Kids

Cambridge Bicycle and Boston Bicycle carry children's bicycles frombicycles from Diamondback, Fuji, and Jamis.

Most kids try a two-wheeler with training wheels around age 3 years. Between ages 4 and 8 years most kids develop sufficient skill to ride without training wheels, and sufficient hand strength to safely use hand brakes instead of a coaster brake.

Adult bikes are sized by the frame (measured from the center of the bottom bracket to the top of the seat tube). Bikes for children are sized by their wheels: 12”, 16”, 20” and 24”.
