  1. Hi Folks, I just discovered a strange behavior of the LED ring of my KS-16S after my last ride: The battery was down to 38% and just before the recharge I recognized that the LED ring (on one Side only) lit a little strange: Instead of showing 4 LED solid green, there were 2 green and another white at top of the ring. (on wheel's opposite side the LEDs lit correct). After shutdown the wheel for about 1 hour, the LED rings came up correct again. Have you ever experienced such behavior? Any ideas about the cause of this?
  2. My Speed Reset to 28KMH Max KS16s! Help!

    I have been riding it about 3 months... I had reset it to go 35KPH.. Everything was great until yesterday when I noticed I got the "Please Decelerate" notice and tilt back... but going a lot slower than it should be at. I checked my speed settings on the app and it was set to 35 still, yet it was happening at about 28kph. I can't put in a new code on the speed limit decoding screen cuz once you do it once, you get the same screen as the speed limit setup. I tried uninstalling and reinstalling the app but it still wouldn't bring me to the proper screen to enter a code again.. I tried to install the new version of the app on my android phone from the website but it doesn't download.... so I installed the old app on my friends iPhone and finally thought I had it solved when I saw the proper speed limit decoding screen... I did it.. took it for a ride, and nope... still set to 28kph... I wonder if I need to reset the wheel to a factory default and how to do it. Does anyone know how to solve this? Help!!
  3. Goodbye, KS16B ***sigh***

    Dear wheel, please accept my most heartfelt sympathies. My thoughts are with you, dear KS16, and the Kingsong family during this difficult time. Wishing you peace to bring comfort to your new owner, courage to face the days ahead and loving memories to forever hold in my hearts. Words seem inadequate to express the sadness I feel loosing you. But because winter approaches again, with lots of skiing days and no possibility to ride a wheel, I needed to give you away, after sharing lifes for more than 3000 km. I'm sure you will be happy there. And I, the hollow-hearted preowner, I'll feel ready next spring to take the next step to a KS16S, Gotway Tesla or the like.
  4. Hello Folks, I'm a Ninebot One S2 (S1) Rider and pretty satisfied with that package, especially regarding it's movability and handling. But I'm missing a little *whoom* and therefore I'm thinking over to switch to something like V8 or KS-16S... in the first place. Now I read the rumours about the announced shiny new KS-18L or Ninebot Z, both 18 Inch. So, what is your option, should I Upgrade to 16" - or even better to 18"? What are the advantages/disadvantages? What about the riding comfort (e.g. City ride, long distance ride, gravel road, bumpy road etc) - are there big differences between 16" and 18" or do they behave more or less pretty similar? Will a 18 inch wheel be suitable for inner City usage or is it much less movable/agile, compared to a 16 inch Model? Thank you for you opinions/experiences Rgds, Borg
  5. I stumbled over this seller on Aliexpress, selling accessories for Kingsong 16 inch wheels: https://www.aliexpress.com/item/KINGSONG-16inch-electric-unicycle-All-accessories-parts-motor-shell-Controller-motherboard-Pull-rod-handle-lever-Light/32832356086.html This made me think about if it would be possible to upgrade my Kingsong KS16B to KS16S by replacing my current motor and controller card with new ones? Since I think I have read that the shell is almost the same for B and S. Not that I am exactly sure what model the accessories from this Aliexpress seller is suitable for, you cannot tell from the product descriptions (at least I can't...). But, hypothetically: would it be possible, or if not: what would be the caveats? And would it be enough to replace the motor and the controller or are there other parts that are vital for a successful upgrade?
  6. Hey guys, I play music when riding my KS16, but I want to upgrade the speakers to be louder. Has anyone any experience on doing that? Any problems when changing the speakers that I should be aware of? And what speaker did you try out? I want the whole city to know I'm coming their way.
  7. 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.
  8. Hi guys, To finally celebrate the arrival of the new Kingsong batch to the UK, I am happy to announce a £300 (340€) discount on Kingsong KS16S. "Why the hell does he discount a new model by this much?" - you might ask. This is only because I myself can't wait to start riding one of them, and want few more dedicated riders to join me in enjoying this wheel! The deal will only be available until the end of Sunday, 30th July. With this massive discount you still get the excellent aftersales and servicing done by Project42 UK in London, 24/7 support and return/replacement options. The shipment has landed today, and should be at our warehouse early next week. Reserve yours today: https://proj42.co.uk/kingsong/kingsong-ks16s-electric-unicycle Feel free to reply below or msg me directly if you have any questions
  9. Dear fellow riders, my otherwise quite reliable KS-16B (after approx. real 1500 km, FW 1.25) has recently a few times spontaneously shut down while being pushed with the trolley extended. The power turned itself off without warning and the wheel went limp. I could switch the power on again and at least once it turned itself off again after a few minutes. No problems while riding, only when pushing in trolley mode. WheelLog logs did not show anything unusual until the shutdown. Maybe related: when turning the unit off by pushing the power button, sometimes I get one beep, sometimes two beeps, and I think I once even heard three short beeps when I turned it off. Is there a meaning of those multiple beeps? @Tilmanndiagnosed a faulty on/off switch. It would execute a shutdown triggered through vibrations while the wheel is pushed at slow speed but not while riding when the power on/off switch is deactivated. And it could also produce mutiple beeps. Can anyone please confirm or report of a similar problem and perhaps its remedy (*)? What is the known minimal speed above which the power on/off switch is deactivated in the KS-16B? Or is it deactivated by riding the unit as opposed to just pushing it? Thanks a lot! (*) except upgrading to the new KS-16S
  10. I thought it was about time to refurbish my ks16 for the summer, and I have always jelaously been looking at the matte black shells. First is the before picture. It is actually from a tire change last year, it was more scratches and marks on it now. Next is in the middle of the shell replacement. Just removed the trolley handle to reach the top cover shell. Then a picture of the old shell and pedals (yes I did a try with black vinyl wrapping earlier this year, but I am far too restless to get that nice so I was not too happy about the result). 4th picture is the wheel with new shell and new pedals. Also new side pads without the kingsong logo. Picture 5, 6 and 7 shows some minor additional things. I put grip tape under the pedals. Apart from protect them from scratches I find it to be quite good looking. The very uncool reflectors on the front/rear/side are attached with hook-and-loop/velcro tape on pads cut out from those bumper foam strips that I have seen a lot of you people on this forum are using as wheel protection. The cool thing with the uncool safety reflectors are that they are actually certified for use here in Sweden, which not many reflectors are, actually I have only found 2 or 3 brands that are legally allowed (and all look this ugly, maybe that is a requirement in the certification :). I have also put on a light which is a lot brighter than the built-in (1600 lumen). It's a bicycle front light/headlight with a small battery pack that I fastened against the trolley handle. And as you may see I have also put on some rubber strips to protect the wheel. I have no illusions that they will keep this wheel looking clean like this forever, but maybe a little longer than otherwise. Shell and pads are from Kingsong Europe, bumper foam and new pedals are from Aliexpress. Rubber strips, reflectors and light are from local Swedish hardware stores.
  11. Hi! For reasons, I had to do some disassembly of the trolley bar from the KS-16. When I was about to put it back, I could for my life not tighten the screw that is positioned against the bottom of the trolley bar (I only did this on one side, have not touched the other bar). I pushed the screw very hard while trying to tighten but it was just rotating on and on without ever attach to anyhting. I even caused a small crack in the plastic around because of the force. The thing is that there are a couple of washers on this screw. three I guess, or perhaps even four? And I removed those washers and tried to tighten the screw anyway. That went very well. Since I am a complete loser in regards to mechanical stuff, I have no idea how bad it is to leave these washers out, or if it is bad at all? As far as I could conclude, this screw is only used to keep the bar more stable in position? Not that it would get loose without it, since it is also fastened into place with the help of a metal disc. Anyway, the screw I am referring to is the one pictured in the attached screenshot.
  12. I have a couple of screws on my KS-16 where the head has been slightly damaged. Since they are becoming quite hard to tighten/loosen, I am thinking of replacing them. But what are these screws called, what's the screw type I should look in search of replacement screws? It's those small screws that fixate the outer shell against the inner shell. And also used to fasten the LED strips on the outer shell...
  13. Kingsong KS16 stickers

    I saw picture here and there of KS16 wheels customized with special stickers. I was looking on internet but could not find any vendor for KS16 stickers except for the pad, nothing for the entire wheel and the complete shell. Probably some are home made but I doubt all the one I saw are like this. they must have been bought somewhere. If anyone has a link to share, would be great.
  14. Hi mates, as promised I did some tests with the new firmware 1.25 on my KS16B, because there was the rumour (or info) that the maxspeed is now not lowered at 50% battery capacity, but at a lower capacity level (which would excite some folks including myself :-) ). Short answer: Yes, as an opposite to Ninebot (who worsened the firmware of my former MiniPro) Kingsong continuously enhanced the KS16 firmware, and now maxspeed is lowered around 20% battery capacity, not before. For me that's great, although it means there is a little bit shorter range, if I always drive at maxspeed (which I tend to do). What I also like is, that the maxspeed is not hard cutted from 30 to 25 km/h at a specific capacity level, but it goes down in a smooth reduction curve, starting at approximately 20% battery capacity. Long answer: The test was done on a nearly completely flat terrain, and my KS16B has alarm1 and alarm2 turned off, and alarm3 and tiltback are set to 30 km/h (the maximum possible). The screenshots were done when the wheel was continuously beeping, but still no strong tiltback, so not at an absolute peak speed, but at a maxspeed which can be kept for at least 5 seconds or more. This way I hope to have comparable results. The first screenshot at 63% capacity level is what you would always expect, also with firmware 1.23, the 30 km/h can be easily reached: Already more interesting at 34%, the set maxspeed can still be reached easily: 6 km and nearly 11 minutes later at 30% capacity, still no maxspeed reduction: Half a minute later I had to climb a small hill, still possible at full speed with 25% capacity: 3 minutes and 2 km later, at 21% the speed reduction is for the first time recognizable: But it's still higher than 25 km/h, the maxspeed seems to be reduced in a soft way, not with a hard cut: Now, only around 10%, the 25 km/h limit seems to be reached: And kept until the battery is nearly empty (from App point of view): Also interesting: In the Wheellog graphic it can be seen that the maxspeed is always the same (around 30 km/h) from begin on until approximately between 12h16 and 12h17, and from then on during the next 15 minutes it goes smoothly down from 30 to 25 km/h, no hard cut at a specific capacity: My conclusion: I like what i see regarding the maxspeed reduction, it is done in a great way in a responsible manner, from my point of view ! I also encountered a rather strong tiltback in the last quarter of my ride, when I was driving slightly downhill and did a very strong acceleration from nearly zero to above maxspeed. The tiltback was as strong as I never had it before on my KS16, so I was a little bit shocked, although it was no problem to decelerate. Regardless if this is also new with 1.25 or if it was already like that before, this is a good safety feature, because I was REALLY forced to decelerate by that ! To me the KS16B became an even better wheel by the firmware upgrade, although I already was very happy with it before !
  15. I've messaged Tina regarding some things I didn't like about the new firmware update v1.23 she told me unless it's a problem for most people she wont get the developers to change anything. (Please remember this post is only for firmware V1.23 if you have not updated please do so and contribute to the post.) The purpose of this post is to get Kingsong owners to speak up what they would like to see in the app(please be as detailed as possible) I have two problems with the current firmware and App: Speed reduced at 25km/h at 50% of battery left. My wheel is currently speed unlocked so I can ride at 30km/h once battery is at 50% I can only ride at 25km/h. I want speed reduction to kick in at 20% or 25%. Exceeding speed Alarms be able to switch and turn off between Beep and "Please decelerate" and Vibration/Shake Currently there is no way to change the way it alerts you. When I first received my unit and rode past 30km/h at 90% of battery my wheel would shake/vibrate and if I pushed it even more it would start to beep. The constant beeping is very annoying for me and I usually cant hear it because I'm wearing earphones with music on. I want to be able to adjust the way the alarms are controlled allowing the rider to make decisions depending on the way they ride. EDIT: I've condensed all the posts and links to make this post easier to read. Below are other suggestions from other riders. More customizations on pedal tilt back Speed at which they tilt back Angle at which they tilt back When wheel is resting change 'fine tune' pedal angle Bluetooth password Rename KS device Option of Larger pedal options Set voice prompts as off on default can be turned on through app Headlights brighter headlight preferable Settings for flash options of light Firmware updates not to consume too much power MAJOR CHANGE FOR REDUCED SPEED NEEDED
  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. Hello ! As partner of Kingsong Italia we have the new ks 14D available in stock. Buy at eRuota.com
  18. I had been happy Ninebot user since early 2016, with 2000 km range experience. I have decided to make step forward, and switch to the stronger wheel - I have decided for KS16 with 680wh A few pluses: - higher torque, - much longer range - valise type handle - integrated lights - better stability and nicer ride In general - very good wheel, however I have found that original KingSong pedals are really bad in terms of grip, rubber is soft and heavy, moreover spring based holding mechanism is terrible. Please see below my mod for the pedals: - skateboard grip offer much better stability even in wet conditions - magnetic locking mechanism is easy to lock and unlock by small kick in the lower part of the pedals - pedals lower parts are quite useful! - mod allows to make the unit lighter - KS16D with 680wh battery weight is now 16,42 kg - basic CAD knowledge and 3d printer allowed me to design and print needed parts, proper mounting of the plastic inserts require drilling 3.2 mm holes in the aluminium pedals and taping the holes with M4 thread. Experience in drilling required in order not to drill through the pedals 14 mm round neodymium magnets inserted in the pedals and into the white side bumpers are sufficient to hold pedals up. - 6 pcs of of 10mm and 6 pcs of 8mm long M4 screws are needed, also 24 washers to equalize uneven cast and mount the pedals (US modders can adapt to the locally available imperial system screws) - if somebody is interested in obtaining .stl files with plastic insert and side bumper (to be printed on the 3d printer) let me know. - mod is reversible - it is possible to unscrew pads and insert rubber back into the pedals. The next mod which I decided to go for is to add brigher LED red lights on the back - see results in the next pictures.
  19. Hello Wheelies My KS16 Shows after switching on 4 LEDs crosses and beeps continuously, and Serial number is no longer displayed in the app . Can anyone tell me what error message that is?
  20. KS16 tilt forward in rough terrain

    Hi, as Kingsong riders know, the KS16 (and possibly KS18 too ?) tilts a little bit forward when entering curves. I got used to that (though didn't recognize such a behaviour at an Inmotion V5F+ for example), and its no problem (actually I calibrated my KS16 to a 3 degree angle and am thinking about increasing it to 5 degrees). But, what really disturbs me, is, that the KS16 tilts a little bit forward when one enters the meadows or rides on a bumpy road (e.g. gravel road). This makes it more difficult than necessary to feel comfortable on the wheel at offroad rides. What is the reason, why did Kingsong implement it that way ? I would strongly prefer if the wheel keeps the same angle, regardless if I drive on asphalt or a bumpy offroad track.
  21. I'm thinking about what my next wheel should be. I'm pretty much set on going up a notch for a 16", and it looks like Inmotion v8, KS16(s) and Gotway ACM are the current contenders for best 16-inchers of 2016. Seems like V8 scores here best for quality, reliability and low weight, less for ergonomics and range, ACM best for speed less for overall quality, and with the KS16 handle's great, but the "hello kingsong" is a show-stopper for me, but still hoping they'll finally add an option to kill it in KS16s... Anyways, quite a few people have compared KS16 to v8 (like below), but how does ACM compare to both? any first hand impressions? set the quality and small features aside, it looks to me like performance-wise it beats both v8 and likely the upcoming KS16s too. edit: found this comparison ACM to KS16, but it's not very elaborate edit2: a comparison of V8 to ACM by @Tishawn Fahie (brought up in the discussion below). it's a bit lengthy, but basically praising features and quality of V8, but still preferring ACM for its speed, power and riding feel.
  22. I was shocked when I saw this video! The motherboard sits on top of a hole without any separation from the tyre... I guess thats good for cooling it but as the weel spins water may freely be splashed onto the motherbard, same I guess with any pebbles. Water may shortcircuit the motherboard even if its not raining and we just happen to ride pass a little pudle of water! Can someone please tell me that Im wrong?!!

  24. Hello Everyone, I'm new to this forum and fairly new to riding electric unicycles. I just recently began riding an EUC after spending the last year or so riding a boosted board and Onewheel. I wanted an 18 in wheel, but the ones I wanted were not available at the time. I ended up purchasing a KS 14c with the big battery from Jason at ewheels who is an outstanding dealer by the way. This became my first wheel and I have become fairly proficient on it and like it a lot. I want to purchase two other wheels to enjoy and ride with my family. The three I have narrowed it down with are the KS 18, MSuper v3 and KS 16. I like the idea of the 18 inch wheel for increased stability, but I do like the design of the KS 16 and it's trolley handle. I'm 44 years old and don't push the speed limits to the max. I do like the large foot pedals of the MSuper for my size 12 (US) shoe. I'm 6'3" and weight about 185lb If that helps any. Any input would be appreciated. Of these 3, which are your favorites. Feel free to add other suggestions if I missed one that should be in the list. Thanks for your help, Matt
  25. KS16 battery questions

    Hi everyone, I've been reading up on EUCs for some time (lots of info to take in) and I'm thinking about getting one, more specifically the KS16. However, I'm wondering if the 680wh or even 840wh is needed for decent range and good backup power in the long run. Is the 520wh pack considered too small for most with KS16? Is anyone familiar with the 520wh KS16 this shop is selling? http://airboard-shop.se
