February 12, 20206 yr Author Keep your busted controller as a side cover - it’s good for waterproofing if nothing else. You get the chance to hollow out the guts of the controller too, which is a cathartic experience External controller placement is a problem - I use a hailong downtube battery that allows a controller to be installed within in the battery holder, avoiding water ingress problems. Hmmmmm, I have already hollowed out the old controller as I was going to replace the caps with better quality ones, but on getting through the potting compound I found the whole thing had a little bit of fire damage. I also have a battery in a Hailong case, so might look into it a bit more now.
February 12, 20206 yr I have and use a gear sensor. I think it's just the fact that derailleurs are not made for torque electric motors and legs put through them. we are going back to hub versus cranks debate. In fairness, a hub gear would equally stick if you don't take off the pressure on the pedals when changing gear.
February 12, 20206 yr some people are born with mechanical sympathy and some people constantly break things.

That's why I'm disappointed Conti discontinued their ebike Division as their motor and gearbox looked like what I imagine the future will be.
