Error code 11H on the P850C eBike display indicates a motor over-temperature issue. To resolve this:

1. Stop using the eBike and allow the motor to cool down.
2. Check for any obstructions or excessive load that may be causing overheating.
3. Ensure proper ventilation around the motor.
4. Restart the eBike after it has cooled.
5. If the issue persists, inspect the motor connections or consult a technician.

If the problem continues, professional service may be required.
