Abstract: An electromagnetic resistance feedback bicycle training device includes a bicycle trainer frame, an electricity generator, and a resistance feedback system. The electricity generator and the resistance feedback system are mounted on the bicycle trainer frame. The resistance feedback system includes a transmission system connectable to an external electronic device, an electromagnetic resistance generation unit operable to induce an electromagnetic resistance force to a rotating object, a feedback circuit, and a control unit. The control unit detects, by means of an electromagnetic detection element of the feedback circuit, a strength of an electromagnetic field generated by the electromagnetic resistance generation unit, and, in response to the strength of the electromagnetic field, adjusts a level of the electromagnetic resistance force generated by the electromagnetic resistance generation unit. As such, the present invention enables self-generation of electricity and self-supply of electrical power without connection with an external power source and features instantaneous feed-back of electromagnetic resistance force and self-adjustment for maintaining a constant level of the electromagnetic resistance force.
