Feedback Sports Rakk XL is a good one.
I have one that I think might be an older version and it held my 2.8 27.5+ bike very well. But, I admit it doesn’t do a good job with my 2.4 29er. It can also slide on the floor which can be a bit annoying. I have moved on and built a rack with wood similar to what rideit posted. If you like DIY, it’s a great way to go as you can make perfect for your tires and number of bikes.Feedback Sports Rakk XL reviews on REI website are very negative for this product.
