Strange sound

[tilnissen]

Hello. My suito-t comes with a strange squeak/clicking sound when I have been running for about 30 minutes. It doesn't stop, but isn't as loud when it goes uphill.
If I stop pedaling, and instead step backwards a few times, the sound stops for about 2 minutes. But then come again... Do you have any idea what it could be, I have a video recording if you want to see
Regards Brian

Hi there!

Same situation here.

It appears suddenly and no matters how much time I have been pedalling.

I have checked through the "window" that magneto-wheel and magnets are OK and there is no friction between them.

Any idea about what items could make this annoying noise?

Thanks!
