What's interesting is Florida's law is almost identical to Texas, but the authorities there have taken a totally different tact. They're harassing the crap out of motorized bicycle riders.I can't imagine you would be high up on any cops To Do list unless you're just acting like a maniac going down the road or spewing smoke out of your exhaust pipe. I would keep my motorized bicycle as quiet as possible as well in Texas. Leave the stock muffler on it. LOL
Anyone that follows my advise and uses the self propelled argument gets their ticket dismissed. Every other defense has been a loser.
