A small correction here, generally the power output of climbers is measured in W/kg, not pure Watts, because their weight heavily influences their ability to climb. I think top climbers have around 7-7.5W/Kg. Even in these conditions, the power output of that motor is orders of magnitude higher than what a human can do.

You're right about the numbers often being expressed in W/kg, because power to weight is more important than power when going uphill. For big climbs (more than half an hour or so), that number is closer to 6W/kg for the best, or maybe a little more (especially if you go back in time a bit for some reason…).
