designer's own words:Velosonix is a music player specialized for bicycle riders. My main concern with designing this product was EZ-installation, EZ-interface, and Aerodynamics. Instead of a bracket that requires tools, I chose rubber o-rings for easy mounting and dismounting on handle bars. Also the joystick makes it easy to change songs or volume for riders who wear gloves. For aerodynamics, horn shaped speakers pointing forward will reduce the air resistance.
