1. this trick is very easy once you get used to the weight distribution.
2. you basically just put your front foot on the nose in the same position as your back foot for an ollie and your back foot in the spot you'd put your front foot for an ollie.
3. the trick to doing a nollie is that you have to lean back and push forward as you pop the nose.
4. slide your back foot up and level it out.
5. land and keep rolling just like you did an ollie.
TIP: if you're doing it over or down stuff, you have to pop a little earlier the for an ollie.
