I use a tray style hitch-mount rack from 1up USA. First rack I’ve ever loved. In no particular order, the things I like about it are: 1. bike is on/off in seconds, 2. rack makes it easy to do basic maintenance trailside, 3. its 100% aluminum so no rust & lightweight, 4. install/remove rack from hitch in seconds with a simple allen key, 5. rack has zero shake in receiver hitch, 6. expandable up to 4 bikes – takes about 2 minutes to add/remove an additional rack. The rack is a little pricey but I don’t mind paying for quality & convenience.
