PROBLEM TO BE SOLVED: To provide a power generation method and a power generation and recognition device of a bicycle, capable of lighting a light emitting diode by surely generating electric power even in bicycles f various forms and during low-speed traveling.SOLUTION: A suction magnet assembly 8 having a magnet is fixed to a spoke 4 of a wheel, and a plate is provided, on the other hand, in a power generation magnet assembly 10 having a magnet repulsive to the above magnet, and is fixed to a bicycle frame 3 by a band 19 connected to the plate so that positions of both magnets have an optimal interval to a rotational orbit. The wheel 6 rotates, and both magnets approach each other, and when magnetic force of both magnets mutually repulse, the magnets instantly move in the inside of a coil; a high electric current instantly flows to the coil; and a tail end light emitting diode 2 is lighted. When the magnets are separated from each other by the further rotation of the wheel 6, the magnets instantly by pass through the inside of the coil to return to original positions by suction force of the spoke 4 and repulsion of a spring, and the electric current flows to the coil, and the tail end light emitting diode 2 is lighted again by rectification of a bridge diode. |
