The Peloton bike is factory-calibrated to minimise variations in resistance between Bikes. Outside of very specific circumstances that the Peloton Support team can diagnose, there is no need to calibrate again. We often find that when members attempt to calibrate themselves, the output can actually become less accurate.
If you are experiencing any issues with your Bike, please contact our Member Support team by calling 03221-1001778 (Option 2) or emailing support@onepeloton.de.
