This glitch is similar to the bike morph glitch in vice city, but it has a limited area that you can use it. In this area you can not fall off the bike, so you can do flips and all other kind of insane stunts. To do this glitch you need:1: Go to the top of Mount Chiliad
2: Get a Parachute (there’s one by the Journey on top of the Mountain)
3: Get on the mountain bike parked at the top of the mountain to start the mission “The Chiliad Challenge”
4: Use the ramp to the left of the beginning of the mission to fly of the mountain. Jump off in midair and open the parachute.If done correctly you should now be morphed with the bike (parachute still open) Now you can do insane stunts without falling of your bike.
