I bought the XPORT Slipstream 4 from Performance Bike a little while ago and finally had an opportunity to use it.
I first had to install the hitch to my Hyundai Elantra- the instructions said it was fairly easy and would take 30 minutes. It was a bit of a pain, but that could have been because I was doing it solo and the hitch is pretty heavy when you're laying under a car.
The hitch rack was very easy to put together and install on the car- very sturdy as well! I had my GF Cobia and my wife's hybrid on it for a 1.5 hour trip to some trails. This rack is very affordable and effective! I got it for about $120. The straps were hard to first attach them to the rack; however, you only have to put them on the rack once. The straps weren't too hard to work with when the rack was on the hitch- much more leverage.
Once I arrived to my destination, I checked the rack and noticed it was loose where it attaches to the hitch. The bolt loosened a bit. It's a threaded bolt with a locking washer and I guess it worked itself out a bit- the pin is still attached so there was no worry of the hitch going for a ride on the highway, but just something to watch out for- good to check it once in a while. I am also keeping a rachet and 19mm socket in my trunk since you need that to attach/detach rack from hitch.
I am very pleased with this rack- especially since it's so sturdy and inexpensive. let me know if you have any questions.
