bicycle, two-wheeled steerable machine that is pedaled by the rider's feet. On a standard bicycle the wheels are mounted in-line in a metal frame, with the front wheel held in a rotatable fork. The rider sits on a saddle and steers by leaning and turning handlebars that are attached to the fork.

A bicycle (or bike) is a small, human powered land vehicle with a seat, two wheels, two pedals, and a metal chain connected to cogs on the pedals and rear wheel. A frame gives the bike strength, and the other parts are attached to the frame.

A bicycle, also called a pedal cycle, bike, push-bike or cycle, is a human-powered or motor-assisted, pedal-driven, single-track vehicle, with two wheels attached to a frame, one behind the other. A bicycle rider is called a cyclist, or bicyclist.

The Bicycle as a symbol of progress, of renewal, of promising times ahead. This is not a new concept. Indeed it has been around since the invention of the bicycle. Many bicycle posters at end of the 19th century featured promising themes like liberation, progress, freedom.
