The regs are 250w continuous Peak power can go above this for short periods,
It is the controller that limits the power not the motor . A 250w max power system would be worse than useless .
Most 36v controllers are rated at 250w but with a current limit set around 15a max current limit (fold back current ) so that makes 540w max power a normal everyday viable power output.
The 15mph +/- 10% limit is the only realistically testable part of the specification.

Ahh I see, Thanks for that Emma.
