A hollow cylinder is protruded outwardly from the center of the pedestal, while one or several hollow pipes fixed at the outer edge of the pedestal. A lightening element connected to the bobbin is received in the hollow pipe. The bobbin is positioned between the left and right magnetic pole with which the bobbin integrally fixed at the inner or outer edge of the hollow cylinder. The magnet block connected to the sleeve is fixed on the axle of the wheel. The turning of the wheel makes the bicycle wheel dynamo to generate electricity so as to enable the lightening element. The bicycle wheel dynamo further includes a light-guide pole for illuminating the rim of the wheel.</p> |
