    BBS01B motor connections.

    Thanks for this, lots of good info. Ive got a battery that has a 5V 2A USB output, so using a simple relay to switch the headlight will be a simple fix .

    BBS01B motor connections.

    Thanks, do you know what the power limit is that can be drawn from the headlight connector ? Ive got a 4 watt light with a Cree led in it that runs off 5V , and its a decent light, so would be good if I can use it. I guess the problem with the connectors is that there would be so many differant...

    BBS01B motor connections.

    Thanks. Is the headlight a Bafang special type, or can any 5V headlight be used. I guess the power comes from the controllers 5V supply.

    BBS01B motor connections.

    I found out what the extra connections are for if anyones interested. The yellow 3 pin socket is for an optional gear sensor which cuts the motor power when changing gears, and the smaller 2 pin cable is for a headlight. The headlight turns on when the display backlight is turned on .

    BBS01B motor connections.

    Just a got a new BBS01B motor to replace an old original BBS01 and the new motor has more cables going into it than the original. The 3 obvious ones are the battery,display and speed sensor, but the extras are a small yellow socket with 3 pins , and a smaller 2 pin black cable with 2 small spade...

    Differance between original BBS01 and BBS01B mechanically.

    Thanks, Im inclined to do both, buy a new one and try to fix the old one as I hate junking things which have very little wrong with them. Do you know whether the BBS01B motor will work with a C961 display as that will save me a bit when buying a new motor. tnx

    Differance between original BBS01 and BBS01B mechanically.

    Thanks tomjasz for the above links. I came across this article by sheer luck which seems to imply all is not lost. https://california-ebike.com/changes-bbs0102-drive-train/ Have you heard of anyone doing this ? Im tempted to try as if it works its a relatively cheap fix compared to junking the...

    Differance between original BBS01 and BBS01B mechanically.

    Thanks for responding. Yes I know the differances in the gears, Ive pretty much resigned Ill have to get a new motor and in Australia they arnt cheap. Must be a lot of the old BBS01 motors still around that will have to be junked when the Nylon gear dies. The motor itself seems very reliable ...

    Differance between original BBS01 and BBS01B mechanically.

    Have an original BBS01 and the Nylon gear is starting to wear out, the rest of the motor is fine. Ive not been able to find anyone who sells the original BBS01 Nylon gear, and the only one thats for sale is the Nylon gear for the BBS01B, however the 2 gears whilst they look the same are not...

    Walking assist speed . BBS01 + C961 controller.

    Anyone know if this speed can be altered? On my bike its stuck at 2kmh which is far too slow to be useful at all. Changing the bike gears to go faster has no effect as it appears to be reading the bike speed from the speed sensor on the back wheel. If I push the bike faster than the 2 kmh, the...
