7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Bike feels unstable or wobbles. | Loose stabilizer bolts or uneven surface. | Ensure all stabilizer bolts are tightened. Adjust the leveling feet on the stabilizers to compensate for uneven floors. |

| Difficulty connecting via Bluetooth. | Attempting to connect through general device Bluetooth settings; incompatible app. | Ensure you are connecting directly through a compatible cycling app (e.g., Kinomap, Zwift). The bike's Bluetooth is not typically discoverable through your phone's general Bluetooth settings. |
