Why not just use the bed for bikes?
I used to put my bike or bikes in the bed while using a tailgate pad. The issue I ran into, was that they naturally took up most of the bed space. Not to mention that if I wanted to run an errand after a ride, I'd have to drop the bikes off if I needed to use the bed.
I also needed the ability to use my bed while bringing my bikes with when going on camping trips. Basically keeping the bed free and clear while having the ability to have a bike with me was one of the main goals for developing the SideRide
