Britain's Environmental Transport Association (ETA) have taken advantage of the early winter snow to demonstrate their caterpillar track-driven snow bike.
The kit is manufactured by Canadian company K-Trak and converts any existing 26in hardtail or full-suspension mountain bike into a snow bike. A single ski replaces the front wheel, while a specially designed rear wheel and rubber track setup enables the rider to retain use of their gears and rear brake.
The ETA used the K-Trak system to build its 'Bond bike' concept bike for the recent Cycle Show 2010 in London, primarily to promote the ETA's cycle insurance policies. However, the organisation's Yannick Read seized the opportunity provided by the recent snow in Britain to carry out a real-world test of the system.
