Sometimes a better mousetrap come along, with bike transportation, this happens every year or so. Everyone trying to make it easier, quicker and the ability to handle multiple bikes. I love roof mounted bike racks, they have their downfalls, mostly, garages. UpSide seems to have something pretty good. If you already have a factory roof rack or aftermarket, you do all the work on the ground, lift it up and twist to secure it to your car.
Simple!
