[Bicycle Bob]

The Sinclair may be the most outrageous example of a design being ruined on the way through production. Detroit Iron in the 50's often turned out like a bas relief of the original model after the tool and die men saw the drawings, but this thing lost half its top speed. The prototype was quite lively and fun, having been developed by Lotus Engineering. It may have been rather dangerous, though, as tall deltas always are, being unable to brake and turn much at the same time. I don't believe I've ever seen one on video, but I did get a short ride, and saw the Giles cartoons about it.
