Cyclists far and near are finding that you no longer need to have your iRiver E300 stored away in your backpack (or saddlebag) when out on a trek. With the Gomadic Handlebar Mounting system, you can always have constant visibility and easy access to your device at all times. With a custom designed mounting base that will easily attach to your bike handlebars (diameter range of 13-28mm) and a holder built to accommodate the dimensions of your iRiver E300, your device and your handlebars will quickly become one integrated unit. Do not ride a bike? No problem, as this holder also works great on ATVs, golf carts, snow mobile and even baby strollers!
