I'm very pleased with this bike rack so far. I have a fat tire bike (27.5'' wheels, 4.5'' tires) and this rack is one of the few that does accommodate my bike. It does come with 1 strap extender + 1 velcro strap for front wheel in box. Wasn't super clear in description so I bought an extra set to be sure, can't hurt to have a spare (or extra set for 2nd fatbike).
The only thing is the ratchet arm won't extend enough to go over the wheel from its lower position (for my specific wheel/tire combo). It does work if I leave it up so I can slide the bike sideways under the arm and them push it down snug. No big deal.
It does need assembly, takes about 20 minutes, all tools are provided. It installs in 2 minutes on you hitch, again no extra tools required (#2 reason I bought this one, I can get it on/off super fast if needed).
I managed to open my tailgate fully once I dropped the front wheel cradles to their lowest position (no bikes loaded of course). Otherwise the tilted position helps get a little more clearance but won't allow to open fully with bikes on.
Feels super sturdy, has not come loose since I installed it a few weeks ago. Bikes don't seem to move a lot when travelling, seems pretty secure. I like the 1-key lock system (hitch pin + 1 cable on each bike). Blackout design looks great with my truck, doesn't stick out much from the number in its folded position. Still can see the licence plate and backup camera isn't blocked.
Yes it's expensive but so far it checks all the boxes for me so I would recommend it.
