My bike is a 7 year old mid tier 500w Bafang G070 rear hub drive with 3,500km. I was just replacing a fender and there is hub noise I had not noted before. It's not binding and the motor operation is fine but my guess might be bearings. The bike has been great and I was not planning on a replacement, but the battery is getting weaker, due for another set of tires, etc. I haven't seen anything clear on bearing service and I'm concerned about getting too deep into the bike. Any opinions on the issue and a possible fix would be welcome. Might it be the gears, cold weather, keep riding it? Thanks
