Three bike, bike rack. Two inch or one and one quarter inch receiver compatible. Pivot point at bottom to access back of car or truck I without removing bikes and rack. Arms fold down at top pivot point for when not in use. Receiving mount secures tightly and then locks with built in locking mechanism. Built in cable lock to secure bikes to mount. The key (there are two identical keys) for the receiving mount and cable are universal and work on both locks. I’ve used this bike rack for cross country hauls and have trusted it with some of my most prized bicycles. It’s built so well that that it takes all worries off of the mind. Sadly, I no longer have a vehicle with a hitch and therefore no longer have a use for this rack as I transition to roof mounted racks, begrudgingly.
