I am amused this is still a topic of discussion in America.
Visit China sometime, electric motor scooters (larger than the kids versions we have here[1]) and motorbikes are everywhere, the large majority of small vehicles on the road there are now electric.
It is super nice, the streets are far cleaner and quieter than just a few years ago.
One huge benefit China has is an existing infrastructure for smaller vehicles, there is either a grade separation or a fence that differentiates small vehicles from larger ones.
On narrow urban streets speeds are lower so the separation is not needed. This is actually a great example of how making streets smaller can increase throughput, if bikes + electric bikes + motor scooters + cars all share the same road, more traffic can fit on the street once people who would be in individual occupancy cars feel comfortable moving to more space efficient forms of transportation.
Meanwhile in America we paint a tiny narrow bike lane on the road and pretend the white line is going to stop accidents.
Bonus: Electric motorbikes / motor scooters can have canopies on top, helping alleviate some of the weather issues.
