    BBS02 Reliability?

    I rescued my bike back and saw the damage to the Bafang. It was not a plastic gear, it was the main reducing metal gear with several teeth missing. The only way I can see this happening is that something got loose inside and therefore developed severe play between the gear and the rest of the...

    Bafang BBSxx - fault finding and fixes

    I have ordered a front wheel hub drive with torque in mind. It is a planetary drive branded Enduro, an improvement of the BMC motors. The entire kit with controller sans battery, I will use my own, will cost be around mid 900s. In order to make this work especially for the front wheel....I...

    Bafang BBSxx - fault finding and fixes

    The only thing I know is that it was not one of the nylon or composite gears but a metal one, thus of the metal shaving. The guy told that some teeth were missing. This makes me think that through time, something got loose and it developed play and when you have metal parts that develop play...

    Bafang BBSxx - fault finding and fixes

    I got a phone call from my E bike shop and the deal is simple....They found some metal shavings that had become lodged in some gears. The part in question will cost $30 to replace but knowing how these things work, I get the impression that the unit is not reliable enough. One part that costs...

    Bafang BBSxx - fault finding and fixes

    If what I understand from the LUGging you are explaining....if I can pedal and add more speed to the BBS02 in any PAS setting....that means that I am straining the motor? This is something of an eye opener. What you are meaning is that if I can pedal faster than what the BBs02 can provide in...

    Bafang BBSxx - fault finding and fixes

    I had a similar symptom without the comprised battery range about 100 miles BEFORE the mid drive failed. I was stranded between my house and my job and had to call my neighbor to pick me up. One thing I did notice is that the drive was quite hot to the touch. Perhaps it was a signal that...

    BBS02 Reliability?

    My BBS02, factory built on 915, failed after 1212 miles of riding in regular and also wet, snowy conditions. When I was pedaling home, I felt some play in the crank arm....I had been feeling the crank somewhat stick...and when pressed, it would spin again. Not as smooth as when the unit was...

    Bafang BBSxx - fault finding and fixes

    Thanks for the clarification. I will take it to my local shop to get a chain and cog replacement and hopefully the problem with be resolved. Since I have already invested in this mid drive and it is fairly new, I will attempt to solve this in the least obtrusive way possible. I should have...

    Bafang BBSxx - fault finding and fixes

    I will change the gearing one day for a larger cog and see if I can repeat the problem. In any case, if I want top speed, which is almost always the case, I guess the small cog will be chewed up. I will take it to the E bike shop to see if there is some noticeable wear. If I use a larger...

    Bafang BBSxx - fault finding and fixes

    Speedmd, thanks for the heads up. Do you think that the cog and chain wear was due to the excessive torque that the BaFang provides or it is because they were already on the way out when I set the mid drive up? The Santa Cruz HighBall I installed the mid drive in, I fetched lightly used in...

    Bafang BBSxx - fault finding and fixes

    Perhaps someone can elucidate this question I have about the BaFang Mid drive. Mine is a 750 unit circa 2015 I believe. It was installed professionally by a local E bike outfit to a Santa Cruz 29er hard tail. After the week of commuting, I go back and forth work about 15 miles in total each...
