Abstract
An auxiliary wheel including a wheel hub and a tire, the wheel hub includes an outer wheel hub and an inner wheel hub and the tire is mounted on the outer wall of the outer wheel hub. The outer wheel hub and the inner wheel hub are detachably connected through a first connection component. When the first connection component unlocks the connection between the outer wheel hub and the inner wheel hub, relative rotation is generated between the outer wheel hub and the inner wheel hub with bearings disposed between the inner wheel hub and the outer wheel hub to reduce friction. Friction is reduced between the outer and inner wheels, thereby increasing the upper limit of the auxiliary wheel rotation speed. A nut and bolt arrangement is disposed in the nut groove to firmly fix the ring on the outer wall of the outer wheel.
