A-Bike

So named, because of its ‘A’ like shape in use, the uniquely styled A-bike feels much like a normal bike to ride. However unlike other folding bikes it can easily be slipped into a bag while you hop on the tube, train, bus, or even a plane.

How does it fold?

In under 10 seconds

With a 3 click telescopic mechanism

To a folded size just 67 x 30 x 16cm

Why is it so light?

The Frame Materials
Heat treated aluminum and high strength glass fibre reinforced engineering polymer constitute the majority of the frame.

The Twin Chain
The twin chain gearing system specifically uses small drive axles, often one of the heaviest parts of a traditional bicycle. Pedal cadence remains the same as a normal

The Wheels
Each weighs only 350g and this includes the pneumatic tyres which give such a smooth and comfortable ride.

The Brakes
Designed specifically for the A-bike, the semi circular band brakes fit the wheel perfectly providing a lightweight and robust alternative to traditional shoe brakes.

The wheels are quite small – 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 allows 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 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.

More about the A-Bike

Sir Clive explains “The principle use for the A-bike is city or town travel over relatively short journeys but also very much for mixed-mode journeys where you’re hopping on and off a bus or a train.

For example a typical commuter needs to get from home to local station and then from destination to his or her office – and all without any worries about portability, parking or security.”

“The key to its successful introduction,” adds chief designer, Alex Kalogroulis, “is an entirely fresh approach to the main challenge: how to minimise weight and optimise foldability while retaining full functionality.

At the heart of the solution are light, highly-reliable telescopic tubes coupled with telescoping brake cables."

Sinclair Research Limited was founded by Sir Clive Sinclair in 1979 to design, develop and market major innovations in consumer electronics and, subsequently, personal transport.

Major highlights include: the Sinclair Executive calculator, the world’s first truly pocket calculator; the Sinclair ZX80, ZX81 and ZX Spectrum computers (which pioneered the home-computer wave, the last being the first computer to sell a million units globally), the Flat-Screen Television and Zike, an all-electric bicycle. Each stems from a tradition of innovative design, miniaturisation and ultra-low cost.

Since 2000, Sinclair Research has pursued two principal research directions:

• Continuing development of its electric propulsion technology for an expanding range of applications.

• In personal transport to deliver major innovation in the development of an entirely new generation of ultra light-weight folding bikes.
