Radon Relate 9.0 625CX Problem

Hi guys,

I received a Radon Relate 9.0 from my workplace as a gift a few days ago. The bike has already done over 9000 km.

The chain has been oiled, but today while riding I kept noticing these noises the whole time.

It mostly happens in higher gears, and I’ve noticed that the noise becomes significantly quieter when I turn off the motor.

In any case, the noise occurs when I’m pedaling.

Do you have any idea what it could be and maybe how much it would cost to fix?

Thanks!
