Abstract:
1. An improved electrically assisted pedaled vehicle comprising: a frame, seat, handlebars, pedal bars, a pedal bar equalizer chain, an equalizer chain pulley, a modified rear wheel hub having a right hand freewheel thread on its right side, a left hand freewheel thread on its left side, and a large diameter hub body incorporated bushing at the base of each threaded end, a rear wheel having an elongated axle that is round in shape but rectangular in shape near its extreme ends, a hub mounted modified right hand threaded freewheel body having a smooth large diameter surface, a lesser diameter grooved surface, a hub mounted modified left hand threaded freewheel body having a smooth large diameter surface, a lesser diameter threaded and grooved surface, and a still lesser diameter grooved surface, vehicle elements that are correspondingly, flexibly, mounted on each freewheel body, including, a right side of wheel pedal bar having a smooth bearing surface mounting hole and a plurality of V slotted holes drilled and equally spaced along its outboard vertical face, a left side of wheel pedal bar having a smooth bearing surface mounting hole and a plurality of V slotted holes drilled and equally spaced along its outboard vertical face, each said pedal bar supports a flexibly fastened, pawl supporting, bracket that can be slid back and forth, along said bar, by a flexible tape that is connected by one end to bottom extension of said bracket, and by its other end to a hand operable pawl positioning controller, a right side of rear bike wheel, large diameter pedal bar stabilizing bushing having center mounting hole lugs that engage said body grooves, providing a smooth bearing surface for said right side pedal bar, a left side of rear bike wheel, large diameter pedal bar stabilizing bushing having center mounting hole lugs that engage said body grooves, providing a smooth bearing surface for said left side pedal bar, a large diameter left side of bike wheel, freewheel wheel, having center mounting hole lugs, a large diameter left side of bike wheel, freewheel wheel, having center mounting lugs, each freewheel wheel's inboard vertical face having a plurality of radian oriented ratcheting grooves, that are engaged by said pawl, in a ratcheting motion, each freewheel wheel's outboard vertical face supporting horizontally projecting rods that carry coiled wires of a motor field each freewheel wheel's outboard vertical surface carrying a flat, circular, non conducting base plate that supports motor elements including, two flat concentric electric current conducting circuit rings, and a pair of carbon motor commutator brushes, and other motor elements correspondingly, stationarily, mounted, outboard of each freewheel body on said axle, including, a large diameter right side of bike wheel, laminated, structurally framed armature and corresponding commutator unit, having a center mounting hole that corresponds to said axle's rectangular shape, and, a large diameter left side of bike wheel, laminated, structurally framed armature and corresponding commutator unit, having a center mounting hole that corresponds to said axle's rectangular shape, each said armature's inboard vertical face having a bracket that supports (+) and (−) electric current leads, and a pair of hinge lever brushes supported to, said freewheel wheel supported, concentric rings, each said commutator being comprised of two complimentary semicircular, flat, conducting surfaces, mounted on the vertical inboard face of said armature, and configured as a circle, with the ends of one semicircle spaced from the ends of the other semicircle to provide a (+) semicircle commutator element, and a (−) semicircle commutator element, outboard freewheel body support elements including, right hand threaded nuts, and washers, and, outboard freewheel body support elements including, left hand threaded nuts, and washers, and freewheel wheel ratcheting elements, that are correspondingly, flexibly mounted, on each said pedal bar, including: a right side of bike wheel, structural, U shaped, pedal bar mounted, pawl bracket, and, a left side of bike wheel, structural, U shaped, pedal bar mounted, pawl bracket, a right side of bike wheel pawl that is carried by said bracket, and has a flexible, freewheel wheel radian groove engaging, end point, and a left side of bike wheel pawl that is carried by said bracket, and has a flexible, freewheel wheel radian groove engaging, end point, a pawl bracket metal magnetic response block that is disposed, mounted in the bottom of said pawl, a pawl, bracket supported, ratcheting mode disengager electromagnet, a pawl bracket, supported, structural T shaped, pawl bracket stabilizing pin, frame mounted, pawl bracket deployment, tape strip stabilizing guides, tape strips that connect each pedal mounted pawl bracket and pawl to a hand operated, combination, pawl ratcheting mode disengaging, and pawl deployment, electro-mechanical, controller unit, that is mounted adjacent said bicycle's handlebar, and that is used to position said pawl brackets and pawls along said pedal bars, to utilize a momentum, leverage advantage, a battery supported by said bicycle frame, a rheostat motor current supply, controller, supported to said bicycle frame, a pedal bar actuated motor circuit current controlswitch, supported by said bicycle frame, a bracket supported tension spring to apply counter pressure on each pawl bracket to offset tape bracket displacement pressure, and pedalbar brackets to limit the travel of a pawl bracket.
