A prototype 4-speed TSR was shown at Bradford on Avon on saturday, as part of the annual Moulton Bicycle Club event.
The gearing combines a Schlumpf Speed Drive and Fichtel & Sachs Duomatic. This means that gear-shifting and rear braking is done without cables, allowing the bike to be separated, without the need for cable splitters.
Gear changes for both Speed-drive and Duomatic are activated by the feet. Gear change in the Duomatic is effected by pedalling backwards about 1/4 turn. Changing gears on the speed-drive is done by tapping a button on the pedal crank with the heel.
The Fichtel & Sachs Duomatic contains a coaster brake, activated by back-pedalling.
The 4-speed TSR was visually stunning. The bright white paintjob contrasted beautifully with the new Moulton Bicycle Company headbadge, and a Union Jack on the seat tube. It was very similar to Team GB's Olympic colours.
The new headbadge, which will adorn all Moultons in future, depicts a cyclist on a Moulton (probably a TSR) infront of The Hall. Colours are traditional AM Red, with the new blue, on a shiny silver background. A Union Jack silhouette appears underneath, along with the words "Made in England".
The prototype also sported Moustache-style handlebars, and a reverse-action brake lever to operate the front brake.
The Sachs Duomatic has been out of production for many years, but a large number of "New Old Stock" seems to be available from various sources.
