<p>The present invention relates to an electromotive bicycle. And more specifically, a shaft integrated PMDC motor is installed in the rear of a frame of a bicycle body, wheels and tires are installed in the outer periphery of the PMDC motor, and the electromotive bicycle includes a battery for charging and discharging and a control unit to operate the PMDC motor in acceleration and to charge the battery with electricity generated in the PMDC motor in the deceleration or coasting driving. A rotor cover constituting the PMDC motor rotates directly the wheels so that the electromotive bicycle of the high power can be provided. In addition, it is possible to lengthen the battery life little more longer by installing a generation means which continuously generates electricity to charges the battery.</p> |
