Solution:

The noise can be reduced by adjusting the chain guide/tensioner.
Please follow these steps:
  1. Locate the two screws securing the chain guide/tensioner bracket.
  2. Loosen both screws slightly. Do not remove them completely.
  3. Once the screws are loose, push the chain guide/tensioner part outward to create more clearance between the chain and the guide.
  4. While holding the part in the outward position, tighten both screws securely.
  5. Rotate the pedals/wheel and check the chain movement to make sure the chain is running smoothly and is no longer rubbing against the guide.
  6. If necessary, make a small additional adjustment until the chain runs quietly and freely.
This adjustment can help resolve chain noise caused by the chain rubbing against the guide/tensioner.
