Under the waters of Santa Maria Beach, a standing BMX can be found. This is the only known location for the Ghost BMX to spawn. Most fans believe it to just be a spawn glitch, wherein the game spawns in a BMX rather than a boat. However, there is a small group of people who believe the BMX to be mythical; they back up these claims with other strange objects found around Flint Waters and the Flint Range, including the Ghost Traffic Light. The BMX is usable if the player uses the underwater glitch.
