While this error is rare, it does happen infrequently and is not unheard of. There are multiple potential causes of this issue making it tricky to resolve in some cases. We will be here every step of the way to resolve this issue with you. 

Please try resetting your display by following the link below for your specific model. 

Please verify the wheel size/diameter setting in the display and take a picture.


If you have 2 ebikes with matching display connections and motor connections, the troubleshooting process can be expedited as noted below in section 2. It is still good to verify connections and wires are undamaged as noted in Section 1.


Section 1: Reset display, verify settings, check connections.

This issue may be as simple as resetting your display and verifying the settings.

If that does not resolve it, please trace the wire from your display, carefully disconnect it (should be green as shown in picture below with 5 pins), inspect it, take pictures of each end, then carefully re-align the arrows and connect it if no damage is found.

The next step would be to inspect inspect external and internal wires and connections.

10% - Display Settings Changed: Try resetting your display by clicking the link above for your model.

40% - Cable or Connection: A loose or disconnected cable is the most common cause of this issue. Please refer to the link above.

20% - Controller: The internal controller is not correctly transmitting the speed data to the display. Replacing the controller resolves the issue. 

15% - Display: The display is not reading or transmitting the data properly. Replacing the display will resolves the issue.

15% - Motor and motor cable: The sensors inside the internally geared motor are not correctly reading the speed because a magnet is out of place. Replacing the motor resolves the issue. Please check and report any damaged or bent pins on the 9 pin motor cable on your chain stay.



Section 2: Troubleshooting with 2 ebikes

Unfortunately there is no easy way to diagnose where the issue is coming from unless you have more than one bike in your possession. If you do have 2 bikes with matching connections as shown below (9 pin motor cable, green 5 pin higo display), this issue is easy to diagnose.


1 - Plug in the motor cable on the chainstay to the bike with the functioning speedometer, make sure the arrows are aligned before connecting the motor cable. Test if that resolves the issue.


2 - Plug in the functioning display to the bike with the non-working speedometer. Make sure green higo connectors are properly aligned and the 5 pins are not bent or damaged.Test to see if that resolves the issue.


Trying both the display and the motor would eliminate those potential options and leave you with only the controller as the source of the problem.
