For those of us not rocking monster dually pickups with space to hang 57 bikes over the tailgate, hitch-mounted tray racks are the most pro way to go. The bikes are locked down on the tires, meaning that frames aren't getting banged together, and hiding the bikes behind the car means your gas mileage won't get knocked down so much that the Koch Brothers are gleefully checking their gas station stocks.
They're also expensive - Yakima's HoldUp we're about to review here cost $450, which is a pretty penny for hosting two bicycles - so getting the right one is pretty important. Unless, of course, you're one of those dentists I made fun of in my last gear review.
What's cool about this particular offering from Yakima is how ideal is it for those of us putzing around in more petite vehicles. With a streamlined, compact design that makes it as aerodynamic as possible, both when in use and when folded up, and good ground clearance while tucking the bikes in as closely to the profile of your car as possible, your gas mileage stays intact no matter how long your road trip
