Any ideas?
1. doesn't make the noise when the wheel is in the air or if I'm walking beside the bike.
2. Performance is the same
3. Already took both brake's off still makes the noise

Evidently something is rubbing against something else. Either in the motor or outside. If you can't find anything rubbing outside, take apart the motor and see if there's something loose enough inside.
I can't find anything outside.
But when I slowed down the video I see that the valve is always on the ground when the noise happens.
Maybe it's a noise from the tyre
I just changed it after a flat
You forgot the anti-noise additive. Fix-a-Flat doesn't include it because it's ordinarily used on car tires.
Is that a thing?
It's not a tubeless tire.
Or if it is I have a tube in it
Brother, we expert mongolian basket weavers, are fricking with you.
Use Slime. You may have a local version, basically it's a self-distributing thick bright green liquid that contains fibers to plug small holes. You unscrew the valve stem (it comes with a tool) and put in the suggested quantity. Put the valve back in, and inflate.
May not help at all with noises, but will prevent you having to swap in a new tube or patch it everytime you run over a junkie's needles.
Did you inflate the tube before installing it? If you did, it may have stretched and now be bulging in the tire, it would be visibly thicker at the valve but not a lot. You’re supposed to put just enough air in the tube, only just enough to untwist itself, before installing it into the tire.
If you put no air at all while installing it may get twisted inside the tire, will also cause noise.
Get some callipers and turn the whee to see if it’s equally wide everywhere. Also check where the tire meets the rim for visible bulges
Last night I completely deflated it and the re inflated the tube inside.
I also believed it might be twisted.
So I did look inside and it wasn't.
I also tightened the spokes and the noise almost completely went away.
Now I can hear something every forth rotation.
Deflate, then inflate.
Repeat a few times. That will distribute the tube.
Did one of you hall sensor wires get disconnected?
How would I know?
Performance is good it can go 50km
Sounds like bearing noise to me.
It doesn't make the noise when in the air because there is no pressure on the bearing.
It may be difficult to do due to clocking of the motor but see if when it's in the air and you rotate the wheel by hand, can you feel the defect.
I can feel some vibration but I can't feel a certain point or anything .
There is some weird resonance
I have put about 800km on it but to be honest I always had noises.
First it was the front break and I centered that then it was the rear rack and that went away when I glued down the reflector.
This thing is a mess.
It might be the bearing but if you slow down the video you will notice the noise is synchronized with the valve stem.
