## Abstract

The present application is directed to motor driven vehicles. In one embodiment the motor driven vehicle is a trike that utilizes a customized three wheel rear truck assembly to create a completely novel riding experience. The rear truck assembly of the motor driven vehicle may be comprised of a skateboard truck and wheels along with a third center caster wheel on a custom caster assembly that allows the center cater wheel to rotate 360° independently from the outer skateboard wheels. The size parts of the motor driven vehicle may be varied in size, such as the wheels and mounting plates thereof, according to the needs of a rider. The center wheel may comprise a bracket assembly that holds the wheel at a fixed distance that is lower than the outer wheels.

## Claims
