Wired and Gizmodo are showing an interesting iPhone application and accessory: the LiveRider. Wired describes the hardware: "It comprises a frame-mounted sensor which cable-ties onto the chainstay (the bottom tube) and senses speed and cadence (cranks per minute) via magnets attached to the wheel and crank. This beams its info via 2.4 GHz RF to a dongle plugged in to the iPhone. The iPhone itself sits snug in a shock-absorbing handlebar-mount."
