Cycle Speedway
Cycle speedway is a form of bicycle racing on short oval dirt tracks, usually outdoors, occasionally indoors, typically 70–90 metres long. Like motorcycle speedway, riders use machines without brakes or multiple gears but, unlike motor speedway, the object is not to slide bikes round the turns. Origins The origins of cycle speedway are obscure. It existed by the 1920s but appears to have taken off in the wreckage of post-war cities in Britain. With tracks cleared through the rubble, on bikes not otherwise roadworthy, and under the influence of motorcycle speedway, cycle speedway grew haphazardly as a way for young people to enjoy themselves in cities. London, with most bomb sites, led in organising races, in 1945. There were more than 200 clubs in East London by 1950, with more than 20 in Walthamstow alone. The sport spread across the country. The Birmingham league had 22 teams in its first season. Coventry, Leicester, Wolverhampton and Cradley Heath followed. Intercity ...

Bicycle Racing
Cycle sport is competitive physical activity using bicycles. There are several categories of bicycle racing including road bicycle racing, cyclo-cross, mountain bike racing, track cycling, BMX, and cycle speedway. Non-racing cycling sports include artistic cycling, cycle polo, freestyle BMX and mountain bike trials. The (UCI) is the world governing body for cycling and international competitive cycling events. The International Human Powered Vehicle Association is the governing body for human-powered vehicles that imposes far fewer restrictions on their design than does the UCI. ThUltraMarathon Cycling Associationis the governing body for many ultra-distance cycling races. Bicycle racing is recognised as an Olympic sport. Bicycle races are popular all over the world, especially in Europe. The countries most devoted to bicycle racing include Belgium, Denmark, France, Germany, Italy, the Netherlands, Spain and Switzerland. Other countries with international standing inc ...

ETRTO
The European Tyre and Rim Technical Organisation (ETRTO) exists to specify and harmonise sizes of rims and their associated pneumatic tyres across the European Union. ETRTO sizes apply to rims and tyres for vehicles of all types, including bicycles. The great advantage of ETRTO sizing is that it is unambiguous; previously, nominal dimensions were used which were interpreted in different ways by different countries and manufacturers - a problem for the end user. ETRTO works in liaison with the International Organization for Standardization to develop relevant standards.

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. Some eliminated cyclists can try ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyclo-cross Bicycle
A cyclo-cross bike or cyclo-cross bicycle (abbreviated CX Bike or CXB) is a bicycle specifically designed for the rigors of a cyclo-cross race. Cyclo-cross bicycles roughly resemble the racing bicycles used in road racing. The major differences between the two are the frame geometry, and the wider clearances that cyclo-cross bikes have for their larger tires and mud and other debris that they accumulate. Cyclists have been competing in races on road-going bicycles since the 19th century. Cyclo-cross emerged as a sport in its own right in France in 1902. Cyclo-cross bicycles are similar to other bicycles, but the frame geometry is closer to a mountain bike than a road racing bicycle. The top tube is often longer and closer to horizontal, and the handlebars are higher, again akin to mountain bikes. The emphasis on bicycle handling skills differentiates cyclo-cross from road racing. Cyclo-cross courses are held on a variety of terrain, including grass, mud, sand and paved surfa ...

Hybrid Bicycle
Hybrid bicycles blend characteristics from more specialized road bikes, touring bikes and mountain bikes. The resulting "hybrid" is a general-purpose bike that can tolerate a wide range of riding conditions and applications. Their stability, comfort and ease of use make them popular with novice cyclists, casual riders, commuters, and children. Hybrids typically borrow the flat, straight handlebars and upright seating posture of a mountain bike, which many bicyclists find comfortable and intuitive. Hybrids also employ the lighter weight, thinner wheels and smooth tires of road bikes, allowing for greater speed and less exertion when riding on the road. Hybrid bikes often have places to mount racks and bags for transporting belongings, much like a touring bike. Hybrid bikes have spawned numerous sub-categories satisfying diverse ridership. They are classified by their design priorities, such as those optimized for comfort or fitness — and those offered as city, cross or commu ...

City Bike
A utility bicycle, city bicycle, urban bicycle, European city bike (ECB), Dutch bike, classic bike or simply city-bike, is a bicycle designed for frequent very short, very slow rides through very flat urban areas. It is a form of utility bicycle commonly seen around the world, built to facilitate everyday short-distance riding (no more than 3-4 miles a day) in normal clothes in cold-to-mild weather conditions. It is therefore a bicycle designed for very short-range practical transportation, as opposed to those primarily for recreation and competition, such as touring bicycles, racing bicycles, and mountain bicycles. Utility bicycles are the most common form globally, and comprise the vast majority found in the developing world. City bikes may be individually owned or operated as part of a public bike sharing scheme. Generally as they are more suitable for urban environments, they focus more on short-distance comfort and practicality instead of speed or efficiency. They norm ...

Single-speed Bike
A single-speed bicycle is a type of bicycle with a single gear ratio. These bicycles are without derailleur gears, hub gearing or other methods for varying the gear ratio of the bicycle. There are many types of modern single speed bicycles; BMX bicycles, most bicycles designed for children, cruiser type bicycles, classic commuter bicycles, unicycles, bicycles designed for track racing, fixed-gear road bicycles, and single-speed mountain and cyclocross bikes. Although most fixed-gear bicycles (fixies) are technically single speed, the term single-speed generally refers to a single gear ratio bicycle with a freewheel mechanism to allow it to coast. Vis-à-vis multi-speed bicycles Advantages A single-speed bicycle is generally cheaper, lighter, and mechanically simpler than its multi-geared equivalent. Without derailleurs or other gearing systems, there are fewer parts on the bicycle that require maintenance, making this type of cycle useful for city commuting in all weathe ...

Roller Chain
Roller chain or bush roller chain is the type of chain drive most commonly used for transmission of mechanical power on many kinds of domestic, industrial and agricultural machinery, including conveyors, wire- and tube-drawing machines, printing presses, cars, motorcycles, and bicycles. It consists of a series of short cylindrical rollers held together by side links. It is driven by a toothed wheel called a sprocket. It is a simple, reliable, and efficientAs much as 98% efficient under ideal conditions, according to means of power transmission. Sketches by Leonardo da Vinci in the 16th century show a chain with a roller bearing. In 1800, James Fussell patented a roller chain on development of his balance lock and in 1880 Hans Renold patented a bush roller chain. Construction There are two types of links alternating in the bush roller chain. The first type is inner links, having two inner plates held together by two sleeves or bushings upon which rotate two rollers. I ...
