Pin Box Bike Rack Source

I am one of the ones that made my own mount. I looked everywhere for over a year trying to find one. The only commercially made one was the one you see in previous posts. Arvika. I made my mount, then bought a commercially made rack for mine to fit in. Mine is a 3 bike rack, the Arvika is up to a 4 bike rack. That is the reason I made my own. I bought the rack I wanted and used the dimensions to make my mount. Any metal fabricating shop should be able to help you out. The Arvika rack is expensive in my opinion, however I have seen two in person and they are nice. I have less than $35 in my mount, and $145 in my rack.
