An electrically assisted pedalled bicycle that has a rear wheel mounted on a frame supported elongated axle, a modified freewheel that has an electric motor\s brushes, frame, and field coil windings supported to its body, a commutator and armature that are stationarily fastened to the stationary axle, a battery that is controlled by a manually operable rheostat, and an electric circuit that includes a chain actuated on/off switch, so that when the rheostat is advanced, and the chain is actuated, the circuit goes on, and the rider\s pedalling provides pedal torque to the freewheel sprocket, and while the bicycle is commencing to be propelled, the motor\s brushes and field are rotated about and interact with the motor\s commutator and armature and simultaneously provide a motor torque that is blended with the rider\s pedal torque as it flows to the freewheel sprocket, to thereby assist the rider\s pedalling as it propells the bicycle.
