Looks neat, but it probably will add another 100 pounds + to your tongue weight. The rack weighs approximately 50 pounds (accordoing to the website). Bikes weight (at least) 30 pounds each, more if they are a box store bike (35-40 pounds).
Bottom line is all that weight is put pretty much on the tongue. So, if you are tongue weight challenged, you may want to consider a roof rack on your vehicle instead.
