"Bicycle" includes, but is not limited to, a human-powered vehicle designed to transport by the act of pedaling which has more than two wheels when the vehicle is used on a public roadway, public bicycle path, or other public road or right-of-way, but does not include a tricycle.
it reads that a " bicycle "includes" other human powered vehicles with more than 2 wheels",,,,, which means you can have a 4 wheel bike and its still a bicycle .... i would jus t take it easy when on the streets of alabama,,, i havent had any trouble "yet" .. but i watch every where and stay on side roads and shoulder lanes when i can ,,,, but that doesnt mean motors are leagle now .... if its got an engine in alabama you are required to tag it ...... sorry but wish it wasnt that way ....
