This book gives a glimpse into the trials and tribulations of inventing, developing and perfecting the art of pedal-powered transport over the years from the the original 'hobby-horse' velocipede to the the notorious bone-shaker, and from the grand but tricky penny-farthing to Graeme Obree's world-beating home-made suprbike. This second edition has been updated to take in Chris Hoy's amazing three gold medals in the 2008 Olympics.
