If you encounter error codes 22 or 30, it indicates that your bike's throttle requires calibration. We're thrilled to share that Favorite Bike introduces new features every two months, and our dedicated technicians continually update your bike controller with the latest firmware. However, we've observed that some models might not have completed the throttle recalibration after a firmware update. If you're facing such an issue, please reach out to our customer service team. We'll conduct a remote system update, or alternatively, your dealer can assist with the update process.
