The Zombie is a Harley-Davidson styled motorbike featured in GTA IV. The motorcycle resembles a custom Harley-Davidson with a rigid body frame, as evidenced by the lack of a separate rear suspension module. The engine is a chain-driven, two-cylinder V-Twin internal combustion engine with a manual transmission, as evidenced by the "suicide shift" style foot-actuated gear shifter. The Lost Zombie sports an oversized carburetor on the right side of the engine. Both variants of the Zombie have elongated "cruiser" type handlebars, which make cornering difficult with the increased sweep caused by the handle arms.
Manufactured by Liberty City Choppers, a parody of Orange County Choppers, the Zombie is a favourite of the Lost Brotherhood biker gang. The Lost Zombies can be distinguished by the red rims on the wheels, custom pinstriping on the gas tank, and a jolly roger on the gas tank lid. The Lost Zombies can be found in Acter, near Gracie Ancelotti's house, but are quite rare. Whilst able to reach a decent top speed, the handling suffers from the oversized front tire, and the bike is susceptible to oversteer.
