A reduction drive including an electric motor disposed in a housing and driving a motor shaft, a Hall Effect sensor adjacent to the motor, a power and control module, and a pinion gear in the housing and driven by the motor shaft. A planetary gear reduction assembly includes a first ring gear rotatably disposed in the housing and driven by the pinion gear, a sun gear engaged to and driven by the first ring gear, a second ring gear non-rotatably fixed to a housing surface, and a plurality of planet gears mounted on a carrier assembly, each planet gear rotating with the sun gear, and on the second ring gear. An output axle is driven by the carrier assembly and has an axis of rotation that is offset from and parallel to the motor shaft axis of rotation.
