Mounted on handlebars and roll cages
The LiquidAider button and guard mount next to your grip. From this position you can change operation from "demand mode" whereby water squirts as long as you hold the thumb button. Or go into one of the 3 "burst modes". In burst mode, a quick press of the thumb button will result in a 2, 3, or 4 second burst of water.
At about 1 liter per minute, 4 seconds is a mouth full!
The button can be mounted to roll cages. Here are a few shots showing a simple method. Probably best to use a hose clamp, not a zip-tie as shown. These pictures of the roll cage mount show a 3D printed prototype, not the production button.
