Bike

Bike vehicles feature as enemies in the Borderlands 2 DLC, Mr. Torgue's Campaign of Carnage. The bike is a motorcycle with a sidecar attached. Each one has a front mounted weapon that defines which type of bike it is, and a sidecar. The rider operates the forward weapon, while the sidecar passenger is free to use small arms.

Boom Bike
The boom bike is armed with a forward firing rocket launcher. This weapon fires a salvo of three rockets with every shot and is slow to reload.

Grinder Bike
The grinder bike has a ram plate affixed to the front and is ridden right up to targets to initiate melee attacks. Against a stationary target vehicle these blades will continue to worry the structure of the target while the two vehicles are locked together.

Road Gunner
The road gunner comes equipped with a vehicular shotgun. The weapon operates in the same manner as personal shotguns, and has a fairly inaccurate spread of buckshot.
