Got a priceless FYI tip for everyone.
The motor on Fred's bike ran backwards when I first hooked it up in the default config.
Super simple to correct the problem by connecting the blue & yellow main motor/controller phase wires together.
Just connect blue motor wire to the yellow controller wire, & the blue controller wire to the yellow motor wire.
You also ''must'' have to,, ''carefully'' remove the yellow & green connector pins on the Hall sensor harness connector, & swap those positions in the connector,, then you are good to go !!
If you ''just'' swap the phase motor leads like on a R/C brushless motor,, you can smoke the controller & motor.
The controller on the O'l lady's bike has a self learn system in it ,unlike Freds controller.
All you had to do there, is momentarily touch the 2 self learn wires together that come out of the controller.
Only have to do that though if it initially runs backwards, ours didn't.
