You cannot use your own crankset but you can get a different chain ring. They make Bafang chain rings in a number of teeth sizes. I've seen as low as 42T and as high as 52T.
Installing a Bafang mid drive on a fat bike is actually not possible. Most fat bikes come with a 100 mm bottom bracket. The bafang will only fit up to a 73 mm bottom bracket.Thanks for your reply, Gus!
Yes, I guess that's what I meant, a chain ring. I want to use a fat bike more for the mountains.
I pray no one is dumb enough to pay for that at that price point. That's almost a $1000 price increase beyond the stardard kit and you are only getting a longer axle and a BB extension collar compared to the standard kit. Save the money and just shave the BB down to 73 mm - this only works on some fat bikes.@Gus and @Aushiker @webmonkey8 California e-bikes or w/e it's called, custom makes an extension for the bbos-2 to fit the fat bike 100mm BB.

I hope Bafang just realizes there is a decent demand for the fat bike mid drives and makes their own and offers it at a decent price.
If your not familiar with working out gear ratios sheldon browns gear calculator is an excellent tool, I work out what I need expressed in gear inches, it's more meaningful to me than percentages or gain ratios.I'm interested in the Bafang BBS-02, however I'm wondering, can I use my own crankset? I find that the one supplied with the Bafang kit is too high (teeth). I would like to use something like a 39T.
Sorry, forgot to mention. You saw it comes unpainted? I just did an alcohol wash and a good rub out with coarse steel wool and rattle can painted mine. The finish came out quite nice. The Trek Pure like your Pashley looks better with a chain guard.I ordered one those chainring adapters a couple of days ago glad to hear the quality of them is good. Am converting my girlfriends Pashley sovereign to an ebike with the 350w BBS 01 kit I took off my bike. Am hoping this chainring adapter will allow me to fit the fully enclosed chain guard again. Bike is 3spd SA hub with drum brakes she will be using it to commute to work and back. When I completed the bike will post how it went together.
