A wheel module (2) in accordance with the invention includes a wheel (4). A tire (5) is shown fixe to the rim of the wheel (4). A stationary brake caliper (6) is shown fixed to a stationary motor housing (26). In this embodiment, the motor housing (26) is non-rotating structural unit. The brake caliper (6) is operable connectable to a brake disc (8). The brake caliper (6) and brake disc (8) together comprise a brake system (9). The brake caliper (8) is operatively conneted to hub (10). The hub (10) is affixed to the wheel (4) by use of a bolt (11). A rotor unit (12) including rotor discs (14, 16) is rigidly mounted to the hub (10). A stator (18) is shown operatively connected to the motor housing (26).
