Mekgineer's Chopper

Mekgineer's Chopper is a motorcycle mount created by top Alliance engineers. This vehicle allows one party member to ride along in the sidecar. It's one of the few mounts that can be bought on the Auction house, however it will usually cost plenty of gold, considering the price of the mats to create it.

Activating the sidecar
To activate Mekgineer's Chopper's sidecar and carry a passenger, simply invite the player to a group. The player's pointer will turn into a green mounting arrow when they mouse over Mekgineer's Chopper, allowing them to jump on while the sidecar deploys itself automatically. Note that if you are in a raid group, your passenger must be in the same group (1, 2, 3...etc) as you to enter the side car.
