My rack is not built with the mesh like those shown. Mine has 4 angle iron channels that fit the bike tires.
A word of caution. I had bungee'd mine to the uprights and my wife was following behind. She flagged me down after one major bump and said that the biked had raised at least a foot off the rack. Make sure you strap them to the bottom of the rack as well as the uprights. Maybe common sense for most, but I messed up.
I do love having the rack!
