Disassembly of an RH212 Direct Drive Ebike Hub Motor

This video shows the process for opening up a typical direct drive ebike hub motor for service and repair work with the use of a gear puller. The process is very similar for most of the direct drive hubs currently on the market, although a few manufacturers like BionX and TDCM tend to use a press-fit on the motor shell instead of fasteners. (see https://youtu.be/Wc8OJtFRUng?t=170 )

Without a gear puller you can usually still open the motor by using your body weight to push on the rotor while the axle is against the floor. We don't recommend using flathead screwdrivers or small crowbars to 'pry' the side covers off as it is very easy both to dent the surface of the aluminum plats and also to nick and sever copper wires in the stator.
