Sinclair C5 Prototypes

During the development of the C5 there were allegedly about 5 or 6 prototypes running continuously in 12 hour shifts on a test track. Two of these prototypes feature in the Sinclair C5 Preview video which was recorded in 1984 just before the release of the C5 in January 1985.

Here we have lots of pictures of various C5 prototype items. Special thanks to Chas for supplying the images.

Ride a Sinclair C5 and jump as high as possible. Do mid-air spins for more points.
