Allen Deluxe 4-Bike Hitch Mount Rack review - Hands on Kitchen I just received my bike rack from Amazon, was iffy on it due to price but the reviews on amazon were mostly 4 and 5 stars. The unit came very well packed, 3 bolts 3 screws, and 3 different pieces of metal. Took about 5 minutes to put together. Once mounted into my 2 inch trailer hitch and the 19mm nut tightened down that holds it to the hitch, everything snugged up nicely. Very solid. Haven't had it loaded up with 4 bikes but I see no reason as to why it wouldn't work flawlessly fully loaded up. Storing the rack is also simple, I have it hanging on my fast track system from rubber made. Once I buy another fast track arm, I will hand the rack directly on the wall reducing the amount it sticks out into the garage. For $89 I'm very impressed with it.
