Half of the reason, and probably more than half of the usage I will get from my 2" receiver will be for my bike rack. When I look at my Wrangler, probably have towed a trailer a dozen times or so in 6 years, maybe a little more. Primary uses for the 2" receiver were the bike rack and the hitch hauler. I may actually have a hitch hauler to sell now that I have a pickup truck. I don't see a big need for it anymore.
Only downside to the bike rack is that I have to remove it in order to drop the tailgate and get the ice chest out of the bed of the truck. I have seen some really nice bike racks that actually swing out of the way to the side so you can drop a tailgate or raise a liftgate. If I was going to buy a new one, I would spend the extra bucks for that functionality. Mine will pivot down, but I am not sure there is enough clearance to allow the tailgate to be dropped in the mode.
