  1. Heyho... Finally some words and Pictures about my new KS18S... Let's start with some Pictures: The wheel: Some ingredients: and: Give this Outcome in the end (Really dont like the KS Advertising :-) ) Open Trolley: Mud Guard: Some words to the wheel: (Some Points i "lend" from another KS18S owner, as i am lazy and can't invent the wheel new) Plus: - Extreme "hard" driving mode, even the softest mode is stronger than my GW V3 67V - Seat is included and can be used on Long rides - Powerful, visible and reversible front and rear LEDs - This is the most powerful wheel produced by KingSong to date, both in torque and Speed. - fat Tire of 2.5 , extremly Grippy, Kenda Manufactered - Built-in fan to avoid overheating (starts at 54° Celsius and stops when brought down to 40-42, don't nail me on exact numbers) works flawless - Old Shell delivers really great stability while driving as it is leaning to the knees(once u are used to it) - 4 speakers, they seam a bit dump first, but on driving Sound excellent! - Excellent Build Quality with Focus on safety -fat wires, mosfets, axle etc (see later photos) Minus: - No trolley: But i have done somethin against that - No mudguard: But i am experienced in building one :-) - Old shell, its very "high", thats very different driving style from the other wheels of the market thus requiring a time of adaptation ? Can also be seen as positive But at all i am not good in listing, i better find my own words: This wheel is a powerHorse!!! The pedal Feeling is rock hard, on accelerating and braking there are nearly no movements of the pedal. This goes so far that when i step back on my Gotway V3 67V that on this wheel i am afraid of the pedal "sacking" for some moments, as you get used to this rock hard pedal Setting on the 18S so fast. Also The 18S main difference from my old 18A is that it is really, really agile and reactive. Where my 18A was sluggish and hard to idle, because slow in direction changing, the 18S really rocks...This has an disadvantage also: When you Need to carry the wheel a bit longer, over some stages or a barrier, you definitly have to Switch the power Off, because if you lift it up and dont have it perfectly grabed in the middle, the wheel/tyre starts rotating so fast and flippy, that you can not calm it down by moving into the other direction anymore. It reacts that fast...and accelerates like a rocket. As this question will certainly follow: Yes, it eats up my Gotway V3(67 Volt 1160wh) to breakfast....Easy! It is way harder and faster, way more powerfull. So this seams the only left competitor against the GW 84V rockets, but i cant compare it fairly to that...as i only have some minutes on a v3s+ until now. Hope on a Meeting we can do some comparison between the V3s+ and the 18S in drive behaviour. But i have to say that i doubt that the 18S can cope with the 84V, as it's just 25% more Voltage.... Where it stays out is the build Quality...and the attemps of KingSong to make their wheels safer, here some photos of the inside with some Explanation: I have open it up and all the wiring is top notch and on really thick wires. KS brings their Motor wires through one axle and the sensor wires through the other axle. The Motor wires...i found no AWG on the cable, but a print saying 2,5mm .....so each of the Motor cables is 2.5mm and it is only one hard strand (not multiple strand wire)....i guess on this there is no Need to fear heat anymore! Under the green protection are the 3 Motor wires...as you see all wires nicely hold together: Try to shoot the print on the Motor wires(3 black cables)...These wires are each just "one strand": The batteries are paralled and all go into one Connection Board with PCB, where each Batterie pack is secured by a fuse, so if one goes crazy or dead, your other batteries work on! Here you can see the PCB-thingie(it is under black folie)...the PCB inside has 3 x 40Amp Fuse, one for each Batterie: The axle has getting thicker than on older KS: End of Part 1 :-)
  2. Here’s my DIY ‘suspension’ cushion to make the ride smoother
  3. I got my 18S yesterday and the complaint I have with it is that unlike the 16S which pushes against my meaty calves... the 18S sits high so it pushes against the inside of my knees ... With less meat than the calves.. this is quite painful. And the only thing I seem to be able to do to lessen the pain is to ride with more bend in my knees to widen my legs out ... With this posture, any prolong period causes back to ache. Does anyone with 18S have this issue ? (pad pushes against your knees) If you do, what do you do to lessen the discomfort ? I tried putting on volleyball knee pads to cushion it against the EUC pads.. .but that just makes my knees even wider apart and feet farther positioned to the edge. I think if the pedals are wider.. this could allow me to move my knees away from the unit to lessen the pain.. but as it is.. I hardly have enogh room to stay on as it is. Strangely, my wife said she doesnt have this pain. May be its my boney knees. I dont know.
  4. 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:
  5. Kingsong app not scanning

    My kingsong app was working fine up til this morning.. when I uninstalled it .. and tried to reinstall the app. Now it doesn't scan looking for the unit. Does anyone have this issue ? I heard that there is a beta version of the app. One that looks like here http://www.szkingsong.com/list-30.html However.. when I downloaded the android version.. it's the same old greenish app I had before. And now it is not even scanning ... Thoughts ?
  6. Hi KS16S owners, could you share your experience with the wheel a little bit ? Is it as reliable as the KS16B, what do you like, what do you not like, did you have an accident because of a wheel malfunction, all these would interest me. I intend to upgrade from my KS16B to the KS16S, not only because of the 5 km/h more maxspeed, but also because of the little bit longer range (I have the 640 Wh version). Thanks in advance for sharing.
  7. 16" Tire Width Options

    Curious to see the favorite tire size preference for the favorite 16" EUC category....
  8. Kingsong 16s 1000km review

    I have finally crossed the 1000km mark on my first wheel, the KS-16s. I have been riding around 2 months and have learned a lot in that short time. This review is going to consider the various use cases one might have for the wheel and talk about my experiences in various scenarios. I primarily use the wheel as a commuter tool to get to school and back. This is a 7 mile trip on a fairly long/steep hill. I live at the top of the hill so I climb the hill at the end of the day when going home. I have also taken it on group rides, used it to deliver for a courier service, and used it as my only mode of transit in the city for the last 2 months. As a commuter wheel it has a great blend of maneuverability, speed, stability, and size/weight. It has enough range to get you around a dense city like NYC or San Francisco without any issues and enough speed to keep up with most non-car traffic. I generally beat buses in the city to their destinations since they have to stop so often to drop/pick up passengers. It is light enough to carry up some stairs if needed and small enough to stash under your table in a restaurant or classroom. It is my current go-to wheel for getting around town and performs well in that capacity. But... as I've ridden more I realize that the wheel is actually a compromise on all these factors. While it is a good size, I have found it is a bit cumbersome in tight, crowded restaurants. The elevator broke in my building at school which means I have to climb 8 flights of stairs every day while carrying this wheel - that is pretty challenging. On group rides with Monsters and Msupers I definitely could use a bit more speed/range. The Mten 3 crushes it in maneuverability and size. So it is not a perfect wheel by any means but it is definitely a great blend of all these characteristics. I have crashed the wheel twice at top speed. Once early on when my confidence was greater than my skill level and I hit a manhole cover that was recessed into the street about 1 inch that sent me flying. Another time I hit an unpainted speed bump on an unfamiliar road that I didn't see. Despite at least 2 direct full speed impacts into the street curb the wheel still rides just as well as when I first got it. It definitely looks worse for wear and the case is literally held together by duct tape on one side now but that doesn't stop me from enjoying riding it each and every time I leave the house. I start getting early tiltbacks once the battery dips below around 30%. I wish this was a bit lower but I suppose it is a nice, safe, conservative number. I have kept records of the miles I have gotten out of each charge and tried to calculate the WH/mile for my weight/riding style/location/temperature. But in the course of doing so I feel like the battery % reading in the app may not be 100% accurate so I'm not sure how much value there is in it. The section of the battery from 100%-80% lasts a lot longer than the chunk between 50%-30%. I consume anywhere from 22-30 Wh per mile. So if I am planning that gives me an effective range of ~19 miles before it starts to slow down and another 3-4 miles before it turns into a ninebot. So actual practical use range for me is approximately 20 miles. This is plenty for commuting but is a little on the weak side for day trips and leisure rides with big groups. You can eat up the battery in a little over an hour in those scenarios. If I didn't have to climb 8 floors of stairs I think I would commute to class on an 18-inch wheel like the Msuper or one of the upcoming 18" wheels such as the ninebot Z10 or KS-18L. If they don't fix the elevator I will need to seriously consider commuting on the Mten. Or maybe I'll just keep using the KS and tell myself my shoulders and legs are going to be amazing soon. Anyways I know the 16s is a popular wheel and I thought I'd chime in with my thoughts going from absolute beginner to at least intermediate in a very short time period while really relying on the wheel for all my transportation. If anyone has any other questions I'd be happy to answer them.
  9. Important part first: Here's how I fit replacement power filter capacitors in a KS-14C. It solves the problem of constantly bending the leads when you have to access the batteries, and shortens the distance between the second capacitor and the circuit board, which increases its ability to do its job. I came into possession of a faulty KS-14C from electricunicyclereview's closing, along with a new control board and batteries for it. It would turn on and run, but had very low battery and wouldn't accept a charge. When I opened it up I saw that the power filter capacitors were blown. I put the new circuit board in, and it would boot up but not balance or light up the battery indicator. It probably just needs to be configured for the first time, but I figured that since the original board was functional and just needed new capacitors, I'd try to fix it. I realized the replacements I'd gotten were slightly skinnier, enough to fit in the circuit board compartment lying flat. I mounted them as such, put everything back together, and it works! I also replaced the battery with 2 packs, and discovered it had a few bad cells after tearing it apart. The rest are good, so they'll be useful for other EUC-related projects. In researching the repair, I discovered that the capacitors are less effective the further away they are from the MOSFETS (in terms of electrical path) It has to do with impedance and smoothing the voltage ripple - I suspect the blown capacitors contributed to damaging the battery pack, perhaps being blown during an over-voltage downhill surge that then killed a few cells without the capacitors to smooth the spikes. I also learned that the wires between the batteries and an ESC should be as short as possible, to reduce impedance (which I understand to be a sort of "lag" between the voltage dropping and the batteries providing the amps to restore it, which the capacitors are there to fill in for) SO, it follows that shortening the battery wires as much as possible and installing larger power filter capacitors would be an overall "upgrade" to unicycle electronics, their robustness and its ability to handle bumps / uneven terrain without as much pedal dip, which is better for the unicycle and the rider. Thoughts? Some designs have up to 6-8" of wire that could be removed, and according to this forum post, that would be worth doing.

  11. KS 16 - B Not Working

    Good evening everyone, long time reader, first post, The following situation occurred suddenly this evening, please read and share your 2 cents. Was out on a evening ride, when i stopped to have a piss, the sun had just gone down... I then returned to my KS that was leaning against a park bench.. i reach for my unicycle, and immediately notice it is not balancing anymore, i try lifting it, nothing... then i remember a similiar case and i predict i will not be able to shut it of, i try, and yes, the euc will not shut off, i wait one minute and try to connect with my phone, it connects but no information is available, its like the app is -empty- i continue to try to shut it off, after a few tries it gives a long beep and shuts off. now of course i am feeling optimistic, so i go ahead and turn it on again, only to observe the following: Some more info: battery level was at 62% at time of incident. Total distance about 1300 km, we have suffered some minor crashes along this way, we've had a broken fuse about 2 months ago, nothing seemed to be out of order before the defect, sound and tingling in the toes felt good. Any ideas what i could try?
  12. Did you notice that?
  13. https://worldbicyclerelief.org/en/ and there are many other similar bicycle-oriented humanitarian efforts. but we all know, here at least, which of the two to go with instead of wringing his panties along with putin over the AI apocalypse, mr. musk should devote part of his efforts, since batteries are a huge part of his game, to the development and permeation of awesome eucs and charging centers throughout the world!

  16. Hi folks, I was annoyed by running into over-voltage trouble everytime I start with a fully charged battery and have to run downhill. For some time now I used a modified charger with reduced end-voltage, but I wanted to solve the problem by its root. Together with electronics developer friends we created a circuitry that activites a load resistor, whenever a certain voltage level (67.3V) is exceeded. Such a circuitry is called break chopper. It helps breaking any kind of motor/generator drive. I installed high power LEDs (2*100W) into my KS16 as the load resistor and I am fairly satisfied with the function. I also made experiments with halogen lamps as the load resistor, what I show in the video too. Such lamps radiate away the largest part of the braking energy so it has not be spread by heat sinks. Besides the LEDs, in the second part of the first video I use 3*150W /24V halogen lamps as the load, but these seem a little oversized. In the second video I do the same track (140m descent) with 3*75W /24V lamps, what works as well as the 200W LED-load. I hope you enjoy the nerdy experiments and light show!
  17. Some of you in So Cal may remember when @Marty Backe sold me his KS14C just before the fuse blew. Fortunately I was only a mile or two away from my spare wheel then, and not 8-9 miles like other mishaps. Wait! what if you are 6,7,8 miles away from help and you have a blown fuse? Thats what I was thinking, so I bought a pack of 25 fast acting 40amp mini blade fuses, took one out for the blown fuse and taped two fuses to the inside of the battery compartment as shown below. 🤓 If anyone needs a few fuses 40amp, let me know. I still got 23. Wait, 21 after I tape two more in the 500w kingsong too. EDIT- the fuses are that cellophane fuzzy thing just to the right of the single fuse just above the beige battery connector.
  18. Hello all, Seamlessly, I just created new section a website in order to make me some money, as I was looking for a way to extend the life of my site dedicated to the Mini (mini-j.jimdo.com). So I took the decision to become "affiliate" to online merchants DJI, Aliexpress, Gearbest, Ebay, Amazon (It/ Sp/ De/ Uk/ Fr/ Pl/ ect...except US), Lazada, they have accepted that I incorporate their affiliate program. How it works? if the person, who clicks on a link from my site, buys the product, I earn a small percentage (from 1% to 7%-10% max). the click does not pay anything. You can translate my site in your original language there is the widget googletranslation at the top of each page So I have referenced more than 350 products, Mini, EUC, (It is only the beginning) and spare parts, accessories, drones, 3D printing, etc ... It is an international database, of everything that exists in these different merchants. I have not included your local dealers. They also have a wide range of products, accessories and spare parts to sell you. (unless they ask me to be affiliated with them😘) All I want is to continue my Mini-J blog. Be able to make it more complete, more current, and always stay the first blog that talks about the Mini. It is therefore thanks to your purchases that my blog will continue to live. Thank You very much Friendships from Bordeaux Joris/Mini-J/Jojo33 *P.S: - first for the Ninebot Mini https://mini-j.jimdo.com/shop-guide/mini-mini-pro-mini-plus/ Mini-Mini Pro-Mini Plus Accessories-Customization 3D Printing Battery & Charger Bodyframe Bluetooth-Fine Front-Back-Light HandleBar Hubcaps Motherboard Fenders-Mudguards Pads & pads sensors Steering Bar & Steering Shaft Tire & Motor-Wheel - a page is dedicated to EUCs (Gotway, Ninebot, KingSong, soon Rockwheel item, etc..accessories, spare parts..Ninebot Elite, Xiaomi MIJIA....) https://mini-j.jimdo.com/shop-guide/others-euc-more/ Others EUC & more...

  20. Hello, Need your advice: Going to buy a KS16S. Which iOS (preferred) or Android App will work, which disadvantages do they have. Please no guesses, only experiences with KS16S. Thanks a lot.
  21. After having used an electric skateboard around town (mainly for transportation) for the past couple of months I realized that enough of the roads around here are a hair too crappy for said skateboard — the board can take it, but I find the ride too rough. Now I'm thinking about switching from the skateboard to a KS16S (or a onewheel+, but that's another story), but having watched a crapton of EUC youtube videos and having browsed thru that "If you fell off EUC and got injured in the last few years, how are you all doing now?" thread, I had a few questions about cutouts: 1. How common are cutouts? As in are cutouts one of those things that aren't so much a "if you have one" thing as a "when you have one" thing? 2. From what I've seen and read I get that the beefier the EUC, the lower the risk of cutouts, and the closer you hang out at the max speed of your EUC, the higher the risk of cutouts, but what are some other things that raise or lower the risk of cutouts? 3. If I'm around 175lbs (80kg) and I don't plan to go much faster than, say, a bicycle that's cruising around (that's about as fast as I care to go on the electric skateboard), are cutouts something I should worry about if I'm looking at a KS16S? And unrelated to cutouts, I have two other noob EUC questions: 1. If I'm buying in the US, is ewheels.com the way to go? Or are there other sites I should also be looking at? 2. Is carrying grocery bags in your hands while riding an EUC a bad idea, balance-wise?. What about shifting the bags around like you might do if you were walking around with heavy bags and your hands were getting tired? 3. The inmotion V8 was the EUC I was actually interested in (because in addition to the 16" wheel and extendable handle in the KS16S, the V8 also had a kill switch for lifting it) but it sounds like ewheels.com is not going to carry it anymore, and I also got the impression that ewheels was the only official distributor of the V8 in the US. Are there other legit outlets that will now carry the V8 in the US?
  22. Grüß Euch / Hi All, Deutsch: Ich würde mich freuen, von anderen Einradsüchtigen in Österreich zu hören, und vor allem wo und welche trails ihr so befährt ! Ich werde von Zeit zu Zeit ebenfalls Fotos und Infos von netten EUC Touren posten, die ich gemacht hab. Postet in Englisch oder Deutsch, wie ihr wollt. English: I want to start an Austrian group. Feel free to post in English or German (I live during the week near the UN-City in Vienna, and spotted some EUC riders entering it, maybe they don't speak German). From time to time I'll post infos and fotos about nice EUC trails here in Vienna or in Styria, where I originally come from. Maybe others can do the same for the areas they live in. Cheers, HtG
  23. Hellooooo My KS 18S arrived!!! I am very happy
  24. Kingsong 14(c), 800w, 520wh for sale in the US. $600 obo. Runs and charges fine. This was one of the earliest 14(c) 520s sold in the US so max speed is locked in at something like 18mph and app connectivity too difficult for my 45 year old mind. I did get it to play music once. As soon as I got the wheel I smothered it in gaffers tape to protect it during my learning period. Great wheel that runs fast and hard. Great for an excuse to visit a friend that is working at the ER for a few stitches. No charging or charger issues. Selling to buy a camera. NO WARRANTIES. Caseysearsatty@gmail.com (423) 232-0038
  25. Steep Learning Curve

    Rider's log (test ride #2): Slow going... Learning to ride a unicycle is hard (and tiring). Balance takes a lot of practice. No injuries to report... On my first test ride I was very timid and extremely afraid of falling at any speed. I barely got to the point where I could travel a few meters without losing balance when my inner tube's valve snagged the housing and tore. (Deflated tire caused valve to stick out at a precarious angle.) Bonehead rookie mistake to avoid -- Don't forgot to check if there's sufficient air pressure before a ride. This is me putting on protective gear to ride my KS14C... This is the park where I go to practice riding my wheel. (Note: it's a hot 90 degree Florida afternoon and learning to balance is exhausting.) This is 'the slalom' where I practice low speed maneuvers (6-12kph). (Note for beginners: These posts are the perfect height to reach out and regain balance...)
