Abstract

The bicycle is provided with a direct current electric motor 12 of the brush type with permanent magnet stators, which can be supplied with two voltages by connecting it in series S or in parallel P with accumulators. The motor is fixed in an oscillating way on a pin 22 whose axis lies in a plane Y-Y parallel to the median plane of the wheel on which the traction roller 14 acts, the said plane Y-Y essentially coinciding with the centre of gravity G of the motor to which a plate 18 is fixed. This plate can assume two angular positions, under the action of an elastic member 28 and an opposing cam 36, to bring the roller 14 into the active or disengaged state. The surface of the roller has grooves and projections in a helical pattern in order to minimize the wear on the tread of the tyre. <IMAGE>
