The invention discloses a self-generating device of a bicycle. The self-generating device of the bicycle comprises a generating box and magnetic field devices. The generating box and the magnetic field devices are of split structures, the magnetic field devices are fixedly installed on spokes of a wheel, the generating box is fixedly installed at the position, corresponding to the magnetic field devices, of an axle, the position, relative to the magnetic field devices, of the generating box on an axle is adjustable, a generating coil, a rectifier used for rectifying the generating coil, and a rechargeable battery used for supplying supplementary power outwards are fixedly installed in the generating box, the power supply output end of the generating box is in electrical connection with a headlight of a bicycle body and a backlight of the bicycle body. According to the invention, the generator magnetic field part is directly installed on the wheel, the generating coil is independently installed on the axle, so that the structure is simplified, the use is more flexible, the part, protruding out of the bicycle body, of the axle is used ingeniously, the generating box is installed simply and rapidly, a transmission part is omitted, magnets are directly fixed onto the spokes of the wheel and move along with the spokes, thus the problem of friction is not caused, the bicycle body is portable, the running resistance of tyres is small, components are not easily worn and torn, and the service life is long.
