Made for a 68mm BB, but you can install it on a 73mm bottom bracket by omitting one of the Lock Nuts.

Green Bike Kit have them as spares!

Kai,
I had the same issue and still do. My speed sensor wasn't working, couldn't see anything obvious. I would just set the assist level before I started riding. Stinks not to be able to change settings without powering off/on and it was nice to see speed and such. I then broke the rear triangle which did in all the wiring, cut through all of them.
Savvas,
I see the extension on Green Bike Kit but not the actual sensor. Curious as to how much that part is. It might be worth it to have it again. Wonder if this is a flawed part. I had the kit for only a month or so before it went out on me.
I emailed CNE bikes and will post their reply about a replacement speed sensor.
BTW - the latest price is now $462 shipped for the 750w on aliexpress. How low can it go?

Rollodo said:Quick question. So I've received the unit, watched the video below, but cannot see him use the outer lockring (the right black one in the pics).
How does that mount?
Will this one do as well?jateureka said:Those lock rings are the same as what I got with my 36V350W units from NNEbikes on AliExpress.
The black one mounts facing out as per your second photo.
You need a C-spanner for the first plain steel lockring. The user manual says to torque that to 30-40Nm.
Then fit the black lock ring with the open side of the collar over the fist lockring. Use a Shimano Hollowtech spanner with 16 notches and torque that up to 25-30Nm.
This new black lockring makes for a nicer looking install
I suspect you would blow the caps in the controller. - Not advised.jpo said:Can a 48 volt battery be used with the 36 volt bafang bbs 350 watt. I am not trying to hot rod my 350 just trying to work with batteries I already have.

Samd got an over voltage error message when connecting 42V to a 36V BBS01 see http://endless-sphere.com/forums/viewtopic.php?f=28&t=50104&p=867139#p867139 . The Bafang software allows configuration of the low voltage cut off but not the maximum. Perhaps maximum voltage is factory but not dealer configurable because the number of turns on the stator relates to the appropriate maximum voltage on a mid drive. Running the motor at higher than intended voltage would make the pedal cadence too high for a rider to match.teslanv said:I suspect you would blow the caps in the controller. - Not advised.jpo said:Can a 48 volt battery be used with the 36 volt bafang bbs 350 watt.

jpo said:Hey Does anyone know what the max voltage the 750 watt 48 volt bafang crank drive can handle. I am looking at cell man"s batteries. the batteries I like are 14s apposed to 13s which is what the system is designed to work with.
The only reason I want to run more volts is because of the size of the batteries he offers. I need a 15 amp hour battery to make my round trip commute.
thanks

krunchi said:I have it on a 29ner mtb
krunchi said:Hi guys,
I just install the 36v 500w bagang unit, it is a bbs02 unit.
I have it on a 29ner mtb, i find the main chain ring too close to the chain stay, i think this is because of the 46t front ring.
Can any one tell me if the machined adaptors out there change the offset of the front ring or do they still place the chain line in the same place as the original bafang chain ring? reason i ask is my chain line is fine and i dont want it any more outward, just want to fit a 42t front ring for more torque and space between the ring and chain stay.
thanks
