From what I recall power... well torque is not the problem.
Power is just 'torques' x rpm after all.
4 bog std Chinese hub motors, in rims, have 1400Nm from 0 rpm!
Enough to pull a train!

If you're talking hub power or unsprung weight per kg; well that's a different story.
A light motor is generally a weak motor.
But these guys seem to have decent numbers.
