There are all types of statements, like this one:
But I haven't found a thread where someone actually made it work in sensorless.

All I needed to do was swap the Y and G phase and hall wires. Runs great and fast even on 19s. Can't tell how fast as I don't have a speedometer on this bike. So for ~$37 shipped, and a little work, I've got a decent 72V controller. Next phase of testing is to go to 23s and test the cruise control. Hope to get this done today.

The single light orange/brown wire was cruise control on both of mine. Installed a momentary button to ground for it. Ran regen through ebrake lever switches to ground for regen.

That is the motor I have and I tried it with Hua Tong with 18s Lipo and the wheel just stutters, never starts spinning...what mod did you do to make it work properly? I saw the mod to make it work at 50 volts, but am now just thinking to wire my battery for 72 volts if I can get the controller to drive the motor correctly.

No, I mean you have to wire it up. Regen works fine on the 2 I have using 18s lipo.. So does cruise control, and speed limiting switch. And if you want a strong ebrake, so does brake-hi. Regen and brake-hi only work up to about 78V. Go over that and it doesn't work.
cwah wrote:So brake-hi and regen belong to the same white plug? If I plug brake hi, then regen works at the same time?
I've read the ability to use regen via a throttle or a push button. any idea how I can do that?
Thanks for this invaluable help
