@EverydayMoggie asks:
E-bike motors are not very reliable; it seems that about 25% of them fail pretty quickly.
Q6. If you have an e-bike, have you had trouble with the motor?

my 1st e-assist:
2010: StokeMonkey #cargobike specific. Simple 3ph dc hub motor driving stoker side of a 3x tandem crankset. Unstoppable, bulletproof. pull stumps, sipped power.
2020: horrible winter. had to store bike outside under plastic. 1ph on motor failed, water instrusion, 4 miles from home in freezing rain & snow with a load. sucked, bigly
motor EoL'd in 2015, shoulda bought a spare when I could.
alas.

replaced (I was in a rush, I *need* my bike!) with a Tonsheng TSDZ2
modified with a double chainring.
wasn't great(?), no where near as much torque as the StokeMonkey, but I did really like the torque sensing drive. Used far more battery power.
It lasted almost exactly 3 years.
Have since learned I did pretty well. Even 'real' factory oems don't reliably last much longer.

Current drive system
Bafang BBSHD canbus, again modified with double chainrings
I flatly outright reject 1x drivetrains for #cargobikes
The StokeMonkey allowed crawling grades at 2mph while sipping power for help.
never got hot
none of these systems do that.
but none can be geared down low.
had to go to 48v from 36v to use it.
But, it's been 'ok'
I can get the work done.
also
good reputation.

epilog:
fwiw
folks have explained that my StokeMonkey's beating heart, the Crystalite 806 isn't dead at all.
it's just sleep'n!
I did pack it away, and all the bits.
&
given time & assuming I can actually *find* it(!),
I can take it apart, clean it, test & replace whichever diode failed, press in new bearings, and put it back into service.
&
I may do that.
it is exceptional.
