Most bike covers are a false economy. Thin, flimsy material that rips within weeks and blows away in the first strong wind. We know, because we spent years testing them before designing our own. At 2.5kg, the BTR Heavy Duty Waterproof Bicycle Cover is built from thick 210D Oxford fabric with PVC lining, double-stitched seams and waterproof tape over every join. It sits on your bike solidly, shrugs off rain, snow and UV, and stays put in the worst British weather.
