1.) - Try a manual (a wheelie on your back wheels) and see how far you can go. To do a manual, just lean back while you move only a little bit. You will soon get the hang of it.
2.) - If you can do a manual, then it's time to learn the 360 manual (a 360 on your two back wheels) Ride in a manual then as you start slowing down, rotate your body backwards until you get around to a 360. This trick takes a little practice, but once you get the hang of it your ready for the Ollie.
3.) - Ahh, the Ollie, the most performed trick around and certainly the most important. The ollie is pretty fun to do, because you can always get a lot better at it. Ride at a normal speed, then put your back foot on the tail, and your front foot in the middle. When your ready, push down on the tail fairly hard and slide your foot that is in the middle up towards the nose. You should have lifted right in the air! (*note: this trick is easier to learn by standing still on flat ground or on the grass)
