Do they have bike rentals? If so, how much are they?

They absolutely do rent bikes for riding in the bike park at Bryce resort. Not sure on cost but I think Jake's answer is about right.

Yes they do. It was 150 to 175. Sounded like best package was 160 with lesson.

I don't think so. They never did in the past. Not really any safe areas to ride. Narrow berms on roadsides and just enough room to dive on the roads.
