The bicycle, often called a bike or cycle, is a human-powered, pedal-driven, single-track vehicle, having two tires attached to a body, one behind the other. A new bicycle rider is called a cyclist, or bicyclist.
Bikes were introduced in the 19th century in European countries and as of 2003, more than 1 billion have been produced worldwide, twice as many as the number of automobiles which have been produced. They are the principal means of transportation in many areas. In addition they provide a popular form of recreation, and have been adapted for proper use as children’s toys, basic fitness, military and law enforcement applications, courier services, and bicycle racing.
The basic condition 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 advent of modern materials and computer-aided design. These have allowed for a proliferation of specialised designs for many types of cycling.
The bicycle’s invention has had an huge effect on society, in conditions of culture associated with advancing modern professional methods. Several components that eventually played a key role in the development of the automobile were primarily invented for use in the bicycle, including basketball bearings, pneumatic tires, chain-driven sprockets, and tension-spoked wheels.

The word bicycle first appeared in English print out in The Daily News in 1868, to describe “Bysicles and trysicles” on the “Champs Elys? sera and Bois de Boulogne. ” The term 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 some extent of overlap for a time.
The Eitler pfau (umgangssprachlich) horse, also called Draisienne or Laufmaschine, was the first human means of transport to utilize 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 people in Mannheim in summer 1817 and in Paris in 1818. Its driver sat astride a wood frame supported by two in-line wheels and forced the vehicle along with his or her feet while steering the front wheel.
The very first mechanically-propelled, two-wheeled vehicle may have been built by Kirkpatrick MacMillan, a Scottish blacksmith, in 1839, although the state is often disputed. This individual is also associated with the first recorded instance of a cycling traffic offense, when a Glasgow newspaper in 1842 documented 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 5 shillings.
In the earlier 1860s, Frenchmen Pierre Michaux and Pierre Lallement got bicycle design in a new direction by adding a mechanical crank drive with pedals by using 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 wheels with wire spokes were patented by Eug? eine Meyer of Paris. The particular French v? locip? de, made of iron and wood, developed into the “penny-farthing” (historically known as an “ordinary bicycle”, a retronym, since there was then no other kind). It featured a tubular steel frame 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 Business (which soon became the Coventry Machinists Company), delivered 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.
