The Sinclair c5 is a 3-wheeled, battery operated vehicle invented by Sir Clive Sinclair. The C5 is a recumbent tricycle steered by handles on either side of the driver’s seat, and it may be either pedaled or battery powered. 

This little 6 ½’ long ski-tug was produced in Hamburg, Germany for the leisure market in Europe and the US, and was quite popular before the popularity of more mainstream personal watercraft. This 24hp engine was the first large-scale production of a rotary. 

This Skoda Octavia is totally original except for the fluids, battery, and tires.  It has a mere 2,384 miles on it.

Also called the suitcase bike, the Skoot was intended for the commuting working professional to conceal and easily transport his or her ride while also avoiding the separate bicycle tickets necessary on many UK public transport systems. 

This small 2-seater car was designed to be used in heavily-populated urban areas.  Smart decided in 2000 to expand its line of cars, and showed a concept of the smart Roadster at the 2000 Paris Motor Show.  Smart Roadster production finally started in 2003, and initial sales were very strong.

Smart–designed by the watch maker Swatch and built by Mercedes–is ideal for maneuvering (either driving or parking) in large cities. Smart comes in many models. 

In 1952, disabled Russian veterans of World War II (or the “Great Patriotic War” as it was called in the USSR) received their long-overdue motorized transportation in the form of a government provided open three-wheeler, the SL1. Built by a motorbike company in Serpukhov, the light vehicle proved that having only 3 wheels was an impractical choice for the Russian snow, sleet, and mud.
