Hi,

I'm looking to convert a couple of old but nice MTB's to ebikes.
I've spent some evenings reading this excellent forum and decided a bafang middrive is the way to go.
500watts will do.
On the bafang websitehttp://www.szbaf.com/en/components/motor.html there are 6 versions of similar middrives.
The MM G31.500, 36/48 V, 500 watt. I guess it is 500watt @ 48V, correct?
The MM G31.350 is 36V/48V and 250/350 watt. That makes sense. it is also 400 gram lighter then the 500watt version
On alibaba various sellers list 36V/500watt and 48V/500watt bbs02 kits

Can somebody explain what is what and how one can figure out what is exactly offered with all these sellers?
