250W continuous is not that much, and very much necessary (and possibly not sufficient) to handle even middling hills.

For reference, 1HP = 735.5W. The worst 50cc you'll find are around 3HP, or above 2100W. Child-class go-karts generally start around 5hp, and the most common engines are the 6.5HP GX200 (or harbor freight's copy).

Go carts don’t go on pavements while talking on the mobile phone.

I don’t mind the power, clearly, only what stupid people do with it.

It is not clear at all, no. You pretty literally assert that 250W is a lot of power

I’ll simplify it for you. 250W is too much for an obnoxious idiot on the pavement.
