I've put over 500 miles on my bike fitted with the Bafang BBS02 mid drive kit. It's been going great with minimum maintenance and I haven't had to replace any of the drive train components.

I'm powering my BBS02 kit with the 7Ah 52V Mighty Mini battery from Luna. The range with this battery is around 9 to 16 miles depending on how hard I'm riding.

The Luna cycles BBS02 kit stock chain ring is rubbish. It costs around $90 for a Lekkie ring and is well worth it. As for the gearing, I purchased a 42T chain ring and my cassette is a 9 Speed 12-27T. This gets me a maximum top speed of 30ph and will also gets me up the steepest hills.

You should also purchase a gear sensor because other wise you will have to be super careful when changing gears :)
