Abstract
The present invention relates to a motorized multi functional twist vehicle assembly that can be operated either by a user's twisting motion or by a motor. The main structure is a seat that also is the car body. In the front portion of the seat is a drive wheel assembly attached to the seat and the rear portion of the seat has rear wheels attached to the wheel shaft. The rear wheels have a wheel shaft and a clutch gear slideably attached to the wheel shaft. The clutch gear can be moved so as to engage and disengage a drive gear that is attached to a power motor assembly. A switching lever that controls the clutch arm is located on top of the seat. The meshing of the two gears can be done easily with the switching lever. In addition, the exact placement of the clutch gear and the drive gear for connecting and disconnecting can be achieved by the clutch arm or any other means of limiting the motion of the clutch gear.
