Origin of Motor-Scooters

The first practical engines and motorcycles were designed by the French and Belgians, followed by British, German, Italian, and American makers.

The popularity of the vehicle grew, especially after 1910. During World War I the motorcycle was used by all branches of the armed forces in Europe, principally for dispatching. After the war it enjoyed a sport vogue until the Great Depression began in 1929. After World War II a revival of interest in motorcycles lasted into the late 20th century, with the vehicle being used for high-speed touring and sport competitions.
The practice of attaching auxiliary engines to bicycles in western Europe and parts of the United States led to the development during the 1950s of a new type of light motorcycle, the moped. Originating in Germany as a 50-cubic-centimetre machine with simple controls and low initial cost, it was largely free of licensing and insurance regulations except in Great Britain.

The more sophisticated motor scooter originated in Italy soon after World War II, led by manufacture of a 125-cubic-centimetre model. Despite strong competition from West Germany, France, Austria, and Britain, the Italian scooters maintained the lead in the diminishing market. The scooter has small wheels from 20 to 36 cm (8 to 14 inches) in diameter, and the rider sits inside the frame. Power units are placed low and close to the rear wheel, which is driven by bevel gearing or chain. Capacities vary from 50 to 225 cubic cm, and four-speed gearing is common.
