Hm, i was always under the impression that most bike systems use a simple magnet and a reed switch (no need for hall effect sensor) for both cadence and speed measurements. So any sensor from a regular bike computer can be directly attached to the mic line of FR. They do, and they eventually

Umh, you may take the freerunner attached to your leg and use accelerometers? Im thinking about using the neo freerunner while Im running/jogging. It could count my steps (using the accelerometer data), measure the exact distance, and plot the average speed across the distance. It could have
