    Safety speed with your EUC

    Hello, French Wheeler, but not as good as some other, I had a bad accident (broken shoulder, now with some metal!!) with my small ninebot one E+... and I spent some time in order to understant why we face cut out or accidents. So, on the forums, I could recognize 4 kind of accidents : 1- Pilot did ignore alarm.... nothing to say.... too optimistic, 2- driving accident (bumps....), 3- Sudden cut off.... (looks like my accident, but I'm not sure it wasn't a technical failure), 4- Technical failure. Rare since construcors did improve the safety...or correct bugs (BMS for instance). For the point 3, I did some calculation, that shows that specification of constructors seems to be far too optimistic, and the speed alarm does not consider the wheight of the pilot... which has a huge impact. What I did consider is a common case of accident : you run on flat road, no alarm, straight... and you have a small slope (not big, couple of meters long!). So immedialtely, since you do not consider you have to slow dow, your Wheel has to give all power in order to maintain the speed during the slope. In this condition, considering a 10% slope (not big at all, it is a 6° angle road), what is the maximum speed you can run? I did consider air drag, which has a big influence over 30 km/h), the solpe that I consider as a safety margin, and the wheight of the pilot. The power was considered as constant whaterver the speed is (optimistic), and, since nobody know the duration of the peak's power, 0,5 second for this peak (which is only use for bumps in fact!). Yield of the Wheel in order to transform electrical energy to mechanical energy is estimated at 75% (tests on some gotways). What do we calculate show that with a 500 W, at 25 km/h, you're not save at all... except if you are a kid. On a gotway ACM our MS3, 45 km/h is not a realistic speed since air drag consume most of the power... What do you think? Conclusions : - Power, and slow speed is the key for safety... - Adapt speed limit cosidering your wheight, - If you want to keep the hight speed limit, go quiet, and in all case, use protections!!! Of course, this is only my caclulation, an you can disagree! EUC safety speed.xlsx
  3. so i know gotway maker of fast electric unicycles. are now in the making of a powerfull 2 wheel segway that is very similar (almost like a clone) of the ninebot minipro but some design changes, and different electronics, and gotway is known for being able to disable speed limits in the app and the motors also have a lot more toque and power! just look at this video! and this:
  4. Hi All, Moving in from the Firmware topic into its own topic for Open Sourced Hardware. Over the next little while I will move all the content from Firmware onto this post. I've been working on Reverse engineering the Gen2 boards as a starting point for development. Should have that done and posted today. We hope to be able to use the same Git to do both Hardware and Firmware advancements. I will post the important links as they come to this page. Lets keep the topic to Hardware. Although I have a Mechatroincs background my firmware skills are limited so we will definitely need some support from our Firmware buffs. Welcome to the topic. Mo
  5. And here I hear you shouting at me... when i answer "There are not any" Mini PLUS N4M340= Chinese market, branded MIJIA & Mini PLUS N4M350= World market branded SEGWAY Remember... XIAOMI invested in startup companies (Ninebot, Fimi etc...)with the help of, Sequoia Capital , is an American venture capital firm who invest in technolgy innovation., and have a Chinese branch, Sequoia Capital China who has invested into Ninebot. The EUC Ninebot One (2015) did not benefit from the Segway patents, it is from the Ninebot S2 that the Segway patents are used in the Ninebot technology. The Mini N3M240, N3M260, N3M320 have Segway technology, inspired by Ninebot's first personal transporter. ***** There are no two manufacturing plants for the Mini, one for the N4M340 and the other for the N4M350, the Mini Plus N4M340 & N4M350 are manufactured in the same factory. Whenever Ninebot releases a product, it immediately has FCC certification The Mini N3M240, which many believe is exclusively reserved for China, was in fact allowed, as soon as it was released in China, to be sold, marketed all over the world. The N3M240 was mentioned with N3M320 in FCC authorization. There is not a different firmware for the Chinese version or the World version There are only two elements that differ from the Chinese version: the charger and the packaging The charger American charger is in 2A (please look user manual, charger specs http://www.segway.com/media/2271/25521-00001_ab-miniplus-user-manual-en.pdf or european like Netherland http://nl-nl.segway.com/getmedia/1d7ef6e2-ff02-499e-84ae-0d5d5759690e/miniPLUS-UM-EN-FR-DU-IT-SP-2017-07-26.pdf.aspx?ext=.pdf) Chinese charger is in 1.5A That's all ! "And the speed!" You will tell me... No, no....no...no! About the speed Chinese Mini PLUS N4M340 : max speed 18kmh World Mini PLUS N4M350 : max speed 20kmh Please, you must understand: when Ninebot says "maximum speed", 20kmh, it's not the cruising speed. 20kmh is the peak reached at the maximum speed With my Chinese version of Mini PLUS N4M340, i could reach up to 24kmh / 21kmh ..., but only 3 seconds ! I checked with an alternative running application in bike mode Segway- Ninebot is playing with people's words and understanding ! A future buyer sees on the Segway Ninebot N4M350's specsheet: "maximum speed 20kmh", he thinks " I can ride at 20kmh", but it's not a cruising speed, you can ride in cruising speed 17kmh, 18kmh, 19kmh and you can reach peaks of speed beyond 20kmh, but only a few seconds before the tiltback helps you brake, lower your speed. A future buyer sees on the Mijia Ninebot N4M340's specsheet "maximum speed 18kmh", he thinks " f*** i can only ride at 18kmh" but in reality he can ride in cruising speed 17kmh/18km/h/19kmh, like the N4M350, and can reach peaks of speed beyond 20kmh too. Since the cruising speed decreases with the use of the battery (driving attitude, outside temperatures, land, user's weight) never Ninebot will be able to mention a cruising speed ! Ninebot writes "maximum speed 20kmh: it forces the Mini to roll slower, cheating on the cruising speed, lowering it by 1 or 2 km / h it's a fraud in France this style of commercial argument and distorting the speed limit is considered a fraud towards the consumer.
  6. I was updating my firmware on both my 16S and 18S today via the newest King Song App and had a nice surprise. Listed among the firmware changes was a line item stating they have now lowered the required speed unlock distance down from the previous 1,000km to a much more reasonable 200km. To my understanding this would be inline with the new 18L model that will be coming to market in the next few months. I was very pleased about this as I now have a bit over 700km on my 18S and am glad I don’t have to wait to unlock speed settings from 40 to 50 km/h. Not that I am a speed demon per say, but on nice smooth pavement I do get my beep warning that can get a little annoying at times, now I won’t be bumping up against the warning so much. I did verify through the new App after upgrading the firmware to version 1.04 that I no longer have the 40km/h speed restriction and was able to move the tilt back speed slider up to 50km/h as well as my number three speed warning now can be adjusted up from the previous limit of 40. I think this is a good move on King Song’s part as the 1,000 km requirement was excessive and may pose as a deterrent to some buyers.

    Ninebot One S1 Training Speed Limiter

    Hi All, Is there any way to skip the 1 KM speed limiter on the Ninebot One S1. I am an experienced rider and to go that slow is really annoying even if it is just 1 KM. -Steve

    How hard can I push my ACM?

    Just received my Used ACM . It’s the 820wh 67v version . V1 I believe but with the v2 (12 mosfet) board installed . It starts to show overspeed warning at 30kph on the app. I’ve turned off the 2nd alarm and set tilt back at 40kph . I’m just hesitant to actually push it that far for fear of failure . Thoughts ??
  9. Hi everyone, I was wondering if you guys know of any Android app that would let me track my rides storing GPS data that can be reviewed later on a map showing, not only max/avg speed, but speed at different points during the ride. For an example of what I mean, please take a look at the attached photo or this photo album containing screenshots of another app called Diablo Superbike. This app was designed for motorcycle riders and it tracks speed and lean-angle, and as you can see, there's a slider that you can drag to see your position at that time in the map as well as your speed and angle. Is there something similar but meant for EUC riders? I'm okay with an app that doesn't really connect to the EUC if it's able to record the path and speed (maybe even elevation?) during the ride, but it'd be great if it actually can connect to it and extract information like battery, temperature, pitch, roll, etc. during the trip. I've looked at WheelLog but it won't connect to to my InMotion V8. I also tried @palachzzz fork and while it connects, all readings are null (0 or empty). Either way, i don't think this app records what i want. I've also tried the Wheelinfo84v app, and while it also connects, it won't really display any info about my V8. It also doesn't seem to do what i want. I've tried looking at iOS apps like DarknessBot or Gyrometrics but I don't own an Apple device but from their screenshots, it seems to fall short of what I want. Any recommendations on alternatives? PS. @palachzzz any suggestions on getting your fork to work? Does your fork maintain compatibility with the other wheels? I could see myself taking your code as starting point to start my own app to do what I want if it will help other EUC owners than just V8'ers like me.
  10. Help!! My son got a Minilite for Christmas. Why does it lean back and try to stop when he reached 10mph? I realize that it tops out at 10 but why the sudden jerk as a safety feature? Can that be turned off?

    My Speed Reset to 28KMH Max KS16s! Help!

    I have been riding it about 3 months... I had reset it to go 35KPH.. Everything was great until yesterday when I noticed I got the "Please Decelerate" notice and tilt back... but going a lot slower than it should be at. I checked my speed settings on the app and it was set to 35 still, yet it was happening at about 28kph. I can't put in a new code on the speed limit decoding screen cuz once you do it once, you get the same screen as the speed limit setup. I tried uninstalling and reinstalling the app but it still wouldn't bring me to the proper screen to enter a code again.. I tried to install the new version of the app on my android phone from the website but it doesn't download.... so I installed the old app on my friends iPhone and finally thought I had it solved when I saw the proper speed limit decoding screen... I did it.. took it for a ride, and nope... still set to 28kph... I wonder if I need to reset the wheel to a factory default and how to do it. Does anyone know how to solve this? Help!!
  12. I tried my new King Song KS-18s 1640Wh and decided to make a video of its cruising speed. I'm 6.2 feet tall and 210 pounds. So far, it's very stable, reliable, fun etc. Link for the video is below:
  13. A buddy of mine has been riding his Ninebot Mini Pro daily for more than a year and he always complained about how slow and annoying because of the alarm and tiltback. Recently, he switched to EUC. He bought a BNIB Ninebot One E+ with NO modification at all. After learning and riding it for about a month later, out of curiosity I asked him whether he likes it or not, since I know that a Ninebot One E+ normally is not fast enough for regular cruising. But I was surprised when he didn't have any complain about its speed at all besides of the battery capacity, of course. Not even complained about any alarm / tiltback. At first, I didn't believe him. But when he showed me this... should I worry about him having a defective unit or happy for him for having the fastest Ninebot One E+ on earth?
  14. I went on a long ride yesterday to a beach far far away, on my way back I needed to cross to the opposite side of the road where there is no side walk but there is a bike lane, so after riding in the bike lane for a few minutes till I got to where the side walk started again, I decided to Take a peak at the wheel log app and saw that during that short stretch, I GOT UP TO 32 MPH!!. I was like whoa, that's the fastest I've ever gone on any of my wheels and the crazy thing is the ride was sooo smooth and comfortable it didn't feel like it at all, I guess another reason is I was riding so close to cars going 45+ MPH that it made me feel like I was going slower than I really was. The picture shows that I am at 48% battery life but I was actually at around 68% batt when I got up to 32 MPH, I took the screen shot a lot later
  15. Hello, I bought an Inmotion v5+ about two months ago. Now It has already 500km. I'm writing here because I'd like to increase the speed of my wheel but I don't know what is the procedure. Please, someone can help me? I heared that exist an apk to do that, but I would not be able to figure out how it works.. Thank you

    Fastwheel speed

    Hallo I have seen in the french site of fastwheel that maximum speed is setted at 22 kmh. I have 18 kmh speed limit on my wheel. Is there any way to change speed limit by ANDROID APP? Thanks
  17. Very simple question about the ninebot app. I can't seem to locate the option to change the units that the speed is being displayed in. I'd like to change it from Km/h to Mph. Is it hard coded to Km/h or am I just not seeing where to change it? Thanks,
  18. Hi mates, as promised I did some tests with the new firmware 1.25 on my KS16B, because there was the rumour (or info) that the maxspeed is now not lowered at 50% battery capacity, but at a lower capacity level (which would excite some folks including myself :-) ). Short answer: Yes, as an opposite to Ninebot (who worsened the firmware of my former MiniPro) Kingsong continuously enhanced the KS16 firmware, and now maxspeed is lowered around 20% battery capacity, not before. For me that's great, although it means there is a little bit shorter range, if I always drive at maxspeed (which I tend to do). What I also like is, that the maxspeed is not hard cutted from 30 to 25 km/h at a specific capacity level, but it goes down in a smooth reduction curve, starting at approximately 20% battery capacity. Long answer: The test was done on a nearly completely flat terrain, and my KS16B has alarm1 and alarm2 turned off, and alarm3 and tiltback are set to 30 km/h (the maximum possible). The screenshots were done when the wheel was continuously beeping, but still no strong tiltback, so not at an absolute peak speed, but at a maxspeed which can be kept for at least 5 seconds or more. This way I hope to have comparable results. The first screenshot at 63% capacity level is what you would always expect, also with firmware 1.23, the 30 km/h can be easily reached: Already more interesting at 34%, the set maxspeed can still be reached easily: 6 km and nearly 11 minutes later at 30% capacity, still no maxspeed reduction: Half a minute later I had to climb a small hill, still possible at full speed with 25% capacity: 3 minutes and 2 km later, at 21% the speed reduction is for the first time recognizable: But it's still higher than 25 km/h, the maxspeed seems to be reduced in a soft way, not with a hard cut: Now, only around 10%, the 25 km/h limit seems to be reached: And kept until the battery is nearly empty (from App point of view): Also interesting: In the Wheellog graphic it can be seen that the maxspeed is always the same (around 30 km/h) from begin on until approximately between 12h16 and 12h17, and from then on during the next 15 minutes it goes smoothly down from 30 to 25 km/h, no hard cut at a specific capacity: My conclusion: I like what i see regarding the maxspeed reduction, it is done in a great way in a responsible manner, from my point of view ! I also encountered a rather strong tiltback in the last quarter of my ride, when I was driving slightly downhill and did a very strong acceleration from nearly zero to above maxspeed. The tiltback was as strong as I never had it before on my KS16, so I was a little bit shocked, although it was no problem to decelerate. Regardless if this is also new with 1.25 or if it was already like that before, this is a good safety feature, because I was REALLY forced to decelerate by that ! To me the KS16B became an even better wheel by the firmware upgrade, although I already was very happy with it before !
  19. Hi all, After "only" 750 km on my Ninebot One E+ I decided to change the tire. It was not really necessary but I was feeling a kind of decrease of performance, increased tilt back in the last 100km. I was wondering if my battery pack was getting weaker but it was cheaper to try changing the tire first So I did, I replaced original one with this one https://onewheel.be/en/accessories/33-ninebot-one-buitenband-16-inch-1950-eur-ninebot.html It is actually not the original one but a thinner one (1.95 vs 2.125 inches). Because of that thinner size I feel it a bit harder to jump/mount on the EUC. But I'll deflate it a little bit and see if it makes it more stable. I think 45psi is too much on a thin tire, I'm not very heavy (less than 70kg). Now the nice part: it goes faster ! Yes a new tire makes a difference. I didn't measure my speed but I felt it faster, better acceleration and less tilt back when accelerating. So guys, if you feel your EUC is not as fast as you wish, if it has a quite high mileage, first consider changing the tire. Much cheaper than buying a faster one or changing battery Have fun !
  20. Have recently been bitten by the EUC bug and puchased a Ninebot One E+ couple of months ago. As I'm getting more confident, I am getting bored of the 20kph speed limit I'm getting from the Ninebot One E+ and was thinking if it is possible to swap the control board with this one: https://reseller.alibaba.com/product-detail/16-electric-unicycle-Controller-with-bluetooth_60288223259.html?spm=a2700.7724838.0.0.VsHfbJ Have seen other threads where other users have been swapping their control boards with the one from Microworks purchased from Alibaba. Also wondering if the motor for the ninebot one has to be changed to this: https://wholesaler.alibaba.com/product-detail/2015-New-Products-brushless-motor-16_60237639861.html?spm=a2700.7724838.0.0.XfG3kt What do you guys think? Any other peripherals that have to be changed as well like hall sensor connectors or the like? Or if this hack is even possible? Appreciate your comments. Cheers

    Frankensteining in your C+ into a E+

    Well pretty sure my C+ has a 500w motor, kind of says it on the wheel, noticed it while messing with the controller, Controller it seems is ver 1.3 the same as the E+. Thinking of getting a 320WH battery for the C+ which I like best go figure rides better, for more range, and carry the smaller battery extended trips with the C+ or E+. Now I know I will get the E+ range with the new battery, just wondering if I will get the speed and power of the E+?

    Airweel Q1 in real conditions : review

    Hi all. I'm a new user in the world of the unicycle. I bought last month an Airwheel Q1 for 110 USD ! after 10 minutes I was already able to use it and after one day was totaly confident at start. I use it every day to go to work, it's very stable and easy to drive. Very convenient to make interchange in public transports. I juste think it's a bit too slow (my weight is 93 kg...) The cruise spead is between 11 and 12 km;h and autonomy around 12 km (i will update later this post with a distance test.. I have recorded today a trip with my gps watch (10km). You can find attached the detail of the trip : instant speed, altitude ... Airwheel Q1 real conditions test.xls

    Maximum speed

    Probably the motor of the IPS Lhotz is powerful enough to go a lot faster than 20 km/h. The 'software' maximum speed is 16 km/h, after that the machine will protest and eventually even shut down if pressed beyond 20 km/h. I tested that and it hurt. Is there a tweak or hack or special app with which I can set the maximum speed to 25 km/h ?
  24. Hi all, I'm seriously thinking about getting a ninebot one e+ or maybe s2 when I can get some proper reviews and specs for it. So my question that I hope some of you can help me out with is speed vs rider weight. E+ is supposed to go somewhere between 18 and 22 KM/H so what should I expect if I'm around 90kg /200 pounds? The second questions is how 20 km/h feels... I mean if I want to use it for commuting 20 km/h is needed but can I actually (after some training of cause) use that speed without getting a close to death experience each morning? It's really hard to tell when you're not able to try one out, as a matter of fact I have never even seen one live so I hope someone can help me out here Thanks /JB

    IPS Zero speed warning

    Hi! Was curious about during what speed the speed warning started to beep and opened up Waze during the ride. Waze tells around 23-24km/h when the beep starts. This wheel is told to have a Max speed of 30 but the sound make me not want to try to go that fast. Anyone that have tried?
