I finally took my ebike for a test ride.

I did the 'Just get a burger' for 45-minutes with a MacFox today. I diagnosed it in seven seconds. It is a failed motor core. It stutters and grinds like hell before it dies.

Here is what happens when BB spacers are not used on a MTB, and the main-gear motor housing is cranked down against the wide chainstay. It worked for one ride. At the next attempt it broke on the driveway. For the price of a new right housing, chainring, and display, I have a new motor. It would be great for a cargo bike conversion.
