DaDo.Buzz For what it's worth I've installed a few other BBS0X. On the units where I've adjust the settings, I double check the amps and watts using a CA. Thus far none of the watt meters on the display are accurate. I'm using 13s packs and the battery meter/gauge on the display is accurate...

Can anyone advise on where to tap a power supply for a head and tail light? The latest bafang bbso2 has a photo cell on the display that automatically turns on the back light and in theory turns on the head and tail lights when it's dark. Does anyone know where to find the power supply? Thanks Joe

The center hole on the sick bike chain ring is about 4mm larger in diameter than the stock bafang ring so the bafang will not mount on the HD freewheel without significant modification. The 5 bolt hole pattern does not line up either. I wish it did. There is no off set on the sick bike chain...

Since this is a DIY web site I thought I would suggest a cheap alternative. I've taken cheap steal chain rings from sick bike and drilled 5 holes in them to mount directly to the motor. Some care must be taken when drilling the 5 holes but it does work. There is a down side and potential...

Yes it is intermittent. The strange thing about this is that I experience the exact same problem on 2 different bikes and it seems like the controller is "confused" and does not know what to do for just a second. I can never get it to happen on a test ride. It only seems to happen after an hour...

Hi All I'm having a minor problem with my bbs02. It occasionally cuts out for couple seconds. This often happens after the ebrakes cut power. Instead of the power coming back on quickly there is a 2-3 second delay. After a couple of pedal rotations the power comes back on. There is no error code...

One does build a tolerance to speed and power. Slowing down a touch can put things in check and running out of juice anything short of the last climb can be a serious buzz kill. As for the motor out pacing I feel this can be reasonable managed by changing assist levels even if the speed is set...

Can someone tell me if I can fit the bbs02 onto a bike with an eccentric bottom bracket? I will not need to use eccentric to tension the chain so if it rotate the eccentric to lowest spot in the bottom bracket shell it might work. Does anyone know or is the diagram that shows how much clearance...

pjgold With my current settings, which are very similar to kepler's, only difference being I set the keep current between 50-60% and time of stop to 5 and 10 (different bikes), I no longer get the surge when I stop peddling. The motor does still run on but it does not increase power when I stop...

Ken Your records keeping is far more detailed than mine. The surge was distinctive on all 4 of the 48 volt drives I have installed (3-750, 1-500). I have not noticed it on the 350. Maybe it is more pronounces with with the bbso2. Honestly I'm not collecting data like you are, I simply look...

In response to speed vs current conversation. One issue I had with the speed setting is that when I stop peddling the sensor initially reads this as a lower cadence increasing the power. The resulted in the bike would actually accelerate when I stopped peddling. I noticed the highest reading...

I have three bbs0x's a 350, 500(48 volt) and 750. It is very hilly where I live. Two of the systems are installed on cargo bikes. The third (500) on a mountain bike. All work great. I have no issue with any of them. The 350 is smoother and the lower power is safe to use with the nuvinci cvt...

Haha. Yes still working. I did discover that the red wire does not go anywhere. So really there are 5 wires between the consul and controller just like the newer bbso2. ben--b has great pictures of his tap directly into the consul. I may go this route, but don't know how to crack it open. Any...

Arkclark Love the electric yuba Others may disagree but If you have hills gear the bike down to carry your load up the steepest of them at a comfortable cadence. I agree with you that 30+ is fun but honestly too fast. Cars pedestrians other bikes etc. are not expecting it. Great to have the...
