What you are asking for does not exist!! You can get a pocket rocket or an electric scooter – but they’re not going to be dependable – and they’re not going to do well with a big guy on there!
They’re illegal on the streets anyway, and you’re not allowed to ride street legal scooters untill you’re 16 (even if a license is not required, you have to be 16).
