It's not, no - it has a rinky-dink little computer with a simple 7-segment LCD, which is connected to whatever in the bike is measuring rotations via a 3.5mm jack. I did experiment with seeing if I could read a signal from it via a mic input so I could hack together a more advanced display but didn't have any luck.
I've just had a look for ways to adapt it though, and found BitGym [0] which doesn't require a connection to the bike at all - you just place it on the handlebars and it measures your cadence with the front-facing camera somehow. That would be a neat feature for Startona. Maybe you could even measure it via the accelerometer? FFT the lateral motion of the device to find the frequency of movement? Maybe it wouldn't be strong enough but it would be an interesting experiment
