3X3 electric shifting not working

Troubleshooting: What to do if your 3x3 gear hub stops shifting

If your 3x3 electronic gear hub system suddenly stops working, follow these steps to quickly identify and resolve the issue:

1. Check the Shifter

Press the shift buttons on the handlebar and observe the indicator light at the handlebar end.

If it flashes green: The shifter is working correctly, powered, and transmitting a signal.
If there is no light: Replace the battery in the shifter.

2. Connect to the 3x3 App

Open the official 3x3 app on your smartphone and attempt to connect to your bike. (https://service.3x3.bike)

A) The app cannot find or connect to the system:

The shift unit is not receiving power. In most cases, this is caused by a damaged or faulty USB-C connector/cable between the powerbank and the system. Replacing the cable usually resolves this issue.
B) The app connects successfully:

Check the main dashboard in the app. The system will automatically display the specific error code or status message to help pinpoint the issue.
