A bicycle, often called a bike (and sometimes referred to as a "pushbike", "pedal bike", "pedal cycle", or "cycle"), is a human-powered, pedal-driven, single-track vehicle, having two wheels attached to a frame, one behind the other. A person who rides a bicycle is called a cyclist, or bicyclist.

Bicycles were introduced in the 19th century and now number over one billion worldwide, twice as many as automobiles. They are the principal means of transportation in many regions. They also provide a popular form of recreation, and have been adapted for such uses as children's toys, adult fitness, military and police applications, courier services and bicycle racing.

The basic shape and configuration of a typical upright bicycle has changed little since the first chain-driven model was developed around 1885. 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 particular types of cycling.

Danny MacAskill, (born 23 December 1985) also known as 'Danny MegaSkill', is a Scottish trials cyclist, from Dunvegan on the Isle of Skye. He works professionally as a street trials pro rider for Inspired Bicycles Ltd.

As of April 2009, MacAskill, who was brought up in Dunvegan on the Isle of Skye, had been practising for more than 12 years. He gave up his job as a mechanic so he could ride full time. He now lives in Edinburgh. In June 2009, MacAskill appeared in the music video for Doves' single "Winter Hill". MacAskill also appeared in a TV-commercial for the new Volkswagen Golf Estate.

The video, set to 'The Wolves' by Ben Howard, features MacAskill doing tricks in an abandoned Scottish iron works. It was created for Channel 4's documentary Concrete Circus.
