Yeah this isnt anything big or fancy but if a feller wants to go for a short ride and not take a bag or tank bag then this works. I have never lost a bottle yet and bungee cords are great to have on a bike anyway. Its easy and convient just to throw a bottle on the bike and go. It works very well with 16.9-20oz bottles. Off/On in seconds without undoing your bungee, just move the cord over and pull out your bottle. Anyway i thought i would share this since i find myself doing it all the time. And you can still put a bag over it on the rack and have the extra bottle..
