Indeed, two-wheeled electric transport is pretty great! It's a mix of EVs and bicycles proper.
These devices still need parking, even if they are as compact as a scooter or a bicycle (not like a motorcycle). Keeping them in an apartment is a bit uncomfortable, too, especially in a walk-in on 4th floor, since they are not exactly lightweight.
Electric skateboards are much more compact, but take more skill, and have a shorter range.
All this is totally solvable, but the problems first needs to be recognized.
