Timeline of motorized bicycle history
This timeline of motorized bicycle history is a summary of the major events in the development and use of motorized bicycles and tricycles, which are defined as pedal cycles with motor assistance but which can be powered by pedals alone. 19th century
1867–1869 – The first steam driven two wheeled vehicle is the Michaux-Perreaux steam velocipede created in France. 1869 – Sylvester H.

This pattern gave its name to the French slang term for moped. 30 million copies were produced until 2002, evolving much through different models during half a century. 1950 – The British-made Cyclaid 31cc bolt on bicycle motor is introduced. This same year also sees the introduction of the popular Cyclemaster motor wheel, also made in Britain from a design by the German DKW company. 1952 – The 18cc German Lohmann is one of the few semi-diesel bike motors ever produced and is claimed to be the world's smallest bike motor. 1966 – The Vélosolex 3800 is introduced and becomes the most popular version of the Vélosolex motorized bicycle, production continues until 1988. 1968 – The Honda P50 the last vehicle to incorporate a motor wheel as a power unit is discontinued. 1975 – Sears begins selling the Tanaka Bike Bug motor under its own Free Spirit brand name; U.S. sales of the Bike Bug continue until 1985. 1982 – The "Bumble Bike" friction drive (now Golden Eagle belt drive) is chosen as "Official Transportation" at the Knoxville Worlds Fair. 1985 – The Tour de Sol leads to the development of modern electric bicycles in Switzerland. 1986 – A group of Swiss students develops the Twike sociable tricycle. The prototype was purely human-powered, but all 850 production vehicles were human-electric hybrids. 2000 – Honda Step Compo, first folding electric bicycle. 21st century

There were 29 bikes, of various styles, representing 4 states. 2008 – A motorized bicycle ridden by Augie Deabler is accepted as an official entrant at the Bonneville Salt Flats "World of Speed '08." He used a Golden Eagle/Tanaka 32cc, and recorded a top speed in the standing mile of 32.4MPH. 2011 – Motorized Bicycle racing began in Southern California at the Willow Springs International Motorsports Park Go Kart track in Rosamond, CA on June 18, 2011. SoCal Motor Bicycle Racing continues to hold races in Southern California at Grange Motor Circuit in Apple Valley, California after the first race on October 20, 2011, and at Willow Springs International Motorsports Park. 2020 – Ufeel supercapacitor electric bicycle without battery introduced.
