Bicycle Rider

Bicycles are human-powered vehicles with two wheels attached to a frame in a single-file configuration. They were introduced in Europe in the late 19th century and over 1 billion bicycles now exist globally, far exceeding the number of cars. Bicycles are used primarily for transportation in many areas as well as recreation, fitness, sports, and work applications like courier services. While the basic design of modern bicycles has changed little since 1885, materials and manufacturing advances have enabled many specialized designs. The bicycle's invention significantly impacted culture and spurred innovations later used in automobiles.

bicycle, also called a cycle or bike, is a human-powered or motor-powered, pedal-

driven, single-track vehicle, having two wheels attached to a frame, one behind the
other. A bicycle rider is called a cyclist, or bicyclist.
Bicycles were introduced in the late 19th century in Europe, and by the early 21st
century, more than 1 billion were in existence at a given time.[1][2][3] These numbers far
exceed the number of cars, both in total and ranked by the number of individual models
produced.[4][5][6] They are the principal means of transportation in many regions. They
also provide a popular form of recreation, and have been adapted for use as children's
toys, general fitness, military and police applications, courier services, bicycle racing and
bicycle stunts.
The basic shape and configuration of a typical upright or "safety bicycle", has changed
little since the first chain-driven model was developed around 1885.[7][8][9] However,
many details have been improved, especially since the advent of modern
materials and computer-aided design. These have allowed for a proliferation of
specialized designs for many types of cycling.
The bicycle's invention has had an enormous effect on society, both in terms of culture
and of advancing modern industrial methods. Several components that eventually
played a key role in the development of the automobile were initially invented for use in
the bicycle, including ball bearings, pneumatic tires, chain-driven sprockets and tension-
spoked wheels.[10]
