These bike racks worked great, very sturdy, easy to install, easy to mount and secure the bikes on. I have a mountain bike and cruiser, both are heavier bikes with large diameter supports and fit perfectly in the upright clamp. I drove the bikes out to Burning Man - the roughest, bumpiest road into the desert I have ever been on and the bikes stayed securely in place.
We purchased the V-Rack because we wanted to be able to quickly transfer it between our motorhome and SUV, both of which have towing hitches. The V-Rack actually just clamps onto the exterior of the hitch stinger (2-inch), and locks into place, although it naturally takes a pretty substantial force to clamp it closed. The adjustable frame saddles with rubber strap tie-downs worked beautifully, and the bicycles exhibited no tendency to rock or jiggle while on the road, despite the light-weight appearance of the V-Rack. I rated the quality as "good" in part because the instructions are a little sketchy about opening the rack completely for installation, a technique I finally figured out myself. Also, if your vehicle has a 1.25 inch hitch stinger, you will need to buy the Advantage adapter, which expands the stinger from 1.25", to 2.0 ", around which the V-Rack then securely clamps. This rack has completely satisfied us and, just as we hoped, is transferred easily from one vehicle to another. It is definitely a "recommend" from us.
