    地亦有「腳踏車」一稱;在香港,澳門,廣東,廣西, “中國南方地區則更常稱為為”單車“;在新加坡,馬來西亞,廣東潮汕地區則稱為”腳車“,江西贛語更稱之為”線車(甩)“,”鋼絲車“ “腳踏車嘚”。


    A bicycle, often called a bike or cycle, is a human-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 19th century in Europe and as of 2003, more than 1 billion have been produced worldwide, twice as many as the number of automobiles that 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 for use as children's toys, general fitness, military and police applications, courier services, and bicycle racing.

    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. But 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.
