sorry if this is a dumb question but I have never hauled bikes in the back of my truck before. I live blocks from a nice bike trail but doing a charity ride and put the fork stem mounts in my truck. (Yakima Blockheads)

Question: Do I need to do anything with the back end of the bike? Will it dance around on me? I have a rubber bed mat in my truck but don't know anything about hauling them.


thanks!
