I weigh 180 lbs and can push roughly 7,000 watts. I know this because I work in an industrial facility and once had to attach my bike to the 10hp rotary-screw air compressor when the electric motor blew out (real 10hp, not the Sears inflated kind). I was on the bike for roughly 13 hours. It was a good workout but nothing to write home about.

882 watts is easily doable.
