ABSTRACT:
An "all terrain" scooter is provided with a large central tubular chassis having two central brackets supporting a platform. At the rear, the tubular frame is offset to one side of the chassis for cantilevered support of the rear driven wheel. From this portion of the frame, an engine is pivotally mounted on a pivot arm at a pivot point offset from the axis of rotation of the driven wheel. This engine has a protruding driving shaft overlying the driven wheel for moving into and out of contact with the ground contact surface of the driven wheel. The pivot point of the pivot arm is offset relative to a line between the point of contact of the protruding driving shaft and the center of driven wheel rotation. This offset is in the direction of driven wheel rotation at the point of contact of the protruding driving shaft and causes increased driving contact with required increased scooter driving force. A derailleur cable rachet and cable connection acts against both a spring biasing the protruding driving shaft into the driven wheel and the vector force. This derailleur cable rachet and cable precisely controls and limits engine and protruding driving shaft pivotal contact with the driven wheel. As a consequence of this precisely limited pivotal action, precise driving control between the driven shaft and protruding wheel occurs to enable corresponding precise control over scooter propulsion.
