After a lull in new GTA 5 cheat discoveries, a Redditer has shared a new code to spawn a BMX. We've tested the code and it spawned a silver BMX.

Xbox 360 Code: Left, Left, Right, Right, Left, Right, X, B, Y, RB, RT

PS3 Code: Left, Left, Right, Right, Left, Right, Square, Circle, Triangle, R1, R2

As with all previously discovered GTA 5 cheats, Achievements will be deactivated during a session with active cheats.

A number of cheats remain undiscovered, including invincibility, give weapons and super jump.
