The Sinclair c5 is a 3-wheeled, battery operated vehicle invented by Sir Clive Sinclair. Development began in the 1970s and progressed slowly until 1983 when British legislation changed to allow sale of such a vehicle. The c5 is a tricycle steered by handles on either side of the driver’s seat that can be pedaled or battery powered. The low top speed allowed it to be driven in Great Britain without a drivers license.
The c5 suffered design problems including: cold weather would shorten the battery life, exposure of the driver to the elements, and safety concerns due to the height. An extra battery, side curtains, and a reflector on a pole addressed these concerns. Impractical for the climate and possibly dangerous on busy roads, sales never took off and the company quickly closed.
