The PED Cycles BMX is a small stunt bicycle familiar from Grand Theft Auto V and GTA Online, with earlier roots in the series. Its link to Grand Theft Auto VI so far rests on a single detail from the second trailer: a missing-bike poster showing a grey BMX pinned to a bulletin board in the lobby of a Vice City apartment complex.
