Troubleshooting: No Green Light Above the Flywheel (Normal Status: Solid Blue Light & Flashing Red/Green Lights)

Step 1. Confirm Your Bike Model

1. External Battery Models，Such as the S1

   • Replace the battery and ensure it is fully charged.

2. Non-External Battery Models

   • The green light is the Bluetooth indicator.

   • Only when the green light is steady on is Bluetooth properly connected.

Step 2. Check Mainboard Power

• Verify the mainboard is powered and check the power indicator light (blue).

Scenarios:

1. Blue light ON, green light OFF → Device is powered, but the mainboard may be malfunctioning. Contact customer service for a mainboard replacement.

2. Blue light OFF → Check the following components:

   1. Is the power outlet working?

   2. Is the power adapter functioning (check if its indicator light is on)?

   3. Is the mainboard power cable and connector securely connected, with no looseness?

      

Step 3. Check App Pairing

1. Pedal the bike to wake up the mainboard.

2. Open the YESOULfiteness app and follow the bike connection instructions to pair with the mainboard.
