$9000 will buy a heckuva motorcycle.
800 watts aint nothin compared to a regular motorcycle.
It's also kind of overkill for something that's designed like a bicycle. The bike's probably really nice, if you're in to that sort of thing at that sort of price, but $9000 could also buy 3 or more really nice bikes with even higher power crystalyte hub motors.... but nobody sells those fully assembled.
