Shimano Compatible Cassette with a standard disc brake mount and water resistant connectors. When Luna got their first batch of production Ultra Max drives the first thing they did was hack the controller to put out 2500W of peak power. By proceeding with the following you are acknowledging that you are following these instructions carefully and in full. I think they are the same. Thanks for the article, finally some of the parameters makes sense to me. Insanity is a wonderful thing! The Bafang Ultra mid-drive motor constantly samples relevant information at a frequency of up to 80k Hz via a torque sensor and two speed sensors which are all highly sensitive. Hello and thank you for this great piece of software!!!!! When you start pedaling it you feel like Superman and as you go faster and faster the power just keeps coming till you hit about 40mph. The Ultra Max drive unit with the Ludicrous controller is simply put one of the most amazing drive units ever built. I am on flat road at those times and if I go up in gearing to 4 or higher (the bike has 9 speeds) the motor stays on, probably because I have to pedal harder. At 2500 W you need the metal gear. I tested the drive at 52v but according to Bafang’s website, it will work between 48v and 60v nominal (I have not tested it with a 60v nominal pack). Please DO NOT MODIFY ANY OTHER VALUE UNLESS INSTRUCTED BY BIKTRIX. The Pinion is really interesting and something I might buy-into but much like a Rohloff hub that I also would like to have and while I’m at-it belt drives, where can you get it serviced in your country? California Ebike is a service center for Bafang mid-drive products, as well as custom components, tools, and accessories built by California Ebike under its own trade name. Custom tuned Bafang Ultra torque sensing motor is a V8 among eBike motors. Keep in mind I am by no means an expert in Bafang Ultra Max programming, I’m just some guy who got my hands on the tools and spent a couple hours messing around to see what happens when you change variables. Before you start messing with the settings you should click on the CONTINUOUS GET button on the bottom left and then push down on the pedal. Just got my Bafang Ultra 1000W bike, and I really like it. Compatible with the Bafang BBS01, BBS02 and BBSHD 1000. For example, people like Biktrix in Canada and Frey in China deliver their Ultra based bike with the metal reduction gear. 9. This is a good way to get an idea of what kind of power the Torque sensor is putting out at different pressure levels. Its responding very well. An average size rider can easily hit 30mph using the thumb throttle on flat terrain. Way to go! The pedals and the chain wheel on the Ultra Max are ‘locked’ and spin at the same speed. Extract the zip content to a folder and use the. Also, would you consider the Ultra motor noisy. So, I’ve been talking to Luna Cycle whereby he mentioned your article and potential to improve my situation through your tuning parameters. . I lowered this slightly in the Spd0 and Spd20 columns from the factory defaults but only because it threw an error when I dropped the MinCur% below this variable. Error Voltage Min \ Max: I suspect that these numbers are what will throw an error code if the torque sensor for whatever reason falls below or above these numbers. ------------------------------------------------------------------------------------------------------, Change the values as per the screenshot below, once all values are fed in click on the. Do not think that it has ANYTHING to do with the speed that the wheel is turning because it just doesn’t. Biktrix is not liable for any changes being made resulting in corruption of the motor controller. Any other comments or thoughts on this motor would be greatly appreciated. Sorry I see where you say that all drives that leave Luna will have the steel gear. A few comments/questions. February 05, 2021 21:44; Updated; By proceeding with the following you are acknowledging that you are following these instructions carefully and in full. The Ultra Max comes with everything you need to get rolling except a custom bike frame. You have to type in the port number. If you want to REVERT back to your original settings, Click on File-->Load-->(Select the file that was saved originally)-->Click on Load-->Then click on 'Write' Button. Torque sensor. I suspect that this is the amount of power that the drive unit will put out if you clown pedal along (turn the pedals without pushing at all on them). Thoughts? Pretty much same settings as i have but nice to test new settings. It’s interesting to see what the TqVoltate(Mv) shows depending on how hard you push. This makes your throttle the sole e-bike addition to your bars. Base Voltage: I don’t know what this does, I would leave it alone. Yes, you can change assist (aka torque), Motor wattage (via amps) . The current controller is very powerful and there are vendors and Bafang partners who have been able to get as much as 2500 peak watts flowing through this with no problem A YouTuber 'Mark my words" has saved me a job in making a good video explaining how to program the bafang Ultra M620 motor. So what you CurDecy : I didn’t mess with this setting but it is probably Current Decay which is how fast the power drops off as you start pedaling faster and the crank spins faster. You can certainly program it differently so that it will put out a lot more power from a standstill, but it will feel pretty lurchy and not smooth and refined like I think that a torque sensing mid drive should feel. Hi Mike I didn’t upgrade a thing, I reprogrammed the software. In order to program the Ultra Max, you will need the latest version of the Bafang programming software which you can download here. The settings are quite different than Karl’s Special Sauce. I like to drive very compfortable, so i dont need more then 250 watt and more then 80 Nm. View and Download BAFANG DP C07.UART manual online. I would not change them. After reading both the Bosch and Bafang review you realize both motors are great. It is paired with the 850C color computer console which allows you to program up to 9 levels of assist. So i have reprogrammed this ultra max a lot and nothing works… The only thing I haven’t gotten into is the torque settings..I’ve changed a few things but not a lot…. Very much an on/off experience. Actually it depends on the provider. With the 1000W nominal Bafang Ultra Max drive unit all that has changed. There is different version of the Bafang program for the torque sensor motors, but I couldn’t get it to work with my BBS02. 250 W Nylon works fine. This turns the ho-hum 1000W  Ultra Max into a real 40mph drive unit to be reckoned with. Hello together, i bought an frey am1000 ebike with the ultra max. The 1000w BAFANG ULTRA MID-DRIVE MOTOR is a true marvel of engineering, over 1600w of peak power and 160nm of torque allow you to accelerate up steep inclines like never before. No, the stock 1500W Bafang Ultra Max has a crappy Nylon gear that I hate. Thanks to Roshan from Biktrix for sending me these files. To use just unplug your BBSHD or BBS02 display, and plug in the black box. It felt too much like the BBS02 which is half the cost and half the weight of the stock 1000W Ultra Max. According to Bafang’s website, the Ultra Max spins at 150RPM (with torque only, no throttle) max at 52v. Bafang employs about 700 staff worldwide in eight locations. I am in the UK and I have just converted a Giant Roam using a Bafang BBS01B. So far, so good – but I have a question relating to the PAS settings in so far as I am preferring to have 5 levels in use, rather than 9m levels: The Bafang PDC-14 manual states that using 5 level: 1=1; 2=3; 3=5; 4=7 and of course 5=9. I’ll stick with regular HD that l can rebuild and bolt on anything. Change ). Enjoy the videos and music you love, upload original content, and share it all with friends, family, and the world on YouTube. For those who aren't aware, most Bafang motors are programmable (beyond the parameters of a display function). If i am correct, the special sauce file is to both standard and Ludicrous version, besides the 30 amp current? This custom mounting plate can be welded to any aluminum bike frame. Although Lunacycle guards their 2500W BBSHD Ludicrous controllers pretty closely (gotta buy a whole damn bike), they have decided to offer the Ultra Max Ludicrous controller and drive unit to the public and it is available right now here for $750 + $250 for the Ludicrous upgrade. Post was not sent - check your email addresses! Conclusion. This article is going to just breeze over the first 3 pages of the programming menu as most of the variables have the same effect as the BBSxx programming and are already outlined in this article. But all seems like guesswork. Change ), You are commenting using your Twitter account. With the Ludicrous controller the amps are doubled and it ships from the factory with Limited Current(A) set to 25 amps which really delivers about 50 amps to the drive. All right reserved. Just wondering if there are other firmware controls handling the heat and power mgt that can’t be adjusted…which Luna suggested might be an issue. Although I liked the concept of a high power torque sensing mid-drive, I wasn’t crazy about the implementation. Does this mean that the steel gear comes with it by default? But Alas this one is better IMO. The sensor on the PAS page should be set to BB-Sensor-32, This screen is the same as with the BBSxx drives. Stop and retry if it doesn't come off in one go. Is it my computer that is the problem or is it a software issue? I received Controllerst_torque software from the dealer for my bike but the port is blank when I open the program and I cannot access the controller. Modified 1000w BAFANG Ultra. I, like Matt (above) have the M2S Ultra Fat FS bike with the new Ultra motor. MaxCur(%) : This is a percentage of Limit Current% from page one based on the current power level setting on the PAS display that will be applied when Full(Kg) pressure is applied to the bike based on the speed that the crank is currently turning (Spd0-100). If you want more explanation on what these settings do, then you can check out the hacking guide which outlines each setting individually. Custom tuned to 750W, 28mph top speed to comply with the legal laws, it has incredible low-end torque and acceleration. Click on File and then Click on Save as shown below; Now give a name to your file as shown below and also note where this file is saved on the computer (take a screenshot/ picture from your cell phone of this screen). Bafang, one of the leading manufacturers of e-mobility components and complete e-drive systems, has been developing components and complete systems for electric vehicles since 2003. Check with a Biktrix technician before making undocumented changes to these settings. 3. But, they also indicated the Ultra motor is still really a beta platform that they dont consider as strong or reliable as the BBSHD. Full(Kg) : When this amount of pressure is on the pedal you will get the MaxCur% of total power based on the speed that the crank is rotating. The standard $20 programming cable is all you need to customize your Ultra Max programming. At the factory, the MaxCur% was set to 100 across the board and the MinCur% and KeepCur% for the first two-speed settings were much higher. The one thing that all these ‘low power’ drive units have in common is that there is absolutely no way to program the drive unit to do anything much other than what it is set to do from the factory. Does the production unit weigh less than the prototype? This variable could be a replacement for the Start(Kg) when pedaling is briefly interrupted and then restarted again. Investor, Consumer & Crowdfunder Beware : Is The Entire EV Industry Becoming Fraudulent? I’m having the same experience. Many of these defeat devices plug-in between the speedo and the main drive unit and halve the speed that the drive unit thinks you are going at (so when you are going 20mph the drive thinks it is only 10mph). Im considering applying most of your tweaks to my MS2 All Terrain Ultra which is using the Bagang Ultra 510.1000 mid drive kit. This is a percentage of the Limit Current% from page one based on the current power level setting on the PAS display that will be applied when the Start(Kg) pressure is applied to the bike based on the speed that the crank is currently turning (Spd0-100). It’s currently a bit busy. Although these settings are probably fine with the stock 1000W Ultra Max, they were set way too high for the Ludicrous controller. The page you have all been waiting for, this screen has all the new goodies on it. Could you please provide the source code files for the Software with Torque tab? Warranty may be void if you program your motor yourself. Thx Karl.. are you using/running any stock only Ultra units or just Ludicrous controlled? This means that if you are miles from home you’re going to be stuck with cycling the power on your ebike so you can get 1 minute of riding then continually cycling your drive unit every minute the entire way home. What the software does is takes this mV (millivolt) input and maps it to kilograms and then the rest of the settings use the kg variable NOT the mV input. This will give you the best climbing power as well as the highest top speeds. Is it possible to make the Eco mode pedal assist only go up to 25km/h and the Sport mode work like it does (no limit)? I just opened that program and noticed this things…. Biktrix. The Bafang Ultra Max is the only Torque sensing mid-drive that I know of that is user-programmable I tested a prototype 1000W Ultra Max about 8 months ago and found it a little too heavy and a little underpowered for my taste. The Ultra is a fringe motor for sure, the BBSHD is much more popular. Crappy programming by Bafang, read my other BBSxx programming article. It certainly feels that way. its like make it hard when you are struggling but then give you a boost when you are not!! I believe the way it works is that the program splits up the incoming voltage so that is it changes by a certain amount then it assumes that there is that amount of pressure on the pedal. The first page of Karls special sauce, At 25Amps the drive unit really means that it’s running at 50 amps (the power setting is halved on the Ludicrous controller). $1,899.00 This powerhouse provides maximum power to the rear wheel. Skip to navigation (Press Enter) Skip to main content (Press Enter) Enquiry ⁄ 0; EN. With Luna drives we always program to our own settings, our own preferences to the style of bikes and drives we offer. When I am pedaling in PAS 1,2,3 or even 4 or 5, the motor seems to very quickly cut off and on. I swapped out that controller for an 850c… It is way better and allows you to adjust the PAS for levels 1-9..also in the setting set the min cur% to 3 in the torque settings, Pingback: Everything I Own Is Now Obsolete : Christini AWD Fat-E Ultra Max 2XL Snowshoe Ebike | ElectricBike-Blog.com, Hello Karl I have hills where i live pretty good size ones, what battery would you suggest to handle hills so i can climb as well as get range. ... Warranty may be void if you program your motor yourself. These are the ‘stock’ Bafang settings and you should use settings similar to this if you have a non-Ludicrous controller. Going over 40 mph on a bicycle is pretty terrifying, but this is the first and only torque sensing mid-drive on the market right now that will put out this kind of power that I know of. I have started a project where I want to communicate/program my e-bike with the Arduino. In my country the maximum speed allowed is 25 km/h with pedal assist. My weight is 200 lbs 6ft1 tall. Treat your ebike like it’s a chainsaw and you’ll probably be OK (assuming you aren’t a chainsaw juggler). I do have the G620 ultra drive but its stock at the moment. Did you ever figure this out? Programming Bafang mid-drive Motors - BBS02, BBSHD, Ultra (M620, G510) Menu Bafang Controller/ PAS Programming Guide Follow. This article is about understanding the programming for the Ultra Max and understanding how to change your programming to get the most fun factor out of your drive unit. Thank you, I am a little confused. Download the software from the link below the article in the attachment. The Bafang Ultra Max is the only Torque sensing mid-drive that I know of that is user-programmable. Once the battery is removed try and turn on your Bafang motor on with the power button (though the motor won't power on because there is no battery it should use any residual power in the system so it doesn't spark when you fix the connection). Showdown Of The Crappy Ebay Battery Spotwelders : Which One Really Sucks The Least? Bafang released the source code and Stefan Penoff (Penov) took it and made it better. If you want to download Karl’s special sauce instead of entering in all the data manually then you can download this file and rename it from .doc to .el and then select FILE->LOAD from the Controllerst_torque.exe and then browse to find the .el file. For me its importend to have a silent motor. We provide friendly sales support and technical assistance. KeepCur(%) : This number must be equal or less than MinCur or the software throws an error. No smooth variable application of power…and at times significant delays in applying any power assist why pedaling reasonably vigorously. MAX Drive System. If it was easy then everyone would be doing it, right? *ouch* Remember, safety fourth. Hi Karl, that is a great article on the Ultra. I have a question/problem: The pride of ownership of something that you built and programmed yourself is something that you will never get with anything you just purchase outright. MS2 talked to their Bafang rep who told them Bafang recently updated their heat and power mgt algorithms to reduce motor failures…which may be whats causing my issues. ( Log Out /  Connect the USB plug on to your computer and the other end to the Umbilical Plug (Green) as shown in pics. Delta Voltage: I messed around a bit with these numbers and they are a way to change the sensitivity of the torque sensing unit along ALL the speed ranges of the motor. Built to be a high performance down hill full suspension electric bike, with a Bafang G510 Ultra Mid Motor, and powered by a 60V Battery which can ensure a decent range of about 40km depending on how you like to ride. Hi Karl, If I coast or stop and wait…power will come back a bit and then fall off again. You need the back pressure in order for the torques sensor to properly register voltage. Thanks, I can not connect to my computer also, I see no ports listed on the pull down menu everything is blank. I didn’t spend much time messing with this screen’s settings. The programming cable allows you to hot rod your BBS01 & BBS02, and BBHD controller, and play with all the different setting available. If you like living on the edge then don’t let me stop you, but I tested this drive extensively at 50Amps and I can say that it is plenty powerful at that power level. emimobilebox says: 10.10.2016 at 13:20. Actually, you could get your Steel Driver by contacting Bafang directly. By lowering these numbers you make the torque sensor more sensitive and responsive to foot pressure, by raising them you make it less sensitive to pressure (so you have to push harder to get the same results). It does not seem to have great power going up hill either. My display is the 850C. Disconnect the USB cable and very very carefully pull the Programming cable out of the Umbilical plug, be patient take your time. I changed the setting from the Spd0 column from 100 down to 6 which greatly reduced the jerkiness of start in the highest power levels. That drive unit was several pounds heavier than the BBSHD and yet it still only seemed to produce about the same amount of peak power as a BBS02 (about 1400W). A mount like pinion that 90% can’t weld on any cycle. On the Device Manager please check if the COM port is read/ allocated to the device. The Lunacycle version is made of magnesium which is 3 lbs lighter. Don’t worry about sport mode. Hi, I got a RobotDyn Mega 2560 Pro Mini (Embed). Biktrix is a Bafang mid drive focused dealer out of Canada that is selling an Ultra Max with their Juggernaut Ultra FS sold here for $3599. Incidentally, the prototype version of the Ultra Max did not have this problem and continued to function even with a non-functional speedo, go figure. I spent a lot of time messing with these settings and as near as I can tell the Ultra Max seems to ignore most of the settings on the Pedal Assist screen. We ship all products within 1 business day. The Juggernaut Ultra FS is the latest in the lineup of Juggernaut ebikes from the Canadian company Biktrix. Before you keep reading this article, you should reference this article on programming the BBSxx as there is lots of information on the cable and the quirks of the programming software. Also, the pedelec assist is quite dismal. I lowered the numbers from the stock Bafang programming on this variable in both the Spd0 and Spd20 column. The Ultra Max spins at different speeds based on what voltage you’re driving it at. To program ‘Karl’s Special Sauce’ the ONLY numbers I modified from factory settings were MinCur%, MaxCur% and KeepCur% in the Spd0% and Spd20% columns. But I ran in to issues instantly, when just trying to forward the serial communication via the Arduino. I just bought frey am 1000 ebike (with ultra motor) and I already have little bit higher settings: Basic settings: Low battery protect 41 and limited current (A) 30. Do it at your own risk and don’t come crying to me when you break it (this is why we can’t have nice things). Capable of incredible 160Nm of torque, this monster of a motor can make any hill into a downhill adventure. I can feel the power drop off noticeably and also see it on the watt output monitor. Return(Kg) : No idea, but my guess is once the bike is moving and you stop pedaling it takes far less pedal pressure to get it moving again. think, is for me the nylon gear better, or is there no Difference in acoustic between nylon and metal gear ? The settings I am showing in this article I’m going to call ‘Karl’s special sauce’ for the Ultra Max. The throttle is the same way…on/off.
