I put these bikes together, and I have one myself. I live in Montana, and they don't seem to have a problem with it here. What everyone seems to be missing, is it was already decided in the supreme court that federal law triumphs State law, in regards to Medical marijuana, no less.
Federal law states that a bicycle with a 49 cc motor or less is not considered a motor vehicle, therefore does not need to be licensed or registered. Also, it is human powered, because you have to pedal it to start it, so it basically has the same rights as a bicycle, even to the point of having the right to ride on a non motorized bike path. It is classified as an assisted vehicle, just like a motorized wheelchair, or E bike. So, states like Florida, or Arizona actually don't have the right to ban them, the Federal government has already classified them as a non-motorized vehicle, having the same traffic rights as a regular pedal bicycle. They are NOT a motorized vehicle according to Federal statures.
Most of us actually have a 66 cc motor. Mums the word. Stand up to the state of Florida on this issue, Yankhpan, you have the right to ride your motor assisted bicycle according to Federal stautes.
