Nice, I didn't know the SA 3 speed was available with a drum brake.
By room between the BB and motor I mean- the Bafang motor is a fixed distance from the BB shaft (when in place and motor gear engaged with sprocket gear) and designed to clear a small diameter BB. With the larger diameter American BB there may not be enough space when you center it in the adapter you intend to use. I hope I'm wrong.
