Sinclair Research is the company run by prolific inventor Sir Clive Sinclair.
Sinclair's first hit product was the ZX Spectrum, released in 1982. The British-made computers were a commercial success, and the company released a wave of new tech products. But Sinclair's luck didn't hold, and it was forced to start cutting prices for its product line. Eventually Sinclair's technology products were sold to British businessman Alan Sugar in 1986.
One of Sir Clive Sinclair's most famous inventions is the Sinclair C5, a bizarre one-man electric vehicle. The public hated it, and hardly anyone bought it.
The number of staff at Sinclair dwindled from 140 in the 1980s to just Sinclair himself in 1990. The inventor wasn't deterred, however, and used his savings to fund the development of new ideas. Since then, Sinclair has released an electric bike, an electric wheelchair, an electric underwater scooter, and a folding bike.
