Wattage numbers can be exaggerated by the vendors as well...
I doubt the Chinese vendor's motor is a true 800-1000w unit.. Those alone usually cost at least $150..
I would bet they're just using a controller that will put out 50a, and that's where they get the 800w figure.

48v is a good amount of voltage, for small hills.

I'll check out the price for you..
I'll tell you, I've purchased from this vendor since early last year and the motors are still running well.
They are bafang motors, that much I know.
(he's purchased $20,000 of stock in the past 2 years)
