No worries. What i’m getting at is that you likely (or me for that matter) wouldn’t notice a difference from most motors of the same size and length and kv. So #1 190kv 6355 vs #2 190kv 6355 - unless tested rigorously - same same.
One might have better bearings, better wires, longer wires or motor output shaft, etc., but performance wise they should be very similar. You’d have to really test the two to see a difference, and i’d bet it would be marginal.
Sticking to a “tried and true” motor like the SK3’s from HK, R-Spec, or Torqueboard’s 63mm would probably all serve you really well.
what kind of riding do you want to do? How heavy are you? Hills or flats? Where are you located?
