Motor-paced Racing
Motor-paced racing and motor-paced cycling refer to cycling behind a pacer in a car or more usually on a motorcycle. The cyclist (or stayer in this case) follows as close as they can to benefit from the slipstream of their pacer. The first paced races were behind other cyclists, sometimes as many as five riders on the same tandem. Bordeaux-Paris and record attempts have been ridden behind cars. More usually races or training are behind motorcycles. Origins of pacing Cyclists started to use tandem bicycles as pacers in the late 19th century. There could be as many as five riders on the pacing machine.The Bicycle, UK, 21 October 1953, p15 Because of the long distances covered when following a pacer, these cyclists were called stayers, a term used in long-distance horse racing. Companies such as Dunlop sponsored pacing teams,The Bicycle, UK, 6 February 1952, p2 and "tens of thousands" turned out to watch. A south London rider, J. W.

Derny
A Derny is a motorized bicycle for motor-paced cycling events such as during six-day and Keirin racing and motor-paced road races. Some riders train behind a derny on the road. The Derny is so-called as it was originally produced by the French Derny firm, but the name ''Derny'' is now applied to all small cycle-pacing vehicles, regardless of manufacturer. The original Derny The first Derny 'Entraineur' or 'Bordeaux–Paris' moped, with its petrol tank mounted ahead of the handlebars, was built by ''Roger Derny et Fils'' of the Avenue de St Mandé, Paris, France, in 1938. A fleet of Dernys was maintained for the long-established 'Bordeaux-Paris' road-race and the Derny was used for many other track and road events and for endurance training. Derny also built a touring adaptation called the 'Solo' and tandems and mopeds. Being a moped, the Derny had both a Zurcher two-stroke engine and pedals on a chainring sprocket, typically with 70 teeth on the front and 11 on the rear-w ...

Autobahn
The (; German plural ) is the federal controlled-access highway system in Germany. The official German term is (abbreviated ''BAB''), which translates as 'federal motorway'. The literal meaning of the word is 'Federal Auto(mobile) Track'. German are widely known for having no federally mandated general speed limit for some classes of vehicles. However, limits are posted and enforced in areas that are urbanised, substandard, accident-prone, or under construction. On speed-unrestricted stretches, an advisory speed limit () of applies. While driving faster is not illegal as such in the absence of a speed limit, it can cause an increased liability in the case of a collision (which mandatory auto insurance has to cover); courts have ruled that an "ideal driver" who is exempt from absolute liability for "inevitable" tort under the law would not exceed . A 2017 report by the Federal Road Research Institute reported that in 2015, 70.4% of the Autobahn network had only the adv ...

The Mercedes-Benz 300 SL (chassis code W 198) is a two-seat sports car which was produced by Mercedes-Benz as a gullwinged coupe (1954–1957) and roadster (1957–1963).Werner Oswald: ''Mercedes-Benz Personenwagen 1945–1985''. Motorbuch Verlag, Stuttgart 2007, , S. 46 u. 70. It was based on the company's 1952 racer, the W194, with mechanical direct fuel injection which boosted power almost 50 percent in its three-liter overhead camshaft straight-six engine. Capable of reaching a top speed of up to , it was a sports car racing champion and the fastest production car of its time. Max Hoffman, Mercedes-Benz's United States importer at the time, inspired the 300 SL and saw an American market for such a car. The company introduced the 300 SL in February 1954 at the International Motor Sports Show in New York City (instead of Europe) to get it into US buyers' hands sooner.

Grenzlandring
The Grenzlandring (German for "border-region ring"), sometimes written ''Grenzland-Ring'', is a former high-speed oval race track in the Lower Rhine area of Germany, around the town of Wegberg, located close to Mönchengladbach and the Dutch town of Roermond. The Grenzlandring, to many foreigners also known as ''Wegbergring'' or ''Wegberg-Ring'', is told to be "discovered" nearly undamaged after World War II when during one dark night in 1947, Dr. Carl Marcus, town mayor of nearby Rheydt, drove along a more or less straight looking country road. When he passed a bicycle rider more than once, he suddenly realized that this road must be a full circle. In fact, a long and wide egg-shaped concrete ring road had been built before World War II around Wegberg and the neighboring village of Beeck and completed in 1938 or 1939, at total cost of about 3.3 million ''Reichsmark''. As it was intended for military purposes, the construction had not made been public nor was the road shown o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Keirin
– literally "racing cycle" – is a form of motor-paced cycle racing in which track cyclists sprint for victory following a speed-controlled start behind a motorized or non-motorized pacer. It was developed in Japan around 1948 for gambling purposes and became an official event at the 2000 Olympics in Sydney, Australia. Riders use brakeless fixed-gear bicycles. Races are typically long: 6 laps on a track, 4 laps on a track, or 4 laps on a track. Lots are drawn to determine starting positions for the sprint riders behind the pacer, which is usually a motorcycle, but can be a derny, electric bicycle or tandem bicycle. Riders must remain behind the pacer for 3 laps on a track. The pacer starts at , gradually increasing to by its final circuit. The pacer leaves the track before the end of the race (3 laps on a track). The winner's finishing speed can exceed . Competition keirin races are conducted over several rounds with one final.

Velodrome
A velodrome is an arena for track cycling. Modern velodromes feature steeply banked oval tracks, consisting of two 180-degree circular bends connected by two straights. The straights transition to the circular turn through a moderate easement curve. History The first velodromes were constructed during the late 1870s, the oldest of which is Preston Park Velodrome, Brighton, United Kingdom, built in 1877 by the British Army. Some were purpose-built just for cycling, and others were built as part of facilities for other sports; many were built around athletics tracks or other grounds and any banking was shallow. Reflecting the then-lack of international standards, sizes varied and not all were built as ovals: for example, Preston Park is long and features four straights linked by banked curves, while the Portsmouth velodrome, in Portsmouth, has a single straight linked by one long curve. Early surfaces included cinders or shale, though concrete, asphalt and tarmac later becam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
