Hacking an ebike: how to reprogram the Bafang middrive 

This is a good video for showing how to re-configure the settings... Thank You ! These modifications were just the ticket !

I think I can honestly say I think this this the best tutorial I've ever seen on anything on youtube, ever. So refreshing!

by far the most concise and informative i've seen so far. great work.

Great Video. I did have a 250 watt bafang but upgraded to the 750 watt. When I first tried the bike it was far to fierce in in the lower settings. Your settings are perfect in the 1 - 5 almost exactly mimic how the bike was with the 250 watt motor and 6 - 9 make the most of the extra power.

Thanks for the video was very helpful, I copied your setting and it made an amazing difference thanks again.

hello Steven, Thx for your tutorial. It is really well done. I already watched other videos but your parameters are the best. I just modified speed limit of assist level 5 and 6 to a lower value than 100%... On Tuesday and Wednesday I'll test it on a longer trip. Thx

Extremely useful information, thank you !

Great video Steve and very helpful info

Hi there, great video, can the m600 be programmed with your cable. I have issues with too much speed like you. Especially with take off. Thanks. Annmaria

Thanks Steven for taking the time to make this video. It is an excellent source of information for me. I’ve got a Bafang 500w mid motor on my TerraTrike. I would like to slow it down in general. I am a little uneasy thinking that if I did something wrong I might “brick” my controller. Is there a feature for controlling the headlight/display function? Right now when I turn the headlights on in the daytime the display automatically dims so much that I can’t read it. Also, it would be nice to just have the headlight come on when I am riding as a safety feature. Thanks again!

Thank you I tried to find info but their is very little . The shop i bought my bike from would not show me how to derestrict or program ? So i got the cord ! My BAFANG IS A 1400 WATT MID DRIVE . A little confusing . Thank you !

Thanks Steve,i just hand to replace my controller due to battery reporting issues and the throttle wasn't grunty and it was too fierce off the line on ped 3

Just a heads up. Depending on where you buy the cable and the cable brand you will end up searching online for compatible USB drivers before Windows will recognise the USB com port. But once you have done that it works like a charm

This is the best guide for programming the BBS02, on RU-vid

Thank you for such a detailed explanation. Awesome.

That you for clear explanation! Very helpful, endeed! Subscribed.

This is fantastic. Thank you

Thanks for the info, I have 2 bikes with Bafang middrive's, they're both 350w 36v units but they perform differently. Your info should I hope enable me to get them both the same. Thanks a lot, Rob

Thanks! my controller died and needed a new one so got the newest model and pedal assist one went from 12mph to 17-19mph lol. I bring my puppy with me and try to go slower and it is a pita. Cable should be here saturday, can't wait to slow my recumbent trike down lol

Great job gave me a lot of new info Thank you

This is a great video for tuning your Bafang. The mild settings are perfect for my wife and has enough reserve power in the upper levels. Thanks, good job!

I'm scrolling through the Bafang videos; this is the most understandable yet. But please explain all the settings on the Pedal Assist tab/menu; these are referred to in other videos but I still don't understand them. Also links to download the Bafang Tool would be useful, partic for W11 which (as of June 2023, many have been forced to upgrade).

This is so dang cool!

i'll save everyone the hassle with finding the driver for the cable, take a magnifying glass (if the usb plug has clear heatshrink) and look at the code on the black chip, mine is ch340, spent 4 hours, once i found that it took 2 minutes

Thanks very useful video. I was messing with the controller settings too but i couldnt figure it out. Question: my bafang bbshd has a limit of 500w when it has liw battery. Is there any chance that you know how to fix it?

I purchased an Ariel 52V x class. It’s not a mid drive but a rear drive. The drive is by Bafang. I have the same problem with run away in PA. Doesn’t matter if you leave it in the stock 0-5 range or as Ariel says “change it to 0-9 and that will help”. That’s BS! Ariel says you can’t change the percentage on each pedal assist. I can’t try the programming cable you mentioned because its a female adapter going to the controller not a male. The only hope I have is that there’s a USB port on the LCD screen. If anybody has any suggestions or can point me in the right direction I would greatly appreciate it. Thank you.

Thank you for this video. Very informative.

Thanks for this video. One question though. If I set setting number one to 5km/hour will the motor start when it reaches 5km/h and will it also cut of at 5kmh? Second question, when using throttle can you pedal at the same time?

Hi, Very grateful for you. Great information. Have a good day

just got my cable and programming now, so there are 9 levels in the software but i set my display to only show 5 levels (still goes to max power, just less time ti switch between) so what does it take from the sofware, like what is level 8 in the software, or its not counted ?

Hi, maybe anyone knows can I programming my bafang rear hub motor BFSWX02 500W 48V? What USB programmer I would need?

Any suggestions regarding getting the USB cable to connect to the mid drive. I have a Bafang BBS02B 750 mid drive motor. I have downloaded drivers for the USB 340 cable. I have matched the COM port and baud rate. I have plugged in and powered on in the correct order, and nothing..., Any suggestions would be appreciated.

Great Video. I am thinking of running a throttle-only setup on my current build. Do you think it is even necessary to install the controller and sensors for this? If I do still require the controller, then is there a way to disable PAS while still allowing the throttle to sit at PA lvl 9 for example?

Steven, is the software on the bike or do you have to get that separately? I just ordered the cable.

Great tutorial butI I have a mac. Is there software out there that I can install on my mac?

I've reduced the two Start Current to 1%, was too jerky for me at the start.. much smoother now also Slow-Start mode is the time it takes to ramp up to full current, the parameter you are describing is Start Degree (How long it takes for the motor to react when starting to pedal)

Thanks. Are you implying that with a 25A controller, I can get the full 1000w power out of my BBS02?

7:33 Thanks for the great tutorial. You'd mentioned you wanted to override the throttle regardless of which PAS mode or gear bike was in, would there be a risk of damaging the components if you set throttle power to high?

Excellent video. Thanks

The first cable i bought did not work. It would be recognized by my computer and show up in the com port but it could not read the controller to show any info. I ordered a new one from a different vendor and it seems to be working. I have a 1000w motor with the 52v 19.2ah shark battery. Anyone have a video or post about fine tuning the same setup? 29' specialized rockhopper 2015, btw.

Hey man, spent 40 bucks on the Bafang programming cable but when I plug it into my computer I don't get anything other than the sound of the computer recognising the device. Is this a driver issue or should I be getting a pop up menu? I have a Juggernaut 1000w mid drive. Thanks in advance.

Excellent info man

Great video thanks for sharing it.

So the motors can be unlocked to run at higher speeds but now the other parts of the kit that aren’t rated for use at 1000 watts risk being burned out or damaged? So if all the parts on the except the motor itself were built for the 1000 watt motor then you could clock the 750watt motor up to its full potential safely?

Thank you for this very informative video. I have a Bafang 250w m400 motor. When I pedal I have a feeling that the engine only helps up to a certain point. Than I have to switch into a higher gear ( cassette gear ) and then it helps again. Do you know if there is a setting where I can prolong this help limit? I don't have a throttle, only pedal assist.

Quick question. Is there any programming cable for a Ananda front-wheel ebike engine?

Hello! This cable and softwear works on a rear motor hub Sutto (Bafang) 48v 1000W? Because my PAS not active the motor

Hi, my new Accolmile City bike mounts a mid M200 Bafang motor, with BUS Can; I am told that Bus Can motors cannot be programmed... do you know if this is true? My aim is to skightky adjust the kevek of assistance on each of the 5 levels and unlock the speed limit (15 miles/h now).

Great information! Does this work on the 500watt front drive bafang? I just converted a 29 inch cruiser with front drive and it tops out at only 15mph I feel there is some limit put on it.

There is a Mode in Bafang motor called 'waking'. By keep pushing the minus button it get activated and the max speed will be around 5mph. I admit that 15 mph is too much for level 1, anyway.

Is this also possible with bafang M200?i want to increase themax speed.

Great explanation of the spped settings but your wrong about the 1k motor the 750 is 24A & the 1k is 28A controlled but I agree to keep it lower anyway as the cooling on the motors is insufficient for full voltage to the controllers

does this also work on m800 mid-drive?

I was going through the PDF regarding the speed limit. My LCD shows 28mph as the speed. How would I increase this if the Bafang config tool only allows the max of 40km/hr which is only 24mph. side note, i havent attached my controller to the laptop yet.

Hello Great video, thanks. I have a bafang 750W 20 A, which functions very well but keeps getting error notes: code 30, code 10, etc.... Have you encountered this and know what to do? Maybe it's a display problem (c961), is there a way to reset it to the manufacturer's default?

I have a avaris 3.6 bike but cannot find the 5 pin lead, only one I can see is a 9 pin ahhh any help appreciated

Great video, as you experienced, my Bafang was quite strongly powered out of the box. I was able to follow your instructions and make changes to soften the power at low assist levels. But, then I find my display, a Varstrom touch screen is allow only 5 levels of assist. I've explored all the setting and everything I can find, but can not find the option to change from 5 to 9 levels of assist on the display. I've encountered a "pass word" option. However, I don't have a password and the instructions that came with the system are quite brief. Do you have any suggestions about the assist level option on the display, and/or how I might get through the password setting, change or whatever... Thanks Fred

Superb explanation

Any idea if this software would work on the Bafang M600 model?

Awesome information!! Is there a setting for getting the motor to disengage right away when the pedals stop?

Can you lower the torque settings somewhere i have a belt drive but its recommended max 80nm torque but i want the bbshd on my bike

What does it mean on the C965 UBE LCD display in pas?

Can this fix my dc18 LCD and TFT 750c lcd not working with my sondors mxs?

How do I find the software I put the cable in but the laptop can't find the software you are showing. Do you have a link?

Nica Tanx. will it work on FTF 850C? Do you have a link to bye a cable.

Hi , I have a Jorvik mt7 tricycle with a 250 w mid drive motor bafang M 500. I need to have more strength when I climb a steep slope. So I need a little more power when I m on the easy gear.should I slightly increase the ampere ? How many . Thanks for this amazing tutorial. Gabriel

I know it has been awhile since you posted this but I thought I would try anyway. Great tutorial. I was hoping for some clarification. You suggested setting the throttle maximum to assist level 8 so you don't blow out the motor. The power is set to 100% on the previous page so wouldn't it be throttling at the same level ( 100%) as level 9. Thanks again

brake lever or brake sensor? what to order?? I have mechanical brake sistem on my bike. PLZ HELP

Great Stuff Thanks !

Have you tried on bafang hub motors?

Hi. I don't have a Bafang motor, my one is a 48v 1000w ebike compatible with "SW900" LCD from Aliexpress. Two problems: 1. All PAS levels and settings are too fast, so throttle is the only reasonable option 2. Setting the current limit, doesn't seem to do anything, as I still reach up to 1500W Would I be able to reprogram the silver box with this USB device, possibly if make my own software through reverse engineering I know my LCD uses UART, and connects with a five pin rectangle plug, with five coloured wires (5V, 48V, TX, RX, Ground), adapters exist.

Well done. Thanks.

Very good and clear video! I have 1 thing I haven't figured out yet, my display says "Intelligent" in the main screen like "Bafang". How do I customise this?

I've got a Bafang M200 middrive. With a 5 pins cable. What are thoughts on that?

Would this work on a Kalkhoff with impulse 2.0?

i have 750W bbs02b with 48v 13.5ah battery. should it be possibleto boost it to 1000w or 900.. regarding battery ah ?Thanks .

can you use value over 100% ? example. set 'assist #9' speed limit to 200% . Also, is there a minimum parameter for the motor that could damage something (the other end of exceeding maximum)? A window zone for operation min/max. . Love your settings.

Nice.good to know... I have one question in my mind. It is Necessary to install a gear sensor? If you have, how it affect the performance ? Thank you..

My was factory set to 24. Goes good bends the high cog good

Steven, you didn't talk about the speed limit configuration. Can you configure it to override the limit?

Bought a bb02b 750w a few weeks ago and it runs great, but i was curious as to how it was setup from the factory. So i bought the usb adapter and got the software. Mine was set to 24amp as default, and max is saying 24, not 25 like most out there. Anyways i changed it to 20 just to stay on the "lower" side of things. Thanks for the video ;) Reading tutorials is one thing, seeing how it's actually done and be able to just "copy paste" is a lot easier ;) 10/10

Steven I have american rider 3.0 dose tht work with tht?

Are you satisfied with the low settings for pedal assist 1-3? How many miles per hour or km per hours does pedal assist level 3 reach?

Hi, i have bafang 250w 36v. How to setup in Low Battery protection and Current limit section? Thanks!

Is this also compatible with a BAFANG M300? Or does this require other tools?

thank you, that's good information !!!

Hi I wonder can you turn off pedelasisten because i have a 1000w bbshd BBS03 58v when fully charged and it is very dangerous from start i would gladly turn it off, please if you know how please do a video, my best regards

Great explanation of the software. When changing the throttle response, I see there is also a "Speed Limit" setting that is set to "By Displays Command" . You did not have to also change that? If you were in pedal assist 1 but needed speed to cross the road as the example you give, do your still get full speed?

I have the BBS01B (36V 250W). It has current limit set to 15A. Can I change it to 20A?

if you limit the current will it make the battery more eficiant and will it give u longer milage

You might know this. Can the amps be reduced safely to only use 250 watts max? I only want one bike for private land and also road legal.

Does the software allow for a higher voltage battery pack?

Will the programming cable work on the rear hub motor

Kelly Controllers also are programmable. Contact their support and five them your controller info.

Hi mate, Would you know if there is a programme cable for the bafang green 5 pin triangular cable?

Thanks for the effort and for the video. Can I use a battery with 36v on 750w/1000w motor? You haven’t shown if you can change voltage below of 36v!

If you have a Bafang mid-drive this is well worth doing!

hey mate im having an issue where no matter what i do i cant have the throttle work on 0 assist

Great tutorial but where do I get the program I need? thanks

Hi where can I download the program can you put a link? Thanks, sincerely.
