PoorBehavior, your link is broken. And none of the performance racks are as substantial as the sportswork racks. With the extender, there is no problem mounting the rack on a hitch. If you have a bent or semi-bent like the Giant Revive, you'll need to get the mod series and one of the recumbent trays. Recommended for 2" hitches, but works fine with 1 1/4". Just make sure you have a good quality hitch.

About the racks, i.e. the mod series where you can use 1 tray or 2 trays according to how many bikes you want to carry.

-- extremely easy load and unload
-- if I had a flatter driveway approach, I would just leave the rack on most the time. Clearance with driveways and a rack on a sports car means you enter/exit at an angle.
-- there is a small about of movement at speed, but my guess is that is there with any rack. Basically the rack is supportedby a slightly larger than one inch square steel tube. Very solid but it's not one with the vehicle.
-- the tension loaded arms are a snap to lift and load your bike. Once the arm is dropped the bike stays put.
-- with 2 bikes, I like to put a bungee cord connecting them on the top so I see less bike movement in the rear view mirror.

More questions? Hope this helps.
