  • How Can I Calibrate Exercise Bike's Speed?

    In order to make Jacfit sensor fit your exercise bike and get more accurate data, you have to calibrate the speed.

    Based on your sensor installation, there are three different ways to calibrate the speed.

    For manual mode, riding the exercise bike, when the bike's speedometer reached around 12.5 mph, pressing the calibrate button.

    Note: Only the speed of the exercise bike needs to be calibrated.

    For bikes, we have different algorithm.
