I think this situation just sounds like everyday, garden-variety crazy. I bet he's got nothing in particular against cyclists. He might have taken a swing at a car that came too close.

You're absolutely right. I've worked on psych units for 30 years and I've been coldcocked a number of times.
Pain is not a good weapon when you're dealing with a psychotic person. Inflicting pain before he hits you won't stop him because he's so agitated. Inflicting pain after he hits you is just taking revenge on a sick person, and not cool.
Walk away. If that doesn't work, push him away from you very hard, then turn and run away. A psychotic person will almost never follow you, since they usually just want to be left alone.
