This is a tutorial on how to levitate in GTAIV.
Settings: Race (Recommended); Motorcycles (Required); The NRG Motorcycle; 2 People (Minimum)
Tutorial (Text, Sorry No Video):
1.) At the start, go off course into an open intersection.
2.) Burnout your tires by holding down the brake and the accelerator at the same time.
3.) Once your tires are burnt off, keep accelerating in an EXACT circle.
4.) To do an EXACT circle every time, simply push the right stick directly to the left/right.
Note: You cannot see yourself floating. Only your friend(s) can. This is simply for fun. I do not know if I am the only one who found this. Me and my friends found it but there could be other people that found it before us.
Thank you,
