Bafang gears are binding
Yep, I'm a newby. I took apart my Bafang fat tire motor (800 miles since new) to grease the gears it because it was starting to make some noise during acceleration (kind of a gear whine). The gears look great and gear alignment is good. I am 72 and drive the bike easy on relatively flat trails. after dis-assembly I noticed that when trying to turn the gear/clutch, the gear/clutch is quite hard to turn and when I turn the gear/clutch it has a harder bind (more difficult to turn every few degrees of rotation)(turning in either direction)(this feels like the nylon gears are too tight on the main motor gear. There are no clicks or notch-feeling) so I don't think it's a bearing). I'm wondering if this is normal? The gears are quite greasy, so I'm suspecting this might not be a lack of grease issue??
Also before taking apart, I noticed that the bike rolls forward easily1, freely, but when rolling backward, the rolling is "stiff" (doesn't roll backward as freely as rolling forward). Wife's identical e bike rolls easily, freely backwards. It's not making any noise yet.
Also, where can I buy a gear/clutch assembly for my Bafang fat tire motor (maybe a 500W motor??)
