  1. I'm having a similar problem described in these threads. see context for all the details i have https://forum.electricunicycle.org/topic/7670-ks16s-stops-charging-at-76/ https://forum.electricunicycle.org/topic/15150-ks14s-stops-charging-before-100/ Unfortunaety i'm going to mexico for 10 days and wont' be able to troubleshoot. I've emailed Jason from ewheels, and he says it should be safe to ride but be more careful at lower voltage. I'm concerned my packs will become more out of balance or some of the cells might be charging beyond 4.2v to make up for a possibly bad cell (if that's what's causing the issue). I can live with my beloved 18s even at 80% capacity and going at a max of 16-18mph if need be. but if my concern is right, i should eventually open it up and diagnose. I'm a little concerned about dissaseembling it, but I know someone here probably knows of a good guide on this forum or video to look at to help. Do you think my problem below is one easily enough solved by a college electrical engineering student? thanks very much ----------------------------------------------------------------------------------------------- CONTEXT I've had the wheel for 1 yr now, I purchased it from somebody who purchased it from ewheels, but likely the warranty is over. In my year of having the unit, I have charged it to "100%" two or three times (but im not sure how long extra i kept charging when the green leds came on), while mostly keeping it charged around 75 to 80% This just started happening last week, and I've reproduced the problem at least twice (after discharging and riding the wheel and recharging) here some additional information: 1) The charger shows the green LED 2) Connected via Wheellog App it shows 77% charged and 62.4V 3) the wheel itself shows 8 bars 4) I've checked it with TWO ewheels smart chargers at various amps and various % settings. I cannot get it to charge beyond this point at any of the settings 5) the Charger got to around 64.1 or 64.2 v (i've always noticed the charger is 1 to 1.5v higher than what wheellog reports) before the green led on the charger lights up and then it showcases 67.2 - sometimes 67.8v 6) I have not checked the voltage on the prongs of the charger yet. 7) i have not opened the device and measured voltage on the battery pack itself 8) I've charged it in two different places/two different outlets using one of the smart chargers
  2. 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.
  3. Urna Semper Stan O'nymos January 3, 2018 Ooh lala The KS18S The night looks better in electronic shades of green. In the 1930's France decided if the world was collapsing under the great depression, France was, before the final end of civilization, going to finally show the world its superiority in the form of automobiles. They began unceremoniously with push button electronic transmissions that had 6 gear speeds in forward or reverse. Later there were water cooled inline six cylinder fuel injected engines capable of 80mph in the beginning and by the end of 1939 you could cruise at 110 mph in a hardtop retractable convertible down the Champs Elysees on spanked pigs leather upholstered seats blinding all onlookers with spools of chrome accenture off curvy hips fashioned from metal over the fenders and skirts. The styling began, well how do I say this, not so British as to offend the eyes, but wound up evoking the lines and movements of giant chrome accented majestic biplanes glistening in the sky as they roared past the throngs of unwashed hankering for a hunk of cheese cake. These cars hovered more than wheeled on the chassis powered by the thundering inline six dual header sans catalytic converter. Fun names like Delage, and Delahaye, Peugeot, or El Glaoui who was known as Lord of the Atlas and was the Pasha of Marrakesh, ruled the times. No longer was the car just a noisier wagon wheeled moving money pit, less dependable, sluggish, pollution machine of pain and sorrow. Now in 1939 it was fancy and able to go at tremendous speeds in luxury and safety as well. No wonder why Hitler was so upset at the French. It will be told in history books of the future that Electric Unicycles have now reached that similar period in their development. It is so proven with Kingsong's newest release, the KS18s an 18" electric unicycle capable of 30 mph and a range good enough to take you to the Piggly Wiggly grocery store in Zebulon from Rural North Carolina and back. Thats as fast as a horse. Styling of today's so called futuristic wheels is such infantile braggadocio. Yeah? You know what the Segway a1A looks like? Correct it looks like a wheel. How brave those designers must feel. They have reached into the future and come up with - nothing. Im not buying it. Kingsong, like their designs or not, have always been voluptuous with the lines on their machines. I own a 500w KS14 that looks like a stretched out "portable" Singer sewing machine in its plastic case. It really is something out of a 1960's science fiction TV show of what a robot companion would look like in the year 2020, which is only 2 years away so that makes Kingsong almost 5 years ahead of the game already. This new much larger wheeled big brother looks like Darth Vader's helmet if it was pressed in a 3 Stooges sized vice. Oddly enough it makes no difference whether you look at it from the front rear or either side. You will still see the dark side staring out at you from the honeycombed metal bluetooth speaker covers. The KS18s and the KS18ay both have quadraphonic bluetooth speaker systems capable of conversation squashing sound wherever you wish to go. The USB port above the power button assures you that the STREAMING can continue as long as their networks deems so. I would guess the white cases look like a storm trooper's helmet, and they do in all the pictures I have seen them in, which is one. C'mon, who wouldn't rather be Darth? Onto the ride, but wait the app. It has been restyled and much of your well thought out comments were lost in translation, but it is more colorful and it is easier to access the set up modes for speed, ride, and vertical calibration. Vertical calibration is essential to setting up the vehicle for style of lean while on the vehicle. I am short, so I found myself leaning too far beyond the pads. Just enter the calibration mode and lean the machine a little forward. Voila! Setting up the ride is an equally easy task, but not even Confucius himself could solve the speed warning settings riddle. I will be asking kingsong customer support about this paper finger trap where every level I would like to put it at is rejected or fails. So far I have only received the first warning which is set to around 23mph. This machine drives like a Mercedes G class SUV. Perfectly suited for the absentminded fellow or housewife who doesnt always notice that the sidewalk is not ended by a ramp but a curb or the giant root bulge in the road that is milliseconds away. The KS18s has handled both of those obstacles at low to medium low speed without me even having the feeling that I needed to panic or brace for a launch. It has a nearly 3" wide tire and that and the larger diameter really smooth out the worst of the road. Oddly enough, certain smaller bumps act more as ramps than the bumps I was accustomed to treat them as on my 16" V8. The KS18 rides the offroad trails like a Clydesdale who has consumed a liter of redbull. It has power, 1500w of constant and double that at the peaks. It has so much power that I find myself leaning far too forward because of the unbelievable climbing strength and sandiness of the soil it just wants to plough through and will with a little patience and less panicked verve on my part. The KS18s is heavy, heavier still with the 1680wh battery pack, but it handles like it wants to be a baby lamb. It can turn on a dime and head up a leaned over tree if you let it. At first it can handle like trying to retrieve a hat from the ground while closing a diesel truck door. It is that thrill of cheating certain digital amputation that encourages the rider to quickly learn how to carve a 90° corner like Betty Crocker spreading icing on her mother's birthday cake. It is a quick learning curve and one you will want to do out of passion because of the ride the KS18s delivers. I am 145lbs with boots and a hat and just over 5 and a half feet tall, so hearing giants over 6" tall tell me how much fun it is,... Well I was skeptical. I am no longer a skeptic. This thing charges up the steepest hills, carves out a perfect arc on a busy street, and is a champ on grass or dirt trails. Stopping while going downhills is a much bigger chore due to the counterbalance I need to create down steep hills without starting the wobbles. This is getting much better after the first week of riding, and as I get more used to the vehicle's dynamics. The KS18 is remarkably comfortable while riding in foot traffic at slow speed. It is much less noticed than my mTen, perhaps because it is so obvious and therefore easier to predict where its heading. Maybe they just fear it more. Did I mention its heavy? Fortunately it has a space in the tire rim for a lock cable that you can string up to the handle as well. It has a locking mechanism that I am told will disable the vehicle with a passcode. I believe that, since I have been disabled by several passcodes of mine. So I have not tried out this function yet. It is tall, but it comes with a seat that is comfortable and pretty fun in a Charlie Chaplin sort of way. The lights are reversible depending on the direction you are headed in. In other words, if you drive butt first the rear headlight will light up the ground just before you hit whatever danger lurks in the dark and the same if you head face first into life. But hey the tail lights are perfect and activate when braking which is so totally cool! Besides if you are driving Darth Vader's head at night may I suggest some night vision goggles to compliment the look?
  4. Okay... I'm getting so, so, so frustrated with my EUC experience. I really need help. I got my KS18S in late September. I started regularly riding it in late October. In January, it malfunctioned and threw me, sending me to the hospital. The company gave me a new EUC, but since my tire went flat, it's been a shitshow. It took me a while to order the special inner tubes, but I've reassembled the EUC thrice, with it malfunctioning in different ways each time I've tried starting it. I don't think changing a tire should involve directly plugging/unplugging delicate things into the circuit board. The last couple times I assembled it, it accelerated uncontrollably when turned on. Now it synchs with Bluetooth and a loud female voice shouts something intelligible at me, and the EUC itself doesn't move. Overall, I've been having a terrible experience with my EUC. I've been sending emails back and forth with the retailer, but these companies should be providing more support. What's your experience with EUC maintenance been like? Does Gotway provide better customer service?
  5. Hi to all, I am new to this forum and I just own my first EUC ks18s. I just noticed on the kingsong app and wheel log that the battery voltage drops as the battery drains from 100%. Is this normal with this EUC. I am not familiar with electronic voltages. Thank you in advance.
  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.
  7. I’ve been given the opportunity to get a good deal on a practically new 18s . It’s the 840wh version though. I’ve heard that the 1680wh version doesn’t really have all that great of a range so wondering what people have gotten out of the 840. My main consideration here is price . Is 25-35mi feasible ?
  8. 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 :-)

  10. Anyone know of a good tutorial video clip on how to ride this baby sitting down ? I find it very difficult since everytime I tried it, I will be bending down and in a low speed situation obviously. Hard to keep balance that way.. There must be a good technique to avoid a complete face plant. Not exactly my idea of fun.
  11. I just got my new Kingsong 18S today. Been riding the 16S for a few weeks.. A couple of things I noticed with the 18S 1) It hums. Is this normal ? With my KS16S I did not have any humming noise. 2. Because of the height... it now pushes up against the inside of my knees whereas the 16S were against my calf... Considering that not a lot of meat around the knee .. this can be quite painful. Whats your experience ? And how do you handle that ? This was just a quick impression after taking it out to the back alley and rode it for about 2-3 minutes. I havent even pumped the tire up or anything... Would like to hear from anyone who has the 18S. especially about the humming.. It's not loud or anything but I definitely can hear it. I understand it has fan inside.. but is your unit hums when turned on ?
  12. A few months ago, I decided to sell my Gotway 820wh Msuper and ACM to upgrade to the 1300 ACM and the MsuperV3s+. I put my order in at ewheels and have been eagerly awaiting their arrival. A few weeks ago, I started reading about all the drama with the Gotway problems you all have read about I'm sure. With these safety concerns, I really started getting worried. I learned to ride on a Kingsong 14c and wanted to buy a ks18, but they weren't available at the time. I opted to buy the Gotway wheels and really enjoyed them. I have 3 of my children that are proficient riders and we enjoy our trips together. Not wanting to put my kids on wheels I knew were having issues, a week ago I decided to cancel my Gotway order and Jason was kind enough to let me switch my order to the KS16s 840wh and KS18s 1680wh arriving in a couple of weeks. Reading about @Marty Backe and his latest problem and fall on his Msuperv3s+, I'm glad I made the switch. (Marty, I hope your wrist feels better...makes me mad that Gotway puts out this stuff and lies about having it fixed) I know Kingsong is not perfect, but I figure it was time to make the switch. I'm sure I'll miss some things about Gotway, but I'm looking forward to giving Kingsong a try again. I'll make sure I give my opinion on How Kingsong is treating me. Matt
