Troubleshooting

If your bike cannot connect to Bluetooth, the most common reasons are:

• The bike control board is not responding

• Bluetooth is not enabled on your phone

• The bike is already connected to another device

   

  How to Solve

  Step 1 – Check the Adapter and Cables

• Ensure the bike adapter is properly plugged into a power outlet.

• Check the cables behind the screen and make sure they are connected as shown in the diagram.

  

  

• ⚠️ Note: Loose or incorrectly connected cables can cause issues with the screen or Bluetooth.

  Step 3 – Your Phone Bluetooth Settings

• If the flywheel lights are normal, follow these steps on your phone:

    Check Phone Bluetooth

• Turn on Bluetooth on your phone.
• Make sure location permission is enabled (required for Android).
• Open the YESOUL app and search for your bike again.

• ⚠️ Important: Do NOT connect the bike directly through phone settings—only connect via the app.

    Check Phone Bluetooth

• The bike can only connect to one device at a time.
• Reset the bike according to the user manual.

• If the green light on the bike is solid (not blinking), it indicates that the Bluetooth is already connected to another device. Please disconnect that device first before attempting to pair.
