UPDATE 2/24 9:53 am: Many people have sent updates and well wishes in the comments below. I highly suggest reading them. Also, long-time SBB commenter Leif says Christian is his housemate. He is doing better, but was still unconscious as of this morning.

UPDATE 2/27: Leif has another update on Christian’s recovery and what may have caused the wreck:

Couple updates. First, Christian is still unconscious (at least he hasn’t opened his eyes) but yesterday when a bunch of us were there he did respond to the nurses request for a thumbs up with a very enthusiastic, purposeful thumb in the air. This was the first time he had responded in a way that we were sure was actually him and not just a slight movement. It was very exciting and a good sign that he is moving in the right direction.

…

In terms of the accident, after speaking with the responding officer and the EMT student who was the first responder we are pretty confident that this was a freak accident and didn’t involve any other vehicles. Despite what the police report on the blotter suggests there was actually witnesses who saw him go over his handlebars, likely after something broke off his spokes and got caught in the wheels. It certainly doesn’t change the situation, but it is nice to know that nobody caused this and then left the scene.

Thanks to the folks who helped Christian at the time of the accident, especially the EMT student. We are very grateful you were all there.
