Nope, I was talking about classical scooters,

From my point of view cargo bikes are the two wheel version of trucks/bus, and only suitable for transport inside of city traffic, whereas with the other ones they are as usable as any motorbike.
Why? I ride it even when I have no cargo needs. It is just like a regular bike really. I guess it's harder to drag it up 5 flights of stairs.
I don't think there is really much difference between an electric sit-down scooter and an e-bike except for ergonomics, except where you might get some weird looks - riding an ebike on a 35+mph road, vs riding a scooter on a dirt trail.
But still, google "radwagon 4" as an example of an e-cargo bike(this is what I have). It has way more capacity than a sit-down scooter. I put two (small) kids on it, and about 50 lbs of groceries, which I don't think one could do with a sit-down scooter.
