I've had this bike rack for 5 years. I've had 4 bikes on it many times...no problem. The one I have does come with a lock (for locking it in the hitch - maybe the newer ones don't?). I leave the rack on my 4Runner from spring to fall and it's weathered all sorts of storms. It doesn't rattle (with or without bikes on it). The bikes are very secure while on it. I can't think of anything Yakima has missed with this.
