Just a heads up not forget the Rear Braking Assist if you are using a hitch mount bike rack. I used mine for the first time a few weeks ago with 2 bikes attached and started baking out of my driveway. The Rear Braking Assist slammed on the brakes and I thought I hit a brick wall! Also forgot about it later in the day and the same thing happened again. If nothing else at least I know it works.
