A-bike

The A-bike is a folding bicycle released by Sir Clive Sinclair in the United Kingdom on 12 July 2006.

[4] Early reviews praised the A-bike for being lightweight and easy to fold, but noted the flexing frame and uncomfortable saddle, and criticised the tiny wheels for being unsafe on uneven roads.

A twin-chain system enables the bike to travel about 3.2 metres (10.5 ft) per crank rotation despite the bicycle's small-diameter wheels (6 inches or 15 centimetres).

The crankcase housing almost completely encloses the drive mechanism, protecting it and preventing oil stains on clothing or floor surfaces.

Richard Hammond and James May carried A-bikes in their suitcases and unfolded them to bike from a ferry dock to a cable car.
