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. ==Events== *1868 – The first steam driven two wheeled vehicle is the Michaux-Perreaux steam velocipede created in France.〔http://www.khulsey.com/motorcycles/early-steam-gas-motorcycle-history.html| Early Steam Cycle History〕 *1869 – Sylvester H. Roper of Massachusetts, USA creates a steam velocipede which he shows at fairs and circuses.〔http://americanhistory.si.edu/onthemove/collection/object_271.html| America on the Move, Smithsonian Institution, Roper Steam Velocipede〕 *1885 – Gottlieb Daimler and Wilhelm Maybach of Cannstatt, Germany put their newly developed "grandfather clock" engine in a two-wheeled frame to demonstrate their automobile engine. The Daimler ''Reitwagen'' is the first internal combustion motorcycle.〔http://www.falconmotorcycles.com/blog/falcon-blog/1-motorcycles/194-the-pioneer-gottlieb-daimler.html|Daimler Petroleum Reitwagen〕〔(Deutsches Zweirad Museum- Neckarsulm ), First Motorcycle.〕〔(Celebrates 125 Years of the Automobile ), By Pia Reutter.〕 *1896 – Roy C. Marks of San Francisco produces the first motorcycle made in the USA. It becomes the California Motorcycle.〔(California and Yale History ), Roy C.

It is a purpose built motorcycle.〔(Laurin & Klement ), Laurin and Klement the first Motorcycle layout.〕 *1900 – Due to poor handling Werner move the engine to the bottom of the frame and patent the design. The 1900 Werner is the first motorcycle layout. *1900 – The Singer Motor Wheel was a wheel attached to a small internal combustion engine that would be substituted for the front wheel of a bicycle, motorizing it *1903 – A California motorized bicycle ridden by George Wyman became the first motor vehicle to cross the North American continent.〔Rafferty, Tod, ''The Complete Illustrated Encyclopedia of American Motorcycles'', Philadelphia, PA: Courage Books (1999), p. 22〕 *1903 – 1962 The "Shaw Manufacturing Co." () of Galesburg, Kansas advertises an 241cc chain-drive engine kit (1903 – 1915) for motorizing a bicycle in "Popular Mechanics" magazine for $90. *1914 – The Smith Motor Wheel was introduced, similar in concept to the Singer, but was designed to be fixed to the rear of the bicycle, rather than to replace the front wheel. The design was later picked up by Briggs & Stratton. () *1918 – Evans Power Cycle *1919 – Johnson Motor Wheel *1939 – The bolt-on Whizzer bike motor is introduced; production continues until 1962 (). In Australia, the ''Autocycle Malvern Star'' was introduced, following the pattern of the British ''Autocycle'' () *1946 – In Italy, Vincenti Piatti had designed a 50cc engine unit for driving portable lathes and also foresaw the possibilities of this engine power-assisting a bicycle – the ''Mini Motore''. () *1946 – The initial iteration of the VéloSoleX motorized bicycle is introduced to the French Public. () *1948 – The Trojan Minimotor begins production in Britain and becomes immediately popular. () *1949 – The ''Mobylette'' is introduced in France. Its concept was ''"a bicycle with a nice permanent back wind"''. 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 students develops the Twike sociable tandem delta tricycle. The prototype was a purely human-powered vehicle but all 850 production vehicles were motorized. Most of these retained an effective pedal drive. *2003 – Rif Addams re-enacts George Wyman's 1903 San Francisco to New York run, on a custom-built Whizzer. *2006 – Motorized Bicycling enjoys a resurgence in popularity, both as hobby and serious alternative transportation. *2006 – Motorized Bicycle racing began in Tucson,Arizona with Death Race *2008 – The first "National" rally in the USA, specifically for Motor-Assisted-Bicycles, took place in Ocean Park WA. 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. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Timeline of motorized bicycle history」の詳細全文を読む スポンサード リンク
