It has been a bit since I came back to this project. I did pull the clip to remove the wiring, cut the wires near the board and motor coils, and try to remove the bearing. As best I can tell, the bearing must have heated and/or spun in the casing because any number of the usual tactics I've used...

Oh man, now I need to spend more money! Back in my medical devices days, the company had a camera that could blow up the view to the point where I could identify a fused transistor in an LSI SMT chip. Your rig looks like something I should be implementing. My hands are still solid, but my eyes...

I meant to add this to an earlier post. If it seems like I'm stalling on this repair, I probably am. I'm 72 and my eyesight sucks at best but the reason I'm on an eBike instead of a motorcycle as I have been for more than 55 years is two years ago I was diagnosed with occular myasthenia gravis...

I see the confusion, but what I wrote was "the existence of 3 identically sized white wires (of a total of 9 wires) makes reassembly awkward at best." So, as you or someone noted, 3 large gauge wires and 6 small gauge wires with 3 of those apparently being white (at least as seen from outside of...

That "9-Pin connector and comes on most every low to mid power capable motor" is good for up to 40A? That would be almost 2,000 watts. I guess I'm confused about what power classifications mean with eBikes: low vs mid vs moderate vs high power. I don't see me ever needing more than a 750W motor...

"I only see one white wire. Where are the other ones, and what do they go to?" The six solder connections just above and to the right of where the cable exits the axle are all for the sensor wires (assuming that's what they are) to the motor connector. Could be there is a stripe on those white...

Excellent advice. I have nothing to lose but time, so why not? I've looked at other Bafang hub motors and some appear to use a considerably smaller connector. I wonder if they all have the same connector problem or if some are actually made with a connector that clears the nuts and bearing...

Unless I'm missing something, the manufacturer did not intend this to be a repairable part. The circuit board, pictured, is a ways from a user-friendly serviceable part. The wire exists the motor shaft at 90 degrees on the right side of this picture. Not impossible, but the existence of 3...

I'm not sure what connector Rad Power uses, but the nut and washers are too big to go through the bearing and the ID is too small to pass over the connector. Thanks for your help. This has me sort of stumped.

I've been trying to repair my grandson's Rad Power Mini, after his two years of commuting to work in Minneapolis with minimal maintenance. Turns out the big killer has been the failure of the Bafang hub motor bearing on the freewheel side. Now, I’m trying to figure out how to remove and replace...
