Florida Law
I'm a law student in Florida and I did a little research into the legality of the 50cc engine bikes to see if I had to register it. I still don't have an answer for that question, but I did run into the following case: District Court of Appeal of Florida, Fourth District. STATE of Florida, Appellant, v. Antonio MANCHADO, Appellee. No. 4D07-30. Nov. 21, 2007. Citation is 968 So.2d 115, if any of you happen to be lawyers or want to check it on Westlaw or Lexis at the courthouse.
In this case, Mr. Manchado was charged with felony drunk driving as he was a habitual offender. He was caught driving a 50cc engine powered bike that didn't go faster than 30mph. Florida appeals court sent him to jail saying the following:
"The vehicle at issue falls within the definition of a motor vehicle in chapter 322 as it is self-propelled, not operated upon rails or guideway, and does not fall within any of the exclusions as it is not moved solely by human power nor is it a motorized wheelchair. Sec. 322.01(26), Fla. Stat. Manchado did not allege that the vehicle fell within the exception for motorized bicycles. A motorized bicycle by definition is not capable of exceeding a speed of twenty miles per hour, whereas here it was alleged that the vehicle could not exceed thirty miles per hour. Sec. 316.003(2), Fla. Stat. Because the vehicle is self-propelled *117 and not excluded from the definition of a motor vehicle, Manchado was required to have a license in order to operate it. "
Motor Vehicle Definition from
Sec. 322.01
(26) "Motor vehicle" means any self-propelled vehicle, including a motor vehicle combination, not operated upon rails or guideway, excluding vehicles moved solely by human power, motorized wheelchairs, and motorized bicycles as defined in s. 316.003.
then the referenced section
Sec. 316.003
(2) Bicycle.--Every vehicle propelled solely by human power, and every motorized bicycle propelled by a combination of human power and an electric helper motor capable of propelling the vehicle at a speed of not more than 20 miles per hour on level ground upon which any person may ride, having two tandem wheels, and including any device generally recognized as a bicycle though equipped with two front or two rear wheels. The term does not include such a vehicle with a seat height of no more than 25 inches from the ground when the seat is adjusted to its highest position or a scooter or similar device. No person under the age of 16 may operate or ride upon a motorized bicycle.
Our bikes may best fall under the definition of Mopeds as defined here but I really don't know.
Sec. 316.003
(77) Moped.--Any vehicle with pedals to permit propulsion by human power, having a seat or saddle for the use of the rider and designed to travel on not more than three wheels; with a motor rated not in excess of 2 brake horsepower and not capable of propelling the vehicle at a speed greater than 30 miles per hour on level ground; and with a power-drive system that functions directly or automatically without clutching or shifting gears by the operator after the drive system is engaged. If an internal combustion engine is used, the displacement may not exceed 50 cubic centimeters.
