They are similar to the controllers offered by Bolton and Electro Bike World, but are quieter and more efficient, which is exactly what I'm looking for.
However, they are not plug and play, and come with collection of different connectors. However I'm good with soldering and figured everything out, except for the hall effect wiring. Do the Bafang motors use a standard color scheme for the 5 hall effect wires? I cannot seem to find a reliable wiring diagram.
450 to 750 dollars to remove the motor hum. Looks like a lot of trouble and cost to me. I would contact Rad for a wiring diagram. Good luck.

Some of the controllers are less than $100, but the better ones can get up there in price. Sine wave controller are quieter, but also more efficient under load, and some can optimize the electronic angle of the stator coils on the fly. With winter here, quietness is less of an issue at the moment, but it would be nice not to keep switching controllers depending on if I'm riding through silent woods with pedestrians, or need all 1,600 watts for mountain bike trails.
