On my old Surly Long Haul Trucker, the motor had been working fine. But it started to lose power temporarily. Almost like a shift sensor motor the stop. Sometimes the motor would lose temporary power and stop. It happened at unexpected times and seemed to have a gear shift happened at the same time. I thought it might be a faulty shift sensor, so I cleaned that and used de-electric grease for all the connections.
The issue continued so it could be a good time to replace the rear cluster and chain. It had been a while, and the chain was showing some wear. But that did not resolve the issue.
So the next move was to replace the motor controller.
As I was setting up to change the motor controller, I thought it was a good time to a re-greasing of the motor. So when I was checking the motor for how it was looking after 5,000 miles, I noticed a crack around the bottom bracket. The frame was beyond repair. And maybe, just maybe, that crack had be causing the flex in the shifting was impacting the sift sensor that was shutting off the motor.
I remove the motor from the bottom bracket because the long haul trucker frame was gone.
But at least the motor looks good (see video below) and will not wait for a new Bike to go into.
The motor re-greasing went well and I went ahead and changed the motor controller while I had it all apart. the motor should be good to go for the next bike.

(inspection and ready for re-greasing of a BBS02 motor after 5,000 miles)
