Description

If the controller temperature becomes too high, it may lead to reduced efficiency or functional anomalies. Therefore, when the controller temperature is ≥ 100°C for 1.99 seconds continuously, this error will occur, and power assistance output will stop.

⚠️Triggers of Error Code

The following are possible causes of error code 80:

  • The controller overheated
  • Defective controller

1 Move the bike to a Well-ventilated Area

Turn off the e-bike.
Move the e-bike to a well-ventilated area with room temperature to let it recover to the proper system operating temperature for at least 10 minutes.

 
 

2 Go for a Test Ride

Turn on the e-bike. Adjust the support level to 3 and go for a brief ride on a flat road to verify the presence of system assistance power output. If it's not functioning or if the error persists, proceed to the next step.

 
 

3 Replace the Controller

Replace the [Controller] with a new spare, then reboot the e-bike to check if the error code still exists. If this doesn't fix the issue, proceed to the next step.

 
 

4 Reach out to the Service Team if you need additional support!

Contact Customer Care or the Hyena Service Center for further technical assistance.
