Is this a normal sound??

​

Recently, like a couple of days ago after I fixed the rear wheel of my scooter, it started to make this kind of noises when it goes to a certain speed or when is full throttle up to certain speed, after that the scooter keeps quiet as usual.

It's a Xiaomi Scooter 5 Pro if needed lol

What I suspect is that it might be a lose piece but externally and around the motor I don't see any lose piece, everything is tighten as it should, which I suspect there's something wrong with the motor itself, should I be worried?

(Ignore that bump I js hit myself with a chair while filming, nothing related to it lmao)
