Those “bikes” are mopeds and are legally only not classified as such due to ideologically guided stupidity of politicians. It’s no new mode of transport, the only thing that’s had a relatively recent revival due to better battery technology is the electric motor. But a motor is a motor. If I fitted a bike with a newly invented fart powered motor that could propel it to the speed of sound, it wouldn’t be a new mode of transport either, but a motorbike.

They have always put their balls where the money is.

This reads like you fell on your head without wearing a helmet a few times too often.

There isn’t much to figure out. Treat them as what they are: Small motorcycles, and as a consequence, require a license, insurance, mandate helmets, ban them from roadways reserved for non-motorised traffic, and enforce minimal technical standards.
