Error code on RadUI display
Error 31 indicates a failure during the power on sequence, often caused by holding down the power button for more than six seconds, or if the power button is stuck. To fix this error:
- When powering on the ebike, release the power button once the display and remote light up. There is no need to hold the power button any longer than that.
- If the error persists, check that the power button on the remote is not stuck in place. If it appears to be stuck, power down the ebike and use a small tool to dislodge the button.
- If you continue getting the error 31 code, take a picture of the remote and display and contact Rad Power Bikes customer support.
