Four wheeled downhill gravity biking is taking the UK by storm, and Bev Rimmer from the group Rough Riderz tells CTC all about this new hi-octane sport.
It's fast, it's furious and completely exhilarating. It's the adrenaline addict's perfect day out. Get strapped in and hold on tight as you hurtle round the corners and down the slopes of some of the UK's finest woodland trails.
Welcome to Rough Riderz, and the crazy world of four wheeled, downhill gravity bikes. These bikes have a custom-built frame, adjustable seat and footplate, off-road tyres, hydraulic brake system, and a safety harness system built into the seat and footplate.
