With a Sturmey Archer 8-speed hub in the back and a Mountain Drive in the front, it’s got an enormous gear range…

I went to Cycle 2008 yesterday – the BHPC got a free stand because another exhibitor pulled out. There was a beautiful Velokraft carbon lowracer on their stand…

Okay, I think I can make this public now – for a few months, I’ve been working with Nick from CarryFreedom (the trailer people) on Nick’s design of what a tough, simple bike should look like, and this is the result.

The idea is to make something that’s tough (very rigid steel frame), reliable (enclosed chain drive and cables), cheap to manufacture (minimum number of tubes, as little welding as possible), and customisable (side panels that can be decorated, painted, made out of different materials, or wallpapered).

Nick’s taking it to Eurobike at the moment, and it’ll probably be at Cycle in London next month…

…showing how it folds up. Basically exactly the same way as a standard Brompton, but with a smaller chainring to keep the chain even more tucked away inside.

A recent project – the battery hangs behind the seat, and there’s a twist throttle on the handlebar…

A project that was collected yesterday – an Invacare Top-End handcycle fitted with a Heinzmann motor system, and a front disc brake…

Today’s project – took a while to get the front wheel and disc brake working 😉

A new version, using the Heinzmann Li-Ion battery and digital controller.

A Pashley Tri-1 Folding, fitted with a Heinzmann Lithium electric motor kit…

Latest project – a Koga-Miyata Founder S equipped with a DualDrive to
get 27 gears…
