Anyone facing the same issue .

- Happen intermittence , usually after 1 hour into the ride and during big climb.
- Sound so loud from the motor, and crank not smooth
- Once stop pedaling around 20 minutes, no more issue
- Motor mileage around 400KM
- No issue detect from the app

Sound exactly like below :

I did bring to the shop and check. No issue found :


is it due to frame protector which cover the motor causing the temperature to rise . ?
