The A-bike is a folding bicycle released by Sir Clive Sinclair in the United Kingdom on 12 July 2006. It was designed by Hong Kong design agency Daka, in collaboration with Sinclair Research, over a 5-year period. It was announced to the public in 2004. Clive Sinclair envisioned the A-bike, and Alex Kalogroulis was the main designer. It weighs and folds to, small enough to fit in a rucksack. The first version had wheels, which was increased to in later models. In 2015, an electric version, the A-Bike Electric, was introduced to the public as part of a Kickstarter campaign.

History
The A-bike was designed by Sinclair Research, in collaboration with Hong Kong design agency Daka, over a 5-year period. It was announced to the public in 2004. Clive Sinclair envisioned the A-bike, and Alex Kalogroulis was the main design engineer. It was released on 12 July 2006, and was priced at £199. The official Europe distributor, Mayhem UK, hoped to sell 25,000 units in the first 12 months. By 2007 it was being noted that a "large number of counterfeit" A-bikes were appearing in China and elsewhere. Early reviews praised the A-bike for being lightweight and easy to fold, but noted the flexing frame and uncomfortable saddle, and criticised the tiny wheels for being unsafe on uneven roads. In 2008 the Mark-II version was released: officially known as the A-Bike Plus. This version had strengthened aluminium tubing, a new air-sprung cushioned saddle, and an upgraded drive mechanism. The Mark-III version was released in 2010, and was officially known as the A-Bike City. The main changes were larger wheels and it was priced at £299.99.
Characteristics
The A-bike is a small wheel bicycle with wheels, increasing to in later models. The original model weighs, and folds to reducing its volume to about 25% of its original size. A twin-chain system enables the bike to travel about per crank rotation despite the bicycle's small-diameter wheels. The crankcase housing almost completely encloses the drive mechanism, protecting it and preventing oil stains on clothing or floor surfaces. The bicycle is more stable than it may seem by design, but it would be more stable if it had needle bearings on the steering axle, this is the true source of its perception of unmanageability but also the fact of mounting inverse the steering fork, due to manufacturing error, something not commonly perceived if the case.
In 2015, an electric version, the A-Bike Electric, was introduced to the public as part of a Kickstarter campaign. The design featured 8-inch wheels, as well as a larger seat and sturdier frame. The funding campaign was successful and production began before the end of the year.
