Most manufacturers of e-bike hub motors and/or manufacturers of e-bikes with hub motors say that hub motor is "not serviciable". Their warranty period is typically 1-2 years and servicing the hub could void the warranty. But some manufacturers like Wired and Marsant's recommend routine maintenance and even show you how to do it. The maintenance consists of opening the hub/motor, cleaning it and greasing the clutch/gears. The gears can even be replaced if they are worn or damaged, that is IF you can find a compatible replacement. If your hub motor is frequently exposed to moisture and it is out of warranty, you might want to consider having it serviced.
