The first on-board computer for cyclists, New Potato's LiveRider connects your bike to your iPhone or iPod Touch — using a single dual-mode sensor to measure both bike speed and pedal cadence, transmitting the information to your attached device. After you've downloaded the LiveRider app, iPhones with GPS capability provide real-time location and tracking, while accelerometer features record inclination. Data can be reviewed on your iPhone or exported via email. The Chase Rider function allows you to compete against your personal best.
