Moscow + crank vibration

[Milbs]

Had my 29er for 9 months - have only done maybe 700kms - lockdowns/weather etc - but have now started to see some issues.

Under load I am getting a vibration from the low centre of the bike - maybe the crank? Anyone else had this?

I also have issues with the PAS not behaving as it should - need to go through the gears to get it to kick in. I’ve been in touch with the dealer and they are sending me a new sensor to see if that fixes things.

I had it serviced this week (just mechanicals, not electrics) and the comment from the tech was that I had higher than expected pad wear, the brakes needed bleeding and I had loose spokes front and back. He also took a link from the chain as he thought it was too long for the setup.....

I had the exact same problem. I think I fixed it but changing the chain. I did that and noticed, on the stand, there seems to be less vibration. There is still some at the highest gears, but I also run my back tire with slime so that could be causing things to be slightly out of balance. I only took the bike out on the road for a short time since then, with winter in full force now, but in the quick ride I did things seemed much smoother. But - it was only a 5 minute ride, at most.

For what its worth, I had 1100mi/1800km on the bike and the chain was 1/16-1/8" stretched after measuring out 24 links. I know you have many fewer kms on yours, but it might be worth checking. The chain that comes with the bike doesn't seem that great.
