Once the quaint province of European cities like Amsterdam, cycling is becoming increasingly popular in North American cities. People ride folding bikes to the train, slip through traffic on tricked out fixed-gears, and carry children and groceries on their utility bikes. Commuters are giving up their cars M-F, bike lanes and bike parking are being created, and Talking Head David Byrne has designed arty bike racks for various New York City neighborhoods. It’s healthy for riders and clean for the environment, but is it fun? Amy Walker, who has been at the forefront of the urban cycling trend, knows the answer is "yes." She collects a diverse group of cycling enthusiasts and activists who, accompanied by the illustrations of bike culture artist Matt Fleming, show readers why. They say you never forget how to ride a bike; this helps us remember why we ride.
