I don't know what todo anymore.
The chain is sliding from the front chain ring when I'm not actively pedaling. When I'm actively pedal, it does not slide off.
The chain is not a week old, and it's the same as before.(for sure) Thought it was the front chain ring and changed it but it seems to be the same as before.
One thing to consider is for sure to give the bike a proper clean as its dirty as hell.
But I don't think this will solve the problem, sadly.
My gf rides it every day for like 2 hours thought tough terrain.
It got 6900 km in like 2,5 years.
Every 3000 km I have to change some major parts it seems like.
But this time the chain keeps sliping even after the change.
The bike is a Raymon HardRay E-Nine 6.0 - 500 Wh - 2021 - 29 inch/zoll.
Any help is appreciated. Thanks
