Not meaning weirdo eccentric individuals but changing 24mm axle cranks for use on Ebike motors.
I've a new set of Rotor rex bike cranks that have a spider(for 2x10) and a 24mm axle. It looks like the spider and axle could come off, i dont know if the axle is pressed in, but i dont think so, but the question applies to any cranks especially 1x ones.
So could it just be a matter of freeing the crank arms from the 24mm spindle(axle), taking off the spider and fitting the crank arms directly to the motor interface ?
The rotor arms are considerably lighter and better quality than the FSA CK-745 cranks that came fitted. The only other difference is the rotor cranks are 175, though I hope that wouldnt make any real difference, but if it does it does and I could put up with it given im pretty tall and usually ride 175mm.
Or is this just not possible and the crank arms need to be specific for ebike motors
Motor is a Bosch perf CX gen4
