How To Program Bafang Ultra Torque Settings
Vložit
- čas přidán 1. 07. 2024
- We finally figured out how to program the torque settings on the Bafang Ultra G510 1500 watt mid drive eBike motor for smooth consistent road commuting.
First we'll need to download the Bafang controllerst_torque software. If you can't find it try contacting Frey Bikes, Biktrix, or Luna cycle.
The usb programming cable is the same as the BBSHD, you can buy it on Amazon here: amzn.to/38YXTV8
If you're already setup skip to 3:20 for torque settings.
The most important thing we need to understand is the relationships between:
Start(Kg) and MinCur(%),
Full(Kg) and MaxCur(%),
Return(Kg) and KeepCur(%).
As far as I understand it, the Start(Kg) is how much pressure you initially put on the pedal which then triggers the MinCur(%), which is basically the amount of power the motor will get (I think it uses the Limit current % from the Basic tab which sets the PAS levels). Notice I have the MinCur(%) set to gradually increase across the matrix, this is because I think the Spd0-Spd100 columns represent how fast the pedals are spinning (cadence sensor?)... or it might be the motor rpms? Start(Kg) decreases across the row so less pedal torque is needed to power the motor.
Full(Kg) is how much pressure is on the pedals while moving which then triggers the MaxCur(%). I have all these set to 100 across the board to keep the power consistently maxed out to whatever PAS level is set on the display. Full(Kg) steadily decreases across to require less torque needed to power the motor.
I think Return(Kg) is when you stop pedaling and coast for a bit, then start pedaling again which triggers KeepCur(%). I set this row to match MinCur(%) because it can't be higher and it serves a similar purpose for a smooth power transition. Return(Kg) is set to 0 so the motor will run while ghost pedaling at speed.
The thing about Karl's info is that it's for the Luna ludicrous controller which they don't seem to sell. It might be more relevant to using a phaserunner controller but I haven't gotten that far yet. His post was a crucial help for figuring this thing out.
My prototype is also currently setup with a high gain single speed 58/17T drive train fyi but that shouldn't affect the settings much. I'm planning to throw a Nexus 3 on there for better cadence at speed.

Update: I'm still loving these settings on my commuter, but want to point out a few things:
1. This setup might not be ideal for emtb - couldn't tell you bc I'm a commuter.
2. The motor in this video is 2018-2020 UART version. Bafang is supposedly switching over most (or maybe all) their new motors to Can-Bus which can't be programmed via the usb cable. It requires a special tool and dealer access to special software. Epic fail Bafang! If you don't have a Bafang motor yet, you might want to look into buying one with an aftermarket programmable controller upgrade.
So in effect I could restrict the speeds? To be in line with UK laws? As mine will be to fast.
@@alanandconnielast you should be able to restrict the speed using the settings on the display.
@@eBikeaholic Ok thanks
can confirm theese settings do not work in emtb enviroment. Not sure how one would adujst this for emtb use.
Thank you for the fantastic program . I programmed my Frey AM 1000 with your torque sittings, and it is like having a different ,more fun ,more capable bicycle. The response is natural and smooth. I think Frey should ship their bikes with your torque sittings.
Thanks! I agree, I'm still running these settings for car replacement.
thanks so much for taking the time to do this video
Sure thing, I hope it's helpful. This motor is pretty awesome but the stock settings are disappointing.
Hi, thanks for this very helpful and informative video. Would you recommend these torque settings for a bike with 10 gears for street riding (in particular I have a Frey AM1000), as I noticed you only have a single gear.
I don't see why not.. I upgraded this bike to Nexus 3 speed IGH over the summer and still use the same settings.
Hi ! I have a bafang M400 : can I modify the torque settings with this software ? Thanks for your help
I am wondering if you know what might the issue be. I picked COM3 and the bandrate just cycling constantly and that's it.
Have you modified these settings at all since you posted this video? I just modified my bike to your settings and I love it! Just wondering if you’ve made any changes since.
Nope, not the torque sensor settings... still loving it too. Thanks for the feedback! I did change some of the PAS power level settings for a bit so I could do a low power range test, but then changed them back to stock afterwards.
eBikeaholic I’m only having one issue I was hoping you could help with. You prob don’t have this issue since your bike seems to be a fixed gear but on the highest PAS setting Sport 5, the motor seems to be very touchy and when I’m switching gears it seems to power on before the gears can change. As you can imagine this is a concern for the chain and cassette. How would I go about modifying this so that the motor isn’t on a hair trigger when I let off pedaling to switch gears. My bike is already equipped with a gear sensor.
@@seant1435 hmm, yeah that sounds annoying. I haven't had an issue like that. This bike was originally setup with a single speed freewheel but now has a Nexus 3 speed IGH. I still don't have a gear sensor on it though - I just wait a sec for the motor to ease up before shifting.
It sounds like you might want to play around with the Full(kg) or Return(kg) settings. Those first three (kg) settings in the torque matrix represent how much pressure you put on the pedals. I think the Return(kg) is when you let off pedaling for a sec then pedal again. Maybe try increasing those a bit? Not sure if that would cause the ghost pedal issue again though.
Otherwise, I think the Delta voltage section at the top changes how sensitive the torque sensor is. I haven't changed those but would probably consider trying that first.
Thanks for the great info, is there a way to limit the max torque by nm or foot pounds?
Nice Bike!!! how much did you spent building this monster? and would you consider making another one for someone else?
Thanks! The initial prototype from this vid was about $1500 bc I repurposed most components from a used donor bike and built it at home with basic power tools, no welding or jig. I've made a bunch of upgrades since so it's probably up around $2500 with accessories and whatnot.
I just finalized the v2 design and am looking for potential manufacturing partners... hoping to have a second prototype built sometime this year or early 2022 and maybe do kickstarter if it works out. We'll see.
Hello, Can you share a PAS setting for m620 motor？
Great video. Any suggestions on how to adjust my bbshd pedal assist so it stops immediately after i stop pedaling? The motor continues to run for 1-2 seconds after I stop and it is becoming dangerous, especially trail riding. Any thoughts on how to fix this?
Not sure. You might want to try playing around with the stop delay, current decay, and/or stop decay settings.
Get 4 pistons caliper mate, the armature is heavy likes to spin, put ill try other stop delays .
This is very helplful but I have a problem getting started. The programming cable I have works well with BBS02 and BBSHD and the Pedal Assist Software for them. The Controllerst Softwares only cycles through the bandrates when I try to connect. The BBSHD software connects and will read but not the software for the ULTRA. I have an Branded Bike I am trying to read the settings on. From the controller is the green triangular 5 pin connector which adapts to the round to connect to the display. I saw reference to a CANbus for the bike but not sure if this is connectors or a protocol. Any ideas?
hmm not sure. I have heard of some OEMs starting to restrict them to the CANbus. I got mine as a kit. amzn.to/3hlV322
Hey man, sorry for nagging you but you're sort of my only contact for Bafang software related questions. I noticed in the first page of "Basic" settings under Wheel Diameter it was set by default to 26. I have 27.5 Scwable Supermoto X 2.8 wide tires. I should change that setting to 28, correct? I'm surprised it didn't come from the manufacturer with the correct wheel diameter settings. Also, in "Basic" settings should I set both the Limit current % and Limit Speed % to 100 in every row and column if I want full power when using throttle? By default, the limit speed % is set to 100 across the board but the limit current % is Assist 1 - 30, assist 2 - 35, assist 3 - 40 and so on. Should those all be 100?
It's all good, that's what I'm here for... hope I can be of some help. I don't think the wheel diameter settings makes that big of a difference. I think it only affects how accurately the speedometer reads your speed, so I suppose if you set it to 26" it will think you're going a bit faster than you are bc the wheel will spin faster?
I have all of the Basic tab on factory settings. The Limit current % columns will change the amount of power you get in each PAS level on the display. Depending on the PAS level you're using you will get that much power max from either pedal assist or throttle. If you want full power from the throttle then you need to be in the highest PAS level... I don't think you can differentiate the power levels between pedal assist or throttle but I'm not sure I haven't tried.
Hello, many thanks for the video. But when do i plug the battery?(before/after plug the green connector, before/after plug the USB in computer?). Hope someone can answer me. Thanks
Sorry for the late reply. I've always left the ebike battery pack connected, but the display turned off. I don't think it matters either way... shouldn't need to be connected to battery pack, but I'd suggest keeping the motor/display turned off before disconnecting the display cable.
Is there a way of making the e bike quicker on that software like changing the max speed
You can easily change the speed limit settings on Bafang systems using the display. The diy kits don't usually come speed limited like all the other systems do though, and it won't necessarily make you quicker. The best way to make an eBike quicker is with a higher voltage battery pack, followed by higher amperage controller and higher bike gearing.
what is the outcome ?
before and after ?
also explain the settings more ?
what is the max speed and battery life ?
Before and after outcome is explained at 6:05. I decided to try keeping this video simple by focusing only on the torque settings that I found necessary to change for smooth consistent road riding. Please elaborate on which settings in particular you'd like explained further.
Speed test video is here: czcams.com/video/rKawGBsXu2U/video.html
I'm working on a full review video for the bike / ultra motor but so far with the setup described in this video it looks like it consumes about 60 wh per mile throttle only at full power (1500w).
The current setup also has a high gain ratio (6.1) single speed setup which I believe is also placing a higher demand on the motor and battery, but I'll need to do further testing with a Nexus 3 IGH to prove that.
The goal is to develop a solid workhorse that is built to maintain the flow of traffic as well as tow cargo. I'm not a weight weenie, nor am I worried about paying 12 cents per kWh to charge it since we plan to get solar panels soon.
Hello, I have the same engine, but it is providing power for a short while right after pedaling is stopped, this can be a problem in mountain biking. Do you have any advice resolve this problem? I did lower the Time to Stop of PAS to 5 without result. thank you
I'm not sure, sorry. You might want to try looking up the Frey "smooth" settings... I think those are more suited for emtb.
Hi, I replaced my bafang g510 controller with new one and after that it's not working. Do you know how to calibrate new controller ? need your suggestion, please!!
Sorry for the delayed response, do you know if the new one is UART or Can-Bus?
excellent
thanks
Hello, would you be able to give me the name of an optimal controller and display for my 750w rear hub motor, using a 48v battery I want something that’ll give me some extra UMMMPHHH…. Any ideas ?
Congratulations on your video, my pc can't find the communication port, can you help me?
can't really help with that sorry. I'd try all the common ones which I think are COM3 or COM5 , otherwise google how to lookup your com ports.
The link to the Ultra G510 software is dead ? I cant find any way to download the program to my Chromebook 3 ,
I have the 5 pin connector USB cord.
I need help with a successful link to the Bafang Ultra G510 software.
Chromebooks don't allow us to download programs, only Android apps. I use an old Windows PC laptop to program my Ultra... not sure about Mac.
Where do you get the programing usb cable?
Amazon sells them or Biktrix
I got my befang ultra and as I cant use anything more than 20mph due to laws, so I got cable from Frey. What ever settings I use I can only get about 12mph but with Throttle I can get whatever i want
Interesting. When you say can only get about 12mph do you mean the motor cuts off assist once you reach that speed?
@@eBikeaholic I fixed it and now do about 18mph pedal or 23 with a bit of added throttle
I keep getting error code 10 overheating lately, even sometimes within the first 10 miles on flat ground on a cool day. This is with stock program settings. Doesn't make sense. Do you have any idea why this would be happening? I thought it might be the grease, so I replaced the grease with Mobilith SHC 100 and put a lot in there and am still getting this bullshit error, which keeps cutting off the motor for a few seconds, it really sucks.
Bummer, yeah code 10 is a strange one. What voltage are you running?
I beat this motor up @ 52v, 1500w in 100 deg F and had never got the error all summer. I'm thinking maybe when it gets too overheated it messes up the temp sensor or wiring?
Did you continue to ride it when getting the code or let it cool down first? Did you thoroughly clean out the original grease before re-greasing? How did the electronics look when you were in there?
I've only gotten the error once when I was riding casually at 750w on a cold winter day a few months ago but nothing since - even though I keep beating on it full power.
When I buy another Ultra I'm definitely doing preventative re-greasing it as soon as it comes in. I just ordered some Mobilgrease 28 to get in there before summer hits. Should be similar to SHC 100, they're both rated above 350 F but I don't think they can be mixed.
A few years ago Eric Luna noted error 10 as a 'possible phantom error' for the BBSHD. electricbike.com/forum/forum/knowledge-base/motors-and-kits/bbshd/7747-bbshd-bbs02-error-list
Luna cycle R&D probably has a ton of experience with this when testing their Ultra bikes, maybe try to contact them?
@@eBikeaholic Thanks for the reply. You've pretty much confirmed that I have something malfunctioning in my motor. I just wanted to make sure that they weren't all like that. Now that I know, I will buy a new one from Bafang and then put this defective one in the box and then take a shit in the box, and then send it back and do a chargeback. I don't appreciate giving people my hard earned money and recieving faulty shit from bat soup China.
Do you know any way to program the bafang M600. level 1&2 are all but useless, level 3 WOW off to the races. i want to do the following levels 1=20%, 2=40%,3=60%,4=80% and 5 =100%. supposedly they have locked us out of programing the M600.
Yeah I think for that setup you'll need to find a dealer with a can-bus tool.
I keep losing connection after i click "Read Flash". Tabs get greyed out. 🤦♂️what could possibly cause that? Please help. Thanks.
Do you happen to know how to disable the temperature sensor, either by software or hardware?
I don't, sorry. I've seen some people in the forums using the phaserunner controller which allows you to change the temp settings.
Thank you for sharing! Do you think your “commuter” style settings would be good for any bike equipped with this motor? I guess I was just concerned that your bike appears to be a lot lighter than mine so I wasn’t sure if I would need to modify. Did you also confirm that the controller is running at 30 amps? From what I’ve read, that’s what a non-ludicrous controller should be set at.
Yeah the factory settings came programmed at 30A which is the max for this stock controller. This prototype is actually pretty heavy around 60 lbs. Can't say for sure if these settings are good for any bike, but it should solve the PAS torque sensor problem where the motor gives a big boost then lets off, making the ride inconsistent and underwhelming.
I don't emtb much but the stock settings might be nice if all you want is a short boost here and there. You can probably also just get used to switching into a higher gear to keep up cadence at speed and keep torque on the pedals, but I'm not a fan of changing gears in general and would avoid shifting regardless.
eBikeaholic thank you for the response! Did you find that these settings improved your top speed? Or just the smoothness when commuting?
@@seant1435 I don't think this programming would have an affect on top speed since we can't increase the amps past 30A. Bike gearing, wheel size and battery voltage definitely would though.
eBikeaholic how does bike gearing effect top speed? The new bike I just bought I upgrade from a Shimano 10 speed to an 11 speed. The upgrade is 11/42 to 11/46T. If I’m reading that correctly it doesn’t add anything to the high gears. Just more to middle gearing I guess.
@@seant1435 I like to use the Sheldon Brown gear calculator. You plugin your specs and it gives you a gain ratio. Lower gain ratio will give quicker acceleration, higher ratio will give faster top speed. Either a larger front chain ring or smaller rear cog should give you a higher gain ratio.

www.sheldonbrown.com/gain.html
how is your battery life with these settings?
I did a stress test here... czcams.com/video/ptiuPdwD3Eg/video.html. I'm working on a range test video, but ultimately running at this power needs a bigger battery pack for decent range.
Hallo.
Können Sie mir Helfen?
Ich haibike SDURO Trekking 6.0 Display C
Und ich möchte Daumengas auf bauen.
Ich habe speedchip auf gebaut aber nicht ganz geholfen.
Hat das System Taste für laufn, kann mann bearbeiten in das System schneller machen?

I'm not really sure about the compatibility of components for Haibike systems, does yours have a Bosch motor? You might want to reach out to them directly.
@@eBikeaholic Ich glaube die sestem gleich.
Ja gerne, ich probiere das vielleicht geht.
Danke.
I follow the instruction but nothing happens I can't write flash or even read flash even the controller is connected.
Where exactly are you getting stuck? Are you able to find the correct USB COM port and click connect? Does a prompt pop up saying you're connected?
@@eBikeaholic I find the right COM port coz when I undo the USB the program will show ERROR insert USB and when I inserted back the bandrate keep on running but I can't click the rite flash read flash after entering the program process my motor won't start after connect back to the lcd display.
@@pitikaron hmm that's strange. Are you sure it's plugged into the cable that runs to the motor controller? Otherwise maybe try a different computer if you have one. I'm not sure what could cause that, sorry. Maybe try reaching out to the people that sold you the motor.
Wait a sec, I don't think the bandrate should keep running. After you click connect, does it show all the 'controller info' on the right side like it does at 3:23 in the video?
@@eBikeaholic if I could post screenshot photo comment here I did it so that you'll see. yeah it's strange! I did a few COM trial and it is wrong, error will appear if it is right no error will appear and if I undo the USB this word will appear ( please insert USB to connect the controller and when I inserted then click connect it is connected coz there's no error appearing but the write flash and read flash still I can't click.
my cable is triangular
Guten Tag kannst du bitte ein Download Link schicken oder auf deiner Seite hinzufügen danke
I used the link that's under the second image in this blog post; electricbike-blog.com/2017/11/23/i-void-warranties-hacking-the-bafang-ultra-max-mid-drive-ebike-drive/
I changed the control panel, the speed is too slow, and the engine is hot.
Dang, sorry to hear that. What did you change the control panel to?
@@eBikeaholic The problem was from the engine and it was replaced.
Well, we've received our Frey ebike, & I can confirm that
*the Base Voltage value should NOT be at zero!*
Bafang ships these motor controllers with the torque sensing _uncalibrated._
The _minimum_ value, at _zero pedal force,_ which these torque sensors can output, is around 732 milliVolts.
Anything below 730 mV in the Base Voltage field, is *wrong.*
Far from a matter of preference, _this is literally crippling the torque sensor:_
Set at 0 mV, the first 20% of torque sensing range is thrown in the garbage;
Under any pedal rotation at all, ~"12 Kg" of pedal force is detected!
_Of course the torque sensing won't work well that way!_
*To fix this:*
*Get a reading from the "TqVoltate" field, with no force on the pedals.*
*Add at least +1 or +2 to that value, & apply that total to the Base Voltage.*
*Congratulations! You have just calibrated the Base Voltage of your torque sensor.*
Setting the Base Voltage mV to 757 or higher, should prevent any baseline sensor jitter from being detected as pedal torque. (Unless your torque sensor is unusually erratic. If so, seek replacement as this is a safety issue!)
Bafang Scares me
they have No Factory Manuel or support.as well American service centers with the parts.?
Chinese must want to sell there crap and not support it with manuel's or Honest Customers Service.
I have the BPM imports F1000 ebike and there isnt any material information about this motor? WHY ?????
Have you reached out to BPM for support? As with all the other motor manufacturer's they rely on their dealer network to handle support. There is a Bafang warehouse/office in Las Vegas you can also try to contact.
I bought this motor kit from a seller on Alibaba and yes communicating in a different language and time zone requires patience. I don't bother with Bosch motors because they restrict their programming and are under powered. Do they have US service centers? Have you ever contacted someone in Germany for tech support?
Unfortunately this is the nature of the industry at the moment but yes I also hope eBike manufacturers and dealers reinvest their earnings into better customer support / R&D instead of wasting billions in marketing like the auto manufacturers do.
Bafang has local US support. I skipped local dealers and bought direct from Frey in China so when my motor had an issue I contacted Bafang USA. After only 2 emails Johnny sent a new motor to me free of charge, which I installed. He even relied upon my honesty to send the bad motor to them. Until another company becomes light years ahead in tech, I'm a Bafang customer for life.
the USA Bafang Service center in Las Vegas Does Not Support the Bafang Ultra g510 and has no explanation why ?
