The prototype in the video below demonstrates the system in action, relaying speed, heartrate, power, cadence and even exterior temperature to the 2.2-inch LCD screen. The system supports ANT+ wireless, so it can source data from an optional crank sensor to get an exact measure of pedal force, and a microSD slot and microUSB port allows you to transfer data from your last ride. All that, plus there's the GPS functionality, which would play awfully nice with Google's MyTracks app. There's no word on a release date or pricing, but we'd suspect Pioneer would want this to hit the market just in time for the spring/summer cycling season.
