I haven't read about anything new in the hub motor arena in a while now.

My mechanical understanding is rather limited. But I recall the bearings ... and tight tolerances on the rotor/stator pairs .. being the issue.

Since hub motors have been around for a long time on bikes and scooters, I thought that the bearing-only-being-on-one-side, for the car hub motors, explanation made some sense.

Maybe the ultra-light overall weight reduces the wear? I'm not familiar with how bearings wear ... but most stuff that is mechanical does not appear to have linear relationships between wear and pressure, or wear and torque, or whatever.

Anyone read anything new on hub motors recently?
