With the fatbike tire modification & use for all 4 seasons, we can easily transfer the rack between both car receiver hitches, on the back of our travel trailer for any of our bikes on the roughest BLM roads (using a modified rigid hitch extension-helps handle the bucking) (without wheel removal or fear of scraping off the seriously spendy equipment at home, at a parking garage or lower hanging branches)….Spendy but provides peace of mind. Didn’t realize you could add 3 units to the base for 4 bikes (? thought it was a total of 3).
