First Known Use: 1894


noun    (Concise Encyclopedia)

Bicycle or tricycle propelled by an internal combustion engine. The first motor tricycle was built in 1884 in England, and the first gasoline-engine motorcycle was built by Gottlieb Daimler in 1885. Motorcycles were widely used after 1910, especially by the armed forces in World War I. After 1950 a larger, heavier motorcycle was used mainly for touring and sport competitions. The moped, a light, low-speed motor bicycle that can also be pedaled, was developed mainly in Europe, and the sturdier Italian-made motor scooter also became popular for its economy.
