@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?

The eBike Motor Reliability Crisis β€” Here Are 3 Motors You Can Trust

@ascentale @EverydayMoggie @bikenite #BikeNite A6. I note that the data presented cover only mid-drive motors. It doesn't look to me like any hub motors are represented.

Futhermore, eMTB motors are, as the author notes, subjected to far higher stresses and potential abuses than motors used on the streets, so I wouldn't even count that data, at all.

Nor does there seems to be any differentiation of failure modes. Mid-drive motors have complex electronics mounted inside their cases.

@ascentale @EverydayMoggie @bikenite One thing this video did impress upon me, however, is that mid-drive motors have problems with seals, and water ingress seems to be the primary culprit in failure.

Because of the problems with Rad Power Bikes potentially going out of business entirely, I have been planning for my next ebike to be a custom build using a Bafang BBS02 750 W mid-drive system, since Bafang seems to be the most popular and widely available retrofit.
