Has anyone had any experience with the rack sold through Tesla? It doesn't make a whole lot of sense that they would sell a rack that can supposedly hold up to 4 bikes but if you subtract the weight of their hitch (which comes in at 40lbs) your only left with a total of 80lbs for the bikes. However, the specs for the Tesla rack clearly state; "The Model X/Y hitch is designed to support loading of up to 120 lbs" (Tongue and Towing capacity is discussed in more detail on this thread). Wondering now if it's worth it for me as I can't very well leave one of the bikes at home if I go on a family trip? Worst case scenarios is I guess I could put (2) bikes on the rack and (1) bike in the trunk (kind of defeats the purpose). Also, although I'm not planning on towing a trailer of any size, it's probably not practical or advisable for a SR RWD.
I bought the Yakima ridgeback 4 which is the same as what Tesla offers. I loaded 4 bikes totaling 120 and the weight of the hitch is 40 bringing it to 160 on a round trip to San Diego this past weekend. Worked fine!
