(625 ILCS 5/1-140.15 new)
Sec. 1-140.15. Low-speed gas bicycle. A 2 or 3-wheeled
device with fully operable pedals and a gasoline motor of less
than one horsepower, whose maximum speed on a paved level
surface, when powered solely by such a motor while ridden by an
operator who weighs 170 pounds, is less than 20 miles per hour.
Essentially what it's saying is: a low speed gas MB is any bike with a gas motor and pedals(without pedals everything is considered a motorcycle, pedals are a must to skirt the below 150cc motorcycle licensing laws.), with a motor rated below one horse power(if you're involved in an accident with major injury/property damage/death trust me they will check what motor you have and manufactures specs so putting a 48cc magneto cover on your 80cc bike only gets you so far), and the bikes maximum speed when powered just by the motor is less than 20 mph when ridden by a 170 pound rider on a paved level surface.(not sure if they would expect you to go much slower than 20 if you were a 6'2" 240#'s like me but really top speed isn't affected a whole lot by weight, that's more of a gearing/rpm thing.)
To qualify as a gas powered low speed bike a bike must fit all 3 criteria:
1.)pedals
2.)less than one horsepower
3.)Cannot be capable of exceeding 20 mph on a level paved surface with a 170 pound rider
