I also don't believe that there is ANY state that requires a citizen to provide ID simply because a police officer asks. They have to have a reason and that reason, at a minimum, has to meet Terry standards. Whether the suspicion is being an illegal alien, a thief or whatever, no police officer can require ID from somebody that is simply walking around and I think that's true of biking around. And IF a state made such a law it would very quickly be found to be unconstitutional. That's what I think and you'd have to quote the state and the statute to convince me otherwise...Always happy to learn...
