  1. Dear All, As a new rider, my skill and comfort has improved. However I am experiencing a few consistent issues which are not resolving naturally. Background: I recently started riding (a few months ago) upon purchase of my first wheel. Wheel: Nikola 100v Molicel pack and honeycomb pedals Ride Facility/Level: "Comfortable beginner" -- My primary riding is city riding in Washington DC (sidewalks, bike lanes, etc). Typically I ride about 10-12mph. I am comfortable riding very slowly without twisting and easily staying behind slow walking pedestrians. Problem / Issue: I've found that, at my current level I am encountering 2 primary difficulties: Slow tight turns without over-leaning wheel or without acceleration / forward body lean. (Problem less of an issue on other wheels (T4)) wheel contact point with the leg (forward - aft) makes a huge amount of difference in the ability to make such turns Use of power pads --- helpful for other things (see below) restricts this ability I recently purchased a T4 for my spouse and am able, with much less input, to turn tighter and slower. I thought this was due to pedal height and that I was still over-leaning (but unable to notice it). However in watching a video, when riding the T4 the wheel is not leaning heavily to one side and simply feels more responsive. Wobbles consistently at the 14mph speed This has been the case consistently over the last month and not changed despite skill level improvement. This is consistent regardless of bumpy vs smooth terrain or slight grade uphill or downhill. In experimenting with power pads I've found fewer wobbles However, I find my maneuverability drops significantly. Here, maneuverability is especially restricted if when turning the inside/straightened/low leg is restricted by contact with back of pad Questions: Re Maneuverability: Technique: Is there a particular exercise that helps in the ability to make smooth tight turns at low speeds without leaning the wheel too far or resorting to the jerky heaving-hips turn? Contact Points: Can you all comment on the forward-back, and vertical contact point effect on wheel maneuverability? For example: higher vs lower leg contact point higher vs lower pad placement forward-aft leg contact point inward vs outward foot position (close to wheel body vs wider stance) If the T4 is easier to turn due to higher center of gravity (?) , is there a stance/position/setup to assist me in compensating for this by adjusting my ride on the Nikola (or any wheel with lower COG? Can anyone comment on the physics and tradeoffs of pedal angle calibration? I.e. if you use a non 0 angle, is there an established effect (outside of personal comfort). Re Wobbles: Given that my oscillations are consistently occurring at the same speed, and regardless of day, comfort, terrain smoothness / grade (bumps and smooth), are there any steps to diagnose my riding so as to start incrementally increasing speed safely? Since this is a multipart question feel free to respond to a single part ( in that case please reference the question to which you are responding. For example "Question 1.2 " Many Many Thanks, B
  2. 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
  3. 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,
  4. Hi All, I am a new rider and loving it so far. I am wondering what speed alarms do you guys set within the application which take into account battery drainage? I am a heavy guy (116kg) so very interested to hear from others who may be packing the lbs like myself
  5. I've been looking around and only seem to find good solid info on the 84v version. I have the 67v Mten3 and want to know if anybody out there has found a reliable top speed. I'm 150 pounds riding and usually get around 18mph before it starts beeping like crazy, but the wheel feels like it has more to give. Has anybody experienced a "high speed" related cutoff on this wheel? Lastly does anybody have recommended app settings for their 67v version? The gotway app as of this post doesn't work AT ALL, and frankly trying to adjust alarms on EUC world and Wheel log apps don't seem to do anything at all for the 18mph beeps. Thanks in advance for any help or insight!
  6. 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.
  7. Hey Guys, I have a couple of rookie questions for you regarding the settings on my KS 16x. So for speed settings I have disabled alarm 1 and 2, alarm 3 I have set to 39kph and kickback at 40kph. The top speed of the KS16x is 50kph in ideal situation so I put margin as I don't want cutout so I my face doesn't eat the floor. (too old for that) My question is with King Song as a vendor, are those values set in stone or does it slowly ramp back the settings based on your battery percentage? So in my case if I set kickback to 40kph at 20% power does it kickback at (I dunno) 30kph...? I'm just trying to understand are those hard rules or is there logic in the board that ramps things back depending on the available power? I know Gotways by design allow you to get yourself in trouble and leave it to the user to be smart enough to not get themselves hurt. I guess while I am at it, can other KS16x owners share their settings? I am curious how other people have it configured. Thanks for the help. Cheers, Neil
  8. I recently purchased a King Song 18XL. I'm using the Darknessbot app since the King Song app was pulled from the app store, and I have a little over 30 miles on my wheel. I'm not completely understanding how the three speed alarms work in Darknessbot. I had all three set to 25 mph, but one explanation from another rider indicated to me that each alarm had a specific function attached to it. For example alarms 1 and 2 are beeps and alarm 3 is tilt back. I take that to mean that if I disable alarm 1 I will only get one beep alarm before I get tilt back. If I disable both alarms 1 and 2, then I will only get tilt back. So in order for these alarms to work properly, I must set them in successively increasing limits. Am I understanding the speed alarms correctly?
  9. So back in the day most everyone of us rode the Ninebot One E+. No matter how hard I pushed the device at it's top speed despite the tilt back I was never able to get it to cut out. I did however manage to overlean the device by accelerating too hard. Was it my lack of skill back then to push my E+ beyond the max speed or is it that modern wheels don't have the same protection for riders to not reach cut out speed? Why can't the wheel just not permit the rider to go beyond a certain speed?
  10. I am planning a 100 mile Dawn-to-Dusk ride this summer with a KS18L (not XL sob..sob). I will spend 6 hours charging. That means I must execute the right ratio of speed to time, or I won't make it. It will be very hard, early in the ride, with adrenaline flowing, to ride at an even, conservative pace. We shall see. I am sure there are others interested in doing extreme long distance rides. To be called a Extreme Long Distance ride (ELDR) for purposes of this thread, the ride has to be a minimum of 80 km continuous. You can stop to charge, eat, relax, but you must complete the ride as part of one riding session. If one is doing a multiple day ride, one can slip below 80 km on a given day, but the average for the whole ride must equal 80 km/day. The challenges for my ride is my riding weight of 109 kg, and that there are NO places to get partial/quick charges except at designated locations at the end of each leg and those will be full charges from 10% or so to 100%., taking a minimum of 3 hours with 5 amp charger. I am considering using a 5 amp charger and the regular 1.5 amp charger for a total of 6.5 amp charging. I think that would still be safe .. ? Anyone can ride fast .. who can ride long?
  11. 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
  12. We live in an area where there are lots of steep climbs. They are not really steep, but they have given me problems with unexpected push-back from day 1 with the MiniPRO. There is little data available on exactly how much power the MiniPRO motors can deliver, and how this translates into speed on either flat or sloping surfaces. The best source of information was shown to me by JoJo, it is a blog about the MiniPRO development cycle at Ninebot: http://bbs.ninebot.cn/forum.php?mod=viewthread&tid=4100 Google translate produces this for a key section of the blog: "We have done a lot of power test experiments. The results show that when the weight of 100kg people climbs 15 degrees at 5-6kmh, the power demand of the whole vehicle will reach 400 watts or more. If the slope is slightly accelerated, the power will rise to 800 watts. The tester weighing 120kg may reach 500 watts when driving at 20kmh, and the output power of the car may reach 1000 watts to 1200 watts when it accelerates to 30kmh." So, I read that as saying a 120kg person riding on flat ground will need 500W of motor power to reach 20Km/h, and 1000W-1200W to reach 30Km/h. The continuous limit of the motors is "350w / short time 1050W, and the maximum torque of a single motor is .. more than 35Nm." So the firmware has to decide when to start pushback whenever the continuous output power being used is greater than 700W, or else the motors will overheat,and likely the battery pack too. Here is the 19 degrees street that the MiniPRO design team used as their reference for the "World's Steepest Street" But they eventually decided on planning for a 15 degree slope, less steep than this one. They planned "100kg people climbs 15 degrees at 5-6kmh, the power demand of the whole vehicle will reach 400 watts or more. If the slope is slightly accelerated, the power will rise to 800 watts." This represents the totality of the engineering specifications I have been able to find about the MiniPRO When I measure myself, a new N3M320 MiniPRO which has not yet done 50Km starts to push-back at around 9Km/h on the steepest steady hill I have around here, which is 6.5 degrees. I weigh 94Kg (in riding boots). I see no difference between firmwares 1.1.7 and 1.1.9 except that 1.1.9 has the gentlest pushback cycle (it beeps a warning before making you jump off ). With 1.4.1 it is tough to even reach 9Km/h because it is continually adjusting the push-back point. An N3M260 which has long-ago reached its 50Km transition can reach 11-12 Km/h (with v1.1.9 FW) before beeping and starting kickback. The max speed is the same whether I am using the smaller 243Wh or the full 310Wh battery. So there clearly is a safety margin which the firmware holds in reserve to try and preserve vehicle integrity. Yet how the firmware implements this push-back reserve is (IMO) flawed, as it also seems to limit the ability of the MiniPRO to handle potholes and pebbles until the 50Km mark is reached. I will be watching very carefully as my new N3M320 reaches that target, and then do a complete reassessment of the vehicle's hill-climbing ability... Finally, I note that the older N3M260 had the 90/65-6.5 knobbly off-road tyres fitted, running at 15psi, while the new N3M320 has slightly smaller 'off-road' tyres, which should have given it an edge in torque, but didn't. Only when I get to 50Km will I be able to decide how the firmware handles safety reserves when larger tyres are fitted - there is a possibility that the slope climbing speed limit is set by a firmware algorithm, and not by the motor power exceeding 700W. Please share any data and experiences you have had negotiating slopes with the MiniPRO.
  13. Am on a nice long Saturday morning ride with my beloved monster, stopped to take a break pulled out my phone and I saw this, it has to be a forum record if not a world record, anyone know the number to Guinness?... no not the beverage hahaha
  14. 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
  15. 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:
  16. 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.
  17. 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
  18. 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 ??
