The Sturmey Archer 2 speed, coaster brake hub, as fitted to the Moulton TSR 2, is reviewed in the current issue of Velovision (Issue 40).

The reviewer tested the old F&S Duomatic hub alongside the new Sturmey S2C for a better comparison between the two hubs. Some of the main findings were:

• The S2C is about 50% heavier than the Duomatic
• gear ratios are identical
• the S2C requires less of a back-pedaling action in order to change gears
• the brake on the S2C is much stronger

The review is very positive, and the main benefits cited are that you get the simplicity of a fixed gear with a “bailout” gear for hills and headwinds, as well as the lack of cables going to the rear, which is particularly useful for separable Moultons.

Issue 40 also includes an article by Moultoneers Keith Hales, where he describes life with a Double Pylon, and includes his visit to the 2009 Moulton Summit in Japan.

The initial prototypes, which were shown last year, featured a belt drive, eliminating the maintenance and dirt associated with chain drives.

However, the production TSR 2 is available with a choice of either belt drive or a standard chain drive. The belt drive model features a Delta 11mm belt, 67 tooth chainring and 25 tooth sprocket, providing approximately 50.6 and 69.9 inches.

The chain drive features a 44 tooth chainring and 17 tooth sprocket, giving gears of approximately 48.9 inches and 67.5 inches.

The TSR 2 weights 12kgs, and also features folding pedals and Avid Single Digit 5 front V-brakes.

Beautiful simplicity – the TSR 2 features the new Sturmey-Archer ‘kick-shift’ two-speed gear with an integrated back-pedal brake, and belt-drive. Two well-spaced ratios keep you moving through city streets – no shifters, no cable, no adjustment.

I woke early and walked into Bradford on Avon to purchase some items for breakfast. When I returned the place was buzzing with activity. The Bring and Buy sale was packed with club members hoping to find spare parts, wheels, racks, tyres, books and even whole bicycles. I needed to travel light, so I resisted temptation and only bought some spare tyres at the Moulton Bicycle Company table.

Outside, members mingled and chatted about their purchases, discussed bikes, modifications and accessories. The Moulton Bicycle Company opened up the shop, and put many models on display. Club members were treated to the TSR2, the new Moulton Speed, the AM20-2 with lighter, more compact frame, as well as many more established models.

In the afternoon, the crowd gathered round for the expert discussion in glorious sunshine. Alex Moulton arrived on his New Series Pylon, and to everyone’s delight, he circled the courtyard several time on his Pylon, before taking his seat. Tony Hadland welcomed everyone, and introduced the first guest, Jim Glover, who famously set a speed record of over 51mph on a Moulton in 1986, which has never been broken.

Jim entertainingly told the story of how he got involved with the record breaking attempts and some of the problems and incidents along the way. One such problem during testing was with steering stability at high speed – Moultons are designed to be maneuverable – which was temporarily solved by attaching a bungee cord to the front forks to act as a steering damper. Alex interrupted to inisist that this was not a proper solution, and that reversing the forks to create a large trail was the correct solution.

Several members brought along examples of the S range of Moulton bicycles from the 1960s. The S range was built by Jack Lauterwasser in a separate premises in Bradford on Avon. The S range was built to a higher specification than the normal range, and were built to order, so many variations occur. The experts estimated that “hundreds rather than thousands” were made, and probably as few as “low hundreds”.

An S Deluxe, several S safaris and an S Stowaway were shown by members, and tales of their acquisitions were told. Only one was bought for a high price on ebay, and several were bought in poor condition including one that had it’s original chrome covered with black paint, which probably served to protect the chrome for years before Nitromors helped reveal it’s original glory.

The subject of friction dampers – which were fitted to the S range – came up, and Alex said they were not necessarily a good idea… “but we fitted them anyway”. He said that there was built in damping in the hysteresis of the rear suspension rubber, and with the friction of the front suspension. Suspension engineers were concerned with additional damping only to deal with the problem of riders moving about excessively, instead of “doing what they are supposed to be doing, which is sitting down and pedalling”.

Several members also displayed examples of the Land Rover APB, which was launched 15 years previously.

Alex was asked whether “docking the tail” of an F-frame adversely affected the structure of the bicycle – a topic of frequent debate among Moultoneers. He started by telling how he was annoyed with John Woodburn, when John removed the rack and cut off the tail of the London-Brighton record breaking Moulton, in order to save weight. Alex had wanted the record to be broken on a standard specification bicycle. He finished by discouraging owners from modifying their frames… “my advice is don’t do it!”.

Later in the evening, while other members enjoyed silver service at the club dinner, I decided to stay in the sunshine, and enjoyed a relaxing barbecue on the lawn.

On Sunday morning, Dan Farrell led our group of 19 on one of the three organised rides. The route was spectacular, taking in country lanes with sweeping views, charming villages, a couple of tough hills and a nice stop for tea and cake along the way in Lacock.

We arrived back at the Riverside Inn in Bradford on Avon in time for a lunchtime pint, and I got chatting to Jim Glover. Jim regaled us with anecdotes about the record breaking rides, and about his current role as a cycling coach in Ottawa, Canada. All too soon, it was time to walk back to the Hall, pack up the camping gear, say lots of goodbyes and head for the train station to start the long journey home.

Every Moulton weekend at Bradford on Avon is special, but I think I enjoyed this one most of all.

In September 2010 I will be riding 300 miles from London to Paris to raise money for the Alzheimer’s Society. But things are never that straight forward – I will be riding my distinctive Moulton bicycle, immediately recognizable by its little wheels.Genius or lunacy? Stick around and find out. Follow my vlogs as I train and participate in this event.Donations large or small to the Alzheimers Society are all gratefully received, just use the address at the end of the video.Thank you for your support.

He has produced some cool videos showing the Moulton in all it’s glory, including “It’s not about the bike” shown below.

There were three of us in the group – one large wheeler, one Moulton TSR and my own Moulton APB.

We wild camped 4 nights, used a campsite 1 night, and stayed in a “Hutte” 1 night.

Moulton have never built a factory tandem, but several Mouton based tandems have been created as custom projects, by third-party framebuilders.

Several APB based tandems have been built by Doug Pinkerton. Here is one example of a Doug Pinkerton Moulton APB Tandem

To further reduce maintenance and adjustment requirements, the TSR-2 is equipped with a belt-drive transmission. Unlike chains, the belt is clean and does not scratch, so no adjustment is required to take up slack. Efficiency is as high as a chain in good condition, and a belt is always in good condition! With no gear cable, rear brake cable, or chain to adjust, there is little that the everyday cyclist has to do to keep his TSR-2 running sweetly.

The TSR-2 will be available from Spring 2010.

Over September 12th-13th, Moultoneers from across Britain, Europe and the world gathered in Bradford on Avon for the annual Moulton Bicycle Club weekend. In the picturesque surroundings of The Hall, the Moultoneers enjoyed bright September sunshine and a procession of bicycles old and new including some lovingly-restored examples of Moulton history which were discussed by a panel headed by Dr. Alex Moulton.

Moulton Tour SR

Amongst the many interesting bicycles, Moultoneers were able to view the new TOUR SR and Special Edition TSR-9 Moultons, on display for the first time. The TOUR SR shares a similar specification to the TSR-30, with additional comfort provided by the Brooks Swift titanium leather saddle, Brooks leather handlebar tape and mudguards fitted as standard. There’s also a light tubular stainless steel water bottle cage.

The Special Edition TSR-9 is based on a model produced this year for Moulton’s Japanese distributor, Dynavector Systems. It features chrome plated front and rear forks, Brooks leather saddle and handlebar grips, and a quill-type handlebar stem from Nitto.

Sturmey Archer had their own stand but the most interesting new hub they’ve produced wasn’t on it – it was nestling quietly on the Moulton stand, who were displaying the only working prototype. The S2C is a re-imagining of the Fichtel & Sachs Torpedo Duomatic hub that Moulton have been busy reviving since they found a bunch of old stock and used them to make a 50th anniversay four speed machine with the Duomatic at one end and a Schlumpf speed drive at the other: four gears and no shifters; no cables either meant that the bike separated easily into two.

The hub is a kickshift with two speeds, simply kick back to switch between ratios. Lean further back on the pedals and you’ll engage the coaster brake. It’s an elegant solution that requires no cabling to the rear of the bike, so it’ll fit in very well with the fixed aesthetic, and it gives you an extra ratio for accelerating and climbing the hills. Sturmey Archer are confident that they’ll shift a ton of the S2C hubs and we’d tend to agree, it’s going to be less than £100 and it’s almost the perfect hub for those stripped back urban machines. Especially if you live somewhere hilly, like we do. Fitchel and Sachs are now SRAM, and they’ve definitely missed a trend here by not digging out the blueprints and reviving the duomatic themselves.
