"The idea is that if you have a bicycle which is seriously lighter and more compact than anything existing at the moment, it will change the way in which people see bikes."
Sir Clive Sinclair, inventor of the A-bike

The A-bike City's 8" diameter wheels are carefully drilled to provide optimum weight and strength.

The high performance 90psi pneumatic tyres allow for a smooth ride on most hard surfaces.

In addition the use of a dynamically geared twin chain system enables users to pedal normally and retain their balance.

A-bike is designed to be folded and unfolded in under 10 seconds.

It takes only a few minutes to learn how to do this with a simple step by step guide provided with the A-bike.

Sinclair recommend a minimum height of 4' 9` but the saddle height is easily adjustable to accomodate up to 6'3` and have set the maximum user weight to 85kgs/13st 5lbs to ensure optimum performance and routine safety, although the A-bike is fully tested to above this weight.

The internal twin chain system is totally encased at the rear of the A-bike which has the benefit of keeping grease and dirt away from clothes and hands. The A-bike has a single gear transmission optimised for short journeys and easy use.
