A bicycle is a pedal-driven land vehicle with two wheels attached to a
frame one in front of the other. First introduced in 19th century
Europe, it evolved quickly into its current design. With over one
billion in the world today, bicycles provide the principal means of
transportation in many regions and a popular form of recreation in
others. The bicycle has had considerable historical impact, in both
the cultural and industrial realms. In its early years, bicycle
construction drew on pre-existing technologies, while more recently
bicycle technology has contributed in turn to other, newer areas.
Beyond recreation and transportation, bicycles have been adapted for
use in many occupations, in the military, and in sports and
entertainment as well. A recurring theme in bicycling has been the
tension between bicyclists and drivers of motor vehicles, each of whom
argue for their fair share of the world's roadways.
