Best legal conversion kit by far!Expensive

The UK law is vague...max 250w and a 15.5mph limit (25kmh call it speed A). But to get up a steep hill that same motor will be pulling far more watts, maybe 3, 4 or 5 X the rated power...example to get up a 10% hill the motors maybe pulling 500w+ at speed A...but only 175w on level ground at speed A......at what point is the motor illegal? The law doesn't and cannot define this...plus power IN is not the same as power OUT.....like having your foot down in a low powered car on a hill, you foots down to the floor, the fuel going in is high.....but your speed aint changing. And there is no laws as far as I know about changing the parameters of the motor as long as its rated at 250W from the manufacturer.
