what kind of hitch do you need for a bike rack

All Hitch Sizes: Before you buy a hitch-mounted bike rack, you'll need to know if it will fit the hitch on your vehicle. Most hitches have a 2" x 2" or 1-1/4" x 1-1/4" receiver opening. If the opening of your vehicle's hitch is 2" x 2", any bike rack made for this opening size will fit.
