System, including apparatus and methods, for transporting cargo using a swing-away hitch adapter that mounts to a hitch of a vehicle and provides a movable hitch receiver for a cargo carrier, such as a rack for carrying bicycles. In some embodiments, the hitch adapter may comprise a fixed beam and a movable beam. The movable beam may be pivotally connected to the fixed beam at a first end and associated with a movable hitch receiver at a second end. A latch mechanism of the adapter may be configured to automatically lock the movable beam in an open position orthogonal to the fixed beam, to provide access to a rear of the vehicle, when the movable beam is pivoted about a pivot axis to the open position from a closed position parallel to the fixed beam.
