I like my e-bike a lot, but cleaning the gears and keeping them calibrated can be a PITA. The wheel hub motor is nice because my chain just keeps on giving even after 2300 miles, but I don’t think I’ve ever heard of an internal gear hub combined with a a wheel hub electric motor.
Ebikes.ca has a hub motor with integrated IGH.
