Introduce a bike, The X-bike. This was to have small wheels 每 essential elements when trying to save weight and space on a folding bike.
> The frame 每 two main frame elements fold in a scissor action by a skew joint. This allows the wheels to fold side by side.
> Steering 每 this was by auto-tensioned cables via variable ratio pulleys. These provide a good steering feel to hub-centre steering.
> Drive 每 this was by internal belt or miniature chain.
> Construction 每 this uses injection-moulded long fibre carbon and glass shells ultra-sonically welded together. Fusible core, foam and gas injection technologies were also used.
> Tyres 每 solid tyres were developed as an option with PU versions performing better than pneumatic equivalents.
This project was undertaken in collaboration with David Southward (CCL founder) and Shaun Househam. More Pics. |
