I'd be interested on the sheaths. Cable ties look tacky.
I ended up using my one pound mallet with the stock Bafang tool. I hammered until it quit moving.
Routing the sensor cable was a pain, it had to lie where it wouldn't cause the brake cable, and itself from getting wrapped up. Also the brake and shift cables can no longer be run through their stay welded on right behind the bottom of the motor, it required too much of a bend and I damaged my cables and had to replace them.
