I looked up the statutes governing mopeds in GA. You have to wear an approved helmet, but not necessarily a DOT approved one. Apparently the GSP has a list somewhere, but all DOT helmets are ok. Otherwise you should be fine, just obey all traffic rules & don't ride on limited access roads or interstates (no-brainer you say?). That's about it. Georgia's easy (unlike Alabama- what a pain!)
I know that, and you know that...But Georgia sees it differently. The Code of GA makes it pretty plain that if it goes, has two wheels, & a motor under a certain HP rating then it is considered a moped. Personally, I would try the motor-assisted cycle thing if asked, but be sure I know the moped stuff as a fall back position. Either way, in GA they are ok - just wear your helmet.
Under Georgia law, any motorized cycle with an engine of 50cc or less, or an electric motor of 2 brake horsepower or less, that can't exceed 30 MPH on a level surface, is considered a moped. There are other requirements, however, that you find if you dig a little deeper into Title 40. Mopeds are required to have front and rear turn signals, a brake light, a taillight, and a headlight. They also have to have -- and here's a problem -- dot-approved tires. All the other requirements can be easily taken care of, but you can't put moped tires on a bike. I imagine there are regulations involving what type of brakes they have to have as well, though I haven't looked into that yet. So as far as I can tell, motorized bicycles aren't strictly legal in Georgia. Have any of you other guys from Georgia had problems with the cops, and where do you ride?
