A central Illinois appellate court made a ruling; the 20 mph begins when the motor takes over from the pedal start. If you pedal to 13 mph, you are allowed a 20 mph boost to 33 mph in my opinion of the ruling. There are 5 appellate districts in Illinois and this ruling only clearly applies to the Decatur district. However this could be a strong enough argument to be accepted by other areas in Illinois. I have talked to my town police chief in northern Illinois and without reviewing the ruling, accepted it as a local rule of law. I ride down main street in the lane of traffic at over 20 mph without any problem. My bike only goes 25-28 mph and the speed limit through town is 30 mph. I would rather be riding at 30 mph and keep up with traffic. In Illinois, in my opinion, it is important that the bike be seen pedaled from a dead stop without help from the motor to be safe from licensing and insurance issues. I use both dual pull c brakes and the coaster brake at the same time to stop the beach cruiser. Riding over 20 mph could be a local privilege that may be gone if something is hit with the bike. I am attempting to post the pdf of the Decatur Appellate ruling 2012 4110593_R23 as posted in the Laws and Legislation section of Motorbicycling.com; but the attached file or link are not appearing in this preview. I carry a copy of this ruling when I ride to make this argument if I am stopped; which has not happened yet.
