It wobbles, had to replace fold up pin with a 5/8" x 2 1/2" bolt with nylock nut. Tighten both the new faster and the pivot bolt snuggly. The seat post strap assembly can slide off the upright if left loose w/o a bike, I installed a very small self teck screw at the end of both uprights. The ramp flops around in the storage receptacle badly, I put one wrap of gaffers tape on the ramp post. Lastly I installed "Conspicuity " tape on the ramp to improve visibility for vehicles following. Otherwise I love the rack.
