ABSTRACT:
The vehicle drive operates with pedal force rotating a cantilever beam. The beam force can be applied rapidly to the drive, increasing the drive force at one point of the beam revolution to overcome an increase in vehicle rolling resistance. The beam force can also be applied at a steady rate to the drive for the full beam revolution when the vehicle rolling resistance is not changing. The rate the beam force is applied to the drive provides the person pedaling the vehicle, bicycle riding or running exercise in one beam revolution. Reversing the pedal rotation also rotates the beam in the reverse direction for vehicular braking.
