Abstract
Abstract A velocipede having swingable rear wheel mounts controlled by the steering of the velocipede so that on turning the front wheel of the velocipede the swinging rear wheel mounts are swung oppositely to cause the velocipede to bank in the same manner as the bicycle is banked in making a turn. The velocipede rider is thus trained in the motions a bicycle will make on turning to assist in preparing him to ride a bicycle.
