Broken motor gear for acbest 27.5 48vlt 1200watt e bike

[Mickster69]

Im looking for 18t- 39t gear i can only find 18t - 40t gear for bafang motor. I have a unbranded no name generic brushless motor, can anyone help me out with this problem

That's a tough part to look for. Popular motors like AKM and Bafang have parts, but the no name guys are like orphans,

I see you marked and counted them, and it looks like 39T, Count the other ones to be sure, Post on a technical nuts and bolts forum like endless sphere too,
