« on: July 03, 2018, 07:39:12 PM »But having the bearings in my motor fail around 10k miles points out a serious flaw in their design for long term use ... at least in a motor with exposed internals and with 10 kN higher tension above stock![]()
So while the bearings were subject to near constant axial forces they didn't experience sudden jolts a wheel would experience. That said ... if they were such a bad idea for wheels then they wouldn't be able to sell them nearly as much as most motorcyclist are cheap bastards who flinch when they have to replace a 0.10$ part![]()
I'm in the sad position where my motor bearings seem to have worn out. There are 2 reasons for me to suspect this. Firstly there is a slight noise coming from the motor and secondly I'm able to slightly move the pulley up and down by hand. Plus the motor doesn't feel as punchy as it used to. My local Zero dealer have proven themselves to be a bunch of scamsters, so I'm left to my own devices. Is there anywhere that I can find more motor info? Is it even possible to replace the bearings yourself, or do I need to find electric motor specialists?
