I have a hitch mounted bike rack that supports two bikes in wheel trays. The cover was advertised to work for two bikes but did not. The zipper would not fully close so I had to tie the ends together with string as close as I could get it. The attached straps would not reach all the way around to the other ends so I used bungee cords to secure the cover for travel. When I reached our destination the cover had ripped through from the brake levers and other places. This cover might work with a rack where the bikes hang on the crossbars because the standup version uses extra space that was not accounted for in the design? I will use it one more time on the trip home and then trow it away. Not a great value for two uses.
