Swagman 2 bike hitch mounted bike rack. Model is XTC2 (link here: https://www.swagman.ca/products/xtc2-hitch-mount?_pos=12&_sid=274649b4d&_ss=r).
Flips down for the trunk door, adjustable for all bike sizes.
Used once or twice then sat in the basement. Really secure but I prefer a bike with an engine. Retails for $225, selling for $75.
