Japanese bike-sharing service turns a BMX bike into a DJ toolkit. The wheels become jog wheels, brakes do double duty as sound pads. Gyroscopic motion sensors on the bars feed the fader pad. Sounds are transmitted to the bike through an iPhone or iPod, to produce the sweetest set up ever to hit the ramps and roads. The set-up is available on COGOO, a bike sharing service in Tokyo, Japan, from around $35,000.”]
