I finally located the perfect product that allows me to carry my water bottle on my handlebars. The Forte Water Bottle Cage Bracket. A really quality product that was easy to install and fits really secure.

My wife's bike frame doesn't have any mounts for a water bottle so this thread interested me. I found a top cap cage mount from King Cage that I think I'm going to buy for her as a stocking stuffer. See it here, second product down, on the right side column: http://www.kingcage.com/products-waterbottle-cages.html. I think this would be a little less distracting and possibly a bit safer, with the bottle held in a more horizontal position.
