These are now on my peddle powered two wheeler. The one on the left is a regular handlebar mounted bottle cage (search that on ebay, about $4 or $5 with shipping included). The one in the center is a "bar hopper" cup holder. It's tapered to allow coffee cups to be mounted. On the left fluid reservoir is a $.99 cup holder designed to hang on teh inside of a car door that you can pick up at most gas stations or car washes. You can mount this on a bike by drilling a hole and using a p clamp.
