Blizzard Entertainment has released the second episode in its Azeroth Choppers web show, an eight-part series that sees famed motorcycle designer Paul Jr. of American Choppers and his team create bikes based on the Horde and Alliance in-game factions.

Team Horde and Team Alliance are each building their own bikes inspired by the respective factions, but only one will prevail in the end. When both bikes are finished, players will vote to see which bike Blizzard creates a virtual version of to appear as a free mount for World of Warcraft.

It's a pretty interesting, and somewhat surprising, partnership between Blizzard and Paul Jr., who owns and operates New York-based custom-bike shop Paul Jr. Designs. We spoke with Paul Jr. about the project at PAX East and you can read more about that here.

The first installment in the Azeroth Choppers series went live last week. New episodes are available on Thursdays, running through early June. The next World of Warcraft expansion is Warlords of Draenor, which is set to launch later this year.
