This is mainly a UK / Europe focussed cycling forum albeit with a few beloved American (and other) members, so knowledge of GA's scooter law might be thin on the ground. Googling will turn up better results I feel.
Spending seemingly half my life in Atlanta it does appear from widespread scooter use there that the laws are far, far more permissive, that's regarding sidewalk and road use. We can't use e bikes without pedals here in the UK for instance, that would be classed as a moped which would require licence, insurance, helmet etc.
Best to ask your local DMV or City police I'd think.
