The racks I'm seeing weigh about 30-45lbs, and I figure my bike can't weigh more than 25lbs, maybe more, and my fiancee has the same bike just women's, and our kids bikes are tiny, so like 10lbs each...i guess bikes aren't really a concern...but luggage. I would think a few suitcases might over do it...
thanks for the link but the poster obviously doesn't know what he's selling. that looks like a 1 1/4" receiver which from my research means its a class I, because all class II and III's come with a 2" receiver.
