Brands and sources??
I think about system parameters and features first.
Regen or no. Sine wave, square wave or new wave?
I am more of a new world music guy so being harmonics what they are I would go New wave all the way
Thanks for the humor !
After talking with my electrical engineer buddy he says you really need a scope to test phase wires to the motor , which is beyond my knowledge at the moment. As a mechanic guy the hub doesn't scare me it's more spare time right now and not wanting to open the hub if it's fine. Since eeryone suggests having a spare controller and throttle I am doing just that.
I did send my controller back to Lyen, he has been very on top of it and I am waiting to hear back.
After talking with Grin.ca , they say their controllers do not play nice with the high rpm BMC motors I have decided to get a back up controller directly from BMC. Other bike shops source them but add on almost 100.00 which might be due to there own modifications, but I hope it comes from BMC just as the pic shows, plug and play for a CA V3.
Thanks again for the responses

What Voltages, LVC, if so where?
Amps, display connectivity and programming?
If you bike is "DIY", what steered you to the controller that is being used now?
Does it meet your expectations, or is it lacking somewhere?
Give us some specifics and then sensible recommendations can be made.
If it's what you still want, why not buy the same thing as a replacement?
The argument that a spare controller is needed really only applies to those who's Ebike is their sole commuter transpo.
These days, I can get the controllers I use in less than a week and I can live without my bike for that long.
