The law is out of date. e-bikes are just cycles under the road transport act, electric scooters are 'mechanically propelled vehicles' - i.e. just like cars and trucks.
In theory a scooter would be legal on roads if you could convince the DfT you met the safety regs, had a type certificate, license plate, VIN etc - it would still be illegal to use on a bike lane and I don't know that anyone has managed to do this!
