For improving electric generation stability of an automatic start generator in a 180V storage battery output circuit, an excitation triode G2 is added based on a voltage stabilization triode G1 so as to amplify power and provide an enough current to a relay. When a storage battery normally supplies electricity, the voltage stabilization triode G1 enters a saturation region, and does not work. When voltage of the storage battery is lower than a set value, the voltage stabilization triode G1exits from the saturation region, and enters a work state, and simultaneously a collector electrode of the voltage stabilization triode G1 couples a signal into the excitation triode G2 through a coupling capacitor so as to perform power amplification, and provides an attracting current to the relay so as to achieve the purpose of enabling an electric generator to automatically start generating electricity. Electricity of the storage battery is output to an electric bicycle load circuit as positive electricity through a forward diode G3. When the electric quantity (voltage) of the storage battery is lower than the set value 165V, the electric generator automatically starts generating the electricity, the generated electricity is output to the storage battery as a direct current about 10A through a diode G4, and a diode G5 outputs a direct current up to 100A to the electric bicycle load circuit so as to provide energy needed by a 180V electric bicycle.
