Here is a video of a bike ride I would love to do but there are a few moments that would make me nervous as all get out.
This is in Chile and it is a downhill run on a mountain bike! The few spots that make me nervous would be the first set of stairs with the dog and ramp, then the transition jump at 2:27, then the final jump that you really have to time right otherwise your history!!
Anyway click on the toolbar and make it full screen to get the real thrill out of it!!
