That's a 90Nm motor according to the spec sheet which is somewhat realistic for 1000W hub. Unless it's got a torque arm, you need every bit of clamping force you can get to keep that axle from rocking or spinning out under load. This is controlled by the nut surface area and material. If there's no torque arm, I wouldn't fuck with it.
thank you! this was the answer i was hoping to find. there's no torque arm, so I'll stick with carrying two wrenches.
as an aside, does anyone have any recommendations for cranksets for a '92 rockhopper? it's got shimano biopace on it (what it came with) which is now warped after years of abuse, and I'm hoping to turn that into a commuter for the days I don't like taking the ebike.
In order to avoid having to remove the rear wheel often, I'd buy a rear tire with really good puncture protection. I had an episode when I had to remove my rear hub several times in a month because I used Panaracer GravelKing which turned out to have really weak protection. I switched to a version with protection and I haven't had to remove my hub due to punctures.
Not familiar with the bike but what could it be - square taper, ISIS? Not sure if ISIS is that old. If it's square taper, there's plenty of options. The lower end Shimano cranks (Alivio, Acera) used to use square taper. They probably still do.
Looked at a pic of Biopace, looks like square taper.
