Clive Sinclair
What happened to one of Britain's finest inventors after the C5?

Born in Surrey on 30th July, 1940.
In 1961, after becoming chief editor of the magazine "Practical Wireless", he handed in his notice and registered "Sinclair Radionics Ltd" as a company.
In 1972, marketed the world's first pocket calculator, in 1976 marketed the first digital watch and in 1977 marketed the first pocket television.
Demonstrated the ZX80, an affordable personal computer in early 1980, and by the end of the year had sold 20,000. This later became the ZX81.
In April 1982, launched the ZX Spectrum, which changed the face of computer gaming in the home.
Was knighted in 1983.
In 1985, unveiled the Sinclair C5, a three wheeled vehicle for one person which used a small motor powered by rechargeable batteries.
The C5 was not well received by the press or the public and was not nearly as successful as Clive's earlier products.

In the 1990s he has produced an electronic powered bicycle and the worlds smallest AM and FM radios.
After stepping down as chairman of Mensa in 1997 (a position he had held since 1980), membership had grown from 1,700 to 38,000.
The Sinclair C5 has now become a collectors item.
Rumoured to be in talks about crossing the Sinclair C5 with a fibreglass Reliant Robin.
Clive is a keen poker player and has appeared on TV on the shows "Late Night Poker" and "Celebrity Poker Club".
Clive continues to work on new inventions and in 2006 invented the A-bike, a light-weight bicycle which can be folded down small enough to fit inside a ruck sack.

Having to wait ages to load games on cassette on the ZX Spectrum.
The (untrue) rumours that the C5 was powered by a washing machine motor.

In 1983, ZX Spectrums sold at a rate of 12,000 a week.
Despite the failure of the C5, car manufacturers have recently suggested that the small car market has great potential growth.
