If I may add to the messages - I have had the opportunity over the years to try multiple different racks from several different manufactures. More specifically, I had 3 different racks from Saris(2 hitch mounted, 1 spare mounted), 2 from Thule(both hitch mounted), 1 from Yakima(hitch mounted), 1 from SeaSucker(vacuum cup mounted to the roof), 1 from Kuat(hitch mounted) and 1 from 1UPUSA(hitch mounted).
Quite honestly I was most pleased with the Kuat NV, as it was hitch mounted, robustly built(but heavy), and included factory bike locking cables and a factory work stand. But it was heavy - both to remove and move around, and in the added weight to the rear. Pleased with it, until I tried the 1UP.
This past fall I acquired a single mount rack from 1UPUSA - because I needed something to fit a fat bike. While a tad higher on the price side, it is a truly remarkable piece of kit. All aluminum, very robust yet VERY lightweight, fit ANY bike from road to fat, and when not in use, can fold itself into a smaller footprint and can be carried with one hand. And as the name implies, its designed to hold just one bike, but it can be increased in size, almost indefinitely. I can not say anything negative about the rack or the company. Each one is hand made, in Wisconsin USA, and ships same day generally, in a very stout box.
As it is now, the 1UP will be fixture with permanency. I have sold my other MTB bikes and will be riding fat year-round. I might look at add a second bike holder as I may add another bike(and a rider to go with the bike).
