I am planning on installing a x5 motor on my mountain bike that currently has a 9-speed cassette freehub. I am pretty new at this and need some help figuring out what gear cluster to order with my new hub motor. From what I understand, my current freehub will not work on a x5 axel. I have also been told that a 9-speed gear cluster has a different spacing (closer) than any gear cluster less than 9-speed. My chain is also skinnier than a chain that is made for a bike with less than 9 gears. I don't need 9 gears, but I do need a gear cluster with the same spacing between gears as my current setup so that I can use my same shifer and chain.
I hope there is an easy fix for this. Please help.
