A motorized apparatus for towing a wheelchair includes a framework, a handle assembly, a motor driving assembly and a wheelchair connecting assembly. The framework includes a chassis. The handle assembly is adjustably mounted on the chassis. The motor driving assembly is mounted on the chassis and includes a wheel assembly with a single wheel rotatably mounted on the chassis, a combined clutch and brake assembly connected to the wheel assembly, a motor assembly connected to the combined clutch and brake assembly to drive the single wheel assembly through the combined clutch and brake assembly and a one-hand operated battery assembly coupled electrically to the motor assembly to drive the control unit and the motor assembly. The wheelchair connecting assembly interconnects the framework to a wheelchair. Consequently, the motorized apparatus will tow the wheelchair along a path, road and so on.
