Cranks in the motor when pedalling

[Surfer_D]

Hi Guys,

I hope english is fine as well. I have a new bike xduro nduro 8 flyon and noticed that the motor cranks (same noise as chain makes when incorrectly shifting down under power) when I start to pedal. Just when I start, after one revolution then it's fine.

Example: I ride down the hill and while going down I shift into the small gears - quick three turns to get the chain on the small gear. Then when the hill goes up I press hard on the pedals to quickly get fast - here I get a metal crank/sound as if the chain wasn't correctly positions. It happens in the motor not in the gears/derailleur.

Service couldn't replicate it though it happens all the time. Anyone else has this issue?

Hi Surfer_D,
maybe there is a little pebble in the housing?

Hi, maybe you should adjust the screw-B (Shimano XT), I think I had the same problem once
