I have a Bafang front hub motor on my Sam Hillbirne with instrumentation and control by Grin Tech iof Vancouver, BC. With PAS as well as throttle, I can travel 28-36 miles on my 36V / 14.5 Ah battery. I have an anti slip lever attached to the front axle to retain the motor in my front dropouts. So far, I've found it to be a smooth set up. Grin does a good job with technical assistance.
