Hacking an Ebike with a phone: Reprogamming Bafang Mid Drives!

[@marcinkopa]

Hi @Stevenc22 I am the author of this application, thank you for showing this. Cheers!

[@stevenc22]

Wow awesome app. Thanks for making it and not cramming it full of ad's.

[@dr.octagon9450]

Is there a apple version?

[@stevenc22]

Not that I'm aware

[@MrLottolee1]

Any update so I can connect to my Avaris and change settings?

[@harveyashworth6285]

My thanks to both of you, much appreciated. Question: I have a new build BBSHD/BBSO3 with a 52 volt battery and the DCP 18 (UART) display programmed with the ECO/SPORT settings. PASS’s levels are listed as 5 in both ECO & SPORT when connected to SPEEED 9 levels are visible. Do you know which levels are assign to ECO or SPORT? I have seen some that suggest this set up only uses odd levels 1, 3, 5, 7 and 9 but no mention of which mode uses them. Any assistance would be helpful.

[@MrPhunka21]

Bought the cable hoping to find someone with a pc to gelp me out.watched this video part way through went to the local electronics store downloaded the app at the counter as i was buying the otg cable rushed home, finished the video made 2 changes pressed the write option . And bamo worked like a charm .lowered my pas cutoff from 200ms to 100ms and changed my throttle response all other settings seemed fine .all from my android phone. Thank you for the video!

[@normandocherty4207]

Many thanks for this well put together video. My old Apollo bike was very erratic and jerky after my Bafang conversion, after watching your video video I bought the cable and set the parameters exactly as you have set yours, my bike is now running really well, couldn't believe it would be so easy . Also a big big thank you to SPEEED!

[@zickzion00]

Could you share the cable and programs that you buy... I would like to try it, but I dont know where to get that cable and programs.

[@daverumsey7629]

Thanks for this video. I hadn't been aware of the Android App.. very useful. The Bafang BBS conversion motors are not programmed well, and reprogramming them as you describe makes them much easier to live with. One comment.. the device on the handlebars that you refer to as the "Controller" is usually called the Display (hence "By Display's Command" as a setting in the program). The controller is mounted directly on the motor assembly, and its function is to supply power to the motor .

[@willdorten6867]

I agree. Idk if this would work with either of my ebikes but it would be nice. I like the way he wants his ebike's assists to be low until the higher levels. My Ancheer tried to throw me off the damn bike back when i first got on it, lol. I had no idea it was going to be automatically set on pedal assist.

[@keithmonk4503]

Good video. As you say this software is extremely solid and a dream to use, used it for 6 months. One suggestion, save the original settings in a file on your android device. (Software let's you do this easily) so you can return to these settings if you find your changes don't suit you. The changes to the throttle settings are a good use of this software.

[@cherylcarey4975]

I had wondered about being able to save the default settings before messing around with them. So, the speeed app has this capability? Or is it the phone you save through. I'm not clear on this. TIA for any help you can give!

[@whatsit2ya247]

I assume you figured this out by now? I haven't played with it yet, I'm still a little nervous lol , is there a way to save original settings before I mess with it from the app?, on my phone? Thanks!

[@harveyashworth6285]

Take pictures of the original settings first, so you can reference them later if you want to.

[@RobertAdams-ly5ku]

@@harveyashworth6285 That’s the way I will do it, good tip

[@mrjceltic]

Both your videos on programming the controller are really helpful. Just finished converting my MTB to an ebike with a 750W Bafang & have same controller 500c. Going to follow your settings as at moment in level 2 it straight up to 25 kilometres, 3 is 35 ks then seem very little change in speed till around level 6 by level 9 its scaring crap out of me lol. Cheers Mardy

[@rdkuless]

I got this and it works.. be careful when making adjustments.. I wanted my throttle to be less aggressive.. went to "throttle" > READ... then adjusted then lowered the "start voltage" lower to .5.... This gave me a error code, 04H... (this means throttle high voltage) which didn't make sense.. The motor wouldn't turn with throttle and the PAS stopped.. OH NO....! I went back and read the help icon... it said it must be at the least 1.10 start voltage to operate or the motor shuts down as not to damage the motor because the current is too low. My recommendation.. only reset one of the parameter at a time.. otherwise, it is almost impossible to figure out the change you made that caused the bike to shut down.. I read somewhere, if you get a error code 04H... disconnect the throttle cable, and if the error code goes away.. replace the throttle.... NOT THE CASE.. you just need to reset the Start Voltage setting to min 1.10... And do not set over 4.40 top throttle voltage or you can burn out the motor... This is a big LEARNING EXPERIENCE... But the app an the adapter cable work great..! Thanks

[@whatsit2ya247]

Thanks for the heads up! I haven't messed with mine yet and comments like this aren't giving me confidence, lol!

@@bradleyemmerson3728 I bought the 48V 1000W motor with the 17Ah battery in the rack over the rear tire. I got it not long after I posted my comment. I put it on an old 10 speed MB my neighbor gave me years ago. I was really happy with it. I've been riding it most of the summer on our local bike trail with a friend. My buddy has an Aventon Pace 500 and I was outrunning him on it. Then his battery would go dead trying to keep up with me too! 😁 Make sure to plan out everything you might need to buy. I had to make a second order because I needed to get the shift sensor for the kit. I also upgraded my old gear changer so it wouldn't tear up my rear sprockets. Overall I'm really happy with it and I would do it again.

In the Google Play Store, I get a message that this app isn't available for your device because it was made for an older version of Android. Any suggestions?

[@truthministries77]

I can't find this app

[@MountainParameters]

Just a head's up for everyone. First thing to note (this will help many that have inquired about other models in the comments) apparently this app is just for BBS series of Bafang motors. In the notes it says, "Warning: the newest 2022+ Bafang mid drive uses a triangle connector not compatible with the programming cable." It can get confusing because I have an early M600 Bafang that is UART (not CANBUS) and it also has the triangle 5 pin green connector. So the take away on this is, if you have a triangle 5 pin connector, it is not necessarily a CANBUS, if it is an older motor (and perhaps not a BBS model), it might be also UART. According to a YT video called, "Difference for Bafang M620 UART and CANbus motor", in order to know what protocol your Bafang motor is, you may need to look at the connectors right at the motor harness and not your display like they do in that video. Apparently they used an 8 pin female for UART, and an 8 pin male for CANBUS, at least that's what they did for the 620 models, so it may be true for other models as well.

[@bockerwright4132]

Great video this is but I'm a little confused. I'm planning on fitting a mid drive this weekend, got everything needed. I have tested the controller (500c) and it's working with the battery, I just connected together what could on the worktop to get an idea of how it all fits. I noticed the controller only has 5 assist levels but this app has 9. How does this work? Should I just average it all out over 5 levels or go ahead and program all 9? It sounds like your riding style is similar to mine so I would like to try to replicate it.

[@stevenc22]

You can change the 5 to 9 in the secret menu. But even if you keep the 5, in the software 1,3,5,7,9 correspond to the 5 levels

Does your battery drain quicker (even if it's a green cell battery) after doing this programming? Can you totally disable a throttle with this? Can you raise the limit before pedal assist turns off?

[@stevenc22]

Yes this probably voids the warranty. The motor will be fine, it's the controller that can overheat and blow out if you program too much amps. You can disable throttle.

@@stevenc22 How can you tell what amount of amps is suitable for your motor/controller?

[@stevenc22]

The 750w and 1000w controllers are maxed to 25amps.

Seeing as it voids the warranty, I'm alittle weary of using it then

[@alistairbarclay3116]

If you have a front hub Bafang motor will this software work when it is supplied with the very basic c 951 controller? I want to make the cadence or torque sensor respond to pedal movement faster. At the moment it is nearly two full revolutions of a pedal for the PAS to cut in?

[@stevenc22]

The c951 is just the display. The controller is the box of electronics in the frame. The problem is many bikes use a bafang motor but not a bafang controller and you need a bafang controller to program anything.

Yes. Easily.

@@stevenc22 Ok 👍 i will try it when i go home. Thank you. I have another ask! I set up the current to 25A , but can i realy get the benefit from that power from the motor, if my battery is 48v 17.5Ah.(840w) Or the battery is too weak ? I didn't feel any difference 😕 last time when i ride it. The max speed is still 44mph (not loaded). What about this options in PEDAL section, Keep Current %. Can i increase that to 100%??

[@stevenc22]

@@ivanpetrov2280 Your battery should be capable of 25amps if the battery cells and BMS are high quality. The Keep Current% is how much current you want the bike to provide when you hit top speed and are pedaling. Once you hit top speed the motor backs off the power just to maintain the top speed. You can increase it to 100% in theory. Please note you are pushing your motor very hard and could blow it up if you arent careful!

nice video explanation, Thanks and can you tell me my bike display showing E002, what is the reason for that?

When does it show E002? Can you take a picture?

[@stevenc22]

@@au1947 Unfortunately i dont know much about the Bewo 250W mid drive. it is a different company than Bafang. I searched for a manual for your motor to find the error code and could not find a list of error codes. I found a manual for a display that says E002 is a communications error. Is everything plugged up correctly? Sounds like bad wiring or connections.

Sorry I don't.

[@TheBikeCourrier]

Hey, any idea why the motor starts forward when I pedal backwards? Kinda anoying (BBS02)

[@BH4x0r]

because it only detects pedal movement, there's no bbs02 for back pedal brakes (if thats what you want), you need a lever brake bike my TSDZ2 doesn't do that because it has a torque sensor and you can't put enough torque backpedaling to activate the motor you cannot fix it on the normal cadence PAS BBSHD, BBS02 etc.

[@asoka2000]

I have the IGO Outlander , would this program work for this type of bike?

[@stevenc22]

Probably not. That bike has a bafang motor but a custom IGO controller and it's the controller we are reprogramming.

[@calvintanner7897]

My motor isn't a mid drive so I'm not sure if this will work on bafang displays.
