Having fitted and worked with a Bafang BBS02 for the last couple of days, I have noticed the reasons behind the poor chain line.
You don't really spend a thought on bike geometry, until you start fitting motors.
Bafang have played it safe with the offset on the 48T, otherwise the teeth have a strong possibility of touching the chainstay.
This has led to problems with some bike's chain line, where the front chainring offset is just not great enough for 1 or 2 of the lower gears to be used.
Bafang are quite elusive when trying to find out specific detail about their products, so I wonder if anyone can help answer this:
With the stock Bafang chain rings, which I believe range from 44T - 52T, are the offsets all the same, or do they get bigger as the number of teeth get less?
