Replacing the hub motor 48v 1000w
I have an electric bicycle. Unfortunately while i was riding it the hub motor wheel came loose off the fork and the wire coming out of the hub motor twisted. I have purchased a new hub motor and would like to ask for instrucitons of how can i replace it. I will also try to fix the damaged one if possibile.
thanks for your help.
It sounds like replacing it would be a matter of rebuilding the wheel (re-spokeing). This is easier if the replacement hub is the same diameter as your original.
Depending on your skill-set (have you ever built a bike wheel?), repairing the existing hub would be about the same difficulty; you'll need to split the case and inspect to see what was torn up with the torque.
You can open up the hub and solder wiring or replace wiring. It's not hard. I have posted instruction on how to open a hub in Wilderness Energy in reference to brushes replacement.
If there is alot of busted spokes, it's easier to just buy a new hub and rim w/spokes. You can sell old motor. The reason I say this is that respoking is not easy ( for me) when it is several spokes.
