motors are fairly universal barring things like bosche or yamaha etc. in genenral most motors are 3 phase wires and 5 hall wires (maybe a 6th for temp). KT is a good option for replacement |
That's what that white wire is? |
it might be |
temp sensor, or some other sensor |
Excuse guys |

Oh no, yeah iirc thats popped cells, I wouldnt use them for fear of fire |
Id be fine with swapping the controller, do you know of any youd recomend? |
KT |
For the cheaper decent end |
Kt is the brand correft? And thanks! I apreciate the help |
KT is shorthand for a Chinese brand forgot the full name. But just looking up KT controllers should work |
kunteng |
There u go |
Kt is the brand correft? And thanks! I apreciate the help |
What’s correft? Sounds French |
There u go |
Oh you mean correct |
Yes KT is the brand |
Oh oop, yes sorry, ive got clumsy thumbs |
And doublw rad thank you both |
Looks like lg m26 |
And hell, even i wouldn't reuse them |
lol one time I somehow accidentally welded onto the side of a battery when I was trying to weld two strips together over it like a noob |
the moment I heard that hiss I ripped the cell off the pack and threw it in the backyard |
like a grenade |
yikes |
Stock #bosch 500Wh battery |
just leaving it here for future reference |
@Akbar dont worry @mark z can salvage it |
Nah |
@Akbar do stock bosch batteries have a bad rep? |
I mean other than the fact they are part of a locked ecosystem |
How locked? How tall are the gates? Drm enabled batteries? |
i think i heard you can't disconnect the battery without having to have it serviced at an authorised center |
that's how locked |
I don't think it's that locked down I've seen people swap them out halfway between long rides. I do wonder if they have drm enabled to stop 3rd parties or people like me hacking shit |
they are drm |
you cant use 3rd party |
maybe i'm thinking of the battery's bms ü§î |
yes it's the bms |
or the motor as well I think |
you can remove bosch batteries if you wanted to charge or store them outside the bike, and also have the 25km/h speed limiter removed at the cost of warranty but maybe that's just on the CUBE bike i tested (EU version) |
that would also make your bike not legal but in my country the police are currently rather clueless on ebikes so it's free reign |
until you trip the bosch anti-tamper |
and you will be stuck at 6km/h as punishment for 90 minutes |
that leading to the new Protip: Do not use 72v charger on 48v battery, or you may bust a nut. |
haha didn't know that was a thing. It's a dumb idea to unlock these bikes anyway, they perform fine as they are |
If you trigger it three times, youll need to go to a dealer to get it unlocked |
If there arent any in your country, youre screwed |
And I think the system is known for being very sensitive and triggering it easily |
^^ pretty sure legit users have been hit by it |
Its that kinda stuff that will make me NEVER recommend a bosch. |
Controller and battery talk via CAN, so you gotta replace *both* if you ever want a 3rd party battery or controller |
You cant even replace a display without having a dealer shop authorize it first with their special programming software/tool |
Yay for the john deer repair model. /s |
Well yes, it was fun to ride but i wouldn't buy one because of the closed system. I've had my eyes on a bbs02 for a while because along with the bsshd i think are the last programmable motors from bafang |
there has been a new motor from them but i think they are keeping the programming on that regulated much better than the cable and janky program you had before, as in only certified resellers are able to program it before sale, or so i've heard. |
I think it was called the m625 |
One of the reasons I went for a bbshd is that and how accessible its spare parts are |
Do be warned, BSSHD loves to change its specs at random with no word |
So measure and buy from dealers who give measurements on their parts |
IIRC things like the motor shaft size has changed over time |
and bearing sizes |
still no torque sensor so there's little reason to get one instead of the older tried and true motors. The motor apparently also must be paired with a battery. The m625 looks like a step back from the bbs02, i hope they don't discontinue it (unless it already is and i don't even know) |
Controller revisions and the bbs02 B version thing |
I thought they had some improvements like weight or something |
If they do discontinue it, im stocking up on parts |
well not really, apparently it's actually heavier than the bbsHD, and must be paired with a brick of a battery. So weight improvements maybe not with this motor |
oof |
meanwhile the bbs02 is like.. 4kg flat? 4100g maybe |
maybe we should move this from #break-it because the only thing that's getting broken here is my heart seeing in which direction bafang is heading but not actual parts |
Yeah lol |
Its sad, seeing them just locking down their system like other companies are |
its basically a bafang ultra with proprietry |
lol at 50.4v |
?volt |
that literally doesn't line up with anything! |
it does |
14S @ 3.6v nominal cells |
50.4v |
Except everyone just calls that 52v -_-; |
weird. |
yes but it's really 50.4v |
I guess. |
No one says 46.4v either |
So @Akbar the removing bosch batteries triggers the anti tamper? |
what do you mean by removing? |
Detaching them from the system |
no |
