The noise you have is exactly the same as I had, I removed the wheel, took the higher 10 gears of cassette off, took off the freewheel off to remove the outer axle, where there is a spacer with a washer in each side(The washers are different thicknesses apparently, so put them back in the same places) I added a photo of them below.
A small amount of grease in the mating surfaces of these, Popped it all back together, added a smear of grease around the thru-axle and the noise has disappeared.

It’s not hard but not easy......
I followed a link on the e13 website. I’ll try and find the link for you, but I’m just a bit busy at the mo.
Thanks! I will wait, or see if i can find that one myself. That sound is killing all the fun in a yt
I did get most of the annyoing sound away.
Now my bike seems to creak when i apply alot or pressure uphill. Lets say i put on boost and 2nd gear.
Sounds like the creaking comes from the rear of the bike. Atleast its not my pedals or crankarms...
Any clues?

Hi mate I had exactly the same fault as u.
I made a shim an put it in after the rubber seal on the drive side. There is not enough clearance or the bearings have moved through/in the frame causing the problem. I have not yet spoke to yt
Was that replay ment to me fatbap?

Weak it was meant for Elvis. But anybody it will help
Hi there I had the same problem it turned out to be my e thirteen rear wheel hub which I got replaced under warranty hope this helps the only reason I found out was to swap the wheel out from my mates decoyHey folks. I need your help/expirience please. I can't figure out, where those anoying, cracking noise is coming from (i can also feel it a bit through the pedals). I own the bike for about 5 weeks now and have 900 km on it. It starts 2 weeks ago on a trip in the swiss alps. I uploaded two video files, where you can hear it. The noise comes mostly , but not allways, when i'm riding uphill (very rarely in flat terrain). I checked every bolt and screw and tightened with right torque. The chain still looks (measured with a chain gauge) good enough. Maybe it's nevertheless the chain!? In the worst case it could be the Shimano Motor or the CF rear frame!? It's my first e-bike, but not my first CF bike. I never had similar noises on any bike.
Any ideas what else i missed to check?
After paddeling backwards, the noise sometimes is gone

The noise is still there after turning the engine off

Does any of you guys have the same sound coming from the motor even when turned off?

Hey Fatbap, thx for your reply. Can you tell me what measure your shim has? If you speak to YT, it also would be very interesting, what statement they have to this failure.

Hello Peter,
thank you for your feedback!
It can sometimes be necessary to use those little washers/shims, to adjust to tolerances in the frame. We would have done the same in our workshop, to solve the issue.
As all frames are handmade, this can always be necessary.
It's good to hear that you managed to resolve the issue by yourself, already.
As everything is running smoothly now, we suggest leaving everything as it is.
There is no need to send the bike back to us.
So the verdict is that if this happens to u, u will either have to send the bike back for them to add a shim or do it urself. I will be replying asking them is it possible to make the shim available so I others have this issue it can be sent to them rather than sending the bike back

Another update I have asked yt about my warranty as I have repaired the bike my self an also if the shims are available this is their reply

Hello Peter,
you don't have to worry about the warranty. This will not affect it.
We do have those washers in our workshop. Normally this is not something our customers do themselves, so it is sufficient to have them in our workshop.
But they would be available, if necessary.

Good on you for solving the issue .. YT should at least send you some SWAG for your work 
Any chance is sharing your "shim specs" … I can easily get some made (hope to never need them)

Yeah it’s a relief for me that I don’t have to send the bike back. Would be good to get something off them but did not think I would lol. I’ll have to remove it an I’ll measure it properly mate an come back to u if that’s ok.

No worries on time .. I don't need one but know a machinist who can make one easily.
So keep it together and go "send it"
Ciao!
I have same problem ?
Could anybody that had the same problem say if this procedure is resolutive forever or need to be repeated somehow?
What is official position of YT? Do they change this part on warranty?
Thank you!

Did the noise dissappear after you got the bike back? I heard that this noise is normal and comes from the freehub inside the motor but it's really annoying on bumpy trails. To reproduce it you have to push the bike forward while rocking the crank back and forth a little.

They still.have the bike. They will.give me an update by the end of the week. Only some.people have this noise tho. Not everybody.

My friend has this same clunking noise in the motor. He emailed YT and they sent him a new motor while he continued to ride on the faulty one. He did a motor swap and he never had any down time on his bike and now has a brand new motor.
A well written email will go a long ways in getting what you want.
Yes tried that. They told me that YT US support team usually does since distances makes it more expensive to ship bikes.
I'm based in EU so they insisted I shipped the bike back. Also, all Shimano service centers around here are closed anyways because of lockdown so I figured to send it back and test the process.
