ABSTRACT:
A spring drive and a spring drive scooter for use by an operator. The spring drive and spring drive scooter have a frame, a resilient member connected to the frame, a pedal, and a movement. The pedal is supported by the resilient member. The pedal is disposed to bear the operator. The pedal is capable, together with the operator, of oscillatory motion relative to the frame in response to at least roughly periodic impulses supplied to the pedal by the operator at a range of frequencies including a resonant frequency. The movement is connected to the frame and includes a final driven member. The movement is actuated by reciprocation of the pedal, the movement is capable of converting oscillatory motion of the pedal into circular motion of the final driven member.
