    Since i did not find the original thread ( imho the posts were just "hidden" in some other thread..?) from the first dynamometer results published at http://electrotransport.ru/ (linked here by @Raptor) here a new thread with some new results: http://electrotransport.ru/ussr/index.php?msg=973382 The full tests including description of the measurements are published at http://airwheel.ru/test-monokoles-na-dinostende/ (also with a comment that the dynamometer is made for motorcycles with much more HP and so the results are not really exact absolute numbers but a nice comparison between the different wheels)! Also i did not see a comment about the "measurement probs" he mentioned in his first test: He could not start the dynamometer with full power from the wheels, because some fuses burnt... So he had to accelerate it "slowly" up to ~10-15km/h before he could apply full thrust. So some/most of the charts show some quite low powers for low speeds. Mabye he found a way to overcome this prob or it is still seen (imho in the charts for the high power 18 inch wheels?) Some interesting first points: - the IPS Zero shows some strange behaviour: The power output halves for speeds about 16 km/h! Also with a max power of 1.1kW it is one of the weakest of the tested models... - bigger batteries (capacity) give more power! ( how to translate "Na no na ned" to english? ) - nicely to be seen in the comparison between the KS16 340Wh and 840Wh model. - The MSuper V3 1600Wh 84V started a new era: it shows a max power of 4.7kW! - a nice statement regarding Airwheel (not included in the summary charts): "Test shatters all hope that this device can drive" -Test of ACM with custom LiFePo4 batteries: ~30% power increase! - Test of Inmotion V8 with Samsung INR18650-30Q 3000mAh cells: ~20% power increase, but the internal fuse was not able to withstand the increased current... It would be great to see the results from @EUC Extreme's custom Gotway in comparison to a standard factory version! A Quick overview of the results (links to the pics of his homepage): 14 inch wheels: 14 inch with more "power": 16 inch wheels: 18 inch wheels:

    You do owe them a conversation if you want to do your bit for EUC community relations. If the public see early adopters of this 'new' technology as being aloof, inconsiderate, or even outright rude, then it is so much easier for them to hate us, and it gives them ammunition they can later deploy at council meetings and the like... I am not even slightly a 'social' person, but I will always stop to talk to someone taking an interest in my wheels, and I do my very best to make them leave the conversation feeling like they've had a very polite and courteous (and in my case tediously technically information-rich) exchange with someone doing a new and exciting thing, and not only that, but doing it well, and with maximum consideration for pedestrians. I want people to think about me, and us, like that. Having been doing that for several years now, I have a whole town full of people that know me and my wheel, and wave and smile as I go past. All from a little bit of basic politeness... Of all the people I have ever stopped and talked to about EUCs over the years the feedback has been overwhelmingly positive, and those people leave that conversation very much on my side, and certainly not seeking to prevent me doing it more. This is especially important in places where the legality of the EUC is still questionable - we need the people on our side (or at least not actively against us) if this is ever going to be mainstream and legal like it should be...

    @hobby16 thanks for the information provided. 1. It's not the charger problem, when I tested the output current was around 1.9A. 2. Following your instruction, I checked all the cells and found one cell is dead, the rest shows between 3.7 to 3.9V. I asked my friend to find and replace the dead cell, after that we still couldn't charge the battery. And we found out another issue with the board of the battery, there are 2 dead diodes. Then we managed to change them, fortunately we can recharge the battery and my unit starts working again. @smallexisI will keep your information and guidance for the future in case we need to change a BMS, however hopefully it won't happen. Thanks you guys a lot for helping me. I am happy to have my 9B1 back again

    Returning Boomerang Step-off, Step-on Trick ***You should ensure that you already have good EUC balance and control before attempting this type of trick.*** Before learning this trick you should master the simple Step-off, Step-back-on Trick and it's variations. This trick needs a large flat surface - an empty basketball court is perfect. Use of appropriate safety gear is recommended and you may also want to consider protection for your EUC, as it will most likely get scraped a few times during the learning process. Start by going slowly and practice dismounting the wheel so that it's continuing path is a uniform curve - this requires less speed than if you want the wheel to just run in a straight line. If the surface is flat and uniform it should be possible to make the wheel return to it's launch spot (or very close to) where you will need to jump back on to the approaching wheel. There are various options for getting back on the wheel - you can stop the wheel dead or keep rolling backwards. Alternatively you can turn around letting the wheel come through your legs before jumping back on.

    It could be set for the phone, but on your Apple Watch, set it to "Mirror my iPhone". That way, if you are using the watch, it would do the same as the phone.

    The BMX bike was an elaboration on the 20" kids bike, the mountain bike evolved from a regular full size bike mixed with BMX, the Skateboard was a roller skate cut in half and nailed to a 2x4 before we did any tricks at all, the drift car and NASCAR evolved from the model T driven by moonshiners that decided to race each other, base jumpers jumped out of planes first, parachutes were for safety, extreme frisbee Golf evolved from a toy, rock climbers did it out of necessity first, surfing was a 14 foot longboard made out of balsa wood before it shrunk to a 6 ft fiberglass board, the roller skate as we know it was a toy with metal wheels, the wind surfer was a sail on a surf board before it caught air off a wave, the 4x4 was a utility jeep first, stunt planes evolved from biplanes that were just meant to fly….etc...etc. The regular unicycle was fun and challenging and part of the circus half the time....then....the extreme street and off road came along. They broke unicycles (pedals, seats and cranks etc) almost every time they went out....until.....somebody made one that could handle the abuse. Now there are these riders all over the world and many companies to supply them with the durable tools they need to make it happen. This is what is up....for me....and anyone who wants to join me! @Jonathan Tolhurst @Toby Stevens @Hirsute @Chris West It's on brothers!

    Hi folks, I am just back from a test ride... With a new headlight ! I managed to fix two bike LED headlights, each powered by 3 AAA batteries. And it is great ! I can see street traffic signs reflecting my lights 100m ahead ! Cheers

    I've had a few instances where I got something back said to me. One was from an older guy on one of those super light bicycles and he gave me a thumbs down and said, "No motor vehicles on the bike path, booo!" I was funny though he was going over 25mph to get away from me after he said that and then i was still behind him. So, I just decided to let it go and let him have the win. Look if people are going to judge us then they will. You don't have to change how you act to meet their demands. With that being said, I still stop when people ask me about it. I talk to them because I like the look they have on their faces, the look that says,'How is it possible for humans to do this?' I want to be the one that tells them anything is possible as long as you can dream.

    When stop and talk you will be amazed at how many people show you how rude selfish and inconsiderate they are. The attitudes you will get will reassure you of the wisdom of not stopping in the first place. Seriously I ride for my own enjoyment. I dont owe anybody a conversation. That said the people worth talking to will make it apparent. Some people are cool as hell and say intelligent and funny things. Bless those few

    As a glass is half full kind of guy, I'd say just be happy that they aren't asking you to help teach them how to ride. Maybe they might stare less if you were naked too? Nude EUC riding... well except for the helmet, elbow and knee pads, and gloves might be a new sport you could introduce to the country!

    Agree, It needs a table with speeds, battery calibration, etc. Now added a feature to AppleWatch. I changed from the elaborate trick I used and a double tap in the center field sounds the horn in Kingsong!!!! Hope to put the calibrations for next version. I wanted to be able to manage a library of your wheels (identified by the Bluetooth id, for example) so you may configure speed alerts and other information. Temperature is read from the wheel but has strange number for calibration so it may be this. Need to have a Gotway some time to test it (and a termometer) :). Anyway yhanks for pointing it. will work it soon.

    As an owner of both wheels, I can confirm that the ips zero motor is significantly less powerful than the v5f+. Although the zero can go up to 29 kph (tested), the conditions need to be ideal (slightly downhill and flat smooth surface). Above 20 kph, you need to be very vigilant of bumps, or you're running. The v5f+ can go near it's top speed of 25 kph, even on bumpy roads. The only advantages the ips zero has is that it is lighter, more compact and cheaper. The v5f+ wins in every other category.

    You also can try turning your wheel around. If its then tilted backwards its a calibration issue. If its still tilted forward its some fault or mental ?

    I would check to see if the motherboard is getting wet. Unless you're wearing German ww2 hob nailed boots, you would know if your feet were too far forward on a ks14; those pedals are so short, the balls of your feet would be swinging out there in the breeze, and you'd feel it, I do. Or do you have tiny feet? Don't laugh, I knew a guy who was 6'2" and had size 8 feet. ( for you euro types, someone that tall would be size 10.5 and bigger.) When I replaced my beeper (ks14c) (see post) I observed that the gasket for the side panels is rather thin, and didn't like to stay in its grove. The mother board is RIGHT THERE under the top edge of the side panels. As I said in that post, I wouldn't ride in the rain without putting some tape over that top edge. Ride in the rain! you must be mad man! Oh, commuting, I see. you might want to take your side panels off and have a look for traces of moisture. If so, my post shows an easy, non-destructive way of doing it. Disclaimer, your risk once you go in there, high currents, high voltage, etc. can't discount @Cloud theory about slipping, but you were there and we weren't. @nomad HEAVY RAIN indeed! Maybe it rains heavy water (H2O2 is it?) in New Jersey as for level calibration on ks14c, I stated in my first gremlin thread that I had discovered the correct way. I was surprised no one asked how, then. But since you ask now, I'll create a thread in the Mods, repairs, DIY ( oh look another TLA) section, or what ever it's called. I'll call it something catchy like. KS14c, Level Calibration, the correct way.

    Dont do that. One should be able to jump off the wheel at any time, when needed

    Simple - pavement was wet, tyre slipped and the wheel couldnt keep you upright. Yu must have accelerated a bit right before this happened, or went over pavement too smooth/ slippery. One broken screw on the casing is fine, one of mine is broken also in the same location.

    @Dima Ninebot's people won't give you any relevant answer I'm afraid. They'll just tell you to buy stuffs. Your problem can have several causes, more info is needed to know which is the real cause : - Charger problem. It can powers up the wheel but still be faulty. Can you check it by the test above, yes, no ? - battery problem. Saying the "voltage is normal" means nothing unfortunately. The voltage of all the cells must be the same and in the range 3.3V to 4.2V per cell. What is the voltage of each cell and the total number? Without numbers, hard to tell. - BMS problem. There is a simple solution by shorting the BMS' charge mosfet (see schematics in my thread on BMS http://hobby16.neowp.fr/2015/07/21/bms-how-to-make-your-wheel-safer/ ) but the 2 causes above must be ruled out first.

    I have added INMOTION to my list of wheels compatibles with the Charge Doctor. A summary of the specifics of Inmotion wheels, especially concerning fast-charging, is on my blog. Cut & paste of the blog's thread below: INMOTION unicycles have 20S batteries (nominal voltage 72V, charger voltage 84V) instead of the 16S classic topology on most other electric unicycles. Models V3 and V5 use the “square Lenovo” connector and model V8 uses the GX12-3 pin connector (same connector and same wiring as hoverboards). Charge Doctors for IMMOTION wheels are now available, in single-input or double-input versions. Warning, IMMOTION battery packs have less capacity than Gotways or King Song’s. So when using the CD-double-input, check that your setup does not charge at more than 1C (see article on “charge currents“). The CD’s usefullness is not only in allowing fast charging, it is mostly in the autocut function to automatically stop charging at 80% or 90% to preserve the the battery and considerably extend its mileage. INMOTION (72V nominal/ 84V charger) Connector Wh Ah Charge* at 1.5A (1 charger) Charge* at 3A (2 chargers in //) V3 Lenovo 144 2 0.7C 1.5C to be avoided!!! V5 Lenovo 288 4 0.4C 0.7C V5+ Lenovo 460 6.4 0.2C 0.4C V8 GX12-3 460 6.4 0.2C 0.4C *For a 2Ah battery, 1C charge corresponds to charging at 2A. On LiIon batteries, a <0.5C charge is considered a soft charge, a >1C charge is not recommended. Charge Doctor double input with Lenovo connectors, for INMOTION V3 & V5 Charge Doctor single input with GX12-3 connector, for INMOTION V8

    Most of the time I answer "It's an electric unicycle!" while continuing to ride by without slowing down. Occasionally, depending on the situation and how the person is acting, sometimes I do stop and have a conversation. I have met some people who were very fascinated and really wanted to know more about EUCs. I also use zlymex's method of giving a friendly wave while smiling (sometimes I say "Hi"), which makes it seem like I did not understand what the person said.

    we are thinking of selling 40A for super users. But we dont have suitable motor to match 40A. Only 500W motor is not enough for its performance.

    Actually I switched on my kingsong KS18A and opened the app only on the watch, did a force touch and tapped on start. The wheel was shortly (after 2 second) beeping and it's showing me live data on the watch immediately, without having the app open on the iPhone! Thats quite comfortably! ???

    So I did calibrate with a -2* lean. I even made a video. It appears that before the calibration, it was leaning forward at 1*. I'm not sure when that started, it'slost in undocumented history. Not ridden it yet, I'm on the eighth floor and any unusual behaviour might result in the MOAFP. Mother of all face plants. Not to be confused with MOAB, but ironically, slightly similar effect.

    It should be noted that the unit shown at Alibaba does not have the 12 mosfets. This wheel really intrigues me, but will we be able to buy it? And that shipping cost is kind of a deal killer.

    Final word all: I met with a friend who had ridden it before and he told me it's all in my head; I guess the PTSD from the crash is getting me worried. Some vicious grip tape arrived in the mail today, so tomorrow I'll add it to the pedals and hopefully feel safer!

    Figures. Thanks. I'll look it up. I was browsing his many mods on a photo sharing site he linked to. I probable saw it, becauseut I can't remember ship these days (CRS) . He is THE person who knows how to built an EUC the right way. I'll go,look at his mod. Photos again. In the mean time it's no more jumping off benches for me, no sir. Gotta make that axle last, even if it is made out of metallic cheese.

    @John Eucist I looked at your link. You maybe interested to know that all those words come from the Greek language. English is a Germanic language with Romance language bits and pieces thrown in, and a lot of it is based on Latin and Greek, and another older language that my nephew schooled me on one day, but I forget now, I've slept since then. watch out for eugenics though, in spite of "eu words" being a word category of pleasantness, In the first half of the last century, this and other pseudo (also a Greek word) sciences were used to reinforce the theory of racial superiority, and by default, inferiority, which resulted in millions of deaths. But the mad men behind that black chapter of human history are all gone now.

    I can't comment on the technics of the V5F(+) and if it's top-notch or not since it's my first and only EUC...so I can't compare. But I haven't had any sudden cut-outs, strange sounds or unexpected behaviour so far. It does what it's built for and it's a lot of fun riding the wheel Reading about the problems of other brands it makes me feel good to have chosen inmotion, that's for sure

    I bet the problem is the mode since Ride is the 'soft' setting. Use Play mode and your problem will go away. Good luck. P.s. The soft mode setting is probably not a problem until you push the speed towards max, which it sounds like you do. I bet if you ride at 10 mph the forward tilt is much less noticeable. I ride all my wheels at the 'hard' setting.

    Maybe you got some moist/rain on the motherboard which caused some malfunction? I had once a replacement motherboard for my KS16 which unmotivated tilted forward while riding. Especially while turning - there it tilted forward until cut-off. I don't know what the exact reason was, just that the motherboard was faulty and with a new replacement board everything was ok again... Is yours still tilting forward, or was it just at this ride while raining?

    What do you mean by the sentence in bold ? The problem comes more probably from the charger. Connect the charger to a hair dryer (dumb load) then measure the current. If must be 2A, if not, your charger has a problem.

    Build quality could for sure be better but to seriously improve it will probably drive up cost too much for these small companies... I think we won't see any impressive build quality until EUCs get into mainstream, the risk is high to try producing anything too expensive in small quantities.. For mainstream it has to become a common and reliable commuter vehicle like a bicycle to build a large user base, but now there's issues even with cheap pedals mounting methods.. The focus now is still on basic functionality such as better speed, range or portability while construction takes the back seat like a prototype. So you have to buy a new wheel every year if you 'abuse' it.. EUCs are still seen as toys and are relatively expensive because there's no mass production and import taxes plus shipping doubles your price.. I can see buying a lot of wheels would add up over the years... I think for more trick/extreme riders eventually even a Tesla model 3 or something is not a far stretch economically if you split the cost for two people for example, maybe boring but for the masses a car is also easier, more versatile and comfortable that can add a lot of value.. Most fun hobbies and sports do cost you, but if you can afford this it's definitely worth it after all. So I wouldn't hold my breath just get what you can and enjoy

    @Jonathan Tolhurst sounds like an awesome trick involving a great deal of practice, bumps and bruises to both you and your NB. You should represent NB in Europe and get spare parts for free as I am sure you change parts often. Are there any universities in the UK that have motion gait labs with EMG? We have used this system to evaluate patients with musculoskeletal issues to determine their gait patterns and what muscles are firing at different percentages of their gait cycle. Some universities have motion lab grad students that are always looking for challenges. You and @Hirsutemight check with universities in your country and ask if they are interested in setting up a motion lab session as you perform tricks. It would certainly add a new element to the EUC sport.
