My bike is making a weird squelching sound from the back wheel. Any idea what it might be? I made a video of the sound, it's at this link: https://drive.google.com/file/d/1zt_DAa2avX9bhJ4E-moLFJ69TSYnb2uC/view?usp=sharing
Summarising comments:
- the noise is in the rear wheel
- frequency is linked to wheel/road speed and not chain speed because noise continues when coasting,
- noise does not change when the rear coaster brake is applied
- noise only appears when bike is loaded, not walked
- there is nothing rubbing on the tyre
