It was developed by the British inventor and entrepreneur Sir Clive Sinclair (also known for his home computer kits ZX 81 and ZX Spectrum) and was the first mass-produced electric bicycle.
But due to a bad marketing and very negative and squibbing press reports it was a total flop when it was introduced on the market in January 1985.
And so the production was quit in the same year after just approximately 17.000 units build.
Despite this launch failure the C5 enjoys great popularity within a small group of fans and attained cult status.
A real freak vehicle!
