Highland SportWing Hitch Rack
I have been extremely pleased with this rack. It carries bikes by their wheels, and secures the frame to the "wings" using long Velcro straps. I bought a Ford Transit Connect for its high roofline and tall doors to carry recumbents, but I find that I can assemble and mount this rack faster than I can fold the seats down inside the Transit.

eTrailer was great to work with, and answered all my nerd tech questions before I bought the rack. I carried a Quest 1.0 and a Vision R40 all the way to Orlando and back without any issues with the bikes moving around or making noise, and the carrying straps never loosened or gave me a bit of worry. The bikes are held high enough where crossing road grades are not a concern, but their not way up in the wind and can bee seen-over when backing up. The vastly different frames of the Quest and the Vision were accommodated equally well.
Me Likey.
