For an invention with a history of just 200 years, the simple bicycle has changed the world in many ways, offering transportation and sport to millions of people worldwide. In this illustrated survey, Tom Ambrose retraces the evolution of the bicycle by telling the stories of 50 iconic machines, including the Boneshaker, which had wheels made of wood and iron; the Coventry Lever, an early tricycle for adults; the Funiculo, a pioneering mountain bike; and the BSA Paratrooper, an efficient fold-up used by soldiers on D-Day.
