Code Settings
The display always shows a full battery status.
Select “Reset to defaults” in the settings menu and do a factory reset to see if the issue has been resolved. Reach out to customer service if not.
After the reset, I only see the speed and distances in kilometers. How can I switch back to mph?
Select “Toggle Unit” in the settings menu, and change “Metric” to “Imperial”.
How do I change the pedal assist level from 0 to 5?
In the "Advanced Setting” menu, under “Assist Levels”, you can configure the amount of pedal assistance you would like.
Error code 22: Throttle defect
Connect the cables of the throttle. Locate the throttle cable with the orange plug, disconnect then reconnect it to restart the throttle. If it still does not work, the choke must be replaced. Please send us relevant videos and your order number to support@birchhunters.com, we will provide you with assistance.
Error code 24: Engine reverb defect
Plug the motor cable back in. Locate the motor cable near the hub motor, unplug then plug it in again to restart the motor. If the error code is still shown on the display, send an email to us with relevant videos, the motor serial number, your order number and motor connector, and we will help replace your motor.
Errorcode 25: Bremsendefekt oder Bremse beim Start betätigt
Disconnect the brake lever cables one by one to check whether the fault is caused by the left or right brake lever. Try readjusting the bolts and see if that solves the problem. If you still see error code 25, provide us with relevant video and your order number at support@birchhunters.com, we will replace the brake levers for you.
Error code 30: Abnormal communication
You must disconnect all 7 plugs (2 brake levers, throttle, front light, rear light, sensor, motor cable). The display should then show error code 24. If code 30 is still displayed after disconnecting all plugs, there is a high probability that the problem is with the controller. If code 24 is shown on the display after disconnecting all plugs, connect the motor cable first. If 30 is displayed, the problem is with the motor. If there are no error codes after connecting the engine, connect the other connectors in sequence until code 30 is displayed. This means that code 30 is caused by that connection and this part must be replaced. You can then send us relevant videos and your order number at support@birchhunters.com.
