Abstract
A lever drive system for a scooter including a crank arm having a first distal end pivotally carried on a frame and operatively associated with a drive sprocket, wherein reciprocating movement of the crank arm causes rotation of the drive sprocket for moving a drive chain operatively associated with a wheel assembly. A footrest is disposed on the crank arm for operating the crank arm. A cam member is pivotally mounted to the frame generally adjacent the crank arm. A cam follower is carried by the crank arm engaging the cam member, wherein movement of the crank arm causes the cam follower to move along a contoured control surface of the cam member for controlling an up and down movement of the crank arm.
