EggRider display speed shows --.- km/hLink

EggRider display showing speed as --.-km/h or error FF (EFF) can be caused by the following reasons:

  1. Protocol is not correctly setup
  2. Communication port issue
  3. Controller is not compatible
  4. Bafang error 30H

Protocol is not correctly setupLink

EggRider display supports multiple bike communication protocols, each controller brand has two possible options, for example Bafang and Bafang Rx/Tx Swap, but only one of them will work with your bike.

Most of the time the protocol is auto-detected when display is reset to factory settings. To reset, when display is OFF press M+Power buttons until display turns ON.
For more combinations, see EggRider v2 buttons or EggRider c1 buttons

Once you have identified the correct protocol for your bike, do not change it when referencing settings examples from other sources.

After reset, if speed is not shown as 0.0 km/h, please follow the steps below:

  1. Connect to display with mobile app
  2. Go to Display settings page, press Read, change Protocol type to your controller's brand name (example: Bafang) and press Write.
  3. Restart the display
  4. Check if speed shows 0.0km/h
  5. If speed still shows --.-km/h, repeat from step 1 and change protocol to the Rx/Tx swap version. (example: Bafang Rx/Tx Swap)

Do not confuse controller brand with motor brand. For EggRider, it is important to identify the controller.

If none of the above resolves the issue, the cause is most likely reason 2 or 3. In this case, please Contact us via email.

Communication port issueLink

This is usually the case if EggRider was previously showing the speed correctly. The issue can be either on EggRider display or on the controller side.

How to identify the source of the issue:

  • Connect another compatible display to your bike or controller. If speed is displayed correctly, the issue lies with the EggRider display. In this case please Contact us via email.
  • Connect the EggRider to another bike or controller. If it works correctly, the issue is on the controller side.

Controller is not compatibleLink

If the issue is not resolved by following the above steps then it is most likely a software incompatibility, please Contact us via email.

Bafang error 30HLink

Some users have reported encountering error FF known on Bafang as Error 30H with specific Bafang controllers, particularly when trying to change controller settings with cable or EggRider app. This error might indicate that the controller has restricted the ability to modify settings.

A common indicator is the error occurring while adjusting Bafang controller settings.

Potential solutionLink

Many users have resolved this issue by reinstalling the firmware on the controller. While we don't have direct experience with this process, the following resources may be useful:

It appears that some versions of Bafang controller firmware may limit the number of times settings can be changed (e.g., up to 5 times), or in some cases, may not allow changes at all. Additionally, the error can occur when incompatible settings are written to the controller.

Based on customer feedback, using the above resources has successfully resolved the 30H error. However, we cannot confirm whether the issue will recur.

Preventing error 30H from recurringLink

Once the 30H error has been resolved, you can help prevent it from recurring by using the EggRider display without modifying the Bafang controller settings. Follow these steps to do so:

  1. Open the EggRider App.
  2. Navigate to the Display settings page.
  3. Select Bafang switch mode.
  4. Choose Only live data.

This setting ensures that the EggRider display shows real-time data without changing any Bafang controller settings, minimizing the chances of encountering error 30H again.
