Weirdo physics have been a part of BMX bicycle operation in Grand Theft Auto V since its release, but in Grand Theft Auto Online it's taken on a new dimension lately.
Not only do you soar in moon gravity off Mt. Chiliad, you can even ascend, as this video -- one of dozens uploaded over the past four days to YouTube -- illustrates.
Basically, you have to ramp the bike off a very, very high point and then lean all the way back. You then "fly" the bike, not necessarily like parachuting but sort of like a plane without the tail. As you can see in this video, this glide isn't even the longest among the three guys who were playing together.
