Thule spare tire bike rack. Fold up arm fits two bikes. Screw mount has a key lock. Includes 2 stabilizer attachments.
We used the bike rack on a Honda CRV spare tire and it worked great in the offset mount position to center it on the car.
Slight rust but it is visual only and does not affect the strength.
$200 new at REI but $100 used on Red Bear Rentals.
