Abstract: A learning-aid bicycle includes a main body, a connecting member, and a pedal set. In practice, the connecting member may be detached from the connecting portion of the main body, so that the pedal set is detached from the main body. Thus, the learner, such as the child, may be seated on the main body, with his two feet stepped on the ground, so as to ride and move the bicycle by his two feet, so that the learner may learn how to operate, maneuver, manipulate and balance the bicycle, without having to step on the cranks of the pedal set to ride and move the bicycle, thereby preventing the learner from falling down from the bicycle, and thereby protecting the learner's safety.
