Abstract
The invention provides an electric bicycle comprising an electric motor mounted on the body of the bicycle between the saddle and the outer periphery of the rear wheel, and a belt transmission mechanism for transmitting the rotation of the motor to the rear wheel on speed reduction. The belt transmission mechanism comprises a drive pulley provided between the saddle and the outer periphery of the rear wheel for receiving the power of the motor, a driven pulley having the same diameter as the rim of the rear wheel and rotatable with the rear wheel alongside the rim, and a belt reeved around the drive pulley and the driven pulley. These components realize a simple construction wherein the rotation of the motor can be transmitted to the rear wheel as reduced to the desired speed in a smaller number of stages.
