Where are all the Electric Maxi-scooters?

I do enjoy my Honda Silverwing scooter but I keep thinking its time for a Electric vehicle. Especially seeing how it currently wouldn’t pass the new London ultra low emission zone and frankly its time for more environmental focus.

I remember looking at scooters to hire in Berlin, thinking where the disc breaks and will car drivers actually see you on such a small thing? But at the other end there are electric motorcycles like the new Harley Davison livewire. But theres little in between.

What is needed is maxi-scooters which are electric powered surely? However I have had such a hard time finding them.

The closest I can find is the BMW Cevolution
