    Over the past 2 weeks I have only used my Msuper to commute with the round trip from home to work is around 30 kms. Today I felt sorry for my Ninebot One E+ it has been sitting in my garage collecting dust for 2 weeks. So I decided to ride it to work, oh boy was it a long and painful trip. Without realising I have reached tilt back so easily and the maximum speed I can get is around 22kph. At this speed it felt like I was walking, I had to think the whole trip to slow down. I could have sworn that the Ninebot didn't feel this slow before. I am going to take public transport home and ride the last bit, don't think I will be able to ride home it was stressing me out. What a difference cruising at 35kph makes not even mentioning how uncomfortable it was also. Poor Ninebot is going to retire for good now.

    It wasn't to hard I took my time, the hardest part was the head lights, I basically pressed it against the unicycle and use a pen to mark the cut out but slightly smaller than the actual cutout so the pen mark won't show then I make the necessary adjustments, no tape measurer. Here's a pic of my 1600 feel free to copy which ever style you like, oh and also get some clear 3m tape because the tape that they provide with the foam doesn't work to well in the matte material,10mm will be fine

    Funny...the DHL delivery truck arrives at my house at 10pm last night! What company delivers packages that late at night? I had rerouted the new motor for delivery to my work address since I would not be home during normal delivery times and I needed to sign for it. For some reason my home address was still on the guy's computer. So this poor guy drives up my dark driveway after working a 12 hour shift and rummages though 30 packages in the back of his truck only to find out there is no wheel on board.. I had a feeling but I helped the guy anyway. Then I find out the guy still has to deliver the remaining packages in his truck before going home. He was cussing out DHL all the way saying he gets sick worrying about what might happen when deliverying packages to people's homes this late at night. Last week he was cornered by 2 German Shepards. I hope he made it home safely!

    After riding the new MSuper a couple of weeks ago, side-by-side with my ACM, I can say that the MSuper's shell is similar to the ACM, but the ACM still has a more rubberized texture. They are not the same materials. But it does appear to be an improvement over the original MSuper. Having now put over 800 miles on my original MSuper V3 820wh wheel, and dropped quite a few times, I can say that the MSuper is not a fragile wheel. I don't feel like I have to baby it at all. Of course you can always have a freak fall where it spins out of control and hits in just the wrong place, causing serious damage. The same could probably be said about most wheels. Being a wheel that you're going to learn on, I think it's a good idea to add padding on the various corners. When I learned on my ACM I went to Home Depot and bought a 8' length of rubber copper pipe insulation (not the foam type). About $5. Then buy a roll of 3M Low Residue Duct Tape (leaves no residue if removed within 6 months). It's an inexpensive alternative to Gaffers Tape. Use that to attach the rubber to the wheel. The tape is also available at Home Depot.

    Dear @rayna903, please correct me where I'm wrong. My sources for this post are https://www.facebook.com/1593003297614828/videos/1875867519328403 and http://www.iamips.com/product/showproduct.php?lang=cn&id=31. Apparently, IPS is about to release a new EUC called "i5", available in two models using either the common 18650 or the slightly larger 20700 batteries. It seems to be a "last mile" solution for lighter users with 350W rated /1000W max. motor power and just one pack of batteries (16S1P). While that sounds like very ordinary entry level, the shell design is uniquely flat and apparently made from some magnesium-alloy, which takes all the structural forces while keeping the total weight below 8Kg. Batteries appear to be Panasonic 20700B with 4250mAh. While it is certainly not a performance beast in any dimension, I think it's quite an interesting approach for the light & casual user. I am very curious for feedback from everyday users on how the new shell holds up and whether those 20700B batteries might be an option for higher performance wheels, too.

    Hello there! I am new to this forum and I am also new to King Song. But after having read a lot of the threads here, I decided that the KS16S is probably the best wheel for me - maybe not as fast as a Gotway ACM but safer and with more of a quality oriented design thinking. I ordered it directly from Diana@szkingsong.com last week and today she gave me the UPS tracking number for it. Diana has been very helpful and service minded, so I am now super excited to actually try out the wheel when it arrives in 10 days or so...! Although I am still very much an amateur, this will be my third wheel. I started on an Orb Wheel X2 that is now broken after having suffered too many bruises, but then went on to an IPS Zero and a Xima Lhotz. Will let you know what I think of the KS16S when it gets here!

    My first post to this forum About a year ago I read an article about Finnish guy riding a EUC in the middle of the snow in Rovaniemi. I decided that some day I want to have one too. With a lot of reading this forum and watching Ians reviews I ordered Ninebot C+ about a month ago. I watched all kinds of tutorials how to learn to ride but at the end I did it in my way. I rolled few hours in two days inside house from the corner of the living room to a kitchen taking support from everything i could on the way. Third day I encouraged myself out and it started to go very well! I was supposed to rode only in the neighborhood but I rode many kilometers around the area with a big smile on my face. Fifth day I was at work with my Ninebot. It was funny leaving to home while there was 20 or so people watching outside - no pressure to keep your balance ECU's are not that typical here in Finland. At way home I had my first almost face plant. I accelerated to a bridge where there is an increasing incline. It didn't seems so steep when riding. Suddenly my bot was beebing once and trow me away. I had my gear on (motorcycling is my other hobby) and I was luckily able to run an keep up (jogging is the other one). The bot was hurt more than I did with a nice scratches on it. I rode home and didn't touch it for few days. Yesterday rode another demanding route. Now when I went hills slower there where no problems. I thinks that situation before was just too tight with 450W motor and my 100 kg (220 lbs) weight. I was accelerating too fast in a demanding place. I think that for persons my weight there are better choices than Ninebot but when going easy in hills it's a lot fun too. Yesterday I got about 15 km with 220Wh battery going as fast as i could almost all the time. Last 2 km was in "limp mode" with a battery less than 20%. Uni-cycling is so much fun! After my crash I started to look my next wheel with more power. But that'a a another topic.

    Okay, the deed is done! Talked to Jason a few minutes ago and paid off the remainder. He says the latest shipment of wheels is preparing to head across the ocean and he expects them to come in right about on schedule in the first week of June. Add a few days from California to Oregon and I should have my new MSuper. I will spend the meantime squirming in anticipation.

    The speed is relative, with a cart like this, in downhill you can be faster than a Ferrari Testarossa

    In a way, I think it's scary how safe people make it sound. Riders like Duf and Marty regularly talk about hitting pretty high speeds on their Monsters and MSupers and sometimes not even noticing. I find the same thing happens with cars. When you can really feel the road, like in a small economy car, you know how fast you're going and it's easy to stay at a safe speed. In a luxury boat, you float along and have no idea you might be well into the danger zone ...

    The shell, assuming the rubberized version sold now is like the ACM's, is virtually bombproof (the screws are the weak point). These wheels are much sturdier than you think. If you want to use a leash, obviously fix it to the real handle (not the retractable one). You need to worry about scratches mostly, the wheel won't fall so hard while in training, it will just spin out. Underside of pedals and especially the pedal brackets (had to metal file mine clean) is in most danger, as well as any protruding corner (like the side panel extrusions' corners, side panel corners, and the top parts of the wheel, especially the front and back "corners"). The only place where you realistically need to protect against impact are the front and back corners on top.

    I was just out for a ride to the seawall, got a few blocks and a motorcycle cop pulls me over while going from a road to a park. He asks me how long I have been riding the wheel, I tell him a month or more. He says that in Vancouver, it is illegal to ride these EUCs anywhere in the city. No sidewalks, bike trails, bike lanes, nothing. He says he could give me a $530 fine for riding it in Vancouver if he sees me again! He says they are classified as motor vehicles and cannot be insured either. I just spent $1400 cdn on this wheel, it's my commute to work, and my absolute favorite thing in the world and the cop says i will be fined $530 (which I cannot afford) if he sees it again! $#@%!!!! So now I am faced with not riding a brand new wheel, or facing an unpayable fine if I do. If you live in Vancouver or BC, or just give a damn for some reason, please email the Mayor's office, it's easy! http://vancouver.ca/your-government/contact-mayor-robertson.aspx 604-873-7621 Media relations mayor.media@vancouver.ca Address Gregor Robertson, Mayor 3rd Floor, City Hall 453 West 12th Ave Vancouver, BC V5Y 1V4 I have not felt so absolutely devastated in a long time, I LOVE gliding my wheel! /Seppuku

    I thought I'd share this event that occured to me today. I was going on my usual run, but as I was heading down a slight hill on a sidewalk I think I noticed I was going a little fast so I went to lean back to brake. At the exact same time I hit the tiltback speed so I was leaning back with the pedals tilting back. That was not a good feeling! It felt like I was almost going to fall on my back while my wheel kept going forward. Luckily I managed to ride it through , and I think it was just the odd timing of hitting the tiltback while trying to brake at the same time which was unsettling. During those few seconds I hoped that I wasn't overloading the wheel with a very high braking current. Thankfully all was fine. I have delayed the purchase of special riding pants with extra padding, but I might have to reconsider that decision as a hard butt landing would not be fun! Has anyone else run into this rare occurence?

    Very interesting! Not sure why so many manufacturers go for the light and slim route (see Uniwheel), whereas the bigger and stronger wheels seem to sell like crazy as soon as they are released. But the suitcase-like design starting to emerge here is very interesting, towards "office looking", "professional", "business", maybe even flight-compatible light commute wheels. Is the board in the box, or where else is it? Does it not have a retractable handle?

    Bringt ja eh nix was Falsches zu sagen. Ich würde vorschlagen, dass du mit deinen Fragen (die du eh hast) am besten die Polizei so lang nervst bis sie merken, dass Nachgeben weniger Arbeit ist. Nach dem Motto, fährt eh schneller als 6 km/h, wie soll ich das nachweisen damit sie sich den Gutachter sparen können; wie ist sichergestellt dass meine Batterie nicht kaputtgeht; usw. Ich würde an deiner Stelle die "erlaubt oder nicht" Diskussion eher hinten anstellen, erstmal das wheel wiederkriegen (außer es bietet sich im Verlauf an). Danach - kennst du dieses Polizeiinfoblatt aus NRW? Da schreiben sie auch einen Satz (in Bezug auf Grosskopf) dass es keine Zulassungsvorschriften gibt für Einräder, das beeindruckt nen Polizisten ggf. eher als das Gutachten selber. Viel Glück, hoffe du siehst dein (neues!) wheel bald wieder. Fall man sonst was für dich tun kann (mal irgendwo anrufen oder [evtl. bösen] Brief schreiben oder so) dann sags...

    Handsome dog. Love that last picture! I love German Shepherds. We used to own a kennel and a pet shop, and have owned many dogs and many dogs at once for decades. German Shepherds are just perfect to me. I love other breeds too ... we have Australian shepherds now ... but German Shepherds have a huge place in my heart. I only wish Americans hadn't bred them into all that horrible hip dysplasia. They are perfect dogs if you don't screw them up on purpose.

    I didn't put pads on top of the pads the white and black 1600 came with because the bigger battery made it wide enough but I did on the red and black 820 because I feel the extra padding made it more stable to me. Those are LED lights I have in the back and if you look closely there are also LEDS below the red strip on the side the black square is a battery and the green foam house the switch to turn it on I added a few layers to it so it's the same height as the battery

    @steve454 I agree, it's got really nice ergonomics. The downside of the design is that the seams for the battery and control board compartments are inside the wheel which makes them prone to water and dirt getting in. I think that could have been fixed with just a few tweaks though. I'm not ready to part with this wheel quite yet. Shipping to Texas would be expensive though!

    The main thing is the ADC and PWM hardware, this is where most of the STM32 are limited they're very much general purpose MCUs. For example the max PWM resolution on some c2000 PWM is 170ps vs 4ns on the stm32. The ADC conversion is twice as long on the more general purpose MCUs. The biggest limitation is the inputs most of the more general purpose MCUs do not support differential analogue signals or delta-sigma modulators. Most of the newest current sensing ICs need either of those. Then there's other options such as using GaN fets at high frequencies to reduce the need for electrolytic capacitors and using them allows the entire 12V supply to be eliminated. At the moment I have STM32F4 446RE and 405, freescale kinetis kv31 and Ti C2000 f28377S The F4 446RE is a slightly faster and cheaper version than the VESC MCU, 180mhz vs 168mhz 512kb/128kb vs 1mb/192kb. Kinetis KV31 m4 core at 140mhz ?Similar to the STM but quite cheap to buy. C2000 f28377S technically the cpu is pretty weak for general purpose tasks but includes a special FPU which basically has an ASIC that can perform all the complex math needed for FOC in hardware. If that wasn't enough it has a second FPU that can run tasks without using the CPU and has access to ADC + PWM. Also has high res PWM, differential ADC and hardware based delta sigma processing. In theory the C2000 should be much better for an EUC if it performs as advertised. I need to run some benchmarks on them all using FOC loops kalman filter etc. But I don't know how to make the code to test them out.

    Hold on to the furniture then for the first few indoor test runs and pendulums. And you can always use another person. You can, but I don't think it's a good idea for the very start. The flatter, the better. EUCs are much more comfortable on super smooth pavement than rough pavement than non-pavement. I'd also be worried about "locking" the tire in grass if you're really unlucky, especially if you start from speed 0 in grass. Not really a realistic danger, but why stress your new wheel unnecessarily. So pavement or another smooth, possibly softer, low resistance (hard) surface (like a basketball court or such) is best.

    Three ounces in an 18" tire is fine.The key is to make sure you shake the bottle well before insertion.Slime is the sh*t! I turned @Marty Backe on to it when we first met.You wont need the Harbor Freight attachment since you bought the bicycle pump.The Harbor Freight thing is for attachment to a compressor hose.

    You're certainly excited I've seen that ewheels will get new msupers beginning of June, will you get yours earlier or will it be an agonizing wait (been through that, even just for a week, I wanted the thing!!!)? About the fast vs slow thing, fast is easier so going fast-ish in a straight line naturally comes before slow riding and turning.

    As your elder (barely), I recommend that at first it is better to learn to ride slow than fast. To ride slowly is to demonstrate a great deal of control. It is very challenging, as it is far easier to ride fast at first. Until 'it' happens. To ride slow is to gain control and be in charge. I ride so slow sometimes that it seems as if I have almost stopped. Almost. These are very fulfilling moments. Imagine stopping (almost) on a thingie such as this. Control.

    Just my personal opinion, but I think learning on a smaller wheel, especially something like the 14c (which I own and ride almost every day), is harder than the wheel you bought. I learned when I was 56 - and I'm still 56 I'm certainly more risk adverse than my younger years, which is probably why I gear-up relative to a lot of guys that don't

    Congratulations You'll going to love it, and I think the MSuper is a good wheel to learn on (it's more stable than the smaller wheels). Get ready to become addicted. Be patient with yourself. You may be lucky, but more then likely you will have some frustrating days at the beginning, but you'll soon be good enough to have fun while learning to get better. As one point of reference, looking at my log book, it took me about 2 hours (not in one day) before I could ride down a deserted street in a wobbly fashion. It took me about 10 hours before I wrote, "Today it finally clicked", meaning I could turn effortlessly and ride wherever I wanted. Let us know how you progress.

    AFAIK, Ninebots use 15S2P packs, 55.5V nominal (15 * 3.7V), 63V max (15 * 4.2V). 65V would be overcharged (around 4.3333..V per cell)... Maybe the wheel is warning of overvoltage? Is it the original charger or some after-market fast-charger? The output voltage is too high! 3.7V * 15 = 55.5V. For 16S, it would be 59.2V, usually rounded to 60V by the manufacturers (and for typical Wh-calculations of the 16S -packs).

    Just had a play with the Gotway App, the locator was pointed directly at my house. For security reasons I've now turned it off - and recommend you consider doing the same. Just open the app, click 'riders nearby' then 'nearby' then, 'clear location info and exit'. - Ensure it diverts you back out to the main screen - then your home location will be gone.

    You're getting there! Keep at it! I would favor a larger, flatter area. A good trick is to think 'tall' when your riding, even if you bend your knees (which you should). Thinking tall will help tremendously when you're learning to ride backwards. Thinking tall will also help you simply resting your feet on the pedals in a relaxed way. Just try to be as relaxed as possible it's the key to all sports. Cheers

    No, if you read my 1st and the following posts, I explain that it only happens under very special circumstances, at very slight accelerations, just at the start. I never had a problem until now when accelerating fast. But because the problem only happens very rarely I think it will be difficult to find. Besides the mentioned rare events the KS16B is until now a very reliable wheel (more than 2300 km on it). This must be a different problem, because until now I never had a cutoff while riding, and I use the wheel heavily (e.g. with FW 1.23 I once had a short acceleration up to 39 km/h, and there was no problem, the wheel handled it fine).

    Da hast Du vermutlich recht - nur wenn 3 Herren in Blau vor Dir stehen, ist das - zumindest für mich - nicht so einfach. Zu behaupten, das Rad würde max. 6 km/h fahren macht meines Erachtens keinen Sinn. Da wäre eine Bestätigung, dass es schneller als 6 km/h fährt wohl zielführender, da dann der Gutachter nicht erforderlich ist. Und ich habe das Gutachten von Prof. Grosskopf, welches sehr klar und eindeutig ist.

    I've taken some bad crashes on bikes, including one I'll never forget from coming in on a rock too fast to see it. The idea of a big fat tire from an 18 inch or bigger EUC is very reassuring to me. I know it won't solve all problems, but I love the idea of extra safety margins. I live on the outskirts of a city so i can expect to see lots of rocks and branches in the roads, etc. I'm very surprised you're doing so well at your weight on that machine! I've heard so many good things about it, though. It might have been my very first choice, if I weighed less PLUS didn't have so many steep hills around. I need a big power reserve. My city is small, too. You could fit the whole of it in a single neighborhood in Los Angeles with room to spare. The real distances I have to cover are between cities rather than inside mine. For me, that's where all the bad roads and mean hills are. Once I get in the city, my worries are over. If I busted out a EUC, it would be just for fun or some kind of challenge ... or maybe to show off to women who are much too young for me anyway ...

    I had the same thing happen on my old X8 (sold) and even face planted in the middle of a crowded hilly street Another thing I experienced on my GW 14 MCM2 when I started riding down a long hill with a fully charged battery is that it would not brake after a few minutes. I managed to do some S turns to keep the speed down and luckily managed to get down without falling. The wheel felt just like jello. Not sure what happened but I suspect that the BMS prevented from overcharging the battery. It worked perfectly fine after that and it have never happened since - I have never started out on a long downhill with a fully charged battery either... I have started taking it more easy downhills after these episodes. I guess you have to know the limitations of the wheel you are riding

    Ok, went to Amazon and ordered a rearview mirror (thanks Marty Backe's videos for the idea), a Triple Eight certified hard helmet, and wrist guards. Still have good knee guards from rollerblading days. Also, my first smartphone ever, a super-cheapie, just to go with the app. I'm not a big phone guy. Love my kindles Fires but they use the Amazon-specific operating system that doesn't have access to the Android store without jailbreaking, and I'm not going to go through all that. Plus I don't want to crash with them; too valuable to me. Thinking about elbow pads but haven't pulled the trigger on that yet. Oh ... and I read Marty saying he uses Slime in his tires preventatively to help deal with punctures, so I'll go get some of that too. My hobbies are usually dirt cheap, so this is an unusually expensive deal for me ... but it does look like it'll be the most fun I've had in many years. Thinking of using one of our many spare dog leashes as a tether while I learn, lasso-style around the handle ... Oh, and ya know what ... I don't have anything to inflate the tire with ...
