US Patent 10384111 Bicycle trainer

A bicycle trainer includes a magnetic control damping device controlling a resisting force of a roller set to simulate stamp strengths required by a bicycle on various roads. A lifting device controls a support frame and a base seat to drive a front fork of the bicycle up or down to dynamically simulate states of the body of the bicycle on various roads, so that the actual effect closest to the bicycle running on an uphill, smooth or bumpy road can be achieved. In addition, a power generation device converts the rotating power, generated by the roller set, into the electric power for the dynamic simulation or other electronic devices.
