Cycling is the use of bicycles, or - less commonly - unicycles, tricycles, quadricycles and other similar wheeled human powered vehicles (HPVs) as a means of transport, a form of recreation or a sport. It is done on roads and paths, across open country or even over snow and ice (icebiking).As a sport, cycling is governed internationally by the Union Cycliste Internationale in Switzerland (for upright bicycles) and by the International Human Powered Vehicle Association (for other HPVs, or human-powered vehicles). Cycling for transport and touring is promoted on a European level by the European Cyclists' Federation, with associated members from Great Britain, Japan and elsewhere. Regular conferences on cycling for transport are held under the auspices of Velo City; global conferences are coordinated by Velo Mondia.Mountain biking grew in the late 20th century, including recreation and racing. It emphasises riding special cycles with high gear ratios over rough paths, special obstacle courses or directly cross country. While very popular as a sport, it has also been criticised for damaging the countryside.Shortly after the introduction of bicycles, competitions developed independently in many parts of the world. Early races involving boneshaker style bicycles were predictably fraught with injuries. Large races became popular during the 1890s "Golden Age of Cycling", with events across Europe, and in the U.S. and Japan as well. At one point, almost every major city in the US had a velodrome or two for track racing events. However since the middle of the 20th century cycling has become a minority sport in the US whilst in Continental Europe it continues to be a major sport, particularly in France, Belgium, Italy and Spain. The most famous of all bicycle races is the Tour de France. This began in 1903, and continues to capture the attention of the sporting world.The physical exercise gained from cycling is generally linked with increased health and well-being. According to the World Health Organization, physical inactivity is second only to tobacco smoking as a health risk in developed countries, and this is associated with many tens of billions of dollars of healthcare costs.[10] The WHO's report[11] suggests that increasing physical activity is a public health 'best buy', and that cycling is a 'highly suitable activity' for this purpose. The charity Sustrans reports that investment in cycling provision can give a 20:1 return from health and other benefits.[12] It has been estimated that, on average, approximately 20 life-years are gained from the health benefits of road bicycling for every life-year lost through injury.One concern often expressed (both by non-cyclists and some cyclists) is the thought that riding in traffic exposes the cyclist to higher levels of air pollution, especially if he travels on or along busy roads. This has been shown to be untrue, as the pollutant and irritant count within cars is consistently higher,[29] (presumably because of limited circulation of air within the car and due to the air intake being directly in the stream of other traffic).Bicycles were first developed in 1817 and have long since been used as a form of transport. Originally, the front wheel was much larger than the rear wheel, and the rider was elevated a great deal, making them difficult to control and very dangerous. In 1885, J.K. Starley of England devised the more modern bike with a chain and gearing to allow the wheels to be of equal size. Although bicycle races had been held on the old "penny farthings", the new bikes stimulated the growth of bicycle racing as a sport.Bicycles were first developed in 1817 and have long since been used as a form of transport.
