A Track Mule, also known simply as a Mule or COG Bike, was a series of motorcycles that were produced at some point within the history of the Coalition of Ordered Governments, capable of carrying two passengers and performing exceedingly well on both pavement and rugged off-road terrain. They had wide tires and no cover or windshield, allowing for the second passenger to provide fire support for the driver. Mules could also endure several large jumps at maximum speed without major structural damage.

The Track Mule differed greatly from the Rat Bike, as it was structurally different and lacked any apparent hard points for an onboard weapons system or sidecar.


By 42 A.E., Track Mules were commonly regarded as antiques. Two Track Mules were acquired and maintained by Marcus Fenix at some point following the end of the Locust War. They were later used to escape hostile COG DeeBee forces at the Stroud Estate before making their way to Fort Reval to investigate the disappearance of the missing Outsiders, inevitably leading them to discover the Swarm. During this escape, Marcus Fenix, along with JD Fenix, Kait Diaz and Delmont Walker were able to take down a large COG gunship, the Vulture.
