“So named because of its "A" like shape in use, the A-bike is designed to be folded and unfolded* in under 10 seconds with a 3 click telescopic mechanism, to a folded size just 67 x 30 x 16 cm. Heat treated aluminum and high strength glass fibre reinforced engineering polymer constitute the majority of the frame. Weight: 5.6kg. The internal twin chain gearing system is totally encased at the rear. Pedal cadence remains the same as a normal bike.”. The A-bike, from Sinclair Research.
