I do not have the MAX PAS setting in the display. Hi, Problem Im able to connect the USB cable, it shows on the configuration programs as COM3, I hit connect it shows connected, but the Read button is remaining gray and no info is coming from the controller. The low battery protection should not be altered, it should be left at the default factory setting for the 36V version. Error code 30 indicates a communication error. I run a XT derailleur with a Sram cassette. There are however a small batch of controllers that are flashed with firmware that wont except 52V batteries. Hi Giel, thanks for your fine work! Programming software - Available by signing up/logging in and then clicking on the Download button above. What you should test is the following: Get a GPS speed app on your phone. This is what you would expect. If you want it to be around 350W, set it to 10A. #1 What is you Bafang configuration? So always move away from a standstill in the same gear as you would do normally without an electric motor assisting you. If you have a 48V battery, this should be set to 40-41V. (sorry for the second message I thought the first one wasnt posted). Enjoy your e-bike anyway! Regards, I should just hold on to your spare controller, it is always nice to have one spare. Definitely check those out! Thats unfortunately just how most factory ebikes will be. In the post, I state that if you set the speed limit to 100% it will stop at your speed limit. I know both batteries are full because the voltage reads 52.6. Do you happen to know what your ratio is? It rode ok on pavement, but was worthless on dirt trails. I am able to edit all of my settings, the bike is read once I open the config software. So for the BBS01, BBS02 and BBSHD. This behaviour can be normal, because when you accelerate, the battery voltage drops. The bafang hub motor kits, unfortunately cant be reprogrammed. It nicely compensates for your pedaling power. Select the COM port that your USB programming cable is connected to. I am a little confused about why your controller isnt 30A. Im only out with the kids maybe 2- 3 hrs at the most in our local mountain bike trails and I would say 3/8 of the time we are just going up and the other 5/8 the time is all about developing the kids skills riding down the trails. Current A was 20A The only option is buying a replacement controller: You should check all physical connections first. Ill try it on 26 first anyways and see if it makes any difference either way. So I tend to do this less now, therefore my drivetrain also lasts longer. This might fix your issue. What is your recommendation. This could be a great tool if they fixed two issues. Hope this helped you, if you have any further questions, let me know. Controller damage can also occur when settings are to excessive. So I would try everything to still connect to the controller. Does this cable and the software also work with the latest version of the Bafang mid-engine: the M420? PS: Anyone looking to buy a used BSSHD controller with the throttle mod done. Do not change profile by pressing M on display during this procedure. Thanks. You just confirmed that this version doesnt have a throttle connection. l. The displays setting will probably overwrite the configuration tool setting. Which often is more accurate than the display does. So say that for example the current limit in assist level 5 is set in such a way that the maximum power while cruising will be 500 watts. 9/100/100. 9 Plug in the programing cable (using the EB-BUS; one end of the EB-BUS is linked to the EB-BUS cable at the controller, and the display cable at the other end of the EB-BUS is linked to the programing cable); Still, you should be very careful with all the settings, always double-check before writing. (Higher start current). This should just work, no setting will change this. Have you replaced it before? You wont be able to hit those ranges with 13 or 17 Ah batteries for sure. Hi, It doesnt really allow for a gradual increase in power. Thanks! Im still experimenting. You then later state that you are looking into a 17ah, 48V battery. Yes I see what you mean . This will only be needed if the motor is very old or used a lot. Yes, you could lower the controller maximum current. For example if you select a small cog ( ex: 15T with a 42T ring) if the current limit of the selected PAS is too low, could it put to much stress on the motor as it will try to ramp the speed to high? So if this is what the bike reads, it is correct. You cant use a 48V battery with a 36V motor and controller. BTW, instead of unplugging and replugging the battery, I turn it off then on. The Bafang BBS02 motor having a power of 750W, it is considered as a moped motor. If you want the bike to give a lot of power but will stop when a certain speed is reached, you should alter the speed limit of the assist levels (or in specific, assist level 9). In that case, how do I make throttle zero on PAS 1? I saved my original settings, but when I went to restore them, the bike does not operate. 30-40Km/h If you want to pedal along at all times, this will limit the maximum speed of your bike to your own maximum cadence. I therefore cant really help you with this. This could be the problem, check this first, if this is set to 48V, measure the voltages and let me know. Changing this setting doesnt do anything noticeable. Can this trottle be used as a full gas or its just for assistance? You are also addressing the fact that you cant keep up with the motor at high power levels due to the high rpm. When I go riding on my own I have my own boutique custom full suspension bike running the latest MTB components. The only reason I ask this is because I think that was the default and I test rode it before playing and finding that I can change the voltage to 52V. My service guy tells me its due to the shift sensor, it shifts under power. If thats the case it will be a waste of money. Herv, The configuration: But if you are able to sensibly shift without the gear sensor, you should be fine as well. with the BBS01 will never overheat the motor but an operator that lets motor speed drop below this risks overheating the motor with a wide range of controller settings. It would have been amazing if you could reprogram the hub motors as well. You dont have to open it to do maintenance like greasing. Would this put strain on the motors electrical system by under powering it? You state that you want maximum torque, but with reduced speed. This is the case with pretty much al ebikes, and especially for Bafang motors. Does it need to do something with him or dont touch him untill it works. You can just assume that if you read your controller settings, that those settings are close to usual stock settings. If you follow the steps of this video, are you then able to set it to 9? Thanks for your time. They are your best chance of getting it fixed without replacing the entire controller. It has a Bafang motor,and LG battery. This setting will decide how much current the motor will draw on startup. A new controller might fix it, but chances are the problem doesnt go away for some reason. DPC18 Display So this is rather strange. I have never experienced this myself however. I have the Ultra and im also thinking about adjusting the settings a bit. Stop increasing when you feel that the power becomes to much for your bike to handle. I, however, do not recommend setting this to 25. A while ago they updated the controller, this became the BBS02B. As of the display, it doesnt really matter which you choose. Hi, Giel! Thanks The Bafang BBS01 mid drive kit includes everything you need to convert your bike including the motor, battery, controller, throttle, display and all the necessary cables. I sometimes notice that my gears slip one teath when coming on power. For a fat bike the wheel diameter is close to 29 inches, this is whats suggested, set it to kmph and change the wheel size to 18. Chain and cassette wear just cant really be avoided completely with such high-torque, high-power motors. It's strictly a feature of the mid-drives. Thanks, That assistance will draw a certain amount of current, which will determine your range. Hello, Make sure to always make a back-up of the factory settings. You should just be more careful if you shift in high power. Connect usb to computer and open up software But in theory you could do this. Hi Giel, I really thank you, not only for the time you have taken to reply to this post but for all the information you supply on your site not only for me but for other enthusiasts. What exactly does the settings file that you created do? NOTE: Not all cables necessarily use the CP210x driver. You can adjust all other settings to my recommendations in this post. The unfortunate thing is I bought a new controller to find all this out!!! It is no big deal. 9c- Disconnect LCD This way, the throttle should give maximum power in all pas stages. I have a Bfang BBS02b 48V/750W. Do you think this is sufficient for my needs as listed above? 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! Have a good day all. 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. I have never checked if these settings can also be used for the M400, I assume that they cannot be used because the M400 is indeed a pretty different motor. Hello, Is any chance to program BBS02 500Watt 36V to turn off pedal assist and use only throttle ? I tried adjusting the resolution, but that didnt help. You can feel this when pedalling as well, if you go to slow, you cant apply any pedal power. My engine is 350W and 36A of batterie (everything is the same as before). The small sprocket in the rear just cant take the power and will slip. So this will solve your problem! How to fix this problem? Could you please tell me if this is how it would work, or what should be changed? Thank you for the great explanations of the settings. Reprogramming your Bafang mid-drive system can improve the usability and performance of your ebike. 05-13-2016, 02:33 PM Karl at electricbike-blog.com compares five Bafang configurations including his. You should check the settings: start degree and stop delay. So such a mod doesnt make sense on the Bafang mid-drive, it isnt necessary. 3. Even with the inability to write and the weird load results? I did some calculation and the speed I got was in fact 30% of max motor rpm, ~40rpm for that cog. This setting decides at which level the throttle will stop. But if you would like to have throttle in PAS 0, change the current limit of that assist level in the Basic tab. The download link wasnt working anymore. This tells me the problem is with the controller instead of the battery and display error. 4 Open the STC programing software. #1 Hi everyone, So I currently have a cheap chinese ebike with throttle and "PAS". Regards, John. You can ofcourse also change it using the programming software. Haben Sie eine Idee wie ich da weiter komme oder Wissen Sie ob die Programmierung bei dem Motor funktioniert? I need to really go through it but it seems they have these well set up out the box. 3/64/41 So I do think that it can prevent you from braking your drivechain and also decrease wear on it. 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. This way you have amazing control over the amount of power. Is is really weird that changing the setting on the display doesnt change the read out. But even with the data sheet of the cell, the 20% voltage is not easy to find. Some moisture in the controller could have caused this strange behaviour indeed. Solved the problem replaced the controller. Beste Gre aus Leipzig Any other suggestions? The main aim is to be able to carry a lot of work gear etc. Would it work if I changed the speed limit of the secend tab(Pedal Assist) to 40 Km/h ?? You are now ready to test your new configuration. Got the cable and averything else but a little scared to use it. So there isnt really a setting that you could change that would solve the issue using the programming software/cable. elaborate it further? If you increase the power, the torque will increase, but the speed will increase as well. Herve There are some displays that support a 52v battery, and therefore can give a correct battery percentage. So you definitely dont have to worry about that. You could unplug the PAS sensor, in order to disable it via hardware though. Only execute the procedure yourself if you are confident that you can do it. I have an ebike with a engine bafang RMG06 48V500W(10). So maybe like you suggested yourself, the bafang controller is defective. For the M400 there is only one controller to my knowledge, so if that one doesnt have the connector, then you are out luck. The possibility that you will fry something is pretty high then. If you can find a replacement controller small enough, you may fit it inside. It will inevitably be some trial and error process. LOL Please check your local laws before riding to make sure you are riding legally and safely. This is the only setting that works correctly, again the default setting, dont change. The situation that you are describing wont cause damage to the moter. Hello, Hi Giel ,in your recommendations for the settings you say to put pas0 to 0% current limit ,100% speed limit & throttle handle designated assist level to by displays command to be able to use throttle only . I am looking to make my 0 level about half as powerful as my 1 level, as 1 makes it too easy for me. Doing it now, will be interesting to see if i notice a sizeable difference in the reading. You can absolutely set the speed limit to 100 for all assist modes, also if you want just 5 levels. Thank you for your instructions, they are very helpful. My screen have always been set to 48V. Most other configurations set both of these items at 1. The read out % indeed is related to the battery voltage. I realize this may be impractical, but Im only using it as an example. The battery percentage is based on the battery voltage. In general, a full 18650 has a voltage of 4.2V @100% and a voltage of 3.2V @0%. sorry for the bad english. A3: Assist 0: set both values to "0" -> no assistance max. Only at really low current limits this could be a problem, like explained above. And do you have the BBS01, BBS02 or BBSHD motor? My kids both have legit mountain bikes as well. Yeah think u are right. Setting the current limit of assist 0 to 0 will just create a mode in which the motor will never activate, this way you can have the bike on safely without the worry that the motor will activate. For example if I limited the first level to only 1 amp, could I do any damage? I think its best that the power goes to 0 when you stop pedaling instantly. I will have a look at the link on the site as well, it should work. You could indeed use my settings for programming, I would however recommend to increase some settings so that you get more power when going uphill. You ofcourse can always try a different pc, to see if this makes any difference. Then you can set the designated assist level to 9 in the throttle handle tab. But like I said, it differs a lot between the brand and cell type. Hello, would you please advice on how to fix an issue, I do not see the Connect tab active. The DPC18 display you have, is the only display that does it in this way, which is rather strange indeed. I would just keep the current limit of PAS 0 on 0 however. Can I still set the Speed Limit to 100 without straining the controller? document.getElementById("comment").setAttribute( "id", "aa94c2f58897d40a9781e630b75a503f" );document.getElementById("ecfd5e2dff").setAttribute( "id", "comment" ); This web page is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to amazon.com. So there indeed doesnt seem to be anything wrong with your battery. You can also learn about all the settings and reprogram the system to your likings. By the way, my controller has been completely recovered. Would it work if the speed limit on the second tab(Pedal assist) was 40km/h?? When I accelerate the speed decreases after a few seconds it is not constant even if I keep the acceleration on and makes a noise as if the engine does not have enough power. While riding you dont have to worry about the low current limit and high-speed (100%) limits. Did you notice that something burned or popped? Currently, Im using the config tool and a USB sniffer to see what serial data is being sent. Not often but 2 or 3 times at a 20km run. 7/88/75 To my knowledge the egg rider basically does the same thing as the computer software. You are good to go! If you search on m400 on this page (CRTL + F), you will be able to find his comments. For that would you set the current level to 100%, and speed limit to 0%? The range is dependent on so called watthours (Wh). When the display tells you the bike is at 40%, it could actually be at 20%. Or did it work for a short amount of time? What I meant with controller programming part is broken is that the physical circuit board responsible for programming is broken inside the controller. Easy to use control pad to turn on the Bafang motor, adjust the Power Assist Level, and change the settings; Plug and play into Bafang . Is it possible the Bafang controller in the motor is defective? Check if you have the same issues there. Awesome website and lots of great information explained in plain english! You could increase the slow start number in the throttle tab. Most of the times the Bafang hub motors don't have these settings available, since they use different controllers (such as Lishui, Kunteng, etc.) I found a tutorial here: https://endless-sphere.com/forums/viewtopic.php?t=100064. So the throttle wont work either. you said the max for BBS01 was 15A. This way, the bike will stop assisting when a certain speed is reached, therefore it will not reach speeds out of your control. You could set it at 5-6A. Bye., Franco If your battery does not have a dedicated switch on it, it will be on if you just have it attached to your bike. I disconnected ebrakes and shift sensor, but nothing happend. A 17Ah or 13Ah will definitely not give the same range, at the same speeds. You just have to have the battery attached, and if your battery has an on/off button, this should be on as well. The percentage indicates at which percentage of the maximum rpm the motor will stop assisting. #1 It is sometimes hard to do research because products change but old info persists. This is normal, the instructions only say that the battery should be on the bike. thanks Hi Chiel, a different question related to charging and not programming, although they are close related. This is the only speed sensor that works with the Bafang BBSxx, this setting is the default. So, yes, something is working, but I wonder if I should be messing with it or not. Do you think that because I did not Connect in the correct order that I may have somehow damaged the circuit board or was it just bad luck. Now the settings for the assist levels. I have an other little problem. Just try to apply the power gently in the higher gears to prevent excessive wear caused by those slips. The error code 30 is probably also the cause of why the programming doesnt work. If it reads to 20A default, this is absolutely fine. Yes you could. You then should look up how you can change the speed limit on your display. This is the correct value for a 48V battery. 26 (to reflect the size of the drive wheel) so that i do not do damage to the motor? Thank you. Initialize - Reads all Bafang Basic/Pedal/Throttle settings at once. I have some problems with my Bafang 1000kw motor. Luna Cycle is taking advantage of this, and is now offering everything that a BBS01, BBS02 or E-rad user needs to upgrade to the BBSHDwhich is the drive unit, controller and sprocket for only $500. The lower this setting, the faster the drive unit will decrease power as you pedal faster. You can always set the speed limit on the display to 25 km/h. My best guess is that changing those settings cant harm your motor/controller, otherwise the controller would limit those settings anyway. I ordered the EggRider V2 it has an Android app for changing the setting. Hi there, i have the Bikonit MD1000, its a 1000w ultra mid drive with an IGH. I am away from the bike at the moment. I know you stated that under the throttle handle you should keep start current [%] to 10, i would like to know if 15 is too much for my set up and also if switching to speed mode instead of current is safe for the BBSHD. And even it goes it can stops at any moment. So thats the only way to do it. Is it normal that process of discharge goes unlinearly. Hi Giel, just read your reply to Ofer problem and I have something similiar! If not, what are my options for using a throttle on this model, 3. When you are standing still, the voltage will not drop, because the battery then isnt loaded. ATTACHMENTS Needed for crossing busy streets. I am unable to get a connection with the controller. You will need to use low assist modes, so you wont cause the battery to hit the voltage cut-off. Now, with the new controller, my bike is slow and the assistance is not the same as before. If you follow all the steps it should just work, therefore I dont know what is causing your problem. Take care not to hit the throttle in too high of a gear in level 9, this can burn out your controller. In the config tool instructions 4th step, it says Plug in the battery of your e-bike (and turn it on). I like your pre-done, configuration file but you only have one for BBS02 48V 750W. Could you clarify your problem? I have purchased a BBSHD and would like to have max power from the throttle at all the PA levels! Windows Laptop / PC - Required to install and run the programming software. Just making people aware as Bafang are not the most informative company.Tom. Hi there was the best setup for bbs02b version 1,Its the newest version, 2. Hello, I hope you figure out another way of fixing it. As for the DPC18 display with 5 assistance levels, I have seen that the coupling of the 5 levels with the 9 levels of the controller are: Assist 1 of the display corresponds to assist 2 of the controller Assist 2 of the display corresponds to Assist 4 of the controller. Any Giel thanks again for listening and I hope this might help people avoid the silly mistakes I made on working with the BSSHD unit So if you set max speed to 100% user will never be able to follow motor at high assistance level. the issue is now fixed and I have been able to reset all the values and save on my PC. So here you will have to choose the correct size for your bike as well. . . So if the current limit is set low, the motor will not be able to turn the chainring with a lot of force. You probably wont be able to change the top speed at all. If the motor is running at 90RPM (at the chainring), it will be pointless to pedal along at 60RPM. HI, Im italian user. It seem that the display voltage settings does not affect to the read out. Im encluding the model of the motor and controller if this info can help determine an answer for me, Bafang MM G330.350 19 / CR X10B250SNU 3.0, Any help in this matter would be very much appreciated.
