An improved electrically assisted bicycle has rear wheel, right and left, propulsion
elements, each side having a modified freewheel that carries a hand operated electromagnetic-mechanical
pawl, deployed along a pedal bar by a tape connected to a pawl positioning control
box lever, a freewheel wheel with radian oriented grooves in its inboard face,
and the equivalent of a motor back plate on its outboard face, said grooves being
compatible with a ratcheting motion by said pedal bar pawl, said back plate supporting
an electric motor's field coils, current rings, and motor brushes, that collectively
compliment a motor armature, commutator, and current ring brushes, where wheel
ratcheting torque is applied to one side, and motor torque to the other, said bicycle
also having a battery, a controlling rheostat, and a pedal actuated circuit current
on/off switch, so that a rider can manually deploy ratcheting pawls to selected
pedal leverage points on said wheel, while combining therewith, mixed-in applications
of variable motor leverage to achieve greater vehicle efficiency.
