Although multiple-speed bicycles were widely known by this time, most or all military bicycles used in the Second World War were single-speed. Bicycles were used by paratroopers during the war to help them with transportation, creating the term "bomber bikes" to refer to US planes dropping bikes for troops to use. [61]
The bikes are also used to start a Keirin race for speed skating (replacing the Derny in a velodrome). In a keirin for skaters, the bike starts on the opposite side of the oval and the skaters then start from a standing start as the bike passes them. The bike then regulates the speed, which increases over two laps, before slowing and moving to ...

Racing skates, also known as speed skates, have long blades and are used for speed skating. A clap skate (or clapper skate) is a type of skate where the shoe is connected to the blade using a hinge.

The first to surpass 200 km/h was the Frenchman Jose Meiffret in 1962, when he reached 204 km/h (127 mph) behind a Mercedes-Benz 300SL car on a German motorway. [30] Allan Abbott, a cycling enthusiast and motorcycle racer, elevated the motor-paced bicycle speed record at the Bonneville Salt Flats, reaching 223 km/h (139 mph) in 1973.
The Michaux company was the first to mass-produce the velocipede, from 1857 to 1871. That French design was sometimes called the boneshaker, since it was also made entirely of wood, then later with metal tires. That in combination with the cobblestone roads of the day made for an extremely uncomfortable ride. These velocipedes also became a fad ...

The dandy horse, an English nickname for what was first called a Laufmaschine ("running machine" in German), then a vélocipède or draisienne (in French and then English), and then a pedestrian curricle or hobby-horse, [1] or swiftwalker, [2] is a human-powered ...
The base value of a single Axel is 1.10, a double Axel 3.30, a triple Axel 8.00, a quadruple Axel 12.50 and a quintuple Axel is 14. [8] Paulsen was the first skater to accomplish an Axel, at the first international figure skating competition, which was held in Vienna in 1882, while wearing speed skates.
