1. A motor for applying a rotational force to a wheel, the wheel having a rim rotatably mounted to an axle about a first axis, the motor comprising:
a rotor coupled to the rim and having an interior cavity and a plurality of radial slots,
a cylindrical stator disposed within the cavity and having a second axis offset from the first axis, the stator being fixed in rotation relative to the axle;
a plurality of vanes, each vane being slidably disposed within one of the plurality of radial slots; and
a compressed gas source in fluid communication with the cavity, wherein the compressed gas source selectively provides compressed gas to the cavity to rotate the rotor.
