A wheel assembly for a vehicle comprises a hollow support cylinder extending along an axis and anchored to a frame of the vehicle, and a wheel disposed about the axis, annularly surrounding the hollow support cylinder. The wheel comprises an inner wall and a tire extending radially outward of the inner wall, and anchored thereto. The wheel assembly further comprises first and second sleeve bearings disposed between and abutting the hollow support cylinder and the inner wall, the first sleeve bearing being situated proximal to the frame along the axis, the second sleeve bearing being situated distal to the frame along the axis, and the wheel being rotatably supported on the hollow support cylinder via the first and second sleeve bearings. The wheel assembly further comprises a first direct drive motor disposed axially between the first and second sleeve bearings. The first direct drive motor comprises a first wound stator anchored to the hollow support structure, and a first permanent magnet rotor anchored to the inner wall, axially aligned with the first wound stator and radially outward of the first wound stator.
