I could never quite see a place in the transport system for the Sinclair C5. I remember seeing one at the Big Green Gathering, being charged-up at the base of a wind generator, then racing round the site. Since buying my electric bike, and seeing what technology is now available to propel us around, I thought of the C5, and wondered if it would now be accepted. This trike by Twinkle seems to come close to a 'nude' C5! I have never ridden a recumbent, but they seem a good way of applying human effort to the pedals. My brother and others have long had problems getting the 'Feet Forward' concept accepted in motorcycling circles, but they definitely work.
