The Fitibit One ($100) is Fitbit’s latest 24/7 tracking device.

During the day, it clips to your belt or slips in your pocket to track your steps, the stairs you’ve climbed, and the overall calories you’ve burned doing so.

At night, the One slips into an armband, where it measures your sleep cycle and will vibrate in the morning to wake you up, silently.

I want a device like this that also tracks biking.  When will this happen.
