Liberty City Choppers

Liberty City Choppers is a mission in GTA IV DLC The Lost and Damned. It is given by Jim Fitzgerald to Johnny Klebitz.

Description
Early on you'll get a call from Jim which will become an available mission to you, the first of his series. Jim has a buyer for bikes who's interested in shipping certain kinds over to Japan. The Angels of Death, the Lost MC's major rivals, are in possession of such bikes. Jim wants the two of you to go over and steal the bikes and load them into a flatbed truck.

Walkthrough
You first head to an alleyway to pick up the truck, then make your way to another location to pick up the bikes. All of the AOD bikes (five in total) are parked at one building, the first two in the front near where the truck is parked. After those first two, however, there's some AOD resistance. Jim tells you to phone either Terry or Clay for backup. They arrive on scene in short order and manage to take down a large number of the racist bike gang's forces.

When all enemies are dead, Johnny will tell the backup that he can "lone wolf" the job from this point on. You load the final three of five total bikes onto the truck and head out with Jim as passenger. You're now tasked with driving the stolen AOD bikes back to the alleyway where you originally picked up the truck. Unfortunately, AOD thugs on bikes will be in pursuit of you for most of the way back. Upon arriving successfully, you'll witness a cutscene. It shows two crooked FIB agents trying to blackmail you and Jim into paying them off so they don't turn you in. They've been watching The Angels of Death for a while and watched all of your killing and theivery go down. Once they've kicked over one of the stolen bikes and made their point clear, they leave and the mission ends.
