I spent many hours for internet research, from Chinese sites to different forums all over the world. I am one step ahead to give up.
I have a Bafang SYX-D01F 250W Front hub Motor with overall 3000+ miles . Now the 3 nylon gears are broken and I need a replacement kit. The gears of this model SYX-D01F are very special with a dual reduction gear feature, see attached picture. All hints , comments or ideas are appreciated. There are countless kits around for many different Bafang models but nothing fits to the SYX-D01F
