That looks way sketchy 442. I guess it would depend on the value of your bikes your hauling though. I have been using a hitch mount 4-bike Sportsworks rack for 5+ years now and love it. SportsWorks consumer line was bought out by Thule about a year ago. I checked out the latest at my LBS and its even sweeter(more adjustable now)!

All I can say is spend the extra money and get a real rack....When your hauling over 20K+ in bikes its nice to be able to watch the road infront of you. instead of wondering if you have dropped a bike
