No ebike is perfect, this is a thread dedicated to sharing known issues or problems with electric motors from Bafang as well as any help and solutions you know of. You can monitor the voltage level of the battery as well, this way you can make your own estimate, but this requires some knowledge about battery voltage level vs capacity. Hi, first of all, many thanks to this quide, is so helpful. Hi Giel, the reply button was to a previous comment for some reason.. So it is not possible to have PAS 0 as a throttle only setting. It will not try to ramp up the speed and will not stress the motor extra. Example is current at 10% speed at 100% with speed limit set to 20mph. I would however not worry at all about having only 5 assist levels. DPC18 Display If not, try to change them to these values. Hi Giel, Some questions about my bike range. The controller and cooling of the BBSHD are better than the BBS02. The gears are aligned good, nothing is bent. I realize this may be impractical, but Im only using it as an example.

I probably Will order an other Bafang controller if I have to for now. furcifer 10 kW You should match it with your bike, otherwise the speed measurement will be incorrect. Hoping to pedal more and run the motor longer. Regards, Pas0 wont have any assistance when set to 0% current limit. Re: BBSHD Voltage Problem Firmware Update & Instructions The battery percentage read out is determined by your display firmware. So this is not something I would recommend at all. I know both batteries are full because the voltage reads 52.6. But if you would like to have throttle in PAS 0, change the current limit of that assist level in the Basic tab. I believe Bafang has disabled this option in later/current controllers. You can simply use the suggested settings in this guide. I guess I should phrase my question in a different way to shed more clarity. The battery percentage indicator tends to be a bit inaccurate on the Bafang displays. So it will probably have trouble connecting to it as well. By tweaking these settings, you can make the throttle respond more to your liking. The read out % indeed is related to the battery voltage. It is no big deal. I like to take the time to answer all the questions you might have! Hoi Giel, Ik heb een 750 watt bbs02 met een dpc18 display op een 48 volt akku. I did some more research. So riding along in too low of a gear in the effort of increasing efficiency will create the opposite effect since you then will not be able to put in your own leg power. BTW, instead of unplugging and replugging the battery, I turn it off then on. For me on my road bike I normally go around 90-100. If changing it in the menu really doesnt work, you will not have any other option of getting it to display the right %. Did anyone had the same issue or any advice? Therefore the cut-off will also be hit earlier than expected. Just try to apply the power gently in the higher gears to prevent excessive wear caused by those slips. So do make sure the current limit is set to 30A. So I also think its just bad luck. So thats the only way to do it. The kids are really getting into trail riding and an ebike will help me ( and the kids) with our own personal energy levels. So you can maintain that speed. My best guess would be to still try and connect to the firmware. There are quite a lot of steps and you could possibly brick your controller. If you increase the power, the torque will increase, but the speed will increase as well. In order to start reprogramming your Bafang BBSxx mid-drive system, you will need a programming cable. PS: Anyone looking to buy a used BSSHD controller with the throttle mod done. Assist 6 -current limit 80 speed limit 70 Assist 8 -current limit 90 speed limit 50 Assist 9-current limit 100 speed limit 40 In this way on level 5 of the display I have the maximum current with a reduction in speed I also confirm that the two modes of the ECO / SPORT display are exactly the same except for the color change. So speed is not my priority. You can also lower the start up current, this will decrease acceleration but will ofcourse also increase range. 18- ride and have fun! This is not something you can program in the software with the programming cable. Thanks for your suggestion! My kids both have legit mountain bikes as well. Download the correct file according to your Bafang motor version. Furthermore, I would just recommend leaving pas0 on 0% current limit. If it has a torque sensor, the settings will be different. I recommend 36, since this is the default and in my opinion, works perfectly. This makes the Bafang BBSHD amazing potential useless. Second question. Just read the article carefully to find out what al settings mean and if they are applicable to what you want. I suspect this only happens in the highest gear?

Die Mglichkeit, dass Sie etwas braten, ist dann ziemlich hoch. If you have a 48V battery, this should be set to 40-41V. Hi Frank, have you adjusted the settings and if so how did you go? Also make sure that the cut-off voltage is set to 41V (if you are running a 48V battery). I tried to connect with my desk top instead of labtop and quite the same problem except that COM4 is available when i connect the USB cable. Needed for crossing busy streets. LOL 1. on Windows 10 the system recognizes the usb driver (as USD-ser CH340 I believe); on an old Windows 7 machine I have, I installed the driver and its the same name as the one Win10 recognizes.

I can find no explanation about the difference between setting the Current Limit to 0 or 1. Enjoy your e-bike anyway! I really want to make these improvements to my bike! Yes, you could lower the controller maximum current. The only voltage you can change is on the display, which effects the battery percentage indicator. So if you do this, the chance that something will fail increases. Thats why the setting should/can be set to 30 if you have the BBSHD. You can try to reset to your default settings, and see if it still happens. You should verify if the usb cable is actually connected to COM3, you should be able to check this in windows.
