I'll double check later but going off their dimensions it's a no go. I'd probably have to tap some mounting holes to get the smallest battery option to fit. Nether of those things appeal to me...
BBS02B/750w: First Build
- Thread starter Gionnirocket
- Start date
Understood and this is what they said regarding using the 100mm in a 73mm bb:
Unfortunately, your only option would be to go with the next largest motor, a 100mm 1000w with spacers to make up the difference.
You will have a wider bike Q factor. Sometimes people have particular opinions about this (as with everything), however other than the Q factor you would need about 20mm of spacers. Sometimes when you install a kit with spacers (especially with this many) it can be hard to get the BB assembly tight enough to prevent movement in the motor on the bottom bracket and may require an additional after market stabilization bar. This is not something that Bafang makes, however there are some aftermarket stabilization bars if Loctite is not sufficient. We do not supply these as they are rarely necessary, however other companies do, such as these:
They sent me a print out template for the bbs02b motor in relation to the bb so I'll pull the crank arm when I get a chance. The good thing is if it were to fit and since it's so close I can put the rear triangle thru it's range of motion to verify it clears. Very impressed with this company...

The template is a pdf file so not sure how I'll ask if they have a link for it. He did say they are still working on it and is in the testing stage but also it's not mine to give. I'll ask though.

Broke the 2k mile mark today on just shy of the 5th month anniversary and all is well in River City.
Very happy with the build so far and looking forward to freezing my arś off riding the second half of the first year

Well it took about 3 more months to bang out another 1000 miles and hit the 3000 miles mark at 8 months total.
Rides are shorter and less frequent due to the weather but the BBS02B is still working well without issue to this point.
The enjoyment and increased interest in riding is appreciated and has led to other upgrades to the bike such as air suspension front and rear as well as tires, handlebars and seatpost.
I don't know if I would do all this again when it's time to replace this dinosaur as I will probably opt for a factory built eBike... But being able to do all this during the Covid shutdown has been a blessing.

1 year in and just over 4000 miles and I can say that the BBS02B has worked flawlessly. A lot of playing around with settings has gotten me to the point where it's hard to tell that you I'm being assisted... unless I want it to be.
My only issue has been my Hailong battery and the dreaded discharge port failure. In all fairness I knew from the beginning that mounting it on the rear rack of a FSMTB was not ideal. I've since resolved the issue with more flexible attachment of the rack and eliminating the discharge port all together by extending the discharge wires outside the case. Since I don't have a need to remove the battery, this solution works well for me.
Anywho... Beautiful day here... I'm goiń riding.
Thanks everyone for your assistance
