I chose the Easyfold XT2, based on two main criteria:
1. Ability to use with both 1.25 and 2" receivers (out of the box). I had to have a 1.25" hitch installed on my current car, but plan to go to a 2" hitch when I get a new car. It will be nice to be able to use the same rack.
2. Relatively compact folding/storage. When folded, the XT2 is really quite compact and even includes wheels (albeit, it is easier to lift/carry then to try to wheel it around). It stows away nicely when off the car in garage.
We purchased 2 Specialized Vado 4.0 bikes, and each weighs ~55 lbs. So, I had to switch from my roof mount Thule to a hitch rack. After looking at several brands/models/reviews, I settled on the Easyfold XT2. All the best platform hitch racks are expensive, but this model is near the top at $900.
Overall, I'm happy, but the attachment bars (1 short/1 long) are less than easy to use, and if you are not careful, can easily scratch 1/both bikes. On the way home from the dealer, my brand new Vado had the paint rubbed off where the attachment bar was hitting the downtube...Now I check very closely after placing both bikes on the rack.
Finally, I am quite happy with my purchase from Oregon-eBikes. They shipped it quickly, it was competitively priced, and of course, I did not have to pay sales tax (California).
