From suburban sidewalks to city centers, everyone is getting on a bike; cycling offers a cheap, independent, green, and healthy way to explore. While bike tourism has existed for decades, it has never been easier thanks to new urban bike routes, city-sponsored rental services, and easily transportable bicycles.For City Cycling USA, Thames & Hudson has once again teamed up with the sophisticated cycling brand, Rapha Racing, to produce a series of city-cycling guides geared to seeing Los Angeles, Chicago, New York, and San Francisco on two wheels. Each of the four compact volumes--available in a boxed set that includes all four cities--features cycle-friendly neighborhoods, complete with itineraries, cycle maps, and cyclist-friendly sites to visit. These guides are aimed at people interested in casual exploration, but they also include information for hardcore racing enthusiasts. Designed with the cyclist in mind, the information-packed paperbacks will fit into a backpack or back pocket.
