摘要

PURPOSE: A bicycle with an auxiliary power device is provided to provide a user with a muscular motion effect by enabling the user to simultaneously lift up and rotate two pedals. CONSTITUTION: A bicycle with an auxiliary power device comprises a rear hub set and a pedal set. A spring is installed inside the rear hub set. The spring is molded in a coil shape. The rear hub set is composed of a hub spring(0), a hub shell(1), a hub axle(3), a hub axle disk(2), and a hub cap(11). The pedal set has a pedal lifter. The pedal lifter enables a user to lift up pedals using the top of the foot. Additional power, generated when the spring and the pedal lifter are pedaled, is effectively stored and emitted.
