I do own a direct drive hub motor (VIVANA LE250RH, Nanfong Leisheng Special Motors Co Ltd. ) that runs at 300rpm @ 36V and weights 3.06kg incl. mount for a cassette and option to mount disc brakes. 36 spoke holes though, which sadly excludes most lightweight rims.
Sadly my motor has an axle grinded down to 8mm instead of 10mm, so I have not been able to try it yet.
I doubt that it would be wise to ride it at 2500W+. The cogging is rather low, so I assume that maximum torque will be quite low, too.
I assume(!) that geared hub drive systems in that weight class deliver a lot more torque, but I doubt that they will tolerate 2500W+ either.
