Hacking an ebike: how to reprogram the Bafang middrive

I go through some of the change i have made to my ebike programing to get the bike to perform the way i want it. Many popular commercial bikes also use Bafang motors and may be fully reprogrammable as well.

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.

I’ve heard that you can configure these to work more like a torque motor, any idea how you would do that? I bike for exercise but at 71 with 4 back surgeries and 2 hip replacements I’m slowing down, I can only go 50 miles on a trike and I’m whipped. Thanks

[@stevenc22]

@@lennymiller7336 Lenny, what do you mean by "Torque Motor"?

[@lennymiller7336]

From my understanding the BBS02 is considered a cadence motor and a torque motor provides assist based on how much force you put on the pedals.

[@stevenc22]

I see. Yeah the Bafang doesn't quite work like that but you can easily program all the different assist levels to get the right amount of assistance so that you still get a good work out.

[@sebastienhubert363]

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

[@RockG.o.d]

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.

Yes of course. You can set a max amps limiting the bike to 250w

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.

No splitter cable. Plus it's best to make small changes at a time or else you can mess things up. Just start with you stock tune and tweak a few things that annoy you.

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?

Also, it would be nice to just have the headlight come on when I am riding as a safety feature. Thanks again!

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?

You can disable PAS on 1-8 and then just program 9 to full throttle

Anyone have a video or post about fine tuning the same setup? 29' specialized rockhopper 2015, btw.

[@bartbaddie347]

Afterthought . . . if you were to revise the video, please highlight that . . . it's the motor/controller that decides when to pedal, not simply the rider. E.g. if you stop pedalling when approaching a Stop (with 18-wheelers rushing past at 100km/hr ) and you click down a few cogs in preparation to pull away . . . and turn a few pedal strokes to ramp the chain to the cogs, you can get a sudden surge in power . . . into the 18-wheelers.

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.

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

[@stevenc22]

Assume you have a 36v battery, you currently only pull 7 amps then for 250w. You could probably do 10amps without much problem. Make sure the m500 is actually programmable. Some of the new motors cannot be programmed

[@chevalierdelorimier776]

Thanks Steven!

[@phd9590]

Mr. Steven, is there also some magic soft suitable for bafang hub rear motors such as H400b 250W 36v. I got such with can bus and speed limit of 25km/h. Using DZ41 (speedometer) I was trying to change it but it seems that it's locked in controler by a vendor. I was thinking about BESST but have no clue it will work. Rgds.

[@stevenc22]

The problem with rear hub motors is often the hub might be Bafang but the controller is a completely different brand and then you cannot use the Bafang tool to reprogram.

[@trevorselch5574]

This is fantastic. Thank you

[@impermanenthuman8427]

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?

[@stevenc22]

The kit can do 1000w. It's just software limited to 750w

[@rickdeckard9810]

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?

[@stevenc22]

No but the tutorial does recommend not putting the throttle so the way to level 9 because going up hill and punching the throttle could overload the controller

[@goriverman]

I cut back the amps to 25 it’s rated for 30. Start at a 10 % and increases as you go up

[@skatygarcia3096]

Hello. Can this process also be applied to my Engwe bike, which has an unbranded motor? I definitely want to try it. In the Engine Pro 2.0 model, the motor cuts off power after 28 mph and continues only with pedal power. Is it possible to remove this limit, or more precisely, to make the motor continue to assist the pedal after this speed? Have you tested this software on motors other than Bafang? Thank you.

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

[@stevenc22]

Code 30 is a communication error. Code 10 is an over heat error.

[@stevenbronstein4686]

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

[@All4Grogg]

His current limit on PAS 8 is 80% of 18 amps, quick math; 18 x 0.8 = 14.4 amps max current; On a 48v battery system ; 14.4 x 54.6v = 786.24 watts @ full battery, 684 watts @ 47.5v 50% battery and 622 watts @ 43.2v 11% battery which is when the walk assist function should be considered to preserve the battery.

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..

[@stevenc22]

I do not have one. A gear sensor isn't necessary as long as you let off the throttle between shifts to reduce the load on the drive train

[@mixerfistit5522]

I have one and it functions perfectly and I don't really notice it, without one if you fail to stop pedalling when shifting you will snap your chain pretty quickly If I hit a bump it'll sometimes activate briefly though, so maybe something to consider if you're riding trails

[@scallahan6426]

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.

Initial response: Got this bike for my friend. kzbin.infoUgkxUiL0GnyDjP32RJdd660sP8mZk4CRLTCJ Delivery was fast. And the friend was surprised I would order it when she had never suggested she wanted anything but the pedal bike she had. She has now ridden the bike two times and gives it a 10 and says it is very fun. We have some hills in our town that are very challenging to climb on a typical bike. But tonight she went up with the pedal assist and loved it. I was way behind on my standard bike, huffing and puffing. Now she is no longer lagging behind me. This thing is powerful enough that a person could go around town without any pedaling. She likes to get some exercise so on flat ground she hits the red button to turn off pedal assist and only uses the twist throttle when she's in a tough spot. The bike looks good. It is really a very nice bike for the friend. Now for me, when I get an electric bike, I'm twice her size and will be looking for a bigger watt motor and battery. But this one is just wonderful for my friend. I am happy with this purchase.

[@impermanenthuman8427]

What about the 250 watt limited motors? Are they also capable of being unlocked up to a greater potential or will that also likely risk damage? A seller told me that with the 250 watt Bafang kit, that all the other parts other than the motor itself will work with the 500 watt motor, so theoretically in places where motors are limited to 250 watts, someone could fairly easily swap out the motor for a 500 watt motor and take the bike off road out in the backcountry and use the extra power to carry gear, then swap the 250 watt motor back in when you want to ride the bike in public again? Legally the motor must have 250 watts written on the motor to be street legal where I am, but if the 250 watt Bafang could be unlocked up to a higher potential safely without needing other higher rated parts which would normally come with a higher rated watt motor then that is very interesting is genuinely safe to do and the motor kit stays equally reliable ?

[@impermanenthuman8427]

In fewer words, what wattage can you safely unlock the motors up to that are factory limited to 250 watt for local road rules? Can they also be clocked up to 1000 watts or just 500? Thanks again

I don't know much about the 250w version, but after a little googling I think the 250w version has the 350w controller on it so you can likely overclock b the 250w version to 350w. No more.

[@MumfordJim]

I think the AMP setting on the 250 will be much lower. Something like the range of 10-15. What every the original is maybe 15? Do not go beyond that. You are only asking for trouble.

[@tempusfugit6820]

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

[@stevenc22]

Honestly there probably is but I haven't looked for it. Check the two guides I linked to, they are way more in-depth

What cable would I need for the Bafang C961 controller, and where can I buy this cable ?

[@stevenc22]

the C961 is your display, not your controller. You need to check which Motor you have to determine if you can use the reprogramming cable or not.

[@calvintanner7897]

I 🤔 I'll know exactly what's going on as far as the controller, the motor, and the display as far as reprogramming. Thank you for your help.

Only if you have a Bafang controller can you use this cable. It's likely you have a wiring issue or your controller isn't compatible with your motor.

Yes. If your battery can deliver 20amp you can increase to 1000w

If you program it does that void the warranty?

The program is direct from the manufacturer. So just using it won't void the warranty. However if you over amp the motor, that could void the warranty

This is probably part of the display itself so would need to be connected to that with relevant software.

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

For 36v your low battery cutoff is 28v and your current limit should be about 10amps.

[@make.and.believe]

I have discovered that my Bafang motor cuts out when the battery power hits 30%. The whole system shuts down completely. Is there a way to lower this in the programming? I'd really love to have 100% capacity instead of only 70%... Also - for Wheel Diameter - is this referring to the front or back wheel? I have a 29inch front wheel and a 20inch back wheel. The speed monitor is hooked up on the back wheel - so should I set the wheel diameter to match the back wheel? BTW I'm running a BBHSD motor. Thanks for your guidance Steven or anyone here in the comments who knows :)

[@stevenc22]

Likely the BMS is turning off the battery, not the Bafang

[@make.and.believe]

@stevenc22 Interesting. Thanks for your guidance! I'll investigate. I know BMS prevents overcharging, but I didn't know it could cause a battery cutoff.

[@stevenc22]

Yes. If batteries are drained below 3v a battery they get damaged. So a BMS will turn off the battery if too high or too low

I'm not aware of that setting? Could the battery be amp limited. As voltage drops amps need to rise and you could be maxing out the amps on battery.
