  • Variable speed drive shaft bicycle
    Patent number: 5522612
    Abstract: A bicycle for converting reciprocal human motion into linear vehicular translation. The inventive device includes a frame supported relative to a ground surface by front and rear wheels. A pedal assembly converts user pedaling into rotational torque output through a pedal shaft extending vertically through the frame. A first transmission receives torque from the pedal shaft and couples with a drive shaft extending through the frame. A second transmission couples the drive shaft to the rear wheel such that the vehicle can be accelerated by an individual.
