There tend to be two types of scooter sold, one which purports to be an ebike because it has attachable pedals even though you can't actually ride them. They normally have a limiter switch to restrict to 16mph.
Then you get the 1.5kwh ones which go up to 30mph and are sold as needing registration, licence and insurance.
Personally I wish there was better acceptance of electric scooters. They are IMO much safer - battery low down in the floor, wider tyres, better brakes, better lights and indicators. Push bikes aren't really suited to being fitted with batteries and motors because it messes up the weight distribution.
Hopefully petrol mopeds will soon be phased out, horrible things.
