OK, assuming there is some sort of unusual resistance, it would seem to me that you could tell mechanical from electrical with simple power on/power off tests? Maybe turn the bike upside down and see if the rear wheel "coasts" differently power on/off? Difficulty to turn the crank power on/off?
In the bold, struggling with what you are saying. "Faster than the motor"?It's fine coasting, brakes are not binding, wheel hub is ok.
Coasts fine with power on and off, just under pedal power a lot of resistance from bafang unit. You can feel it with low Pas mode you are going faster than the motor

"A lot of resistance" as compared to what? A non e-bike equivalent? If that's the case, wondering about your expectations. Do you believe that this conversion should be as easy to pedal as a non powered bike? That comparing the 2 is realistic?
If you can't feel that "extra" resistance on the flat and level, you need to turn up the power a bit more for the hills.I expect resistance but not so much literally you cannot pedal uphill on pedal power due to massive amount of resistance.
It's not the extra weight I've carried more weight in rucksack, trailer etc.
