Today marks the release of Bikers, a big new free DLC for GTA Online. Lots of new content in this one including Motorcycle Clubs, Clubhouses, Businesses, 13 new vehicles, 5 new weapons, loads of new clothes and tats, and a new adversary mode. Probably best to let Rockstar go into detail about all that so check out the Newswire article for more info on that. Trailer below.
