You may get a small amount of nitro when you land a flip. The more flips you do, the more nitro you will get. When nitro is used you will get a noticeable speed boost, but may increase the chance of a crash. When have a safe path ahead, tilt your device left slightly bit to raise your bike. You will do a wheelie and continue to move forward. You will crash if you tilt too much. You can get a lot of nitro by doing this because this trick does not require you to catch air.
