Welcome to the forum.
Check the forum here on Laws and Legislation
first. There's probably something helpful in there.
I did a quick google of "new orleans motor vehicle definition" and got this link
. I don't know if it's the right document to start you off or not, but under definitions, it reads "(41) "Motorized bicycle" means a pedal bicycle which may be propelled by human power or helper motor, or by both, with a motor rated no more than one and one-half brake horsepower, a cylinder capacity not exceeding fifty cubic centimeters, an automatic transmission, and which produces a maximum design speed of no more than twenty-five miles per hour on a flat surface."
I don't know where to point you from there, but go fishing with Google and you should find out what you need.
