeing to pay them a fair price for their labour.You might think that this would make the products expensive, but because there are no middle men and corrupt officials taking a cut, thats not necessarily so. A quick search around our local Co-op reveals that fair trade products are broadly mid-range (and we can vouch that the chocs and Clipper tea are jolly good). Until recently, fair trade meant coffee, chocolate and little else, but the list is expanding rapidly, and – watch out – supermarket giant Tesco is beginning to take an interest, which gives you some idea of the way the wind is blowing.

Long ago, we built a lightweight Brompton, wrote up the saga in A to B 7, and went on to sell hundreds of extra magazines. We’re still producing photocopies today, which told us something, and maybe Brompton took notice too – there seemed to be interest in reducing the weight of the bike.With hindsight, we did rather well; our fully-equipped 3-speed Brompton tipping the scales at a shade under 10.5kg (23lb), including a front luggage block, mudguards, rear LED and even toe- clips.
Almost seven years later, Brompton has produced its own lightweight machine. It’s more expensive, and a 2- speed rather than a 3-, but the new S2L-X weighs only 9.7kg (21lb), making it one of the lightest folding bikes in current production, and certainly the lightest Brompton ever produced. If you find the Brompton heavy to carry, this may be the machine for you, but are you willing to pay £965? For Brompton, we doubt whether the opinions of creaky old fogies like us are of any importance, because this chic, hi-tech bike will be aimed at younger people (all the brochure models are under 30), with particular emphasis on young women.
…Brompton needs to attract the sort of people who wouldn’t be seen dead on a Brompton…
Will this lighter, but very much more expensive, bike really appeal to a whole new generation of 20-something professionals? We think Brompton is right to aim for this group, because – if you haven’t noticed – the demographic of cyclists is becoming more and more decrepit. If the folding bike market is to survive and grow, Brompton needs to attract the sort of people who wouldn’t be seen dead on a Brompton. It’s a tall order.
The S2L-X
Narrower, lighter Stelvio tyres
To the untutored eye, the S2L-X is a conventional folding bike.The only unusual bits are straight handlebars, and an odd paint job: Flamingo Pink according to Brompton, but anyone with experience of school dinners in the 1960s and 70s will recognise ‘school blancmange’. Look more closely, and there are other differences: the decal is a designer job, the saddle is sportier, the front forks and rear frame are made of titanium and the bike has narrow Schwalbe Stelvio tyres and a 2-speed derailleur. Look very closely indeed, and you may spot the titanium mudguard stays, new brake levers and alloy headset.There’s lots of technology here, but it only really becomes apparent when you pick the bike up, because it weighs 9.7kg, against 11-12.6kg for the normal bikes.
…other traffic will already be braking, putting the nifty shifter back up front…
Titanium front forks
Jump on, and the feel low and very rigid.The lack of gears doesn’t seem to be a hindrance, because what the bike loses in ratios, it gains in rigidity – the straight bars being much less flexible than the old ‘violin case’ design. By fitting the standard 2-speed derailleur with 12- and 16-tooth sprockets (in place of 13- and 15- tooth), Brompton has given the S2L two well chosen ratios of 56″ and 74″, which one might equate as ‘starting gear’ and ‘riding gear’.With gears like these, you won’t climb any mega-gradients or spin along at 20mph, but the bike copes with hills of up to 10% and – thanks to the lighter rotating bits and single slick gear change – it accelerates well, easily outpacing more cumbersome bikes up to 14mph.Thereafter, the lack of gears begins to tell, but in most city conditions, the other traffic will already be braking for the next traffic lights, putting the nippy shifter back up front. Remember too, that a simple 2-speed derailleur is more efficient than a hub gear.The result is a machine that really demands to be ridden hard and responds well.
…the derailleur slips easily and slickly between the two gears…
We were a little disappointed with the Schwalbe Stelvio tyres when they came out – not because they were slower or heavier than the cutting edge products, but because they were less sturdy without being notably faster or lighter.We questioned whether a weaker tyre was worth fitting for such a small gain. Brompton has clearly decided that it is, claiming a weight saving of 140g (presumably with lighter Schwalbe tubes as well) over the standard Brompton tyres.We didn’t find quite such a big differential, but we’d agree that the Stelvio is the lightest tyre available, albeit by a narrow margin. Brompton makes two cautionary points: avoid using a bottle dynamo, which is liable to shred the sidewalls, and keep the tyre pressures above 85psi or heavier riders will risk ‘pinch punctures’. Otherwise, these tyres are fast, reasonably comfortable (only fatties will need the full 120psi), and light. Aided by the low riding position, 80/100psi in the tyres, and a nice warm spring day, we recorded an excellent 15.4mph roll down speed – one of the fastest runs we’ve seen with 16-inch tyres.We only had time for a few runs, so this figure won’t be very precise, but it’s worth bearing in mind that all three of the folding bikes reviewed in this issue were tested together, so comparisons are certainly valid.
2-speed derailleur. Note the standard Brompton tensioner arm and new free hub
The derailleur slips easily and slickly between the two gears, which are further apart than the standard Brompton 6-speed, but closer – and thus smoother changing – than the Highpath Engineering conversion. Incidentally, anyone intending to take an angle grinder to their new titanium frame in order to fit the Highpath wide ratio cogs will be wasting their time.The 2-speed has a special 9-splined hub which is incompatible with anything else.That’s a shame, because we think some users would prefer a slightly lower first gear, even at the expense of a bigger jump between the two ratios.
Braking feels odd, despite the bike being fitted with familiar dual-pivot callipers.The new Brompton levers obviously impart a different feel, as do the Jagwire cables.We’ve found these super-slick elsewhere, but the cables seemed stretched on this bike, giving a sticky response, particularly at the rear. There’s no fundamental reason why such good cables should bind, so we assume everything will be sorted for production.
Folding, Adjustment & Accessories
Apart from the handlebars, the machine looks fairly conventional
We won’t say much about folding, because the procedure is the same as a traditional Brompton, but once you’ve folded it, 9.7kg is obviously easier to carry than 12kg. Most people find a standard Brompton hard on the arms when crossing a railway bridge or marching between Underground platforms, but this bike is noticeably easier.The same applies when popping up and down stairs – you find yourself doing things with the S2L that you found ways of avoiding with other folding bikes. Folded size is a little larger than previous Bromptons because the comfy new Vitesse saddle is longer.With the saddle right down, we made a cube of 92.3 litres (3.3 cu ft), but the package gets bigger if you put the saddle at the top of its post and/or adjust it backwards, which lengthens the folded package and increases the volume to 105 litres (3.7 cu ft) or even more.To put that in perspective, it’s still 33% smaller than the Mezzo…
Is the bike really going to appeal to the iPod generation? We haven’t seen Tempest Blue or Kew Green (a nice local touch for a West London factory), but Flamingo Pink only seems to hit the spot under the right lighting conditions. In bright natural light, the matt finish and subdued hues can look washed out and lacklustre, but in the right sort of artificial light, the bike really sparkles. More generally, the combination of grey titanium, blue titanium (the seat pillar is treated to reduce scuffing), various shades of silver and shocking pastel pink may or may not appeal.
Once out of the showroom, those with smaller hands should be able to find a comfortable riding position. At long last, Brompton has come round to providing brake levers which are adjustable for reach, but with these handlebars, the levers have to be positioned vertically to prevent a clash with the front wheel when folding, or the front luggage when riding.
As mentioned elsewhere, luggage does pose a few problems. Brompton uses a standard frame-mounted carrier block which takes three sizes of luggage.These clear the standard handlebars (and the new P-type bars), but tend to restrict the brake cables on the S-type and if over- filled, could foul the handlebars. In practice, the standard Brompton Pannier and folding basket do fit, although it would be wise not to over-fill either. Playing safe, Brompton has introduced a new lower bag (and special low frame) called the S-bag. Produced by Dutch company Radical Design, the S-bag weighs 1.1kg – a little heavier than the Pannier, but lighter than the humungous Touring bag.The S- bag overflows with fashionable zips, pockets, ‘beam me up Scotty’ communicator holsters and all the other accoutrements of modern living. If you don’t hold with such style-things you’re probably the wrong person to be riding the S2L-X anyway. Naturally, the more fashionable youngsters loved the S-bag.
…We’ve seen lighter bikes, but none of them were practical commuters…
Like all new Bromptons, the S2L has a longer frame, so if you’re used to the old model, you’ll find a welcome centimetre or two of extra length here.The Pentaclip fixing also allows the saddle to go a little higher than the old fitting: up to a maximum of 97cm, which should make life easier for those who would consider themselves just too tall for a standard Brompton seat pillar. On the other hand, the handlebars are fixed at a relatively low 92cm (9cm lower than standard).We found that almost everyone who knew and liked the conventional Brompton said they preferred the old handlebars. On the other hand, there may be thousands of others who have rejected the conventional Brompton on the same grounds.They’re the people this bike needs to appeal to.
Conclusion
We’ve seen lighter bikes, but none of them were practical day-to-day commuters, which the S2L certainly is. Sub-10kg bikes don’t generally come with mudguards or luggage carriers, and in most respects this is a conventional Brompton, capable of doing just about anything a conventional Brompton will do. Once you’ve taken a deep breath and paid for it, titanium should last for many years without corroding or failing. Our only concern is with the surface treatment on the seat pillar, which seemed to show signs of mild scuffing after a week or two of fairly intense use.
Competition? The Dahon Helios SL is both lighter, and at £800, cheaper, but it’s hardly equipped for a daily commute, and we’ve heard a few grumbles about spoke problems. Dahon also produces the little Presto Lite, which is claimed to weigh 8.9kg, even in 3-speed form.We can’t verify this because we haven’t tried the bike, but at £570 (currently discounted to £520 or less), it’s a lot cheaper than the S2L.
Competition comes from within the Brompton stable too.We suspect many will opt for the M2L-X, which is £92 cheaper, almost as light, and with the advantage (for some) of more conventional upright handlebars.We’re very, very tempted.
Like the Routemaster buses featured last month, new folding bikes seem to arrive in groups of three.This is awkward for those who make a living testing bikes, and bad news for manufacturers too, because if the Mezzo had not been overshadowed by this month’s news from Brentford, it would have been very big news indeed.The Mezzo is a completely new folding bike: all alloy, 16-inch wheels, up-to-the-minute British design, and manufactured in Taiwan to keep the price within three figures. By any standards, that’s big news.
Gestation
To find the origins of the Mezzo, we need to go back a number of years. For some time, a British company called ATB Sales has marketed Marin bicycles in the UK. Actually, the Marin bit only accounts for 85% of ATB’s turnover, because as any mountain bike enthusiast will know, ATB employs Jon Whyte, and Mr Whyte is the designer behind the Whyte range of top-end mountain bikes, produced for, and marketed by, ATB Sales.Whyte also engineers some clever suspension designs for others, notably Marin, so this is clearly more than just a ‘Marin UK’ operation. Most British ‘manufacturers’ have offices on Junction X of the M6, staffed by bored over-weight sales-suits, but ATB has real design premises, staffed by real skilled people.This element is obviously of some importance to our story.
…this is clearly more than just a ‘Marin UK’ sort of of operation…
Five years ago, Jon Whyte produced the PRST1 or ‘Preston’ front fork. Apparently, the fork bears a passing resemblance to Preston, the fiery mechanical dog from Aardman Animation’s ‘Close Shave’. After sales of more than a million pounds, PRST1 spawned a folding mountain bike design exercise that turned into a full working prototype in 2000. We were lucky enough to see this extraordinary ‘praying mantis’ machine; heavy and unwieldy, but offering loads of gears, a conventional wheelbase, and full suspension. A bit impractical, but the lineage was clear – unlike most other folders, it was designed to appeal to the trend-conscious and wealthy young men buying top-end MTBs.
The trail then went cold for a few years, but ATB was busy behind the scenes, pouring money (some say £300,000) into an entirely new folding bike design.The key criteria were 16-inch wheels (the larger 347mm British kind, rather than 305mm Far Eastern), automatic folding catches, and (like the Birdy) a rigid hinge-free frame.To keep weight and complication to a minimum, the bike would have no suspension – unusual for a 16-inch machine.
In late 2004, the first hand-built prototypes were shown at the London Cycle Show, but manufacture took some time to arrange, and the first 50 or so production bikes have only recently been distributed to selected and trusted Whyte outlets. Sales aspirations are low for now – and expected to remain so against UK Marin sales of 23,000 last year – but ATB will ramp up production once the design has been de-bugged.
The Mezzo
Our test bike is an early production machine, so the spec is bound to change. It will be interesting to see whether our predictions as to where it should change prove correct. First, the frame.The Mezzo has a smart alloy frame, shot-peened to a rough matt finish, and topped with smart modern graphics and gunmetal grey anodising (silver will follow as an option). In terms of both product design and finish, it’s superb, and in a different league to the tasteless, and sometimes rather gormless Chinese things that usually fall out of the box. This is one of the first folding bikes with a proper design pedigree, and it really shows. In terms of looks.The only slightly questionable area is the strangely cranked handlebar stem, of which more below.
On the road, the deep oval monotube frame is stiff, but opinions vary as to the handling. Most people found the bike twitchy and unpleasant at first, particularly when accelerating hard. Quite why this should be, we’re not sure.The sub-100cm wheelbase doesn’t help, and the handlebars are some way forward of the steering axis, which imparts a rather odd feel. Other more complicated things like trail and steering angles can have an effect too. Suffice to say, it feels a bit strange.
…13.3mph – headline stuff in the small wheel Dark Ages, but well below average today…
Once you’ve acclimatised, you can ride a bit harder. Even standing out of the saddle results in no obvious frame twist, although the handlebars and the convoluted stem can flex under duress. But that’s only in contrast to the general rigid feel of the bike – it’s still better than average in folding bike terms.
Wheels and tyres are 349mm, as on the Brompton and Micro.This is great news, because it means a really compact package.There’s also plenty of technology in this size, giving a choice of low weight, high performance and long life (some tyres, arguably, providing all three). Unfortunately, the Mezzo’s smart-looking, custom-made Cheng Shin tyres seem to be some way off the cutting edge. Supplied only in 55psi kevlar-reinforced form, the tyres are light, but rather sluggish, and a bit of a disappointment on such an ostensibly sporty bike.
Rolling speed on our test hill came out at 13.3mph, which would have been headline stuff back in the small-wheel Dark Ages, but is well below average today. Normally with a new tyre we’d try a few experiments with tyre pressures and temperatures, but with maximum pressures of 55psi, there didn’t seem much point. Far Eastern manufacturers love kevlar, but we’ve yet to see any real puncture-resistance benefits, and in small sizes the rolling resistance can really suffer. If you buy a Mezzo – and we don’t want this to put you off – trade up to Primos, Schwalbe Stelvios, or even (dare we suggest it?) the yellow flash non-kevlar Brompton tyres. Any of these will The Cheng Shin tyres are a transform the bike. bit disappointing
The Mezzo will be available in two forms – the i4, fitted with Shimano’s long-in-the-tooth Nexus 4-speed hub, and the d9, complete with the delightfully compact Shimano Capreo derailleur. Following Shimano’s recent production problems, the Capreo-equipped bike is unlikely to be available before May, so we’ve only had a chance to try the 4-speed. Good and bad news here – it’s a solid, stodgy, reliable hub that can be pedalled through most changes without complaint, but it’s inefficient, and it has a narrow (184%) gear range. It also weighs nearly as much as a modern 8-speed hub.
With market research suggesting that folding bike users would demand low gears, the ATB engineers chose unusually low ratios – top coming out at a rather pedestrian 69 inches.This is, quite simply, too low (lower than the new Brompton 2-speed, for example). We’d suggest the i4 needs at least another gear to be competitive in the cut and thrust commuter world.The company intends to give the sportier d9 an even lower 64-inch top gear, suggesting it will run out of steam just as the Brompton rider in front shifts casually up to Gear 5, with one more to go.Yes, the i4 (and the d9 if they don’t fix the problem) will be up to wobbling around yacht marinas, passing Stridas and other low-aspiration folders, but in our opinion it deserves better.They really should think again.
Folding
Folding Pedal
Perhaps wisely, ATB claims only that the Mezzo ‘unfolds in no more time than it takes to tie your shoelaces’. Folding times tend to be as long as the proverbial bit of shoelace: we’ve seen both the Birdy and Brompton folded in less than ten seconds, but we’ve seen other people struggle to fold the same bikes in five minutes. No doubt the Mezzo will be much the same.
What matters more than outright speed is consistency and repeatability. Try folding any bike in a bitterly cold drizzle on a dark station platform and you’ll appreciate what this means. It’s an area where the Brompton tends to excel, and the good news is that the Mezzo is also reasonably easy.
As with most folding bikes, it’s important to fold and unfold in the correct order or you will get in a tangle and possibly do a whoopsy to your accoutrements. In this case, you start by positioning the right-hand pedal towards the rear and rotating the handlebars fully anti-clockwise. It’s now possible to lift a safety catch (unlike the rear-suspended Brompton, the frame locks in place) and rotate the rear wheel under the bike, which now stands on the rack.This ‘lazy fold’ in ATB parlance, sits rather like a parked Brompton, and it’s small enough to put aboard the roomier sort of train. Incidentally, if you have a beautiful teak-effect parquet floor, don’t stand the folded Mezzo on it.The front mudguard sits on a football stud, and the rear reflector stays protrude far enough to leave some nasty gouges.
Front-wheel quick release and safety catch
…by slowing the bar, the second catch is arguably counter-productive…
To go smaller, release the front axle quick- release, flick off a safety catch and fold the front wheel and mudguard assembly back until the mudguard stay engages with a catch on the rear frame.The seat post can now be released and slid fully down, where it should engage with a lower stop bolt, holding the package together, rather like the Brompton or Birdy. Finally, there’s a fiddly safety catch to undo before the Mezzo’s trademark over-centre stem catch can be flicked up, allowing the handlebars to drop down against the front wheel.
Fully loaded. The front wheel has swung round and back to clip against the frame. The handlebars are hanging free, but the seat pillar has engaged with a stop to prevent the rear wheel unfolding
The handlebar hinge partly engaged. The spring-loaded bar is lifting up and over the curved plate. As the hinge closes, the bar snaps into place underneath the plate, securing the joint.

Actually, there are two of them, engaged.The spring-loaded bar is lifting up and over the curved plate. because the catch holding the rear As the hinge closes, the bar snaps frame is similar, but the handlebar into place underneath the plate, stem is the safety critical one.The securing the joint hinge itself is crude and quite loose on our sample, but it plays a relatively minor role once the catch is in place. The real strength comes from the engagement of curved mating faces on the upper and lower seat pillar, Bar which are pulled tightly into engagement by the catch.This Fully closed, the bar is now consists of a out of sight and the two metal bar curved faces have mated, that lodges producing a tidy joint. Note the safety catch below Hinge Plate beneath a cleverly-shaped alloy plate. As the spring-loaded bar pushes under the plate, the hinge locks firmly together, but it can be released in an instant by pushing the bar back the way it came.The fiddly secondary catch was insisted upon by nervous lawyers, and serves little purpose. In fact, by slowing the advance of the bar – which tends to work best when snapped smartly into place – the second catch is arguably counter- productive.The word on the streets is that regular commuters may wish to remove it, but you didn’t hear that from us, or from ATB for that matter. Fully folded.The front wheel has swung round and back to clip against the frame.The handlebars are hanging free, but the seat pillar has engaged with a stop to prevent the rear wheel unfolding
We’re always wary of new catch designs.This one is clever, but it relies on fine engineering tolerances.The bar can be adjusted to take account of wear, but this is something that would have to be done with care. In use, it’s best to be assertive, because a half-hearted fold can result in the catch failing to go all the way home, leaving some play in the joint.We expected it to work best oil-free, but the excellent manual suggests greasing the catch and oiling the hinge once a month, so we’ll accept their judgement. Even allowing for poor maintenance, we don’t think the joint could separate in use. However, there must be a question mark over the long-term survival of the hinge assembly, which started loose on our bike and is unlikely to improve.
Something of an omission, but easily rectified, is the lack of a clamp to hold the folded handlebars in place. Long experience has taught us that loose bars will sooner or later trip you up as you run for the 17.44.The Mezzo comes with a pair of (unbranded) folding pedals, but only the left one is really useful. Push the pedal body inwards and it pivots down, leaving a bearing block protruding about 5cm.
Those familiar with folding bikes may be wondering where the chain has gone. A short tensioner arm keeps the chain taut in normal use, but when the bike begins to fold it soon reaches its limit. At this stage, two pegs take over, lifting the chain and wrapping it round the chainring.The process is even crueller than it sounds, because like the Bike Friday, the rear frame pivot is offset, so as the frame rotates down and forward, the wheel ends up some degrees out of line with the chainring, distorting the chain sideways.Things may be more complicated with the derailleur, but on our variant this clever mechanism works well, peeling the chain off and returning it without any oily calamities. Unfortunately, the same isn’t true on the road: jumping over a small curb, our chain popped off the chainring and got tangled up with the pegs, resulting in lots of swearing.
…folding the hub-gear version is easier and cleaner than the Birdy…
Niggles apart, the Mezzo really is quite easy to fold, and it also produces a reasonably small package.The derailleur may be more demanding, but the hub-gear version is definitely easier and cleaner to fold than the Birdy, if rather more involved than the Brompton, which really can be done with your eyes shut with practice.
Unfolding is arguably easier, thanks to the clever over-centre catches.These thump into place, producing a rigid joint with a satisfying click.You only really need to get your brain in gear when reassembling the front wheel. Obviously, the wheel has to go all the way back where it came from, allowing the catch to fall into place, and you must remember to follow this up by tightening the conventional quick-release.
Folded size is good, without breaking any records. As delivered (personal saddle and handlebar adjustment will make a difference), the folded Mezzo is 33cm wide, 64cm tall, and 75cm long.That’s a folded volume of 158 litres or 5.6cu ft, which is smaller than the Birdy, and marginally smaller than comparable 16-inch bikes, such as the Pashley Micro, Dahon Presto or Tactic Panache. As usual, the Brompton is in a class of its own, occupying around half the volume of the other compacts, but the Mezzo runs an acceptable second place. It’s a neat and practical folding bike.
Weight seems disappointing, but as with the Brompton, that’s an illusion brought about by the small folded size. In fact, at 12.2kg (26.8lb), the Mezzo i4 is a shade lighter than the equivalent Brompton M6 (but without dynamo lights, of course). A lighter hub, pedals and tyres could bring the weight down to 11.6kg (25.5lb), so there’s plenty of room for future developments.
Accessories, Adjustment & Servicing
Initially, the Mezzo comes with very little in the way of accessories, but we’re pleased to see a proper pair of mudguards.The front one is structural, so it’s an indestructible alloy affair. Otherwise, there’s just a bell and a slightly naff-looking saddle-mounted LED rear light. If ATB is serious about the folding world, the Mezzo needs proper lights, and some sort of luggage system. It has a rear rack, but in the morning commuter maelstrom, the man fiddling with panniers and bungees is the man who misses the train.The bike needs a custom rack-mounted bag and quick-release system, and we’re told there’s one on the way. Proper frame-mounted LED lights are being developed too.
Excellent news for taller people is that the saddle goes up to 107cm, which is way taller than the opposition. Unfortunately, the bars are adjustable over a rather limited height range of 105 down to 102cm, which is too tall for shorter folk. And, at a shade under 100cm, the wheelbase is a bit short, putting the micro-adjust saddle too close to the bars for taller people. Actually, nearly everyone found a comfortable position on the Mezzo, but not all.The help of the sort of dealer willing to discuss inside leg measurements and crotch comfort zones is essential here.
Brakes are Promax dual pivot calipers. As with many folding bikes, the short wheelbase effectively dictates the front wheel braking force, while a convoluted cable run limits power to the rear.When new, a mighty heave on the rear lever gave a barely adequate stopping force of around 0.33G without quite locking the wheel. After a few miles, this improved slightly, to the point where the wheel could just be locked up. At the front, the Promax caliper easily achieves 0.61G, but at this point the rear wheel is beginning to lift. In general, braking performance is similar to the Birdy, but the longer wheelbase on the latest Brompton helps to keep the rear wheel on the ground for a little longer.
Conclusion
The Mezzo is a very interesting design.The faults might sound serious, but they’re mostly in the detail, so upgrading should be easy.We’d like to see some work done on the tyres, with the option of something like the Stelvio, or a Primo derivative as soon as practicable, enabling the bike to pull higher gears.To be really competitive, it needs a top gear of 80 inches, or even more if the rolling resistance can be sorted.
As for the gear system, the Mezzo has a full 132mm frame drop-out width, so ATB can fit any hub it wants.The Sturmey or Nexus 8-speed would be ideal, giving a much bigger gear range than the Brompton, and matching the more expensive Birdy derivatives.
Would we buy it now? We’d certainly get down to the nearest dealer for a test ride. The Mezzo is the first really serious challenger to the Brompton. It doesn’t fold quite as small, but it looks techier, and with the right running gear it could outpace it. Interestingly, although most Brompton owners rejected our sample for a variety of reasons, those who had decided against the Brompton were delighted. Key observations were plenty of saddle height and a rear wheel that didn’t fold under when lifting the bike. Price will have an influence too – at £595, the Mezzo represents quite good value for money.
We live in interesting times. As bits of Antarctica drop off, and global meltdown accelerates goodness knows where, it’s business as usual in the UK – more and bigger cars doing more miles, renewed talk of a railway closure programme, and low-impact cycling right off the political agenda. Meanwhile, the chairman of Shell is riding a Brompton to work and making some very anti- oil comments. Whatever next!
Fear not! A to B brings you the usual eclectic mix to reverse the trends: half price bicycles, Routemaster buses, all the usual technical bits, plus gripping tests of bicycles and accessories. And to get you in the mood for a CO2-lite holiday this summer, we have reports on folding bike breaks in Switzerland and Wales.
ORIGINAL ARTICLE FROM FEBRUARY 2005.
The Panasonic Will has been out of production for some years.
We’re often told that folding electric bicycles are the next big thing, but the technology always seems to be just around the corner, in a container on the high seas or being re-evaluated somewhere far away. In other words, it just isn’t ready.
Why would anyone want a folding electric bike? Sad to relate, there is growing demand – we kid you not – for electric folders that can be carried to the local park in a car boot and toodled around, giving the rider some virtual exercise. A frightening vision of the future if ever there was one: herds of doddery greys ripping up the ozone layer for a bit of fresh air.
But every new technology has its frivolous applications. Somerset is big country and some towns are relatively inaccessible without a car. If we wanted to get to, say, Radstock (not that we ever do), we’d take a folding bike 18 miles on the train to Frome and cycle the remaining eight miles. Actually, Sustrans is working on a level-ish path, but otherwise, think serious hills. An electric-assist folding bike would make a lot of difference.
Similarly, for someone living in the South Hams of Devon, or just about anywhere in the Peak District, this sort of technology would make a Home Counties-style train/bike commute more practical. It sounds easy, but to get our business, and break into the touring/folder, commuting/folder markets, the bike would have to outclass an enthusias- tically-ridden Brompton or Birdy, and to date, there’s no sign of this happening.We’ve seen nothing that can be swung easily onto the train, and/or manage our archetypal 16- mile round journey, but year on year they improve.
WiLL-Power
State-of-the-art in early 2005 is the Panasonic WiLL. Actually, the WiLL has been around for a while, and is in any event based on the older Porta-Ranger model that was already knocking on a bit when we tested it in 2001.There aren’t many similarities though.The staid Porta-Potty frame has been replaced with one of the prettiest alloy designs you could hope to make the acquaintance of, complete with strangely unmatched wheel sizes – 20-inch rear and 18-inch front.
The power unit is lithium-ion, but this isn’t new either, having first made an appearance in Japan in December 2003, arriving in Europe on the Swiss-made Biketec six months later. Significantly (or perhaps not), Giant came very close to upgrading its Lafree to the lithium system in 2004, but changed its mind. Just to recap, lithium-ion batteries are light, but they need some clever electronics.The Panasonic system has two battery options, one of 160Wh (about the same capacity as the Lafree, but at 1.6kg, less than half the weight), and a smaller unit of 80Wh, weighing just a kilogram. In other words, the weight of the battery is of no real significance in the greater scheme of things.
Panasonic has made the bigger battery available to other manufacturers, but its own folder comes with the one-kilogram job, so don’t expect to go very far.
On the Road
First impression on the road is that the Shimano SIS 7-speed derailleur is missing at least one gear at the top end.This is quite common with Japanese folders, which leaves you wondering how they ride ‘em over there. Do all cyclists wobble along at 12mph? Or is it just the folding bikes that get left in the gutter when bicycles, mopeds, car and trucks roar away from the lights? We’d love to know.
The result of limited gearing is a strictly limited top speed. You can cruise at around 12mph, but even in a knee-spinning emergency, you won’t go much over 14mph with a 61-inch top gear. This is seriously debilitating stuff and leaves the Panasonic floundering in the wake of all but the humblest unassisted folding bikes on the flat. We wouldn’t even attempt to storm the rolling Somerset downs with gears like this. More usefully, bottom gear is low too. At 28 inches, it would be low by any standards, but on a crank-driven electric bike, a gear like this will climb any hill South Somerset can produce, albeit at a snail’s pace. Again, we’re confused. Are Japanese suburbs very, very hilly?
Rolling resistance is acceptable, rather than exciting.The 40psi Cheng Shin tyres are a ‘trad’ design, so don’t expect sparkling performance. Actually, they roll quite well at 50psi, hitting 13.3mph on our test hill, but this is a big bike, and these days we expect 20-inch machines of this size to coast a good 1mph faster than that.
The 107cm wheelbase and handlebar height of 97cm are acceptable, but at 79cm – 94.5cm (plus another centimetre or two for the daring) the saddle height is a shade low. The general impression, from the low saddle, uninspiring gear ratios and lethargic tyres is that the Panasonic would be blown away by most unassisted folders in the traffic light Grand Prix. Not a very good start.
Power Assistance
In common with all the best electric bikes, the Panasonic drive system is almost invisible. The motor is part of the bottom bracket, and more or less hidden by an oversize chainguard. The tiny battery sits above it, but you could mistake it for a bit of frame tube or a water bottle.
The power switch is on the handlebars, offering two levels of assistance, or nothing if you prefer.The ‘Off’ setting leaves you with a typical, under-geared folding bike as one might expect, and ‘Lo’ is too Zen-like to be worth discussing. It sort of whispers encouragement. ‘Hi’, on the other hand, offers quite perky acceleration, as a torque-sensor engages the motor to match your pedal strokes.This feels exciting, but it’s all over very quickly. Above 10mph in top gear, the motor begins to run out of steam, and by 12mph, your legs are whizzing a shade faster than most of us would prefer, and you’re on your own. Progress continues thus until you confront a steepish hill, which the bike saunters up in one of its higher ratios, only dipping into the 300 watt peak power reserves on the steepest bits. Our meanest, cruellest gradient is 17% (1:6) and the Panasonic rasped gently up in 2nd gear – we never found an opportunity to use 1st in anger.
This steady, but rather tedious progress continues for about three miles, at which point the first of three ‘fuel’ warning lights flicks off (the separate battery gauge still showing four out of five lights, incidentally). At seven miles the second instrument light is extinguished, with the battery still displaying two out of five. Rather disturbingly, the battery meter then goes from half to empty in less than a mile, and by 7.8 miles, both gauges are flashing, indicating reserve. It then changes its mind, and does another three miles before conking out at 10.8 miles. Average speed is a woeful 10.6mph.
This sounds rather dismal against electric bikes that can run for twenty miles or more at 17-18mph, but at 17.3kg, the Panasonic is the lightest electric bike on the market. Not that long ago, we were testing conventional folders weighing that much, so it’s quite a good performance all things considered. And in hilly country, 10.6mph is better than it sounds.
The peaks correspond with power consumption in the different gears. The grey area is wasted power
Charging is excellent. Lithium-ion batteries need clever technology to stop them going pop, and the same mysterious electronics give an uneventful and rapid charge of about one hour 40 minutes – the fastest we’ve seen (Panasonic suggests 40 minutes longer). Mind you, it’s also the smallest battery we’ve seen. Efficiency, both charging and running, is similar to the NiMH-powered Lafree. Power consumption is a nominal 7.4Wh per mile, or 10.7Wh if charging losses are taken into account, as they must be, unless you have your own solar/wind/hydro power plant. Just for the record, there are few powered vehicles (except of course, for the traditional bicycle) that can beat that.
Accessories
Strangely, for a machine with a state-of-the-art alloy frame, and lithium-something-or-other battery, the WiLL is equipped with some frightful accessories. The brake blocks, callipers and cables are cheap and profoundly ineffective.The front manages a best stop of 0.54G, which is tolerable, but even with a mighty heave, the rear brake only scrapes up to 0.22G. If you’re wondering how to interpret these G-force readings, 1.0G is the force of gravity, which is a bit difficult to achieve horizontally. A good stop is 0.7G, a reasonable one 0.5G, and 0.22G is pathetic. In practical terms, the WiLL comes with one functioning brake.
The bottom-of-the-range Shimano derailleur we’ve already mentioned, there are no lights or rack, but the WiLL has a little stand, and a bell. Mudguards are those floppy plastic things, which prove better than nothing, but not much. All a bit disappointing on a machine costing £1,200, give or take an exchange rate fluctuation.
…Why, oh why, oh why, do manufacturers never listen?
Folding
Remarkably good. The electrical bits cause no complications, so folding the WiLL is much the same as any other 20-inch job.The handlebar stem has an elegant catch, rather like a convex version of the Brompton U-clamp (a round bar, in other words). Once released, the handlebars fold down and clip into place, something that always gets top marks in our book.The mainframe hinge is a bit trickier, and you need strong fingers to push back the safety catch, heave the lever, and winkle the locking bar from its lair in the frame. Once done, the bike folds in a trice, and with the attractive MKS FD6 pedals folded (best accessories on the bike), it’s done. As usual, one of the folding pedals is superfluous, so they could have saved a few quid there, and in contrast to the handlebar stem, the frame doesn’t clip together, so the package continuously falls apart.Why, oh why, oh why, do these manufacturers never listen?
Folded size is 41cm wide, 69cm tall (or 67.5cm with the useless saddle stem rear reflector removed), and 88cm long. Folded volume is 249 litres or 8.9 cubic feet.That should be acceptable on all but the busiest trains, but it’s a little bulkier than the Dahon Roo/Sparc and much bigger than Honda’s little Compo, formerly the WiLL’s sworn enemy, but now apparently withdrawn.
Conclusion
We don’t think £1,200 bicycles should have rubbish brakes and indifferent tyres, but the Panasonic WiLL is also the lightest electric bike around, and it narrowly outperforms the other two super-lightweights: the Dahon Roo and Honda Step Compo.
With another gear, lighter, more effective tyres and brakes, and a bigger battery, the WiLL would weigh about the same but go nearly twice as far at a sensible speed. It’s not for us to tell Japanese multinational corporations how to run their affairs, but those changes would make it a jolly interesting machine.

There’s a real demand for carrying children on the Brompton, something we can vouch for from personal experience. It’s also probably the most common question we get asked. Integrating the bike itself with rail or bus is straightforward, but children make life much more complicated.Trailers are great, but even the most compact takes up more space than a folding bike designed for an adult, so they present a bit of a challenge on public transport.
When Alexander was two, we solved the problem by adapting a conventional child seat to fit on a Brompton seat pillar, a device that went on to give four years of priceless service.Wonderful for long trips, the child seat was nevertheless a bit clumsy for shorter journeys to shops, and later, to school. Fitting and removing it required an allen key, which was invariably at the bottom of a bag, in the wrong pocket, or worst of all, on the kitchen table at home. Strapped on top of the folded bike, the seat produced a small package, but the operation required a strap, which was invariably at the bottom of the bag, on the kitchen table, etc.
Our SP Brompton trailer bike proved to be a practical alternative – great for longer rides, but in terms of folded size, effectively two Bromptons. And guess who gets to carry the two Bromptons and the bag?
…ten minutes later, wife battles through traffic to deliver child…
The ITChair
When we first came across the ITchair, it seemed to promise a practical tool-free solution for short trips, although we were sceptical that a Brompton was roomy enough for two, or that the device could be fitted and removed as quickly as was claimed.
Note the folding footrests and frame yoke
Who is it aimed at? Leisure seems the obvious market, but we’ve heard from several readers who long to eliminate that daily school-run nonsense: dad rides Brompton past school to station, ten minutes later wife battles through traffic in Volvo to deliver child, then runs home empty.The ITchair promises to carry a smallish child a modest distance, then fold away more or less out of sight, with the exercise being repeated in the evening, or not, as the case may be – it sounds like a flexible solution.There are a few complications and traps for the unwary, but by and large, it really does what it’s supposed to do.
The device is disarmingly simple.You get a steel tube (aluminium is in development), fitted with a yoke at one end and a clamp at the other.To fit it to the bike, you slide the cushioned yoke over the frame tube and push it up against the frame hinge plate, where a hook on one of the yoke arms engages with the plate, to prevent the ITchair from lifting off again. At the other end, the clamp goes round the seat post and is secured with a standard hinge clamp lever borrowed from the Brompton parts bin.
The ITchair can even be used as a temporary seat on the train
Newer Bromptons have a subtly different hinge, but the ITchair cleverly gets around this with a reversible yoke, giving two alternative hooks.This operation needs an allen key, but unless you regularly swap Bromptons of mixed vintage, you will only need to do it when initially setting the ITchair up.
From the top of the tube, a seat post protrudes horizontally, giving about 10cm fore and aft adjustment to the child saddle, and a pair of neat motorcycle footrests pop out lower down.
In Use
Alexander is slightly taller and slimmer than the average very-nearly-six year old, and as he can ride the ITchair with reasonable ease, we’d say it was suitable for children of up to six. Climbing aboard will be a problem for a nervous child (some refused to even consider it), but the more outward bound types scramble on and off like monkeys, an operation made easier if the adult is already firmly aboard.
The clamp has to do a lot of work, but looks strong enough
The ITchair adds virtually nothing to the size of the folded package
Once in the seat, Alexander’s knees nestled comfortably below the handlebars.You might think handgrips would be useful, but in practice the child either holds the bars, puts his hands in his pockets, scratches his head or does a Mexican wave. The saddle and footrests give plenty of stability, and the rider’s arms tend to cradle the child, so they really would find it hard to fall off.With a bit of experimentation we found it was surprisingly easy to take three hands off the handlebars, so indicating is not the problem you might expect. One word of warning – if the child holds the gear shift and you change up unexpectedly, you will squidge a tiny finger.
For younger children, this central position feels secure, and there’s a perceived advantage in keeping an eye on the child too. In theory, you can carry a baby in a suitable carrier, but for the sake of your knees, you’ll need to find something very narrow. Sadly, we had neither baby nor carrier to hand, but it’s clearly possible.
Disadvantages
The primary disadvantage for the rider is pedalling with your knees further apart than normal.This has little effect on power output, but we wouldn’t recommend putting knee joints through too much of this sort of stress.With a large five-year-old and an old short-frame Brompton, we’re looking at a worst-case scenario. Any combination of a smaller child, a post-2004 bike and a saddle set well back will make life much easier. A narrow child saddle would help too – we used a conventional saddle and found it annoyingly wide even without a child on board.
Whilst looking for disadvantages, the increased weight over the front wheel might encourage a slide on gratings and low kerbs.We didn’t experience any problems, but would certainly suggest riding with more care than usual.That’s obviously a matter of common sense with any child carrier, but our lower rear-mounted child seat handled superbly even at high speed – something we wouldn’t recommend with the child upfront.
…with 10kg in the bag, an 85kg rider and a 20kg child, we’re on the limit…
Staying with weight, Brompton suggest a gross bicycle load of about 115kg.With 10kg in the front bag, an 85kg rider and a 20kg child, we’re right on the limit.This might be all right, and it might not – we certainly noticed some slight fretting where the ITchair pushes up against the hinge, indicating that the bicycle frame and saddle stem had been bowing slightly under the stress. Once again, this is an extreme example – most adult/child combinations would be safe enough.
Folding
Folding takes just a few seconds: release the clamp, lift off the ITchair, fold the bike, and reclamp the ITchair to the lowered seat pillar, sticking out and down along the left side of the bicycle frame. This leaves a folded package little bigger than normal. It’s a bit heavier, adding 1.6kg in this case, but lighter and smaller than the alternatives. Incidentally, Alexander rather enjoys carrying the ITchair himself, but you have to watch five-year-olds – they’re liable to put things down and wander off. Luckily, you’ve got the bike. Another useful feature, as we discovered on a busy post-Christmas train, is that the ITchair can be clamped to any suitable vertical post, making an extra seat. Small boys love this kind of thing.
Conclusion
The ITchair is far from ideal, but it’s a brilliant bit of lateral thinking, and within reasonable limits of child size and weight, journey length and so on, it really does perform well. The real proof is whether we use it ourselves. In practice, the ITchair proved hard work on our steeply inclined school run, but has been used almost without exception on rail trips, where compact size and folding speed are more important.To date, we must have used the chair on a dozen trains (some quite busy) and ridden 50 miles or so.We very much wish it had been around three years ago, but we’re delighted to have found it now.

We’re not actually that keen on bags since the railway companies got folder-friendly, but they have their uses.Yachtsfolk need to protect their bikes from salt spray and flying bowsprites, whatever they might be, and the same principle applies to those regularly checking a bike in as anonymous luggage, whether at the airport, the restaurant or even (particularly even) Mrs Hampton’s Bordello & Old Time Massage Parlour. Of course, you may think you need a bike bag for another reason; whatever, it will leave your wallet thirty quid lighter and your Brompton nearly a kilogram heavier.
The Bigfoot Bag is made in Britain, from grey, green, navy blue or red cordura. It’s a waterproof fabric, but you can expect the untaped seams and very long zip to leak under extreme conditions.The bag has carrying handles and a shoulder strap, makes a nice snug fit around a typical Brompton and will just accept a bike fitted with the extended seat pillar too.The bag also comes without branding to reduce the risk of theft. Maybe, but that’s not much use if the thief is working on the lucky dip principle.
At 910g, the Bigfoot is mid-range in the Brompton bag world – somewhere between the Brompton cover and the ‘B’ bag reviewed in A to B 44. Just for the record, the ‘B’ weighs 2.3kg and gives serious protection; the basic Brompton cover weighs 290g and gives very little protection; and the super-lightweight cover we use ourselves for libraries and the like, weighs 100g and gives no protection at all. Horses for courses.
We wouldn’t recommend buying a bag unless you’re sure you need one, but for certain applications,something of this weight could be quite useful.The downside is the 910g of extra baggage, and a packed size of about 40cm x 10cm x 10cm.

The story of folding bicycles in the USA is unusual. In the UK and Europe, folders are everywhere.They appear every working day on buses and trains during commuting hours, and are seen tucked away in offices and other workplaces in all major cities.They are, as our saying goes, ‘as common as crabgrass’.
Not true in the USA. Folders are seldom seen on American buses and trains. Almost every American bus now has a rack on its front which will carry two cumbersomes, and full-size bikes are allowed on most trains whenever they do not inconvenience other passengers. A visitor from the UK could ride an American bus or train for months without ever seeing a folder in use during commuter hours or any other time.
Folding bicycles do sell here.Well-stocked bike shops will carry at least a couple of models, usually Dahons, and they are also sold by catalogue retailers like L. L. Bean & Co. So where are they?
Welcome to the world of recreational vehicles (RVs). All over the USA, these vehicles lumber along American highways and streets.They come in all sizes and types, from small collapsible trailer-campers which cost the average worker a month’s wages, to luxurious behemoths as large as an intercity bus which cost more than the average house.
These RVs, at least the larger ones, are considered one of the common pests of America’s roads and suburbs.There are millions of them and they are everywhere.They block streets, clog driveways, create road hazards on freeways, and are driven and loved by millions of Americans.
Some are trailers which are designed to be towed by standard cars and trucks. Most, especially the larger ones, are built on truck or bus frames and are fully self-powered and self-contained. A whole industry has developed to support these vehicles.There are literally thousands of campgrounds for them. Some are publicly owned, but most are privately operated.They can welcome either a few or a few hundred of the RVs.The largest RV campgrounds operate like small towns, and one can stop there for a night or a month or longer.
It is in these campgrounds that folding bicycles are so useful.The traveller with a trailer can hook it up to water, gas and electricity sources, and then use the towing car or truck for local transportation. But the owner of a self-propelled RV needs a compact and dependable personal vehicle for use around the campground and for trips to nearby shops, etc.The folding bike has become such a natural part of RV life that some dealers supply a free bike with every purchase.
Most of these RVs are kept at home and used for weekend or vacation trips, but there is a new species of RV owners who have no home.These are the ‘full-timers’ who have sold their homes and live in their RVs all year long.They have their own clubs, such as the Good Sam Club (www.goodsamclub.com), Escapees (www.escapees.com), and Loners On Wheels (www.lonersonwheels.com).
The RVers are the modern American nomads.The clubs can provide insurance, travel information, mail forwarding, medical referrals and anything else that the club member might need and be willing to pay for.The full-timers also have a magazine (www.workamper.com) that matches RVers with part-time jobs so that they can show some income during their travels.The usual agreement is an exchange of a free campsite (with all amenities provided) in return for perhaps 16 hours of work per week. Some arrangements pay an hourly wage in addition to the free facilities, and others do not.The RVers make their own agreements with the employers, and many follow an annual circuit and return to the same jobs year after year.
There are also many volunteer opportunities in our National Parks and National Forests.The government provides campsites in return for a few hours of volunteer work each week and all the beautiful scenery one can absorb. Thousands of RVers take advantage of these opportunities every year.
It would be wrong to give the impression that these ‘full-timers’ are people who have nothing better to do than to rumble around going from nowhere in general to nowhere in particular. Many RVers are highly skilled in a particular field and need to relocate from project to project. Here in Southern California we often see RVs in use on movie and TV locations in a variety of support activities.The most luxurious ones are used by actors as homes in less salubrious locations.
There are millions of RVs on the road, and not all of them are vacation toys.They perform many useful functions and provide travelling homes for thousands of workers. Kay Peterson described it best in her book, Home is Where You Park it.
When I take my Brompton L5 for an early morning ride through the local neighbourhoods, I usually count 10-15 large RVs per hour, and at least as many smaller ones. I have no idea how many folding bikes are hiding in those vehicles, but I do know that the RVers are probably the largest group of folder buyers in the USA. So don’t despair if you visit the USA and do not see folders where you expect to see them.There are many thousands at large, but one has to look inside the RVs to find them. As the old- time salesmen used to say, ‘Ya gotta know the territory’.
Produce any interesting machine and someone will want to customise it. Engineer Steve Parry has been producing custom folding bikes to order for over a decade – concentrating on the Brompton in recent years.
In practice, you can order a Brompton from Mr Parry with just about any choice of parts and accessories, from the single-speed on this page to the all- singing, all-dancing 14-speed overleaf.
The basic single speed weighs 9.7kg (21.3lb) – around two kilograms lighter than a standard L3. This weight saving is achieved largely with high-tech materials: titanium/carbon fibre telescopic seat pillar, carbon fibre forks, stem and cranks, with MKS demountable pedals.
The single-speed rear hub is a Shimano freehub with all but the 11-tooth sprocket removed to save weight. Unusually, the bike is fitted with slightly oversize Birdy 18-inch wheels and Schwalbe Stelvio tyres. Price is £1,200 – broadly the same as the equivalent Bike Friday, Airnimal or Bridgestone Moulton.
In contrast, the Rohloff version features every conceivable accessory and weighs 13.9kg (30.5lb).The seat pillar is the same, but the lightweight saddle has been replaced with a Brookes leather item, and the cranks are Shimano 105.The handlebar stem is carbon fibre again, but this time with integral suspension. Brakes are superb – Hope hydraulic discs front and rear, giving a best stop of around 0.75G before lifting the rear wheel.The Brompton rear rollers are replaced with SP narrow discs and the rear suspension is fitted with a hook to prevent involuntary folding. Finally, there’s that hub… Steve fabricates his own rear frames to accommodate the much wider 14-speed Rohloff, but the folded size of the bike is little changed, and the system works well. Price? About £2,000 depending on the exact spec.That’s about the same as the Birdy Grey or Airnimal Ultima.

“Could you tell us the options for putting very low (sub 30-inch) gears in a folding bike? Which folding bikes will accept a Rohloff hub gear? It’s very hilly around here.”
Margaret Lunnon, Coulsdon, Surrey
Alot depends on whether you are prepared to put up with a general lowering of the gears, or are hoping to keep the high gears as they are.The simplest and easiest solution, common to most small-wheeled bikes, is to fit a smaller chain ring.These are cheap and available in a variety of sizes. An even cheaper answer with hub geared bikes, is to fit a larger sprocket. Most small machines come with 13- or 14-tooth sprockets and most will accept a much larger sprocket, giving an instant and cheap gear reduction. Bear in mind, though, that these solutions lower all the gears and have no effect on the gear ‘range’ – the difference between first and top gear.
Schlumpf Mountain Drive - the assembly fits into the bottom bracket
There are many options to increase the gear range, some more practical than others. On a derailleur bike, larger sprockets and long-arm derailleurs tend to be impractical with small wheels, but the other extreme of fitting a small top-gear sprocket and smaller chainring is fine, if a little complex.The Shimano Capreo system is specifically designed for small wheel bikes and gives a gear range of almost 290% from a very neat little unit. Assuming a just practical 80-inch top gear, the Capreo would give ratios down to 28-inch, just inside your requirement.This system is available on the Birdy White and the new Mezzo D9, and can be retro-fitted to most derailleur machines at a price.
An easier solution open to just about every folder is the Schlumpf Mountain Drive.This is a little hub-style gear set that fits inside the chainring. In direct drive, it has no effect, but click your heel on the little control button and the bike changes down to a low ‘hill-climbing’ set of gears.The Mountain Drive gives a reduction of 2.5:1 and the similar Speed Drive a more reasonable 1.65:1. Assuming a top gear of 80 inches, and a 3-speed hub, the Speed would give a bottom gear of 27 inches and the Mountain an almost unusably low 18-inch gear.With a wider range hub, the effect is even more pronounced. The nice thing about this system is that there are no cables to worry about, but it’s heavy, quite expensive and somewhat inefficient in the more extreme ratios.
Brompton Wide Ratio Conversion - 12/18t sprockets squeezed onto a standard 6- speed hub
My personal favourite is a wide-range conversion of the Brompton 6-speed.The standard 6-speed has a range of only 215%, so try as you might, you won’t get anywhere near your 30-inch target and keep a decent top gear. But fit 12- and 18-tooth sprockets to the Brompton hub and the range increases to 282%.This is wide enough to give a range from 80 down to 28 inches, with good efficiency. Unfortunately, there are technical issues involved, and no one produces a kit at present, although I understand this omission is being rectified. More in a later issue.
Particularly fashionable at the moment are the 8-speed hubs from Sturmey Archer and Shimano.The Sturmey is designed around very large sprockets and is thus too cumbersome for most small bikes.The Shimano is much more practical, and its gear range of 307%, would give a bottom gear of 26 inches with our 80-inch top gear. Several small- wheelers are available with this hub, including the Airframe, and conversions are available for most small-wheelers. Even the Brompton can be adapted, although the extra weight and folded width would be a disincentive for regular commuters.
Rohloff 14-speed - the widest range of any hub gear
Finally, we come to the Rohloff 14-speed hub. This offers an enormous gear range of 526%, but it’s a big, brutal device, and more or less doubles the price of a typical high-end folding bike.The range is as much as most people could ever use, from a wobbly walking pace, to a flat-out down hill top gear. Using our example of a bicycle with an 80-inch top gear, the Rohloff would reach Margaret’s 30-inch criteria in gear 4, and go as low as 15 inches in bottom gear! The hub is fitted as standard on the £1,880 Birdy Grey, the £2,000 Brompton- based SP and can be shoe-horned into most other bikes if your budget extends to that sort of thing.

“I have had three punctures on my Brompton since Christmas.The first in the front Marathon, the second in the rear Brompton tyre, prompting me to change it for a Marathon.The third was in the front Marathon again, causing me to regret spending on the rear tyre change. Just to make it worse, Mosquito Bikes fitted a 5/8in (16mm) Schwalbe 4a AV tube that is supposed to stretch to 13/8in (37mm). When it’s stretched that thin, how long will it last?
What BSI tests, if any, apply to kevlar-reinforced tyres? If there are none, what are the closest applicable to motorcycle tyres?”
Mike Hargaden, London
Punctures are a big problem for some people, under some conditions, while others hardly get to see a flat tyre these days. In general, any solution that prevents foreign bodies penetrating the tube (and there are many) will increase rolling resistance, because tough or springy extra layers don’t like to flex, as a tyre must.They obviously increase weight too, and extra weight in the tyre can result in a less sprightly ride and slower response, making the bike feel turgid and heavy. So, even when they work, it’s not all good news.
As for 16-inch (349mm) tyres, the A to B readers’ tyre survey (see A to B 40) suggests that the standard Brompton tyre punctures about every thousand miles, the ‘Green Flash’ kevlar-banded Brompton tyre a little more frequently, and the kevlar-banded Marathon about every 860 miles.This tends to back up my own observations, so taking weight, price and poor rolling resistance into account, I simply wouldn’t recommend kevlar tyres. It may well be that certain types of band perform better than others, but I have yet to see published research on the matter.
Puncture-proof, at a terrible cost, are the so-called ‘solid’ tyres.These may be just tolerable on a 26-inch wheel, but at 16-inch the high rolling resistance and ‘wooden’ feel make these things more trouble than they’re worth.The same goes for ‘solid’ foam inner tubes, about which the less said the better.
Raleigh extra-thick Puncture-Resistant inner tubes provide a good low-tech compromise, but these may no longer be available in small sizes. I fitted a pair to a Brompton two years ago and I’m still waiting for the tyres to deflate. Schwalbe uses a similar technique on its Marathon Plus tyre, which has a 5mm thick flexible india rubber belt under the tread. These tyres are heavy and only produced down to 20- inch (47x406mm), but a 349mm variant should be available soon. I am currently testing a pair of 20-inch examples and will release data in future issues.
Schwalbe Marathon Plus - the thick rubber band prevents penetration
Many proprietory tyre liners are available, but if wrongly fitted these can cause more trouble than they’re worth. As for the tube, Schwalbe does indeed offer a simplified line- up, with typically four or five similar tyres sharing the same tube. However, you should have been offered the 4AV, which is designed to stretch from 28mm to 37mm. I can find no record of the 16mm Schwalbe 4a, which sounds very tiny, and would be quite unsuitable for stretching to 37mm.
Motorcycles do, indeed, puncture less frequently than bicycles, but they also have a lot more power available to roll the tyres, which can thus be made a lot thicker. As minimum horsepower machines, bicycles will always require lightweight and thus vulnerable tyres.
FIRST PUBLISHED February 2005 Wessex Trains, Bike-in-a-Bag
Try as they might to look corporate and glossy, privatized railway companies have a fundamental ineptitude that makes them easy targets for mirth. Take for example, Wessex Trains, the scourge of Bogworthy Junction.
When dear grey Mr Major hit on the idea of privatizing the railways, his aim was to turn the clock back to the 1930s, a generally positive era for trains, although hardly a golden one. In those happy days before Hitler and post-war transport planners went and spoilt everything, the railways were split into four large regional companies, each one responsible for railway services and infrastructure: hotels, ferries, buses, a few air services, freight, parcels, pork pies, and so on. The system had its faults, but by and large it made money and provided rather well integrated transport. Had one been fortunate enough to catch a Great Western train from Paddington to Bogworthy Junction, for example, one would have found a Great Western branch line train providing the connection for Little Piddlington and Hampton Gusset. This well proven technique of making trains, buses and other vehicles connect with each other seems alien today, but it provided effortless transfers.
Come privatization, and forces in the Treasury and other departments engineered a rather different arrangement, where a multitude of intercity and regional train operators would contract to run services against each other. This had the transparent objective of making the industry more competitive (ignoring the fact that the railway was already engaged in a cut-throat battle with cars, planes, coaches and indeed bicycles), and the less transparent objective of isolating the minor and regional lines from their wealthier brethren, clearing the way for wholesale closures.
Busy Bogworthy became part of the lame duck Wales & West franchise, running the smaller Great Western lines at a substantial loss, whilst most of the trains actually stopping at Bogworthy were provided by the wealthy (but oddly, not very profitable) First Great Western.
Great Western had been briefed to ignore the local trains and experiment with its own buses, the general understanding being that local services would rapidly fail. Meanwhile,Wales & West was dismembered, the Bogworthy zone becoming part of Wessex Trains, a strange animal, neither clearly private nor state-owned, but heavily subsidised.
The awfulness of the ensuing decade is too frightful to record in detail. Suffice to say trains grew older and less reliable, arcane industry rules became more cumbersome and Byzantine, but traffic volumes grew, putting the creaking regional system under strain. Most Wessex services were now too busy to close, but the extra passengers were only increasing the problems.
In practice, Wessex, like most regional railway companies, has very little say in how and when its trains are run. Take for example the peak summer services from Bogworthy to Budmouth-on-Sea. With the normal two-coach trains often overwhelmed, Wessex decided to lease some ‘proper’ coaches and a pair of wheezing historic diesel locomotives, one at each end. The principle behind sending a train out with two engines – where Brunel et al might have considered one more than sufficient – was to cover for the all too frequent breakdowns, and make the train easier to reverse. Budmouth is blessed with a ‘run-round’ loop from the days when single engines were the norm, but following the absurd break-up of the industry, Wessex staff were no longer allowed to use it.
The mayor of Caster-bridgeshire meets his namesake, withdrawn from service weeks later
Thus, the oil-belching ‘heritage’ train duly rumbled back and forth to a somewhat hit-and-miss schedule until the Strategic Rail Authority or some such body (one is never quite sure) instructed Wessex to withdraw it. Unfortunately, this bombshell arrived after arrangements had been made to name one of the arthritic locomotives ‘Mayor of Casterbridgeshire’. In a wonderfully Doctor Beeching-esque moment, the mayors and other dignitaries had barely digested their chicken vol-au- vent and fromage surprise, before the locomotives and carriages were quietly withdrawn, this less satisfactory twist being the subject of an ongoing news embargo.
One final ‘Santa Special’ was run in December, apparently in defiance of the SRA, but Wessex has no spare rolling stock to handle the 2005 traffic peak, and no clear idea how to get around the problem.
…the dignitaries had barely digested their vol-au-vent before the locomotives and coaches were withdrawn…
One would have more sympathy for the management team, where it not so adept at shooting itself in the corporate foot. At Bogworthy, access to two of the three platforms is by way of a narrow and rather steep footbridge. In theory (and in practice, not so long ago) staff were available from 6.30am to 10pm to assist disabled passengers over a level railway crossing. But under the Wessex regime, morale has fallen to such an extent that staff are frequently absent. When cross-examined about this by a rightly indignant wheelchair-bound visitor, the regional manager suggested proceeding to the next station down the line, and catching another train back. But as even the station cat could have told them, this time-consuming manoeuvre would merely bring the customer back to Platform Three, at the bottom of the same steps.
Bicycle carriage policy has deteriorated too. Bicycles were already banned on busy commuter trains into major cities, but Wessex tried to extend the ban to cover most of its peak-hour trains, some of which had plenty of space for bikes. After a few months, the company backed down and rescinded the bike ban, then attempted to mitigate this PR disaster by encouraging commuters to purchase a ‘Bike-in-a-Bag’ folding bike. But as even the importers of the machine would have to admit, the Bike-in-a-Bag is hardly designed for daily use, and – more crucially for Wessex – it makes a large and unwieldy folded package on the train.
At Bogworthy, the perfectly adequate cycle racks were secure and undercover on Platform One, but without so much as a by your leave, Wessex decided to scrap them and put new ones ‘somewhere more convenient’. Needless to say, the old racks went, but nothing arrived, leaving no cycle parking at all.
Staff were then told to expect smart new uniforms. When they arrived, they were two sizes too big. Replacements are now lost in the system.
None of this would matter too much if the trains ran on time, but they don’t. A quick survey reveals only 59% running with what one might describe as Brunellian precision – the remainder running up to 36 minutes late.
The general impression is of an industry in deep crisis. Costs and confusion have run out of control, but management has lost the ability to consult, to plan for the future, or make the simplest day-to-day decisions. For regional franchisees like Wessex, even basic procedures, such as clearing a few nettles to make way for a car park extension, can cost thousands of pounds, months of negotiation, and planning on a military scale. This is not entirely the company’s fault, of course – it’s just that the industry is unworkable.
The real tragedy of this gentle rural farce is that the wolves are already gathering at the door. New Labour is no friend of the railway industry and is now so deeply distrusted in the shires that it would have little to lose by backing closure plans. A substantial majority for Labour at the next election could mean a round of rural rail closures, forcing more people onto the roads, just as the twin futurist nightmares of declining oil production and global warming make their presence felt.
…the real tragedy of this gentle rural farce is that the wolves are already at the door.
And why does one suddenly feel tempted to take global meltdown seriously? Rather disturbingly, it seems that Lord Oxburgh, chairman of Shell, is riding a Brompton to work and making apocalyptic predictions about climate change. At home, we are told, he has persuaded his wife and son to ride bicycles too, keeping a 60mpg diesel car in the garage just for ‘trips to the supermarket’. Could he know something we don’t?
But all may not be lost. Younger readers may need reminding that Jim McGurn once ran a cycle publishing empire that over-stretched itself, resulting in ignominious receivership and lost nest-eggs for hundreds of innocent backers.
McGurn went on to pilot a small-scale bicycle try-out concession at the doomed Earth Centre near Doncaster, until that too went into administration on New Year’s Eve 2004. Not Jim’s fault, of course, but one begins to sense a pattern. Our hero now proposes to bounce back with Bikeland, a £33 million Disney-style cycling theme park to be based in Derby.
One hates to be sceptical, but £33 million of lottery money would fund an awful lot of cycle paths, safe Toucan crossings, secure cycle parking, and other practical day-to-day measures to get people out of their cars and onto their bikes. One suspects that if the Lottery Commission is misguided enough to support it, Bikeland will go the same way as all the other grand projects. In any event, it wouldn’t open before 2008.
Here at A to B we can be a bit sceptical about government schemes to boost cycling. Don’t forget, this is the same bunch that imposed on- the-spot fines on elderly ladies riding sedately on the pavement, but wouldn’t fund the cycle facilities to keep riders safe; that built more and bigger roads, when they claimed to be reversing the trend, painted speed cameras bright yellow, so motorists could avoid the fines, and promised to quadruple cycling, but oversaw the biggest decline in cycle use ever recorded. Why would we take any notice of a government scheme?
We should have noticed this one. Last year, the Chancellor announced that ‘green’ travel to work initiatives would be allowable as tax-free incentives for company employees, provided certain conditions were observed.The list of qualifying ‘Travel Plans’ included free or subsidised works buses, occasional lunchtime use of said bus, subsidies paid by employers to public bus services, season tickets, up to six cyclists’ breakfasts a year (big deal), workplace cycle parking, and – more crucially – bicycles and equipment.
Initial take-up was slow, because the conditions sounded complex, and few people had looked into the small-print of what appeared to be a routine announcement about bus subsidies. But things were moving, and soon Halfords, Giant, Specialized and Trek had coalesced around an agency called Booost – already providing computer equipment in a similar scheme. Under the guidance of the Association of Cycle Traders, the bicycle bit was soon up and running, and the early participants were joined by Gary Fisher.
All very cosy. In theory anyone could set up a scheme, but these big multi-national companies had made all the running, and they were understandably less than willing to share this profitable new business with other cycle manufacturers or small retailers.
…the scheme is for the mass-market, and the mass-market is happy with Halfords bikes…
Booost blames government demands that tax payers’ money should not be spent on BMX and childrens’ bikes, forcing it (rather oddly) to stick with the biggest manufacturers and retailers. Somehow, this bias towards big business all sounds very New Labour. Booost reassured us that bikes could be bought through independent cycle retailers too, and the Association of Cycle Traders has been skirmishing with Halfords to bring this about. It claims that ‘several hundred’ bike shops have expressed an interest, but to date, few have made sales.
In theory, Halfords can source bikes from any manufacturer, but in practice… well, you get the picture. According to a Halfords representative, ‘The scheme is for the mass market, and the mass market is happy with Halfords bikes.’ Well, maybe, but mass market bikes are not necessarily the best commuter machines. More importantly, folding bikes are hardly represented at all.
Trek and Specialized market reasonable Dahon-based folders, and the Giant Halfway is a neat little bike, but there’s not much else. Dahon bikes are sold in some Halfords branches, and should thus be admissible, but the really specialised folders, such as Bike Friday, Birdy, and particularly, Brompton, are excluded. Halfords is not authorised to sell any of these, and although the company will endeavour to source one by fair means or foul, it is not in a position to honour the warranty or provide servicing.With the notable exception of the Giant Lafree, electric bikes are excluded too. Meanwhile, Brompton has tried hard to get on the scheme, but been repeatedly rebuffed.
How does it Work?
Like all government schemes, it’s a bit complicated.The employer agrees to lease a number of bicycles (plus safety equipment, accessories and arguably even trailers – there’s no limit) chosen by its employees.When the purchases are made, the employer claims back the VAT, effectively knocking 17.5% off the purchase price, with the saving (hopefully) being passed to the employee.The bike is now owned by the employer, and loaned to the employee for a set period; the interest-free loan payments are deducted at source, effectively making the purchase free of income tax and National Insurance too. After a set period, the employee can purchase the bicycle for a nominal ‘fair market value’, and it becomes their property. Payments can be made over any period, but twelve months is typical – this interest-free loan being a useful bonus in itself.
Brompton L6 £322
Got that? The details of individual schemes vary, and the tax band of the participant has an effect too, so it’s hard to be precise about the savings involved, but most tax payers would expect to pay around half of the normal retail price – higher rate tax payers even less. Obviously, the more you earn, and the more expensive your cycling tastes, the greater the advantage.
The only loser is the bicycle retailer, obliged to pay a small administration fee to Booost.The employer saves 12.8% in National Insurance contributions, which can be passed on or used to cover administration costs. Of course, participating employers also get a useful recruitment incentive and happier, healthier employees.
According to the Inland Revenue, the bicycles can, like company cars, be used for leisure purposes, provided they are used ‘mainly for travelling to and from work’.And as with any other bicycle, if the machines are used for work-related journeys (not commuting, unfortunately), employers can also pay employees up to 20p per mile free of tax to cover depreciation.
Where’s the Catch?
At the moment there are a whole set of problems. Halfords says it will do business with small employers, but Booost is generally only willing to talk if you’re in the market for hundreds of bikes.The perception for many smaller employers and cycle retailers is that the whole thing is just too much trouble.
Birdy Red £490
Fortunately, there’s no need to deal with Booost or Halfords if you don’t want to. Frustrated with the current schemes, independent cycle retailers are setting up their own. One of the first is the ‘CycleScheme’, launched by Avon Valley Cyclery of Bath. Avon is a key supplier of folding bikes, including Moulton, Dahon, Brompton, Airnimal and Birdy.The company also specialises in racing and mountain bikes from Giant, Marin, Gary Fisher, LeMond and Klein.Thus CycleScheme will cover some classic commuters, plus the sort of rare and specialist bicycles that you really wouldn’t want delivered to the back door of your local Halfords. And despite being a division of a retail outlet, CycleScheme claims to work with other independent shops – the intention is to rival the national coverage of Booost itself.
Larger employers are starting to do their own thing too. Company ‘A’ with 350 employees was rejected as too small by Booost, but set up its own scheme, negotiating discounts with individual cycle shops, which get a nice simple cash sale. Company ‘A’ also saved on leasing fees by arranging a short 3 month lease period and paying cash for the bikes. In the first month, 20 employees have signed up.
The Future
Unless the government changes its mind and withdraws the bike scheme, the impact on top-end bicycle sales will be huge. Bike to work programmes are particularly well suited to folding bikes, because employers are also allowed to provide tax-friendly loans to cover season tickets up to a £5,000 ceiling. So the means exists to subsidise every part of an employee’s rail/cycle commute, from the bicycle and accessories, through the train fare, to cycle storage at work, and even the occasional breakfast!

With most British products now designed and made elsewhere (albeit by British designers very often), we sometimes have to be reminded that we once built rather good vehicles. Every nation could unearth a few classics, but our little islands have produced a whole encyclopedia: beautiful ocean liners, graceful steam engines, grand cars, aircraft, motorcycles and of course buses.The theory behind Britain’s long love affair with the double-decker bus is that our narrow city streets made it necessary to build upwards. Perhaps, although the same could be said for any number of European cities. More likely, we just enjoyed being different.
How did London’s Routemaster bus become such an enduring icon – a symbol of the capital, recognised the world over? Although comparatively recent, the design successfully combined old and new in an alluringly British way: the open rear platform and steep stairs had their origins in the horse-drawn omnibuses of the Victorian era, but the running gear and general space-efficiency of the machine were right up to date. In terms of overall dimensions versus passenger capacity, it was a remarkable bit of packaging that may never be surpassed, and although designed and built in the 1950s and ‘60s, the Routemaster – like all the best icons – remains a strangely timeless machine.
RM1, the Routemaster prototype, was built at London Transport’s Chiswick garage in 1954, and was followed by a further three as the details were refined. In 1956 an order was placed for 850 production machines, the mechanical bits being assembled at lorry maker AEC’s factory in Southall, and the bodywork at the company’s nearby Park Royal plant. Buses gradually came into service from June 1959.
…it was a remarkable bit of packaging that may never be surpassed…
Several variants were made over the years, but the classic Routemaster was bright red (naturally), 27′ 6″ long, eight feet wide and just over fourteen feet tall. Access was via an open platform at the rear kerbside, leading to a flight of steeply curved stairs to the top deck, or a single step up to the bottom deck. Early examples had 64 seats, but from 1965, an extra centre section was added to create the RML; a shade over 30 feet long, with 72 seats.
The open platform was a bonus in congested central London, but the free and easy access also made them dangerous for cyclists nipping up the inside
The Routemaster may look timeless, but beneath the surface, the design was seriously cutting edge. Previous double-deckers had been built of steel and wood around a substantial steel chassis.They could be prohibitively heavy, and the Routemaster’s predecessor, the RT, was limited to 56 seats to keep the weight within limits.
Instead, the Routemaster was built around a strong, but lightweight ‘monocoque’ aluminium body, doing away with the heavy chassis altogether, at a time when such technology was considered adventurous in the car world. The AEC 115hp engine, 4- speed gearbox and suspension were bolted to subframes under the body. At 73/4 tons, the Routemaster was incredibly light for its day, and remains smaller, some two tons lighter, and more economical than similar modern buses.
The best bit for large and small boys alike was the driver’s cab. Once again, there were Edwardian echoes, with the driver sitting in stately isolation up front, to the right of the engine. But beneath the surface, the cab bristled with innovation – independent front suspension, power steering, power-assisted hydraulic brakes, and a fully automatic gearbox. All very conventional today, but state-of-the-art for the 1950s.
Rise & Fall
Numerous design changes were made over the years. Most were very minor, but a Leyland diesel engine was tried for a while, and a faster RMC coach derivative with fewer seats and electrically-operated doors, was built in quite large numbers to race rather incongruously in and out of London, notably to Heathrow Airport.
Altogether, more than 2,800 Routemasters were produced, mainly for use in London, but with a small number going elsewhere.The last of the series of development prototypes, unveiled in 1966, was as strikingly modern as RM1, with front platform doors and a rear engine, but for political and practical reasons, the design was never put into production.Another option put forward by the design team was to put the engine under the front stairs, a brilliant bit of packaging, but nothing more was heard of the idea.
…the buses were just too cost-effective to be withdrawn en masse…
From then, as with so much of British innovation, the story was one of gradual decline, although the Routemaster, designed for a life of twenty years, was to outlive its contemporaries by a considerable margin.
Withdrawals began in the late 1970s, but the buses were just too practical and cost-effective to be withdrawn en masse. Newer one-man- operated buses saved on manpower, but caused traffic delays and were unable to dispense change or cheerful cockney travel advice like the Routemaster conductors. Although losing ground in the suburbs, the old buses clung tenaciously to the congested inner urban routes.
In the following thirty years, some 1,500 Routemasters were scrapped, but many cast-offs found a new lease of life with provincial bus companies, particularly in the cut- throat post-deregulation world, where the space- and fuel-efficiency of the design often outclassed newer machines.
In London, Routemasters were even being upgraded, 600 of them receiving new Cummins and Iveco diesel engines in the early 1990s. Privatization came and went, and still the Routemasters kept rolling. Confidence was boosted with yet another refurbishment programme between 2001 and 2004, when mayor Ken Livingstone reiterated that the Routemaster was an essential part of the London scene.There was an anniversary party in 2004, featuring numerous early examples of the marque, including RM1, still in revenue service after an astonishing 50 years. But a few months later, the mood suddenly changed, and Transport for London announced that the last buses would be withdrawn and sold by the end of 2005.
Why? It seems that buses with open platforms are becoming increasingly difficult to insure in this litigious age, and the Routemaster’s high platform was never, ever going to be wheelchair accessible. Ironically, this most space-efficient of vehicles is being replaced with so-called ‘bendy buses’ – cumbersome articulated single-deckers that occupy a great deal more of London’s precious road space.
Now past its half-century, there’s no doubt the Routemaster needs updating. As one Londoner puts it, ‘Don’t get too misty-eyed: they’re good fun if you’re fit, childless and enjoy excitement and (very) cool breezes. Everyone else is better off on the new buses.’
Blake Cotterill’s updated Routemaster design
Like most older vehicles, the Routemaster is hardly folding bike-friendly either.The tiny luggage space under the stairs is small and often jealously guarded by the conductor. Modern low-floor designs, most of which incorporate a spacious wheelchair/buggy area, are much more practical in this respect.
The updated Routemaster would be broadly similar in layout, but front-wheel drive
Could a new Routemaster still emerge? One interesting proposal is the Q-Master, a strong, low-floor Routemaster update, but as with the railways (see High Speed Train, A to B 27) www.atob.org.uk 11 A to B 46 the funding mechanisms and political will just don’t seem to be there any more. But a generation of young British designers is refusing to go quietly. Blake Cotterill, a student at Coventry University, has proposed an updated driver-only-operated Routemaster with front doors and a host of new technologies.This ‘hybrid’ diesel/electric machine would feature an internal combustion engine in the classic front position to aid accessibility, but the engine would drive the front wheels, giving a low floor throughout.Acceleration would be boosted by an electric motor fed from a fuel cell and/or batteries, providing regenerative braking and – once again – class-leading fuel economy.
Routemasters are set to disappear completely in the next few months unless a ‘heritage route’ reprieve is announced. At the time of writing (January 2005) the buses were still operating on seven routes:
No 13 Aldwych – Golders Green No 14 Putney – Tottenham Court Road No 19 Finsbury Park – Battersea Bridge No 22 Putney – Piccadilly Circus No 36 Queen’s Park – New Cross No 38 Clapton Ponds – Victoria No 159 Streatham – Marble Arch
You can help save the Routemaster.There’s plenty of information at www.routemaster.org.uk or www.savetheroutemaster.moonfruit.com where more than 10,000 people have signed the online petition to date. Meanwhile, do take a last ride (preferably without a folding bike).
“ What Walkmans did for music, folding bicycles may be poised to do for cycling. The bikes… collapse into a bundle small enough to be carried on a bus, stowed under a desk or packed into a suitcase. They are common in Europe, Japan and China, but have been slow to catch on in this country…
‘There are times when a full-sized bike doesn’t work,’ said Eric Sundin, president of Folding Bikes West… He’s guessing that in five years, sales of folding bikes will be huge, and transit projects, such as the Monorail and Sound Transit’s light rail, may make them more attractive to commuters… Among the young and fashion-conscious, the ingenious contraptions have begun to be touted as accessories to the chic urban lifestyle. But their true path to fame and fortune may lie with commuters.
With fuel costs hovering around $2 [£1.06] a gallon, folding bikes can be an inexpensive cog in the wheel of ‘multimodal’ transportation, in which people may drive part-way to work then switch to a bike, or ride to a transit station and then take a train. Bob Lovejoy, 51, owns a British-made Brompton bike and can hardly wait for a light-rail line to open near his home so he can use his bike part-way to get to his job as a computer systems administrator. ‘It’s not what you’d want if you were going to ride 50 miles. But for going five to seven miles, or riding to a transit station, it’s perfect,’ he says. ‘You just fold it up when you get on, and unfold it when you get off.’”
For months now weve been terribly short of space, but at last weve progressed our master plan to add extra pages – four this time, but there may be more in 2005. More space means more expense, but were hoping to keep the cover price unchanged for the time being, and were grateful to our past and present advertisers whos continued support has made this possible.A very jolly and prosperous Christmas to the cycle shops and manufacturers big and small that have backed us over the years, and to each and every subscriber. In such a specialist area, and with a relatively small subscription base, individuals really do count Thank you! Oops, almost forgot… bike of the month. Were tempted to opt for the BionX. Its certainly one of the most unusual bicycles weve seen.
Oh dear, the Bickerton lives on. A long aluminium tube surmounted by some wobbly looking handlebars – it’s all horribly familiar. Actually, the iXi looks a lot more elegant than any Bickerton ever was. But I ask you, belt drive! I have memories of an early belt-drive Birdy of almost legendary inefficiency. ‘Like cycling through treacle,’ was one of the kinder verdicts on this ‘clean, grease-free’ system. And why does the iXi split in half instead of folding down properly? The ‘impact resistant’ drinks holder looks very swish, but will your tea be impact resistant too? The in-frame storage could be handy if you need to carry a banana. And here’s the punchline: £999 for the split-apart version, with not much change from £1,200 if you specify the optional lights, luggage, mudguards and key fob. Still, the website is very nice.
VERDICT – MISS
Gary Lovell
…carefully thought out, but they used all the wrong thoughts…
For – step-thru frame, carrying handle and front disk brake (no rim wear). Against – heavy aluminium frame with no rear suspension and 100 psi balloon tyres, which must give a harsh bumpy ride.The bike does not fold, but separates (eventually) into too many unmanageable bits. And quick releases everywhere mean any of these parts can be stolen by passing criminals.
The oil-free belt drive is nice, but this system will give no positive feel. It needs a chain fully enclosed in a lightweight chaincase (this would be possible, because the rear end does not fold).There aren’t enough gears either (five or six hub gears should be the minimum), and the back-pedalling coaster brake is not up to busy stop-go urban commuter traffic in my opinion.
Surprisingly on such an expensive bike, there are no mudguards or lights as standard, and the basket system – although adequate – seems to have to stay on the bike once fitted. It looks as though it would seriously inhibit the separation of the bike for storage. The price is outrageous – £1,130 as I would equip it. I would expect to pay nearer £380 for this sort of machine.
This bike has been very carefully thought out, but they used all the wrong thoughts. I’m confused as to what it is actually for. I can only think it is suitable as a very short-haul shopping bike.

Cyclists with busy schedules and a folding bike can get from Leeds to most parts of the Yorkshire Dales National Park, as there is a weekly bus service as far as Hawes in Wensleydale.The 804 departs from Leeds Bus Station at 9.40 on a Sunday morning.The fare is £3.60 single, but a ‘Day Rover’ return ticket costs only £4. However, do check the times and fares before you go! Here’s an account of my recent trip.
The bus was a single-decker and about two-thirds full.The other passengers were mainly hikers and those who noticed the Brompton were delighted with the ease of folding and carrying. As a Brompton owner you get many opportunities to show off, as you demonstrate the 12-second fold. Even the T5 touring version with dynamo lights, a rack, saddlebag, tools and puncture repair kit only weighs around 13.6kg (30lb).
With a fully-loaded front touring pannier and a 50 litre rucksack on the rear carrier it weighs a bit more.When the bike is folded and carried (or wheeled along) using your right arm, you can carry a touring pannier in your left hand and the rucksack on your back.When riding, straps secure the rucksack to the underside of the saddle and the top of the rear carrier. I have no trouble fitting all the gear needed for a cycle-camping tour into the front pannier and the rucksack.
The advantage of a rucksack as cycle luggage on a folding bike, over conventional panniers on a traditional touring cycle, are that if desired, you can roam off over the hills and footpaths with the rucksack whilst the bike is locked up safely back at the campsite or hostel. A decent-sized rucksack fits neatly between saddle and rear carrier on the Brompton.
…a fine feast, with more pudding and custard…Bakewell tart this time…
I got off the bus in Grassington and had a pleasant breakfast at the Cobblestones Café. After buying some provisions in the shops I then cycled on to Kettlewell; it’s about six miles and very pleasant on the old back road. Stopping to talk to some walkers resting on a convenient wooden bench we had a chat about the wonders of the Dales.
At Kettlewell I registered in the Youth Hostel, which was almost empty. After a delicious evening meal (followed by a Portly-ish sponge pudding and custard for afters!), I rode up onto the moors on the Leyburn road.There are two very steep 1:4 hills, which were fun, but hair-raising, to descend. I came across some friends on my return who were in Kettlewell for the day and had arrived by car, with two small toddlers.We chatted until night began to fall, when I locked my trusty folder in the shed next to the hostel and waved goodbye to my friends. Back inside, I found a fellow resident, so we retired to the friendly King’s Head for a drink and a game of dominoes.
Next day I walked up Great Whernside in bright sunshine and got soaked to the skin when the weather changed – I had to navigate off the hill through the mist and clouds with a compass.What a fine adventure! The following day I climbed Buckden Pike. Two sheepdogs, one a young puppy, left their owner building a wall and accompanied me up the hill. It was very windy and cold, but sunny and warm in the shelter of a drystone wall. I returned to the hostel with the aid of a head torch as night was falling and had a fine feast, with more pudding and custard… Bakewell tart this time.
On the third day I rode back to Grassington on a fine crisp spring morning, and on to Skipton, where the market was in full swing. After an interesting look round I bought some shoes, some fine cheeses and pies and a Derby Tweed jacket! My loaded Brompton was safe, locked up in a largely crime-free Skipton and so I went to look round the antiques and bric-a-brac fair in the Town Hall.
My stay eventually ran its course and I caught the hourly bus back to Leeds – a very reasonable off-peak fare of only £1.70.When I first returned to bus travel after scrapping my car I was pleasantly surprised to discover how friendly other passengers usually are. As a car driver one frequently experiences other drivers as ‘competitors’ trying to overtake, even when it is not safe, and a continual struggle for road space takes place.The road was busy with traffic and I was glad to be ‘chauffeur driven’.The bus driver deals with all the stresses of the journey. Sometimes it’s fun being a cyclist!
A number of special buses (including one with a trailer for conventional bikes) run into the Yorkshire Dales from Leeds,York and elsewhere on summer Saturdays, Sundays and Bank Holidays.There’s also a basic winter service. Special offers include a £1 discount at Malham Youth Hostel (look after t’pennies, lad’) on production of your bus ticket. Full details of the 2005 services can be found at www.dalesbus.org
One of the most adaptable trailers is the 5-in-1 from Orbit Cycles, here in freight mode
Bicycles can carry astonishing loads, but there’s a limit to the amount you can pile on the bicycle itself.That’s where trailers come in. Living without a car, we’d be severely disadvantaged without a bike trailer – they are wonderful things. Alexander usually trailer- bikes to school these days, but in a typical week, our trailer still ferries heavy loads to the local tip, recycling to the bottle bank, collects shopping from the town, meets rail passengers carrying a spare folder, and numerous other tasks. It’s hard to say how many miles it does, but it’s probably two-thirds of our total electric bike mileage.We use a two-wheeled trailer exclusively – they’re easier to hitch and unhitch than a single-wheeler, carry more and can be wiggled through surprisingly small gaps.
Which trailer?
We’re great advocates of child trailers for all purposes, partly because they keep sleepy motorists awake. As a general rule, cars will give a child trailer a wide berth – we’ve certainly had fewer ‘incidents’ with a trailer attached than riding without.
The best all-round designs fold quickly, carry two children plus a couple of shopping bags, or 40 to 50kg of freight. Many such trailers exist.We’re still using a US-made Winchester of 1997 vintage (better known today as the Kool Stop Original Mark 2). These cost nearly £300, but there are a number of Far Eastern alternatives for less than £100.The cheaper trailers can be heavy, but if you don’t expect to lift it, that may not matter.There are an increasing number of freight-specific and dog-specific trailers available too – worth considering if you only expect to use a trailer for one task, but a child-trailer does most things quite well.
For public transport, light weight and compact folded size are the primary requirements. By far the best is the little Burley Solo which used to weigh just 7.3kg (16lb), but is probably a little heavier in its new guise (tinted windows, etc).The Solo is small enough and light enough to take just about anywhere and has no real competition, but for buses, in particular, do use a bag or cover. Bus drivers and railway guards can refuse to carry trailers if they think they might be a nuisance. Enough already – for a full list of all the trailers on the UK market, see our web site www.atob.org.uk
Common sense
The use of trailers with motor vehicles is heavily regulated, but surprisingly, cyclists are free to pull any weight on one, two… even a train of trailers, provided they are reasonably sensible about it. Common sense suggests a few basic rules.
It stands to reason that the towing bicycle should be in good condition. Brakes must be powerful, but not overly fierce, and the wheel, steering and suspension bearings must be free of play (looseness to non-engineers).The extra stress from a laden trailer can turn an old, but apparently rideable, bicycle into a wobbly jelly, so do check the machine over carefully.
Power assistance makes a great difference to the viability of pulling big loads in hilly areas.With muscle power alone, it’s deceptively easy to tow your own weight or more on the flat, but the slightest gradient will knock your speed back to a walking pace. Even limited power assistance can make a big difference – for years we used a Zap friction- drive kit to help pull big loads, and these days our heaviest trailer-fulls (primarily A to B magazines from the printers and to the Post Office) are shifted behind our Giant Lafree. This isn’t the most powerful electric bike around, but for towing you need slogging ability rather than outright performance.The same applies to muscles and indeed diesel engines.
Many types of tow-hitch exist, but not all are up to dealing with heavy loads.The least satisfactory design for heavy hauling is the seat post hitch, and as a general rule, the higher the connection, the worse it gets. As the trailer pulls back and forth and from side to side, this type will try its hardest to push you off the bike.We’ve towed unlikely weights with the wrong type of hitch fitted in the wrong place, but this is something of an acquired art.
In our experience, a hitch that mounts on, or close to the rear axle is the best kind, and our favourite is the Burley ‘alternative hitch’, available in quick-release or hub gear variants.These are quick and easy to swap from bike to bike, rigid, and easy to use. Other good hitches exist, such as the Weber, but look for something that allows movement in all planes without flexing. Some use a spring or flexible tube, which can work well with light loads, but may oscillate or ‘snake’ from side to side at speed with heavier loads. As with a car, you generally don’t discover that your ‘outfit’ is prone to snaking until you’re travelling fast enough for it to be a problem. If oscillation gets out of hand, particularly on a corner or while braking, the towing vehicle can be flipped off the road.
The best way to prevent calamities is to load heavy objects as low down, and as close to the centre of the trailer as possible – preferably just in front of the wheels.The idea is to have a small percentage of the trailer load supported by the rear of the bike, which helps to improve adhesion when cornering or braking.Too much weight may cause the tow-hitch to bend or flex, which can start the trailer snaking.Too little – or worse still, negative weight (a load behind the trailer axle) – may cause the rear wheel of the bicycle to leave the ground. In motoring terms, the general rule is to put 10% of the trailer weight on the tow hitch, and that sort of ratio is about right for a bicycle trailer too.
Another cause of instability is a long load. Most trailers will safely carry 40kg packed tightly in the middle of the vehicle, but try towing 40kg as a pile of three-metre timbers, and most bike trailers will become very unstable. If you intend to carry long loads (such as a canoe) on a regular basis, you’ll need a trailer with wheels further back than normal and a very rigid hitch – this combination will put more weight on the back of the bicycle, which is inconvenient, but generally more stable.
…a 33kg payload – two smallish children or quite a hefty supermarket shop…
Maximum weight
Our personal favourite is the Burley alternative hitch.The ball-bearing allows a Brompton rear frame to rotate into the parked position, without removing the trailer.
For cars, the safe maximum weight for an unbraked trailer is considered to be half the weight of the towing vehicle, and for most purposes this is a useful guide to the weight a bicycle can tow in safety. If we take a bicycle and rider weighing 90kg, the total trailer weight should be kept below 45kg. Assuming a trailer weight of 12kg, that leaves us with a 33kg payload – two smallish children or quite a hefty supermarket shop.With a trailing load of half the rider/bike weight, you should barely notice the trailer is there, provided you take account of the greater stopping distance, width and lack of acceleration when pulling out into traffic.
If you can afford it, the Weber is the Rolls Royce of cycle trailer hitches
We regularly tow a lot more with our long-suffering Winchester – up to around the same weight as the rider and bike – and with a bit of care, anyone can do the same.With a trailing load of 90kg, you need to read the road with some care. Riding uphill will always improve stability, because the tow-hitch is pulled straight and rigid.Without power-assistance, hill-climbing can be painfully slow, but you’ll get there in the end with the right gearing.
Going downhill or braking (worst of all, both) is more complicated, because now the trailer is trying its hardest to overtake, and if over weight or poorly balanced, it may begin to oscillate. Fortunately, you’ve put the load just forward of the axle (you did remember to do this, didn’t you?), and this carefully positioned load allows you to make heavier rear brake applications without skidding. By contrast, the front brake should be used with real caution, because a front brake application will take weight off the back wheel. Similarly, keep your bottom firmly rooted in the saddle to put your weight over that crucial tyre contact patch.
…Children should be…instructed not to stand up and wave at passers by…
As a general guide, loads of 50% to 100% of the bike/rider are permissible with care, but beyond that, you’re on your own. In theory, a bicycle trailer can be fitted with over-run brakes just like a large car trailer. This would make heavy loads safer, but we’d still advise keeping gross weight below that of the rider and bike.
Finally, when you pull up at journey’s end in front of an appreciative crowd, do remember that the load may have shifted, turning a positive towbar weight into a negative one.This is fine until you hop off, causing the rear of the bicycle to leap up and everything to fall into a heap.
Cornering
We’d usually have the cover on, of course! Here the Winchester is carrying 900 straps yourself magazines, a gross weight of over 90kg. OK with care
Trailer suspension doesn’t need to be sophisticated. Our Winchester axle pivots against provided the occupants don’t find the a pair of bunjee cords
The Cateye LD600 is powerful, but slim enough to be bolted permanently to a folding trailer frame
As most bicycle trailers are designed for the litigious US market, manufacturer’s advice can sound extremely cautious.Take no notice – in many years of doing stupid things with over-loaded trailers, we’ve never, ever so much as lifted a wheel on a corner. Obviously common sense plays a role here. Avoid clipping kerbs with the inside wheel whilst cornering hard, in fact, avoid bumps generally. Children should be strapped in, or at least instructed not to stand up and wave at passers by. As roll-overs are rare, the primary purpose of a child safety harness is to keep the occupants still, making the trailer (and children) easier to handle. Do the same with freight – we use a pair of small 25mm ratchet straps, designed for car roof-rack or motorcycle loads. Bind everything down firmly, because if it can move, it will fall over or blow off at speed. Always check the and recheck after a mile or two if going any distance.You are entirely responsible for the load, and despite the lack of cycle trailer legislation, if the police really want a conviction, they can draw on a number of archaic laws from the days when penny-farthings frightened the horses.
…even the best trailers come with nasty cheap tyres that attract thorns like magnets…
If you’re not familiar with trailers, it’s worth practising riding techniques before venturing out, especially with children on board. Road positioning will be slightly different to normal, and you’ll need a lot more room to clear kerbs and posts.Try riding with a critical companion behind to give a running commentary. As a general rule, a well made and properly loaded trailer will do anything the towing bike can do in perfect safety.
Bumps & Rebounds
Cyclists are hard-wired to avoid pot-holes, or lift their weight out of the saddle if a bump is unavoidable. Believe it or not, it wasn’t until Alexander was old enough to complain that we realised the trailer occupant was unable to see the bump and thus unable to brace himself.We made life easier by fitting suspension – the previously rigid Winchester axle now pivoting against the spring force of a pair of bungee cords. Although rather crude, this system has excellent anti-roll characteristics (‘proper’ independent suspension would allow the trailer to lean outwards when cornering) and gives plenty of suspension movement. Manufacturers please take note and listen to what children are saying.The same applies to dumb loads. Carry a laptop in an unsuspended bicycle trailer and you’re asking for trouble. Place frail items on cushions, and lower the tyre pressures…
Another lesson we took years to absorb is that very light trailers require very little tyre pressure. Forget what it says on the side of the tyre – choose a pressure that will allow the tyres to absorb the worst bumps without going so low that the trailer begins to ‘wallow’ or becomes hard to pull. For a very small child, you may be looking at a pressure too low to register on the gauge. If you’re carrying gran home from the pub, you’ll need maximum and a bit more. And do try to remember just how boring a long trailer ride can be. As a cyclist, you can see over hedges and round corners, but the occupant of the trailer sees nothing but wheels passing by, which can become tedious very quickly. Alexander can survive a maximum of about an hour and a half without a break. A radio or cassette player works wonders, but don’t overdo the endurance thing.
One final point – even the best trailers come with cheap nasty tyres that attract thorns like magnets. Punctures are much easier to deal with on a stub axle (the tyre can be slipped straight off), but it’s still worth fitting decent hard-wearing tyres. As a last resort, a lightly loaded trailer can be ridden for miles with a flat tyre, ride too harsh.
Safety equipment
You may feel strongly to the contrary, but we’ve never used trailer flags.The annoying fiddly bits take ages to put together, the shaft whips about, threatening to thwack pedestrians, and there’s quite an increase in drag. Our general view is that flags are more trouble than they’re worth. On the other hand, we’re very strict about reflectors and lights – a trailer should have two well spaced reflectors and at least one powerful LED rear light on the offside (away from the kerb).The slim and ultra-bright Cateye LD600 is perfect. Twin lights are better, of course, and it’s quite legal (and probably advisable) to use flashing LEDs.There’s a theory that twin lights could be confused with the lights of a car much further away, but this may be a modern myth. Use light(s) at dusk, during heavy rain and any other time you feel vulnerable. If you habitually tow a large trailer after dark, there’s a good argument for fitting a front-facing white LED on the offside too.
Which bike?
You can tow almost any sort of trailer with almost any sort of bike, but some combinations can be hard work.When we had nothing more suitable, we pulled our big heavy home-made trailer with an old (and poorly braked) Brompton L3, using a hitch right under the saddle. No one ever fell off, but hills were hard work.These days, we generally use the Giant Lafree for heavier work, but it very much depends where you live. An electric-assist bike makes hills and road junctions a lot easier, and of course, safer.
The message from Brompton is one of incremental changes, some small, but others of real importance, or at least, interesting enough to report.Weight is unchanged, as is price, but there have been subtle improvements. To recap briefly, the Brompton has been around since the late 1980s. Although never officially designated as such, early hand-built bike are usually called Mark 1s, the 1991 – 1999 bikes the Mark 2 and more recent machines Mark 3.The post-1999 Mark 3 looked much like its forbears, but was rebuilt almost from scratch, resulting in a lighter, faster and more rugged machine.The only big change since has been from Sturmey Archer 3- or 5-speed hubs to a SRAM 3-speed with the option of a Brompton 2-speed derailleur, giving six gears.
Rear frame
History has come full circle. Five years ago, Sturmey Archer was driven into bankruptcy, later re-emerged as part of the Sunrace group, which is now manufacturing a full range of hubs from a factory in Taiwan.Wary of being tied to SRAM alone, Brompton has redesigned the rear frame of its bikes to accept either type of hub gear. In practice, this means that 3-speed bikes will be equipped with Sturmey Archer hubs, but the 6-speed will continue to use SRAM, because the Sturmey Archer is unable to accommodate the two-speed sprocket assembly used on the 6-speed. Still with us?
These changes raise several questions and answers. If you buy a 3-speed, you will no longer be able to upgrade to a 6-speed without buying a SRAM hub. On the other hand, you can now upgrade to a Sturmey 5-speed hub, should you really want to (there’s a small gear range advantage of the 6-speed). If you have an older bike, with either a Sturmey or SRAM hub, the new rear frame will allow you to fit either hub. Useful for globe-trotters expecting calamity in the Gobi Desert. Incidentally, the new Sturmey 3- speed, like the last Nottingham- built hubs, features ‘ball-locking’ positive engagement – in other words, it should be impossible to wind up in neutral, as occasionally happened when the old hubs where out of adjustment.The Sturmey also has a better reputation for keeping out dirt and grime, so it’s very much a positive step.
Gear selector
The old Sturmey 3-speed shifter was much loved, but has been showing its age (it was designed 70 years ago).The SRAM design is less positive and liable to all sorts of minor niggles, so Brompton designed its own to coincide with the reintroduction of the Sturmey hub, and it will be fitted to all 3-speed bikes.The shifter has a long travel, but to keep it nice and ergonomic there are two levers, one above the other.To change down from 3rd to 2nd, you flick down the lower lever.To change from 2nd to 1st, the upper lever will be in exactly the same place.The lever has to be carefully positioned to work well, but when it does, it’s superb – comfortable and easy to use. Like the rear frame, the new shifter will work with either SRAM or Sturmey hubs, so you can upgrade an older bike if you want.
Rims
A perennial grumble from high mileage owners is rim wear. Brompton isn’t promising to eradicate the problem, but the new ZX1000 rims are better quality, more precisely machined and including a wear indicator slot – when the slot disappears it’s time to change. Anodised (but not on the wearing faces) the rims certainly look smarter, but we’ll have to wait a few months to discover whether they really are tougher in service.
These changes don’t sound very exciting, but there might be a tiny clue in the following exchange: ‘Is this the 2005 Brompton?’, we asked. ‘No’, they replied. Make of that what you will.
