The iPod Speaker case can be clamped onto the bike frame with your iPod docked inside. The remote control is mounted on the handlebars. As the case is plastic, the speakers are water-resistant.
Implications - There are so many varieties of iPod speakers on the market; what I particularly like about this one is that it lets you go mobile. Now you can blast your tunes just like your car-driving friends. The water-resistant feature was a nice touch for these speakers because rain certainly becomes a factor on a bike.
