The bicycle is the world's most popular form of transport, and its design has evolved over the decades both in terms of style and technology. From high-performance cycles to practical run-arounds, conceptual bikes to commercial models, the bicycle means different things to different people, from a means of transportation to a hobby, a way of keeping fit or for competitive sport. In this book, the Design Museum explores the fifty most innovative and influential bicycles in the world, from the very first Laufmaschine of the early 19th century to the Team GB track bike used by Chris Hoy at the London 2012 Olympics. With stunning photography selected by the Design Museum, Fifty Bicycles That Changed the World is the perfect gift for cycling aficionados and design enthusiasts of all ages.
