Not bike, but maybe you guys can still provide input (re: e-scooter wheel bearings)

So, my Ninebot Max e-scooter has a "loud" front wheel, and when I spin it, the bearing sounds "dry".

I have replacement bearings, but then I noticed this:

When I spin the wheel by hand, it will keep spinning SUPER SMOOTHLY and... no joke... can keep spinning for over 10 minutes! To me, that sounds amazing, and now I'd rather not change the bearings.

Does this make sense? I would imagine the same can happen on a bike wheel.

Should I just leave it? LOL
