ABSTRACT:
A motortrike designed to allow individuals that use a wheelchair to independently operate it. The motortrike comprises a wheelchair frame assembly that secures onto a motorcycle frame, a movable platform assembly a transmission assembly, a power transfer assembly and a rear wheel assembly. An individual in a wheelchair may ride the wheelchair onto the platform assembly and lock the wheelchair thereon. A threshold ramp assembly is mounted to the rear of the platform assembly to minimize the transition from ground level to the platform member. The individual may operate the motortrike as a motor vehicle while transporting the wheelchair.
