Well, that's only part of it. The 2nd District Illinois Appellate Court (which is the district that presides over cases out of the collar counties) just upheld a police officers ability to arrest a cyclist for violating a municipal ordinance. In this case, the cyclist was arrested for riding on the sidewalk and riding without a head lamp. The court ruled that violations of even these minor infractions was enough to fully arrest somebody and take them to jail pending the posting of bond (similar to domestic battery or DUI).
Synopsis of case:
"Trial court did not err when it denied defendant's motion to quash arrest and suppress evidence seized after police officer stopped defendant for driving a bicycle on sidewalk at night without a headlamp, defendant indicated that he had neither a driver's license nor money to post as bond, police officer discovered drug pipe on defendant's person when he searched him incident to arrest, and booking officer discovered bag of controlled substance when defendant pulled his socks down at police station. There is no requirement that police officer actually issue citation to defendant in order to conduct proper search incident to arrest or take defendant into custody; and procedure complies with SCR 526(a)."

Looks to me like if Barrinton Hills really wants to rid their town of cyclists, it won't be hard.
