PURPOSE: A bicycle with an environmentally-friendly auxiliary power device is provided to improve the driving convenience of a passenger by using the rolling power of the passenger and solar energy as the driving power of the bicycle. CONSTITUTION: A bicycle comprises a body frame, a main power device(120), an auxiliary power source generating part(150), and an auxiliary power device. The main power device comprises pedals(121), a first driving sprocket(123), first driven sprockets(125,125'), and second driven sprockets(127,127'). The pedals and first driving sprocket provide rotating force to a rear wheel shaft(115). The first driving sprocket, first driven sprockets, and second driven sprockets are connected by a first power transferring chain(129). The auxiliary power source generating part provides power source for rotating a rear wheel and has supports(140) and solar panels. The auxiliary power device provides the rotating power to the rear wheel by using the power source of the auxiliary power source generating part. |
