For instance i dont understand why ebikes are limited by power of motor when max legal speed limit is set. You cant legally use ebike on road when motor power is more then 250W. If someone think about its weapon, then they should realise its kinetic energy which "hurts". And i never heard about terrorist on bike... Another bullshhh....
Does anyone know why?

Thats only purpose of ebike! Nah.
I am living in area with hills. I just dont want have low power motor. I dont want to be at rated power most of time. So i would rather pickup ebike in kW range. Note i dont want to even ride at 50km/h. Thats to much for bike. 30-40 is safe for me.
 
If you built your own controller then you could exceed the max wattage of the motor for short intervals. You would need to monitor the temperature of the motor to know when you've overheated it.

If the motor runs at 50V then it will draw 5A at max load. If you limit the current to 5A then it won't overheat and will always produce the same torque. How fast you can go uphill will depend on steepness and gearing. Downhill could be hair raising.

So we trust distributor that motor does not overheat on nominal power? I dont.
