In this video, the rider does a surge up to the rear wheel.
Most people who have tried to ride Observed Trials will tell you that learning the basic moves is probably the hardest part of the process. You might spend weeks trying to learn the most basic move, and it will be frustrating, especially if you have no one to ride with that already knows what bike trials is about.
The following videos were shot specifically for this site to show you, as clearly as possible, how the various moves in Mountain Bike Observed Trials are performed. These videos are not always the most "exciting" or "entertaining" videos out there, but they are not intended to be. Someday, you might be able to gapshoot 9 feet to the top of a phonebooth, but most of us need to start with the fundamentals. Hence, these videos.
