I just worked on a bike that was left out in the rain for a series of Winter storms. The owner told me initially that the wire to the speed sensor rubbed on his tire and shorted. He tried soldering but it still didn't work so the bike would shut down every five minutes. Okay, I fixed it so it would show speed again. But it wouldn't go. WTF? I ran diagnostics. Nothing conclusive. I reset everything to factory default and then reprogramed everything. Nada. Then I tried turning off the torque sensor so it would be a cadence only bike. That worked. So, it is the torque sensor. That is buried in the middle of the motor. It takes six hours of intense highly skilled work and it is really easy to mess up, like to crimp a little wire. Small engine mechanics charge $250 per hour around here but this is a much bigger and higher skilled job. I told him the it is easier to replace the motor and I would provide a new one with free labor at half price. When I removed the original motor it was all rust. It was mostly junk and looked like it sat on the bottom of a saltwater bay. I showed him and was able to get retail for the motor and provided free labor. If you love your bike don't leave it in the rain. IP-65 is very good, but it is not a dive watch.
