Troubleshooting – Screen Casting Not Working – Showing “Unauthorized”

Step 1 – Check the Screen Cable Connection

First, check the wiring behind the screen:

• Make sure the cable at the back of the screen is firmly connected.

• Ensure the connector is fully inserted and not loose.

  

A loose screen cable may prevent the device from being recognized correctly.

Step 2 – Confirm Data and Flywheel Light Status

Check whether the data on the screen (such as speed or cadence) can change normally while pedaling.

Also check the lights above the flywheel:

• Solid blue light

• Flashing red and green lights

  

These indicate that the bike is working normally.

If:

• The screen data changes normally, and

• The flywheel shows a solid blue light with flashing red/green lights,

Then you only need to authorize the bike in the app:

1. Log in to your account in the YESOUL Fitness app.

2. Tap the “+” icon on the app homepage to add a device, or select any course.

3. Follow the prompts on your phone to complete the connection.

After this, your bike screen should display “Authorized.”

Step 3 – If Screen Data Does NOT Change

If the data on the screen does not change and there is no flashing red light above the flywheel, please check the internal connections:

• Inspect the terminal under the screen bracket

• Check the connector inside the head tube and frame

   

   

Make sure:

• All terminals are fully plugged in

• No cables are damaged or broken

If everything looks normal:

• Unplug the terminal connector

• Check whether any pins inside are bent

  

Note: If a pin is bent, gently straighten it.
          If the terminal or cable is damaged, please contact customer support for replacement.

Step 4 – Connect Bluetooth in the App

Open the YESOUL app and connect to your bike via Bluetooth according to the on-screen instructions.

Step 5 – If Bluetooth Cannot Be Found

If your phone cannot find or connect to the bike’s Bluetooth, please refer to the following article:

• Troubleshooting – Bike Cannot Connect via Bluetooth

Follow the steps in that guide to continue troubleshooting.
