| An apparatus and method for attaching a wheel to an axle. The apparatus comprises a wheel with a hub (142) for insertion into an indentation in the end of the axle (120) and a single bolt that is offset from the axis of rotation of the wheel and axle and that attaches the wheel (140) to the axle. In a further embodiment, the apparatus comprises a wheel with a hub for insertion into an indentation in the end of the axle and a non-cylindrically-symmetrical stud attached to the axle that is concentric with the axis of rotation of the wheel and axle, thus attaching the wheel to the axle (120). | ||||||

| A system (100) for applying power to rotatable article (104) is provided. The system (100) includes a shaft (102) and a connecting assembly (106, 108). The shaft (102) is capable of being rotated. The connecting assembly (106, 108) engages the shaft (102) with the rotatable article (104). The engagement with the rotatable article (104) is established between the centre and the periphery of the rotatable article (104). | ||||||

| An adaptor for a wheel assembly is disclosed. The adaptor has a reversible design for convenient reconfiguration of the wheel assembly without additional hardware. In one general non-limiting embodiment, the adaptor may include an inner ring and an outer ring fixedly connected to the inner ring. The inner and outer rings may be concentric around an axis. The inner and outer rings may be offset from each other. Methods of using the adaptor to change wheel configurations to accommodate different tire sizes are also disclosed. | ||||||
