Thank you and good day. Great thread I learned so much just reading, Ill get straight to the point: I have m2s full suspension ebike midrive m400 no trottle, 1. https://github.com/danielnilsson9/bbshd-fw/releases, Install In that case the freewheel system will be active. So do make sure the current limit is set to 30A. Only execute the procedure yourself if you are confident that you can do it. With the Bafang BBSxx motor kits, you can easily change the top speed. For a fat bike the wheel diameter is close to 29 inches, this is whats suggested, set it to kmph and change the wheel size to 18. What is your recommendation. I actually like pedaling uphills on my own power! Ex I have 0% on the screen, but I still can ride 20km. Unit is a one of the best built e- bike kits out there but sadly the controller lets it down badly.A lot of kit builder are now moving away from the Bafang controller On the BSSHD and fitting more powerful and user friendly alternative available recently,And we all know support from Bafang is non existent which is unfortunate. I would warn anyone when pulling them connectors apart to be extra careful and avoid pulling on cable as I probably broke them wires when separating to hook up the usb cable. So leave the low battery protection unchanged and set the current limit to 18A. The unfortunate thing is I bought a new controller to find all this out!!! I hope this answers your question :). I understand you can always shift to lower gear but lets say it would increase pedal cadence/RPM to a high uncomfortable rate. In that case the only option to go faster would indeed be to increase the chainring size in front, or to decrease the lowest gear size in the rear (or both). 2) The way you describe this is wrong, the controller doesnt work like that. The biker is peddling at comfortable 60RPM. If you for example set the speed limit of assist level 9 to 50%, it will imply that the maximum assisted speed is 50% of the maximum speed that you have set in the display or in the programming software. With this configuration, there are still some problems: sometimes suddenly, and difficulty in relaunching level 2 to 3 or even 4. BBS02 firmware required - Electricbike.com Ebike Forum The software cant adjust gear ratios unfortunately. Thanks for your time. You indeed will need the datasheet of your specific cell type. Does this cable and the software also work with the latest version of the Bafang mid-engine: the M420? This is what is says in the right lower corner of the program software. You will be better of to ride in a really low PAS mode (5% current limit for example). Yes, the programming software, actually the internal controller firmware limits the maximum to 30A. I have a BBS01B, could that be it? Hi Giel , I have a bafang bbshd . Setting the speed limit to 100% doesnt mean that the motor will try to ramp up the speed indefinitely. Does it not turn on anymore? Just test some settings, if you for example want more acceleration power, change the corresponding setting. I do not have PAS setting in the display.
