The A-bike is a type of folding bicycle invented by Sir Clive Sinclair
in the United Kingdom and released on 12 July 2006. It weighs 5.5 kilograms and
folds to 67×30×16 cm, small enough to fit in a rucksack.
Clive Sinclair envisioned the A-bike, and Alex Kalogroulis was the main design engineer.
Is the A-bike easy to ride?
YES. The use of a dynamically geared twin chain system enables users to pedal normally and retain their balance. The high performance 90psi pneumatic tyres allow for a smooth and comfortable ride on most hard surfaces. The size of the wheels is of course a key factor in making the bike so lightweight and compact.
Does the A-bike have a chain and gears?
YES. In fact the A-bike has 2 chains! 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.
Is the A-bike easy to fold and unfold?
YES. The 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.
Is there a height or weight limit for using the A-bike?
YES. We recommend a minimum height of 4' 9` but the saddle height is easily adjustable to accomodate up to 6'3` We 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.
