I'm looking for feedback on the new Bafang M630 motor. Specifically, I'm wondering if it would be a suitable fit for the WW Ultimate Commuter Pro frames and how well it performs in that application.
I'm currently on my second and third M620 motor rebuilds, as they seem to require major work after only about 6,000 miles. My first M620 failed due to an electronics issue, and upon disassembly, I found the pawl had stripped a significant number of teeth on the inner main gear. The motor I replaced it with now has a nasty grinding sound while pedaling, and I suspect the bottom bracket/axle is the cause.
That motor also recently experienced intermittent torque/pedaling detection failures and surging after being ridden in the rain, though that problem eventually resolved itself. Consequently, I no longer trust the M620's weather resistance—a significant issue for a primary commuter vehicle.
I use only pedal assist (never the throttle) and have not modified the motors for increased power. Given the nearly $800 cost per motor and the high price of replacement parts, this is becoming frustrating. Repairs are also costly and time-consuming; I can't find e-bike mechanics for less than $100 per hour, which, when combined with parts and extended downtime, doesn't make financial sense.
