2,400W is around (and possibly more than) what the strongest track cyclists can sustain for about five seconds.

Tour de France cyclists racing up mountains generally sustain around 400W, which is enough to go 25+km/h for hills that aren't too steep.

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…).
