The bicycle, often called a bike or cycle, is a human-powered, pedal-driven, single-track vehicle, having two wheels attached to a framework, one behind one other. The bicycle rider is known as a cyclist, or bicyclist.
Mountain bikes were introduced in the 19th century in The european countries and as of 2003, more than 1 billion have been produced worldwide, twice as many as the quantity of automobiles which have been produced. They are the principal means of transportation in many regions. They also provide a popular form of recreation, and have been adapted to be used as children’s toys, general fitness, military and law enforcement applications, courier services, and bicycle racing.
The basic form and configuration of a typical upright or “safety bicycle”, has changed little since the first chain-driven model was developed around 1885. But many details have been improved, especially since the associated with modern materials and computer-aided design. These have allowed for a proliferation of specific designs for many types of cycling.
The bicycle’s invention has received an enormous effect on society, in conditions of culture along with advancing modern professional methods. Several components that eventually played a key role in the development of the automobile were at first invented for use in the bicycle, including golf ball bearings, pneumatic tires, chain-driven sprockets, and tension-spoked rims.

The word bicycle first appeared in English print in The Daily Information in 1868, to explain “Bysicles and trysicles” on the “Champs Elys? ha sido and Bois de Boulogne. ” The word was first used in 1847 in a French publication to describe an unidentified two-wheeled vehicle, possibly a buggy. The design of the bicycle was an progress on the velocipede, even though the words were used with a point of overlap for a time.
The Snob horse, also called Draisienne or Laufmaschine, was the first human means of transport to use only two wheels in tandem and was invented by the German Baron Karl von Drais. It is considered to be the modern bicycle’s forerunner; Drais introduced it to the general public in Mannheim in summer 1817 and in Paris, france in 1818. Its riders sat astride a wooden frame supported by two in-line wheels and pressed the vehicle along with his or her feet while steering the front wheel.
The first mechanically-propelled, two-wheeled vehicle could have been built by Kirkpatrick MacMillan, a Scottish blacksmith, in 1839, although the claim is often disputed. He or she is also associated with the first recorded occasion of a cycling traffic offense, when a Glasgow newspaper in 1842 noted an accident through which an anonymous “gentleman from Dumfries-shire… bestride a velocipede… of ingenious design” toppled a little girl in Glasgow and was fined several shillings.
In the early 1860s, Frenchmen Pierre Michaux and Pierre Lallement took bicycle design in a new direction by adding a mechanical crank drive with pedals with an increased front wheel (the velocipede). Another French inventor named Douglas Grasso had a unsuccessful prototype of Pierre Lallement’s bicycle several years earlier. Several inventions followed using rear-wheel drive, the best known being the rod-driven velocipede by Scotsman Thomas McCall in 1869. In that same year, bicycle tires with wire spokes were patented by Eug? ne Meyer of Paris. The particular French v? locip? de, made of iron and wood, developed into the “penny-farthing” (historically known as a possible “ordinary bicycle”, a retronym, since there was then most kind). It presented a tubular steel body which were mounted wire-spoked wheels with solid plastic tires. These bicycles were challenging to ride due to their high seat and poor weight distribution. In 1868 Rowley Turner, a sales agent of the Coventry Sewing Machine Company (which soon became the Coventry Machinists Company), brought a Michaux cycle to Coventry, England. His granddad, Josiah Turner, and business partner James Starley, used this as a basis for the ‘Coventry Model’ in what became Britain’s first cycle factory.
