I am helping my uncle with his Ohm e-bike which comes with BionX equipment and I'm having trouble. I only other experience is with a Crystalite setup.
The motor is on the rear wheel and the axle twisted out on one side yesterday. He stopped riding immediately and I found the wiring wrapped less than one time around the axle. I think the wiring will be ok.
The axle is smaller diameter than the C-lite axle but what really suprised me is that the axle was not slotted. The BionX axle is round and there was a thick washer like thing on the axle with a off-set nub thing on it that looks like it is supposed to prevent the axle from turning around.
The problem is the Ohm frame is aluminum and IMO is pretty soft. There are thread marks in the rear drop out and the nut holding the axle has cut into the frame.
I'm kinda bummed out about the whole thing because I don't see how this setup will ever tighten up again enough to keep the axle from twisting out again...without some "creative engineering" and jury rigging on the frame.
My uncle is 70+ and rides the bike very, very gently and he weighc about 160 lb.
The BionX is probably a great motor/setup but I am very disappointed in the Ohm e-bike frame and mounting setup.
How does the BionX kit mount up on bikes? Is the axle slotted for the dropout or is it a totally round axle? Do you use it on aluminum frames?
Thanks for any help/suggestions.
