I do not recommend settings this higher than 10, otherwise, you can wheelie of the bike because of the insane power. Tongsheng TSDZ2 vs Bafang BBS02 Which one is for you? So Ive set 78% for max speed of all PAS and used your suggested % for current limit. Hello Giel, So you can absolutely only change the current limit and have the same recommended settings for the BBSHD. Unusual problem. If you happen on settings that work for you, please share. I tried coms 1 through 4, then even higher numbers. So if you hit either of those limits, the motor will stop assisting or turn down the power. It does not affect to the battery read out on the display that should be logical. It will even increase the lifetime of the motor by using it at lower power levels. So such a mod doesnt make sense on the Bafang mid-drive, it isnt necessary. Leave this setting to 11, changing it can give problems to the response of your throttle. Good luck! This will just result in a decrease in range. BBSHD Voltage Problem Firmware Update & Instructions Who wants to lug their laptop out to the bike or vice versa? Anyone have any more news? The firmware is also compatible with the TongSheng TSDZ2 controller but requires a custom made cable in order to interface with Bafang compatible displays. Hi, just installed the usb diver om my 64bit windows 10 laptop. Or is it to new, so it doesnt exist at the Moment and it can take something?

There is a 36v sticker on the motor. Wenn ich anschlussbelegungen beider Displays htte, wre mir geholfen. So to summarize, your firmware needs to reflashed using special programs and procedures. I imagine you can do it without the controller being installed on the motor but you cant test it? I think that the programming is not your issue, that will probably be set correctly. 5 open up Bafang program software If you want the e-bike to limited to 25km/u, select 25km/u. You could also try connecting it to another USB port and see if it than shows another port. Using this cog I put throttle to max. Maybe some mosfets are blown inside. Velo Fischer ETH 1861. You should be able to get a lot more power out of the Ultra if the stock settings were conservative. What is your recommendation. If any problems will occur in the future, you will be able to fix it. 1 separate those waterproof connectors with care My programming cable will be here Thursday so you will probably be sick of silly questions from me by Thursday evening. or i can get more range with your programming settings?

About the Bafang Programming Resources: The BafangConfigTool.exe is in a zip file you can download on Penoff's Hobby Page and is a huge upgrade to the original configuration tool from Bafang. Use Git or checkout with SVN using the web URL. BBSHD program above 30A? - Electricbike.com Ebike Forum Keep current will decide to which current your motor will drop. John. In that case the only option to go faster would indeed be to increase the chainring size in front, or to decrease the lowest gear size in the rear (or both). Its my first ebike, i rode more than 2000 km since April, but last time I every day rode 500 m abt 20% uphill on level 6 on the throttle on 34 cog, maybe this is the reason. But in theory you could do this. So that would be really simple! 2 Make sure software and Diver are installed and working correctly ( I could only use penoff software on windows 10) Here is what I did. If you then accidentally hit the throttle when you have powered on the bike, and are not on the bike, then it can shoot forward. Yes I see what you mean . Will do a search on the web for more info. Thank you very much for the info. It sometimes help to try another computer, but you already did this without success. Sometimes that means a DIY fix and other times it can mean a recall, software update or part replacement by a dealer. If you want to increase performance further, you can increase the general current limit. We now can indeed confirm that the sport and normal mode are exactly the same on BBSxx systems except for the color :p. Thank you for this post! Giel thanks so much and wow that was a fast response. This is a problem that often occurs on the highest gear. Warning: The firmware should NOT be flashed or configured while the eBike battery is charging! Thank you for this detailed guide, this made by BBSHD perform just like i wanted it to. Hi Giel . If it has a torque sensor, the settings will be different. Great that you liked the post, thanks! I have a bbshd 52v with a 48v battery. You are right! My best guess is that changing those settings cant harm your motor/controller, otherwise the controller would limit those settings anyway. I suspect this only happens in the highest gear? Hi Giel CRR10E4830E105001.1_190413-1.txt Good luck! Then you can set the designated assist level to 9 in the throttle handle tab. Bafang BBS01 250w Review Best street legal conversion kit? This therefore increases the amount of friction, which results in the feeling of more drag. BBS02A - No idea, not tested, not recommended to try unless you have an already bricked controller. So you can maintain that speed. Left it @ 20A. So by setting the 9 assistance levels on the Settings in the first tab (Basic) I found that the Ebike responds perfectly on paved roads and on wide dirt roads, but when the paths become narrow and demanding if I enter level 4-5 to have more power the speed is too high to lead the Ebike safely. So riding along in too low of a gear in the effort of increasing efficiency will create the opposite effect since you then will not be able to put in your own leg power. Hello, Unfortunately your e-bike cannot be tuned. Most of the time when you plug in the programming cable to your pc for the first time, windows will also ask to automatically install a driver as well. Would it work if I changed the speed limit of the secend tab(Pedal Assist) to 40 Km/h ?? I did look for the controller ratings inside this motor though. The higher you set it, the more power it will give initially. Can you still read the old controller? No ebike is perfect, this is a thread dedicated to sharing known issues or problems with electric motors from Bafang as well as any help and solutions you know of. Thanks a lot for this awesome guide. Since you then know that the controller isnt defective.

So maybe like you suggested yourself, the bafang controller is defective. Wow, a battery of 24Ah is massive, nice that you have such a battery! This setting will set the maximum current that the controller will draw. Is your screen set to the correct battery voltage? I recommend 4 because this results in a responsive system. Whats the point? Currently, Im using the config tool and a USB sniffer to see what serial data is being sent. Greetings I have installed your configuration and Im enjoying the ride. You then wont be able to accelerate hard if you are below 40%. That assistance will draw a certain amount of current, which will determine your range. 6 Select the Com port that was assigned to your preferred USB-Serial Adaptor. If you increase slow start, your start will be really slow and jerky. My dealer stated that he didnt know the Luna motor wouldnt automatically adjust for my 52v battery, so he will need to reprogram it. It is normal, that your battery can deliver less power when it is discharged further. It that case it will be really hard/impossible to damage the motor. UPDATE (10 May 2021): . This is how the controller calculates speed. But even if you have the highest gearing on a bike that is physically possible with a BBS02 conversion, so: You still find that pedalling above 50 km/h will not be comfortable. and Id like to use PAS in 5 stages, not 9. Battery is 5 years old but seems normal, issue only started after replacing old burnt out controller with a new Luna controller. then its back to the pre-set PA. I have 48V/250W/14ah Bafang m400.

In general, a full 18650 has a voltage of 4.2V @100% and a voltage of 3.2V @0%. Alternately it is also attached as a .ZIP file you can extract the .bin file from. Only the Bafang BBSxx series can be reprogrammed. You can monitor the voltage level of the battery as well, this way you can make your own estimate, but this requires some knowledge about battery voltage level vs capacity. Thank you for your programming guide, it is clear and comprehensive. In my opinion nothing wrong can be with battery. By setting all the other assistance levels (0-1-3-5-7) to 0 (zero) the controller works perfectly and selecting the 5 assistance levels from the display changes the motor rotation speed. If not: do you know a way to change the settings of the M420? Damage could only occur with very low current limits. But I am pretty sure it uses those levels. If you want to ride on private property you just change the speed limit on the display. If you increase the power, the torque will increase, but the speed will increase as well. Best regards. All these settings are explained in my guide. I have a BBSHD with a 48V battery. Ein Kabeladapter von Higo F auf B hat nicht funktioniert. This is just the limit of the bikes gearing, they were in the first place never designed to run at speeds above 50 km/h. Hi, I did some testing today with the bike on a stand (no load). If the motor has a low current limit, the motor will not have enough power to accelerate the bike from a standstill, which possibly can be bad for the motor. I used DPC18. display controller: 860C, The 860C has a setting for me to change the voltage to 52V (nice). Bafang | Besst I would need the configuration parameters for bafang configuration tool). Enjoy your e-bike anyway! Description. You could try to set strart degree to 0. This setting will decide after what number of steps the motor will start assisting. Yes you could. I dont know the complete code that differentiates it from a DPC18 with only 5 levels and where to buy it. If you find that all other things will not fix the issue, you could try this as a last resort. This could possibly hurt the controller, so be careful with this. The higher you go, the less reliable it will become however. If you hold down the + symbol it will switch back and forth from these modes. 28 wheels If you want this, you should first of all make sure that assist level 9 is set at 100% current limit. The RPM at which the motor will operate at maximum efficiency is, in fact, way higher than the cadence (RPM) at which your own leg power will have the best efficiency. Bafang configuration tool: I have never experienced this myself however. How does 0% current limit get current to the motor? I was really annoyed as I was happy with the way the unit was performing and all I wanted to do was save the settings on file!!!! I prefer setting my display to 5 levels. Set this setting to your wheel diameter, if your wheel diameter isnt in the list, then select the one that is closest to your wheel diameter. I have no experience with this motor in specific, but I think the only settings you can change are the settings that can be changed using the display. I just reprogrammed my controller so I need to test to make sure Im getting the correct power levels assigned to the 9 modes. Hi, Giel When I pressed write flash nothing happened after 5 minutes so I pressed disconnect. Second question. I have a bss01b 250w motor. Im new to the E-Bike Kit and have purchased a BBS02B, 750W and 52V battery. If you have concluded thats broken, I would contact the seller from which you bought it. When the battery is fully charged, it should be around 54.6V. From the product name you gave me, I saw that your ebike has a Bafang hub motor. This also is the default setting. Actually its 10 since there is a Level 0, but that level is (nowadays) a special case that you pretty much have to leave at a special setting and can't adjust. This might fix your issue. To increase the power of the initial throttle push, you can increase the start current. How to fix this problem? Herve, Hello, When i follow the instructions i can click on connect but the read flash tab stays light grey and cannot select it. Current A was 20A If the bike still shows weird behaviour with stock firmware, ebrakes and shift sensor removed it indeed probably will be a faulty controller. Would like to know, can be very helpful for others. If you found this advice helpful, supporting contributions are accepted here. By the way: What is your current limit? 3. Next to that, the problem should also be present before the controller swap in that case. Fiets net klaar, en nu wil ik alles een beetje gaan fine tunen. Hi there, i have the Bikonit MD1000, its a 1000w ultra mid drive with an IGH. It could also be that another setting in combination with the current limit is conflicting. The battery percentage read out is determined by your display firmware. Giel, thanks so much for all the great info! There are three things you can do to improve the pedal frequency (cadence) at high speeds: Get a bigger front chainring. I also found a company who delivers a reflashing service, they are however based in the uk: https://www.electroncycles.co.uk/product/bafang-bbshd-controller-re-flash-for-52v-up-to-60v-service/. BBSHD Firmware Upgrade | Endless Sphere Bafang Hub Motor Review Better than the BBS02? The level 0 is meant so that you can have the bike on, but without pedal assist or throttle. Hi, can you tell me wich setting i must change to have fulltrottle (100%) ability in every pass stage? Bafang 8Fun Programming Software & Guide (BBS02, BBSHD) So the difference is only in the motor controller, they did some improvements. Should I order new controller or first check something else? bafang programming cable.jpeg I would be retrofitting this to a legit mountain bike one of my bikes is a hard tail with a legit front fork, legit hydraulic disc brakes and 1 x 10 shimano drivetrain. Is there any remedy? Its unlikely that it can damage your motor, but it definitely will give an incorrect speed. Lol Also visually check if the programming cable has any obvious defects. It could also be a faulty controller, which cant establish a connection. How did you manage to change the settings on the Bafang M400? Now the settings for the assist levels. Max current: 28A, If 28A is written on the controller, this will be the maximum. Good that everything does work fine. Model: BBS3 Yes Im running 48v. Very much appreciate this site. If you find this project useful, consider sending a small donation to fund further development. De configuratie zit in de firmware van het display. So I dont really see anything that you could do to fix it. The chainline can then indeed be a problem, but this differs from every bike. If Bafang would fix this, it would be an absolutely near perfect motor. Apart from that, I dont see any obvious reasons why it wouldnt work. Last exit 50 km hilly, remaining autonomy 60 km. Do you have any thoughts to my new concern here? Like expected, it has something to do with the controller versions. 2) connect usb lead only To controller Regarding the parameters nothing more than what I said before. Some steps have been broken down into individual steps for clarity; not having one of these units I dont know if Ive done them right. Most of the time, if something is wrong, the load function will not work either. Is there a way to do this as well via serial communication? My 2 front wheels are 20. Fantastic!! I guess I should phrase my question in a different way to shed more clarity. The interesting thing is that YES, the programming does indeed work. I hope I was clear in formulating the question, I am writing to you from Italy But maybe Herve can help you with this, I hope he/she can respond to you. If I know these numbers, I will be able to tell you if gearing/small wheel size is your issue. This way you can have the bike on, without the risk of it applying power. Is there a way I can limit a bbshd 52v to 250watrs for police satisfaction? But again, make sure to back-up the factory settings. This is a safety feature designed to keep the battery in good health. Having such a high power motor connected to a belt drive is tricky in general, which could result in all sorts of trouble. It is interesting that it only started after the controller swap. If you have a 48V battery, I dont recommend lowering this value since it can cause serious damage to your battery. Apart from that, I wouldnt know what could cause the issue. If it says 40%, the battery often is more like 20% charged. User avataramberwolf 100 GW Yeah think u are right. This cant be caused by my preferred settings if set correctly. I understand you can always shift to lower gear but lets say it would increase pedal cadence/RPM to a high uncomfortable rate. I really appreciate your advice . Thank you for your advise. I have the 500C display and it starts in Level 1 PAS each time, is there a way I can set it to start at level zero? 1 )power off battery and unplug Bike display It nicely compensates for your pedaling power. Hi Giel, I found that PAS and the Shimano motor to be plenty for my needs. I have encountered error codes 30 before, where the only fix was to replace the controller. I think that it doesnt have to do with the controller but I could be wrong. Sellers on AliExpress have send out replacements to me for free before as long as youre within warranty time. It is effectively the thing you would do when using the throttle, the motor will do all the work. I also have no experience with this kind of reflashing. So if you look at it that way, it isnt weird that the cadance at those speeds will not be optimal anymore. If the display doesnt work, you can try to engage the bike in this way: https://youtu.be/rdsmplS1N10. Because that ones has a torque sensor instead of speed sensor. What I meant with controller programming part is broken is that the physical circuit board responsible for programming is broken inside the controller. My battery range is 100Km, normaly i use 1/5 2/5 PASS . Thanks for your reply. My questions are pretty basic. I found that this way the motor responds a lot more like you would expect. What is your biggest front gear? I am looking to make my 0 level about half as powerful as my 1 level, as 1 makes it too easy for me. Thanks My question is: Which values do you kindly recommend for me for the low batterie protection and current limit if my motor is 350 W and my batterie is 36A. Note that I havent tried it on the road. I should set it at: by displays command. You were right! Ich kann Ihnen leider nicht mit Ihrem M500 Motor helfen. There are however a small batch of controllers that are flashed with firmware that wont except 52V batteries. You will need to use low assist modes, so you wont cause the battery to hit the voltage cut-off. I have built many custom pedal bikes over the years and know a few things about bike building. A user called Herve, has confirmed that he has reprogrammed his M400 though. Chain and cassette wear just cant really be avoided completely with such high-torque, high-power motors. The reviews on the 104 BCD chainring adaptor seem luke warm as many reviewers say it pushes the chain ring out from the Bottom Bracket too much and thus making the chainline to the largest cog at the back (46T) really off. You cant just lower the current and get the same power, this is physically impossible. No, the BBSHD is designed for 48V. Who designed this thing? 1 comment #2. All these things you can change, just read the article and try to understand what all settings mean. Are you sure you want to create this branch?
