Invented by Sir Clive Sinclair, A-bike is the result of a five year research and development project by his team at Sinclair Research. Sir Clive said, "...the idea is if you had a bicycle which was seriously lighter and more compact than anything existing at the moment, it would change the way in which people saw bikes."
So named, because of its ‘A’ like shape in use, this original styled A-bike feels very much like a normal bike to ride. However unlike other folding bikes it can be slipped easily into a bag while you hop on the tube, train, bus, or even a plane.
The frame is made from nylon reinforced with glass fibre — similar to that used in the aerospace industry. Interestingly, although the wheels look very small, the pedal power required isn't all that much different from a regular bike, and because the chain system is fully enclosed, you don't have to worry about getting your catching your clothes on the mechanism. It is completely oil-free so it won't make you dirty either.
