Velocipede \Ve*loc"i*pede\, n. [L. velox, -ocis, swift + pes,
   pedis, a foot. See {Velocity}, and {Foot}.]
   A light road carriage propelled by the feet of the rider.
   Originally it was propelled by striking the tips of the toes
   on the roadway, but commonly now by the action of the feet on
   a pedal or pedals connected with the axle of one or more of
   the wheels, and causing their revolution. They are made in
   many forms, with two, three, or four wheels. See {Bicycle},
   and {Tricycle}.
