You should be able to set those numbers. maar als nog thnx, I realize this is a strange one for sure. 17.5 Ah li.ion DPC18 displa (Limited to 0% current). If the answer is yes and the thinking is that it will make me go faster, will that only be true for pedaling or will it also be true for using throttle only? What I got instead is really slower than that and it could not be the power limit since the motor has almost no load. Thank you for the great explanations of the settings. Thanks and keep good work! To increase the power of the initial throttle push, you can increase the start current. There for sure isnt a different version of the DPC18 display. I still like to pedal . Am I correct in understanding that as of today - mid August 2019 - Bafang makes a motor with torque sensing for purpose-built bikes but not for adding to an existing bike. In order to change the number of assist levels with your display set this to By Displays Command. If Bafang would fix this, it would be an absolutely near perfect motor. Yes, its normal that the discharge goes nonlinearly. Unlike most other people that buy an E-bike kit, my sole purpose is not the range or how far I can go, or how Big my battery is. the app should remember the directory and file name). You should measure your battery voltage, to check if its right. Hope it help you. What you need to check though is if the cut-off voltage in the programming software is set to the correct value. (3.54 MiB) Downloaded 1033 times If it reads to 20A default, this is absolutely fine. #1 Background Doesn't seem to be a lot of info out there yet on configuring the Bafang Max Drive even though e-bikes with this mid drive are becoming more popular, so thought I'd document my experience with it as a starter for others interested in configuring it.

You can only transfer your pedal power to the bike, when you match the RPM of the motor. It will inevitably be some trial and error process. You will often experience that you will have clearance and chainline issues. Do you have a 36V, 48V or 52V battery? The error code 30 is probably also the cause of why the programming doesnt work. You could also lower this value if you want less aggressive throttle. This makes the Bafang BBSHD amazing potential useless.

Am I doing a setting wrong? So if you hit either of those limits, the motor will stop assisting or turn down the power. Both modes will have the same behaviour. Het batterij voltage of percentage is het enige wat is af te lezen. I would try to follow the same instructions on another pc. Is there an aftermarket torque sensor for a bbs02 or bbshd? Alvast bedankt, Luc. Dont change it to anything different. If you search on m400 on this page (CRTL + F), you will be able to find his comments. The drivers are not properly installed.
