A bicycle, or bike, is a pedal-driven human-powered vehicle with two wheels attached to a frame, one behind the other. First introduced in 19th-century Europe, bicycles evolved quickly into their familiar, current design. Numbering over 1,000,000,000 in the world today , bicycles provide the principal means of transportation in many regions and a popular form of recreational transport in others.
The bicycle is one of the most notable of human inventions. The basic shape and configuration of the frame, wheels, pedals, saddle and handlebars has hardly changed since the first chain-driven model was developed around 1885, although many important detail improvements have been made since, especially in recent years using modern materials and computer-aided design.
A remarkable aspect of the bicycle is its widespread adoption in many different fields of human activity, e.g. as a child's toy, in adult recreation and fitness, as a means of everyday transport, in cyclo-touring, for use in many cycle sports, and as a basis for static gymnasium or home fitness versions.
