If they don't qualify for the "bicycle" label, what are they?

Two wheels.

Two independent axles

It has to have two wheels on separate axles (bi-), and it must be powered through a repetitive motion (the cycle).

Things that don’t meet that are called other things, like tricycle, scooter, moped, motorcycle.

I’ve seen/heard something else being labeled (in traditional media, but I’m sure it’s in online as well) as “e-bicycle”, or a “scooter”, when it’s neither. And it’s not a moped, or a motorcyle, or a tricycle. So, what is it, that’s being mislabled? Edited for typo.
