    The Z10 is in the house Today I received the Z10 from Chooch. I am going to give him a hard time, but only because he's causing me some unneeded work and stress. It's all in fun though, but he deserves it As you know by now, the tire valve access is via a port on the side of the wheel, and requires a long (~4-inch) valve extender to access for filling. As shown in his video, he didn't care too much for the one that ships with the wheel. So he opted to use an existing one that he had from an earlier Ninebot wheel of his. I guess he decided to throw away the one that comes with the Z10, because it wasn't in the box. And I don't have an old Ninebot wheel kicking around the house. And the tire was essentially flat because that's how he liked riding it. With my additional 55-pounds the wheel was unrideable in the flat condition that it was in. Imagine your feelings, having just received one of the coolest wheels being made, and only being able to look at it. After calling various stores I realized that I'm not going to be able to buy an extension tube locally and it could be a day before I could possibly bum one off a local rider (nobody lives nears me). But then I decided to try something ghetto. I drove to a local PepBoys and bought a pack of four 1-inch valve extenders. I got home, ripped the package open, and screwed them together end-to-end. It worked! I as able to fill the tire The air in the tire did not register on my gauge, so Chooch really likes it low. I pumped it up to 20-psi for now. Next, he didn't send it to me charged or clean. Looks like it came right from the trails. And you know those pads he taped to the shell? Well, he used Duct Tape. You now what that means right? Lots of sticky residue on the shell. So I'll be spending a fair amount of time cleaning it so it looks purty in the videos. There, I feel better now. Chooch, you owe me one Very First Impressions This is one very nice looking wheel in person, and damn heavy. When I showed my wife, her unprompted reaction was, "That's cool looking". I don't think she's said that about any of my other wheels. This wheel is going to turn heads for sure ? Last night I had downloaded the Ninebot Android app; apparently only one is used for all of their devices. Wow is all I have to say. I immediately connected to the wheel and I didn't have to create an account or give my social security number. It knew everything about the Z10 and was super easy to configure. Why can't us KingSong and Gotway owners experience the joys of an app like this? No Chinese. Just my native language. Kudos to Ninebot. Any way, the wheel is charging. After the charge and cleaning, my first ride will be a night ride. I'll try and capture all of the light affects on video. More to come of course. Tomorrow is a Demo day for anyone in Southern California who wants to see and ride it.

    This is the information we have so far: The Wheel had 7000km, in 9 months, when it was sent in for repair in late November It had sustained multiple crashes (David had written this in an earlier communication), destroyed inner-shell, chew-up motor wires, which also destroyed the controller; it was a unique specimen of a damaged Wheel. We have a good documentary trail for this repair. When it was sent back out, everything was changed except the battery pack. There was no visual indication, or other evidence that anything was wrong with the pack at that time. Assuming that it had done similar mileage over the intervening 5 months, it had then clocked up a further 4000+ km; possible subsequent crash damage? Quite probably. He had been using only the standard 2A charger with the Wheel, he has also confirmed it was not charging at the time it lit up. His therapist is another first-hand eye-witness account who can corroborate what exactly happened at the time. I will be contacting both the therapist & the NY Fire Department to assist in the investigation. At this moment, it's not clear what evidence is recoverable from the site. If one had to speculate into causation, then based on what we know from the V10F affair, if water does permeate into the cells, accelerated corrosion will cause a short between the electrodes, creating a runaway cell thermal chain reaction. Understandably David is in a state of shock & is angry, replacing the Wheel is small beans; what is important to me, is that we have a clearer picture on causation, so a similar event does not happen again. As bad as the situation is, it might have been a whole lot worse!

    After two weeks of being held up at Customs, the long awaited pre-production 18XL turned up yesterday For some context & background: I received one of the original 18L pre-production Wheels back in April; the packaging foam wasn't properly thought out, so that the power button came into contact with the foam, causing it turn on & burn-out the control-board before even taking it out of the box. This time round, KS have really taken this issue seriously, so that the foam is positioned below power button, & if it were to somehow turn on, the Wheel is shipped with the software lock enabled—they've started doing this on all their Wheels. I've now accumulated about 1000 miles on the 18L, switching from an early V10F. While discussions on the V10F are bound to bring on a fierce debate between owners, it was, probably still is, the most ergonomic & comfortable Wheel ever made, with its comparatively narrow body & large pedals, that fat 2.5" wide tire, made for a wonderful ride experience. I switched over to the 18L mainly because of the V10F's throttling on <60% battery became annoying, while of charge remaining, the 18L satiated this need to maintain a >40kph cruising speed, but it was not without some loss. Within a week of making the change, I hit an unmarked speed bump, resulting in an unplanned dismount crash... While I was wearing minimal protection (wrist-guards) it was reminder of the potential hazards of Wheeling, during the couple days of down-time pondered if some larger pedals might have allowed a surer foothold & recover from that second of air-time. I've been lobbying for larger pedals with King Song for four years, but there wasn't much interest on the their end, citing that it would 'ruin the aesthetics' & 'not requested from other Distributors'. After clocking a 1000 miles on the V10F, with the accumulated experience with this Wheel, it was evident, the significant advantages that would accrue from this comparatively small change. Undeterred I proposed that eWheels would fund the larger pedal project, the results of which can be seen below. Although only 20% larger than the original type—25cm vs 20cm—visually the new pedal simply dwarfs the original, Notice how the edges have been tapered, more oval than rectangular. These preproduction set were CNCd, the production version will using the same magnesium alloy as before, the profile does seem to be slightly thicker for greater strength & durability(?). One minor compliant, is that the grip tape pads the same as size as on the smaller 20cm pedal, would prefer that these extend to the outer edge of the pedal. The real substance of the XL is inside, the massive 1550Wh battery pack. To accommodate those extra cells, the cell depth has been raised to two cells in height, 7 cells across columns one & two, & 9 cells in column three—the pack is asymmetrical, with more cells on packed on the right side than the left. Unlike the 18L, where the pack is enclosed in a battery casing, in this sample, the battery structure is comparatively primitive, with a single layer of blue wrapping around the pack. A concern could be that the outer shell body is now in contact with the pack, where if the Wheel receives a sufficient hard side-blow, it might place stresses on the nickel plates weld joints between the cells. Is this simply a characteristics of this prerelease prototype? Will there be silicon injection between cells, as there are in other packs, to transfer the physical stresses from the conductive plates? These questions should be answered next week. Here you can see the reinforcing 18L rib has been ground down to fit the fatter batter pack, presenting a challenge to existing Customers who might be considering upgrading to the 18XL. Another enhancement to the 18L is the new cleaner looking mud-guard, it's also made of a synthetic rubber that is screwed into the shell. I'll be posting an update with some further impressions sometime tomorrow, sorry, I ran out of time on this initial report.

    Why I Think The Nikola Is The Best Wheel At This Moment I’ve ridden it about 100-miles since Monday. I’ve taken on my first mountain test (picture above), climbing 5100-feet to ~11,000-feet. I’ve ridden it on tough rocky trails which demonstrated to me that it has superb low speed power (torque). First, if you have a MSX, KS18XL, etc., I’m not saying to necessarily run out and buy one. My commentary is for those of you who want to move up and have been torn as to which wheel to get. You can now safely skip the MSX, KS18XL, etc. The tire. It’s huge like the MSX. It’s wonderful like the MSX for dealing with crappy trails, roads, etc. But it’s a little bit smaller so you get better handling like a 16-inch wheel. I think this is the perfect size, between 16 & 18 inches. The tire is the main reason I say skip the KS18XL. The shell. It looks big (wide) but it’s an optical illusion because of the handle. But the shell actually has a nice taper away from the legs, unlike the MSX (which is more boxy). So it’s actually very comfy to ride and took me zero adjustment period like the Tesla, MSX, etc. The pedals. They don’t have the large dihedral angle like the MSX. Just your typical semi-flat angle. And they are huge. I did ride it through some snow (11,000-ft) and the ‘plastic grip tape’ does suck - slippery when wet 🙁 However, because your feet are lower compared to the MSX and the top of the shell isn’t ‘digging’ into your upper leg, The Nikola rides and handles like a dream. I don’t know of course until I ride one, but the 16X shell looks boxy like the MSX, where it hits your leg. Time will tell. Based on my rugged trail riding with the Nikola, it exhibits superb low speed power to slowly climb up and over very large rocks, etc. Going downhill also feels very secure. I have lots of wheels that I will continue to use for variety, etc., But I think The Nikola is now my wheel of choice for mountains, trails, long group rides, just about everything. And for you speed freaks, just buy the 100-volt version. Yes, there are negatives, but where it really counts (riding), The Nikola rules IMHO On a side note, I have now retired my ACM as the best all purpose wheel.

    As the guy who placed the first order for an 84V Nikola from @Jason McNeil and was riding one from the first batch, I was concerned when @Marty Backe reported the burnout of his control board. After seeing the pictures I parked the wheel until I could find the time to tear it down and inspect the control board (good to have other wheels to ride ). A long career in electronics design and manufacturing made me suspect that this was an assembly "innovation" not a one-off quality slip. Before disassembly my Nikola was riding flawlessly showing no signs of a problem. (By the way this wheel is WONDERFUL!) I had only put about 90 miles on the wheel before parking it. My rides were local rides on paved roads with rolling hills and max speeds of about 26 mph (42 kph). So... not much stress on this wheel. I have attached a picture of my control board that shows glue residue on the MOSFETs but no apparent thermal damage to the board or MOSFETs. As previously commented in this thread the presence of a substance that is a very efficient thermal INSULATOR on the MOSFET heat transfer surface is a big problem. I will be rebuilding the wheel on Monday after correcting the defect and bringing the thermal management up to what I consider an acceptable level. I will post a video of the rebuild for anyone interested in a DIY solution. So far when anyone has looked they found glue. Just another data point...

    News Directly From Gotway Gotway has reached out to me, acknowledging that they have seen my video and that they want to replace my control board. But here's the real kicker, and should be of interest to many. After telling me that a new board will be sent to me, on a separate line is this, "With big MOSFETs" So it appears that Gotway does have a new 84-volt control board design with what I assume is the TO-247 MOSFETs. Very exciting. They've heard us

    I was on my second 22-mile Tesla range test of the day (video tomorrow) when I ran into a divot in the path. In hindsight it seems like what happened to @Rehab1 just happened to me. I had checked my speed (via the Pebble) just moments before, so I know my speed was ~18-mph. The wheel wobbled for a split-second before I was thrown off. No time to take even a single partial step. BAM! I was immediately hitting the cement, and damn did it hurt. Took probably a couple of minutes before I could ever so slowly raise myself. Everything below my waist was a non-issue (thank you kneepads). My wrists are great (thank you Flexmeters). Unfortunately I have not been wearing elbow pads for a long time, thinking they don't really come into play much. Was I wrong. My leather jacket is toast (or at least now it's a dedicated riding jacket). As the picture below shows, my elbows is trashed. Tore some good amount of skin from my fingers. The helmet did it's job (see the heavy scratching. My riding glasses tore a bit of skin around my nose. But my right shoulder took a major impact. I'm hoping nothing is broken (no sharp pains), but it's swollen now and I don't have great movement. I'll add some additional thoughts later, but typing with one hand is a pain in the butt. Somehow the Pebble watch got a good scraping

    I have been busy over the last few days exploring the MOSFET thermal coupling issue on the Nikola. I put together a two part video that describes the current situation with the Nikolas and what I saw when inspecting my control board. It also documents a number of informal experiments that I did to test various thermal solutions using the Nikola heat sink, thermal pads and other thermal coupling solutions. The first video is available now and I should have the other done tomorrow that describes what seems to be a significant improvement over Gotway's standard assembly technique. Of course there may not actually be a need for better thermal performance and the bad units so far may have just been overzealous application of glue. I hope that these videos are useful to those of you that are considering your options on this issue.

    Out of the blue my wife approached me today and said she wants to see if she can learn. I'm rather amazed at this turn of events. She's not the athletic type and has felt she doesn't have the greatest balance (but rode bicycles as a kid). I tell her like I tell other people, that if you can ride a bicycle you can learn to ride an EUC. I guess seeing me ride all the time over the last couple of years has started to rub off on her. She says she'll never do the kind of riding that I do, but likes the idea of doing little rides together, maybe at some local parks. I think she just likes the idea of getting out of the house more, and some outdoors time with me I'm very excited, I just hope that she can pick it up. I'm going to take the training very slow, but fortunately she has me to teach her. Now I'm debating what wheel. I'm thinking for the very beginning baby steps I'll use the cheapo generic wheel. I would be holding her, etc. Then transition to another wheel. I'm leaning towards the Z10. If she actually sticks with it (a big if), then maybe get her Glide 3 / V8. Lots of time between now and then to figure that out. I'll keep you appraised of what happens here.

    Here is the second part of my video discussing the Gotway Nikola control board inspection and rebuild. This includes one more lab test and a detailed reassembly using thermal paste coupled with electrical insulation techniques. @Nils nailed it; I ended up publishing the director's cut. Most importantly, now that I have finished documenting this thermal issue and its solutions... I HAVE MY NIKOLA BACK.

    Hey guys, Another shameless promotion of my first ride with the 17" Gotway Nikola prototype!

    Went out for a night ride the day before yesterday. I've become very fond of riding at night, when the city is completely deserted. It's nice to be able to focus on my riding and on progressively taming the 18XL. I still struggle a bit with things like accelerating on wide curves (large roundabouts, for example), and get speed wobbles, wobbles when accelerating hard, and when braking (except power braking). I was out for a couple of hours, mostly practising hard acceleration, braking, carving and slaloming: I'm really starting to enjoy having to put my weight into it, it's very different from the V8, which I can just effortlessly "flick" from side to side. Also did some off-roading, which was great fun, as the paths I took are usually plagued with people walking their dogs, forcing me to limit my speed drastically. T'was fun to push the envelop and get high on the adrenaline Sidenote: @Marty Backe, I'm following your advice and using a flashlight for night-riding: the 18XL has a great headlight, but when accelerating, braking or on pitch black trails, it isn't enough. The flashlight works like a charm, and is a much simpler solution than the DIY inventions I tried to attach a bicycle light to the wheel or my helmet. I initially thought it would be tedious to be holding the flashlight all the time, but have grown used to it, and can easily turn it on or off depending on visibility, resting my arm. It also comes in handy when approaching an intersection: I put it on strobe mode to give drivers plenty of notice of my impending arrival before we cross paths, and so far, I'd say it's prevented several mishaps with cars ( @Smoother can attest to the fact those don't tend to end well...) Anyway, before I go off on another tangent, mid-ride I took a break, and realised I could have unlocked the max. speed to 50 km/h several weeks ago. So, I unlocked it (had to try 3 different versions of the KS app...but that's a different story) and started leaving my "speed comfort zone" so I can gradually overcome the wobbles (they tend to start at about 35 km/h). I noticed that I instinctively grip the wheel when accelerating hard and when I reach a certain speed, so I worked on relaxing my stance. Had a few close calls (the kind of nasty wobbles that make you consider bailing), but managed to control them. Then, on the last stretch before getting home, I pushed myself one last time, and....I was managing! Faster and faster, no wobbles, complete control of the wheel, feeling confident and....suddenly I'm airborne and sliding along the pavement. I was so focused on my riding and maintaining control of the wheel that I didn't even see the speed bump 100m (330 ft) from my house, which I ride past at least twice a day...I checked WheelLog, and since most the ride home was either off-road or accelerate-wobble-slow down, the trip's top speed (43,8 km/h) was, beyond a doubt, the speed I was going when I saluted the pavement. It happened so fast I didn't even have time to think. I landed on my right side, and based on the scrape marks on my elbow guards (and lack thereof on my wrist guard), it appears my right wrist didn't even touch the ground and all my weight landed on my elbow (perfect recipe for a nasty shoulder injury). I'm glad I was wearing sturdy skateboard-style protections and not something like G-Form Pro-X's under my clothes, 'cause even with the skid plate and thick padding, the ol' elbow was sore for a while. Aside from that, I had some tingling in my left fingers, which scraped against the pavement (might consider getting some leather gloves...don't fancy road-rash...) and a nasty hit on my lateral malleolus (bottom of the fibula). An odd place to take a hit...but a good argument for wearing high mountain boots when riding; loosely laced, to not hinder ankle movement, they do provide protection for a part of the body I'd never even considered might be affected in an EUC crash. I rode away from the crash a bit shaken and with tingling fingers, but that's about it. It was the next day when I found myself limping and with a fairly sore shoulder (not a nice feeling when you've already dislocated that shoulder twice in the past). Gearing up saved the day. Inspecting my gear later, my helmet doesn't have a single scratch, but if my head had hit the ground, it would have been from the ear downward, so anything but a full-face helmet would have been as good as nothing at all. Looks like my backpack absorbed part of the hit too, as there's a tear on the side (if it hadn't been for the backpack, that would have been my side scraping against the asphalt). Am no longer limping and my shoulder is only slightly sore, so I consider myself pretty lucky (I fell in a straight line; I could have landed on the curb, slid into a parked car, etc.). The 18XL got a couple of ugly scars, and I ripped the side pad in three different places (almost pulled it off entirely). The factory adhesive is strong stuff, just pressed on the pad for a few seconds and it stayed in place, so I reckon I'll order a replacement but leave it as is until it's beyond recovery. I can't help but remember some advice given by @Mono, I think it was, on inattention being one of the no. 1 causes of EUC crashes. I was almost home (which is when we tend to pay less attention), the streets were deserted, there were no pedestrians, cars, dogs or other "mobile hazards", and due to excess focus on keeping the wheel stable at speed, I wasn't paying enough attention to the road in front of me. In retrospect, I'm glad this happened late at night and the obstacle was a speed bump and not a person (although I wouldn't have pushed my limits like that in any other circumstance; then again...you never really know when/where someone might jump out in front of you...) On the other hand, since I moved recently, it took me a a while to locate and unbox my protective gear, so for a over a week, I'd been running errands on the wheel, on a daily basis, with no protections at all. Granted, I was extra cautious and didn't take any risks, but accidents can happen when you least expect it so...no more of that nonsense. If it hadn't been for protective gear, this would have been a nasty fall (although another small lesson I've learned is that no matter how much protection one wears, there's always going to be some part of the body that's unprotected, so I guess the risk of accidents and injuries is something one just has to accept the moment he hops on a one-wheeled fracture machine) Over and out

    Last updated: 13 May 2019 Dear fellow riders, as some of you may already know, I'm the guy responsible for latest WheelLog development This happened, however, during the development of the application to record the route together with the wheel parameters. This application (website) is now publicly and freely available to any of you here - https://euc.world - I named it "World of electric unicycles" I have chosen WheelLog as a base app that will source location & wheel data. I added some features that are very useful during your ride. In particular voice announcements and alarms. Really, you should try speed alerts! Wind noise will no longer be an issue to hear that you exceeded your preset speed. I also added other languages, thanks to @koto , @ArqFG, @andress, @George Iliev, @Lefteris and @fabio70mi. Currently WheelLog supports English, Polish, French, Spanish, Czech, Bulgarian, Greek and Italian languages. By the way, it turned out that more features could be added and improved, and that's how I - slightly unintentionally - became current WheelLog developer WORLD OF ELECTRIC UNICYCLES - DOCUMENT AND SHARE YOUR EUC RIDES Now the https://euc.world service is working quite good, so it's time to announce it's availability for the whole EUC community. Initially I've made it for myself, but soon realized that it may be very useful for other riders. It's my hobby project and it's completely free. It allows you to record your rides including your wheel live data. By default, saved routes are not visible to others. You can also share them with others by sending them a link. You can also make some routes available to everyone, so they will be visible on the main page. Euc.world is a great and free alternative to Endomondo or Strava, as it allows you to document your rides along with detailed wheel telemetry (wheel speed, battery charge, voltage, current, power etc.). You don't need WheelLog to be connected with your wheel to record your rides. In this case wheel data won't be recorded along your track - that's the only limitation. So if your wheel isn't supported yet, you can still map your rides. You can even add photos to your ride. I'll be happy to read your opinions, feedback and feature requests. Of course this website is still under development and now I'm working hard on wheel data visualisation. I think it will be finally working near the end of this week. Currently, wheel speed (black thin line) is overlayed on lcoation (GPS) speed. King Song users are advised to check if their wheel doesn't inflate the speed For example, KS-18L/XL inflates speed reading by about 20%. With time, I'll add more features and fix any bugs I'll be aware of. HOW TO START USING EUC.WORLD? If you already have installed WheelLog from Google Play store, uninstall it first. Download and install WheelLog from this link - https://euc.world/getwheellog Sing up with https://euc.world to create account and get your API key. Enter your API key into corresponding field in WheelLog live map settings in exact form. Small and large caps matters. Setup other WheelLog options according to your preferences. Start riding! Last, but not least - don't forget to give me some feedback so I can push this project in right direction. Note - you don't need euc.world account to just use newest WheelLog and benefit from other features. However I encourage you to at least try. If you think that you need some features, just let me know. I struggle to make this service fit EUCists nedds as much as possible. I'd kindly ask you for one thing... If you are going on an interesting route, think about making it visible to everyone. The idea that guided me when I created this website was to show other people interesting places where you can get on an electric unicycle. So if it doesn't affect your privacy, think about recording some routes in public mode. Add interesting photos, let others see the beauty of the places where you ride on one wheel. This is one of ways we can popularize EUCs. We can show that EUC riders are everywhere! And remember - you can also change visibility. Just log to your account, enter the tour you would like to edit and from "Tour" menu select desired visibility. So you can make the tour hidden or reverse - one of your beatutiful private tours make visible to everyone! WHEELLOG'S FUTURE WheelLog is a great application that's worth to maintain and improve. Now as I became a WheelLog active developer, I plan to add support for other wheels. WheelLog is lacking Ninebot support (wheels other than Z6/Z8/Z10). I already added support for Ninebot One S2 and plan to make other Ninebot wheels to be supported by WheelLog and I hope it will be done soon. Of course I also plan to add wheel sother than Ninebot. You can always find latest WheelLog version for download here: https://euc.world/getwheellog It will also be available in Google Play store soon, so installation and updating will be much easier. PLEASE, CONSIDER SUPPORTING MY EFFORTS As I wrote above, I plan to add more wheels (and other devices, like e-scooters etc.) to the WheelLog. I'll also review already supported wheels to check if I could add new features. It's my hobby. It's fun and pleasure so I can spare some limited amounts of my financial resources for WheelLog development and euc.world running, but only to pay for most important expenses. Any support from euc.world and/or WheelLog users will greatly help me with both euc.world and WheelLog development, especially in regard to adding new features and keep this application constantly developed. If you want to learn more, please visit https://euc.world/supportme Thank you in advance!

    So I've owned the 18xl for an entire month now. In those 31 days, I've learned a lot about this wheel. The power, distance on a charge, speed, and control are amazing on this wheel. I've already covered 1578km/980miles in the first 31 days. I use this as my primary mode of transportation, so this makes sense. I don't ride trails very often, just ride this to the store, to work, to church, or to meet up with friends. I do go for rides just to go for a ride, as I love the feeling. Distance is great, I can go to work, take an hour lunch, sometimes just riding around for that hour, back to the house that evening and still have a charge to go somewhere else and back home. I'm glad the top speed is 31mph as I'm able to use neighborhood roads and other roads that are not as full as traffic as much as possible to get around. I rarely go slower than 20mph. The last thing I need is cars passing me on a road because I'm holding up traffic. Instead, I can keep up with the normal flow of traffic and safely get to where I need to as if I were a bicycle or another vehicle. The control on this wheel is amazing. I've not had a single crash going fast on this wheel. The only time I've crashed was playing around on a walking trail and going around a muddy curve. The tire is so wide and the wheel is so steady that it just rolls right over any cracks, small potholes and such. Again, I use this on the streets only where I live so I'm not whipping it around, changing lanes or anything of that sort, I'm just riding it as if it were another vehicle in the flow of traffic. It stops quickly if needed, and it does such a good job of keeping you steady on the wheel. The original charger takes forever to charge it. I've plugged it in all night before and still haven't gotten it to a full charge. I'm thankful for the speed charger when I need a quick recharge to go back out. I try to use the original charger whenever possible and only use the speed charger when needed for a fast charge. Hopefully, I will preserve the battery life on this a little more by doing so. The pedals are huge! Which is great because I ride in whatever shoes I have on, wedges, flats, tennis shoes, boots or heels. I don't get as fatigued as I used to on my previous wheel which was a concern for me. I was afraid that the longer times on the wheel would just kill my feet lol. Glad it's not the case. I learned the hard way that you want to set it down with the mudflap up when not using it. The mudflap finally fell off this week. @Jason McNeil do you keep mudflaps in stock for the 18xl? Overall I really LOVE this wheel. I have been considering the Gotway Monster for the extra battery life. I'm not so sure I'll get it now. Maybe wait until KingSong makes an upgrade to an even longer lasting wheel. This wheel is super sturdy and easy to control. So glad I purchased it.

    No more rumors. Here's the real thing: https://youtu.be/ZhCCMtfBqSk Also, gotta give a huge thanks to @Jason McNeil from eWheels and Kingsong for allowing me to do a KS16X GIVEAWAY! Someone's going to win a $2000 wheel... TLDW: The Kingsong 16X is one of the best off-roading wheels and makes a solid city commuter. It's street performance is very solid, off-roading is amazing. The only drawback for speed freaks will be the top speed, 45kmh (28mph).

    My son Matt honored me with a birthday gift a few months before he died. Low on money he somehow found a copy of an old Rare Earth song 'City Life' that I really like and then recorded it on a CD for me to listen to in my truck. Best gift ever! Every time I play it I think of him. Matt went riding with me today with this song in my head so I decided to make a video. Love you always buddy!

    The First Mountain Stress Test A long video, but I have a couple of time markers early in the video if you just want to skip to where it crashes and burns I provide some of my observations in the video, but the biggest take away is the lack of low-speed torque. Under all but the most severe conditions the lack of torque is not noticeable. But when you throw in steep inclines it comes to the forefront. This is still an amazingly powerful wheel. As I say in the video, the Z10 makes me less impressed with the high voltage wheels, particularly what Gotway is doing. I'm not a power and/or motor engineer, but I think the Ninebot engineers are aptly demonstrating with the Z10 that with good engineering you can make a powerful wheel with relatively low voltages. Perhaps with Gotway, chasing the higher voltages is a cheap way to get the power if you don't have the engineering talent BTW, Jason (EWheels) gave me explicit permission to try and over-stress the Z10. I wouldn't do this to your wheel if you loaned me one, promise

    Ok, some words to the rumours of "massive Motor" Problems. There are None! Because of a partly different Motor of the 16X the 5 Pre-Production to the 2 prototypes the wheels had that "oscillation" when going over 40kmh. This is allready fixed by a Firmware update last Weekend! The production of the 16X will, nonetheless, be a Little bit delayed ….and unfortunatly be produced only in Mid July. The reason for this delay is in the massive Feedback, received from the test of the pre-production models and asking for some changes! That are small parts done better for better waterproofing, another pedal angle and other small and very minor details, but also a Hardware-Change on the Motherboard. KingSong wants to deliver a flawless 16X to it's customers, so the extra time added might be annoying...but in the end this is all for our own best!

    You're right. It also seems that there is no temperature probe near the radiator or MOSFETs. This is a major design flaw, as PCB temperature where temp probe is apparently located in Nikola, being additionally cooled by the fan located on wrong side, doesn't reflect MOSFET tab or package temperature. This is why @Marty Backe got misleading, very low temperature readings. For example, in KS-18L/XL there is a temperature probe located close to the heatsink and MOSFET that is farthest from the cooling fan. This is why L/XL may be perceived as a "hot running wheel". Nikola wasn't "cold running wheel", it was just a "very hot running wheel with low temp readings". From what I see, PCB design may cause MOSFET source (S) leg to overheat, as there is highest thermal resistance due to small copper pad directly under the MOSFET leg. I don't see the other side, but i assume it's similar so drain (D) legs are also connected using small pad located on an edge of larger copper plane. Another design flaw is to use two TO-220 MOSFET instead of one TO-247. Doubled small package design is prone to many failures. MOSFET leg fracture during bending or PCB assembly will increase leg resistance. Improper soldering or improper PCB design may cause current imbalance, so it wont be divided 50/50 between both transistors. And if one MOSFET will fail, but won't short, second MOSFET failure is a matter of short time, as it takes over full current instead of part of it. As we can see in the photo, it was the case. Failed both MOSFETs on one side of a motor phase half-bridge circuit. Double MOSFET design may work well only if is properly oversided, so each single MOSFET is able to carry maximum current expected to flow in the motor phase circuit. But as failing MOSFET will likely create a short circuit, secondary MOSFET won't be beneficial.

    This was the most beautiful EUC route I have ridden so far. Six electric unicyclists @Marty Backe, @Jrkline "Wheel Whisperer", @Rama Douglas, @mark chanya, @Tanabe, and myself rode 58 miles across the San Gabriel Mountains with a recharge at Mount Baldy, CA. Wheels in attendance were two Gotway 100v Monsters, one Gotway 84v Monster, two Gotway MSX, and a Kingsong 18XL

    I know this will come as a surprise to some of you, but I'm burned out on Gotway. Their perpetual sloppiness in manufacturing and non-responsiveness to community feedback has finally convinced me that KingSong is the only way to go from here on out. Fortunately I have the KS14S and KS18XL. I'm going to buy two KS16X's and will outfit one of them with a knobby tire. This will allow be to sell my two ACM2's (what a relief to finally dump these turds). Hoping that 2019 will be the year that KingSong releases a Monster killer, then I can get rid of the Monster too. I'll probably keep my remaining Gotway wheels, mostly to loan out to visiting riders from out of town. Sorry to disappoint my fellow Gotway wheel owners, but I have to be honest to the community.

    Hi 👋 🤗 Thank you all so much🙏🏻. I want to say a big Hello from riders from Vladivostok👋 I do not speak English and will use a translator, so I apologize in advance if the translation does not sound very correct🙏🏻🙏🏻🙏🏻Thank you for inviting me. This is unexpected. I am very happy to meet many friends here. When I bought my first wheel, I had a lot of questions. I didn't have anyone to ask. In Vladivostok such monowheels were not. It's great that there is such an opportunity to communicate between people. Thank you very, very much.😊🌸🌺🌼

    Overheat Hill Smokes My Nikola I just returned from my mountain stress testing of the Nikola and it utterly failed (nothing like the smell of burnt MOSFETs in the morning). So I owe all you guys an apology for defending Gotway's decision to revert back to the smaller MOSFETs. What can I say? It's still a beautiful wheel, and as you'll see, it does have amazing low-end torque and was running cooler than any other wheel other than the MCM5. But it looks like the electronics aren't up to the task. So if you have a Nikola or are thinking of getting one, don't ride it in tough high-ampere conditions. Note that my 5100-ft climb to 10,500-feet was a non-issue. So I think most riding conditions will be fine. But if you live in San Francisco, etc., be cautious and monitor your power consumption.

    There is a development update to report; they will be using a new 2200W motor, using a different PWM waveform, to try to match the silent & instant responsiveness of the Gotway controller. Tina says this is not expected to delay the production, currently still on target for next month, however, the demo Wheel is delayed until month's end now.

    Impressions After 3-Days & 90-Miles I love this wheel Focusing on the negatives first, the wheel clearly is lacking in low-speed torque (I don't know if there's such a thing as high-speed torque). This only manifests itself when you are climbing a steep incline, slowly. In the vast majority of my time riding this wheel I have never felt the wheel to be lacking in torque, power, speed, etc. So yes, I will not be grabbing this wheel when I anticipate doing some steep climbing. Most of the real steep climbing that I do is during testing or when I feel like experimenting when out and about. So in my opinion the lack of low-speed torque is a niche issue. But it's there for sure. Once I settled on ~35-psi for the tire pressure, the wheel has performed just as I would have hoped, It has superb traction that matches any other wheel I have. The ride is not too hard - feels like my other wheels (I like a firmer ride). Tracking also matches my other wheels. It purrs when encountering sand pockets. I recently turned off brake assist and I feel like the traction going down steep inclines is better. I will know more when I take it to the mountain proving grounds for round two. This wheel is a blast to ride as I experienced a little of everything today in my 38-mile range test. I absolutely love the low-speed handing. Considering the massive tire on this wheel, the Z10 feels closer to a 16-inch wheel. It feels closer to my ACM than the MSuper. Doing tight 360's and backward spins on this wheel is a real joy. Nothing like the more cumbersome MSuper and much more relaxing than the twitchy Tesla (or even ACM). It really does remind me most of the Mten3 in terms of low-speed handling. I am really stoked that I'm going to own one of these in the next month or two (hopefully with a working sound system). Again, except for the torque issues that occur in niche conditions, the Z10 feels like a very high performance wheel, but one made in Germany instead of China (I hope that analogy translates well).

    It's Kuji here. I used to roll with the guys in SF, but moved to China about a year ago to work with Ninebot to follow my passion. I'm an entrepreneur who is just obsessed with self balancing vehicles. Things at Ninebot didnt pan out as i had hoped, but my obsession with electric unicycles hasn't been fazed. I figured id show off my first piece of work on reviewing the new inmotion v10F. I dont have any background making films, but I figured id give it a shot and start making videos about self balancing vehicles, electric things, and seeing where this takes me. It's less than 5 minutes long, super dense, hopefully entertaining and funny. It covers about 80% of what I feel about the V10F after riding over 500km on it. I figured id post it in 'general discussions' rather than specifically in the inmotion category since i think this video would appeal to all electric wheel riders. Since this is my first video, it would be SUPER appreciated if you 'subscribed' to my channel... More to come! I hope you guys like it! Here's the video:

    Another excellent write-up by @EcoDrift (via Google Translate) regarding all the QC issue of recent Ninebot One Z manufacturing (including references to our very own North American superdealer @Jason McNeil ) https://ecodrift.ru/2019/02/12/ninebot-z10-chastaya-polomka/ Ninebot Z10. One of the frequent breakdowns. I tried to collect material on the pre-sale preparation and maintenance of the monowheels. But my attention was attracted by the open Ninebot Z10. He asked what happened to him, but it turned out that this is a sad whole story, which I will tell you today. After the start of sales, Ninebot Z-series monowheels unexpectedly turned out to be leaders in the number of warranty calls. Wheels directly out of the box often do not turn on, as the battery protection works. Our very first wheel didn’t turn on that way. But I came across a wheel with another problem. It clearly looks like a Facebook user (click). The wheel walks back and forth and does not really hold the horizon. I just caught the wheel disassembled: The following problem is visible on the controller: Contacts burned at current sensors: What have two. These current sensors are Hall effect and they are designed for a very high current. Such sensors (designed for high current) were detected only in Ninebot (in Gotway, sensors are connected via current-lowering resistors and have much more modest parameters). Service engineers immediately said that this is a frequent problem of the Z-series. And for example, dragged another Z10, whose contact burned down only on one sensor: You can see that the sensor on the left side feels fine: The guys from the service center tried to restore the burnt track on this wheel. After that, the wheel goes normally, but if it is on it try to drive into a small curb from the spot and everything repeats. The problem can be anywhere, but the simplest thing is to just take a new controller. Rather, the board with the power part: To check how much this “repair” really helps, I decided to check with our American colleague Jason McNeil. He is the owner of the portal eWheels.com and has sold quite a lot of Z-series monowheels. Jason confirmed that it is enough to replace one lower board and the problem does not recur. The same sensors on the new board: The reverse side of the new board (the controller is diluted on an aluminum substrate): So the repair is very simple. Disconnect all wires. Remove the fee: Thermal grease on the old board: We connect new, we connect everything back: And the wheel works great: But I decided to ask Jason about the situation with the Z-series: how often they break and how many of them have a marriage. Jason was very emotional, because from Z10 he decently boiling. Jason wants to sue Ninebot for non-compliance with its obligations and for the poor quality of the Z-series. Marriage was abound. As a percentage, this is at least 20% of all devices sold. The problem of current sensors can lead to melted wires of the phases and even burnout of the controller. And of course, enough battery problems. As a result, Jason's opinion about the Z-series in particular, and Ninebot in general, is just a piece of garbage. Sheer frustration. For the comfort of users, it remains only to add that the overwhelming majority of problems arise at the start of operation. Approximately the first 50km and a pair of first charge cycles. If the wheel has passed the initial stage, the probability decreases to very low.

    So, I had planned to open my wheel some time later, but went shopping today for some materials to prepare for later. Having some prerequisites at home it turned out that I couldn't live with the suspense any longer though, so I rolled up my sleeves and opened the wheel up. After a rough fight with silicon I freed up the board enough so that I could somewhat inspect the MOSFETs without taking apart the board. Everything looked clean, and I couldn't see any traces of glue anywhere. My wheel has performed well even when I've purposefully loaded it, so I already knew it wasn't a lemon, and the first inspection seemed to reflect this. However, you can't really see that much from the outside though, and there could still be glue hiding under the thermal pads which would be impossible to determine from the outside. Hence I proceeded with disconnecting the board and after besting the silicon foe again I disassembled it (a pox on anyone putting silicon in screw heads!) . I suck at documenting stuff well apparently but here's a picture of my MOSFETs with the inner row thermal pad removed: It was completely clean for all practical purposes. Only the MOSFET to the left had some glue/stuff on it's sides, but nothing covering the pad. The two MOSFETs to the right might look a bit weird in the photo, but those are discolorations and not anything do to with any adhesive. While not shown in the photo, the outer row of MOSFETs was completely clean as well. I fitted new thermal pads and reassembled the board, which was finicky but not super hard (heat sink at the bottom, place thermal pads with ready made holes in their correct positions, fit the board looking through the MOSFET screw holes, keep pressure on the board and insert screws for the middle row. The outer thermal pad can be adjusted if needed easily enough). In conclusion, not all Nikola boards are glued it would seem. I have a very early version for what it's worth, product code indicates it was assembled on April the 2nd. This would seem to lend some credibility to the theory that only certain wheels have been assembled badly. I believe that my wheel is a very early one, and that for instance @Marty Backe's is a later one. If so, that would suggest that it's not a case of any early process being improved on shortly after but crappy assembly for certain wheels. Anyway, after reassembling the wheel I went for a ride, and a great one it was! My Nikola is now open for business again!

    Apologies for the late attendance to the party. Since receiving a 2nd board failure (this case was different, it was powered on from a stand still & didn't respond), including Marty's, within two weeks of shipping out the first batch of Nikolas, I've reached out to Linnea on Thursday to try to come up with an action plan to see what options are available to greatly reduce/eliminate the risk of these MOSFET thermal overload events. The evidence from both of these failures has marked similarity in outcome (see below), where this glue may be acting as a thermal barrier, not helped by the absence of thermal paste on the underside of the metal heat transfer surface. One option being explored, is to recall the boards. remove this glue, & apply the thermal paste. To date Gotway have shipped 600 units; they say they have not received reports from other regions of this failure—it's likely more will trickle in in time. Putting out an official recall is not something to be taken lightly; in their defense, they're probably looking for a few other reports, before taking this step. Gotway have a lot of experience with building high power motor vehicles; they had gone through several rough patches, particularly with reliability of earlier generation boards, with the weaker MOSFETS, but at least then they were pretty consistent with applying liberal quantities of thermal paste to this underside. It was baffling to me why they would go back to an inferior TO22x FET package AND now we learn about the lack of thermal paste. From my experience, such oversights are usually not the result of penny-pinching, but execution on the production line, where the factory needs a ruthless eagle-eyed floor manager, to see that every step of assembly is done by the book. The silver-lining to all this, is that an early finding in the production cycle is a necessary facet to a small-scale non-ISO production facility, where the manufacturer's financial pain of having to deal with a crisis, means that they will be imbued with a sense that this situation must never occur again. For all current Nikola owners, please hang in there, we should have an action plan in the next few days. EDIT: To anticipate questions on the 100V Nikolas, they are using the TO247 MOSFET package, the first production of these special edition 1845Wh variants is still underway, there is assurance that in light of this episode, they will getting the thermal paste treatment!

    Good guess! But no. The champion of the 2019 Electric Unicycle Grand Prix held in Oakland, Calif. on Saturday is Freeman Murray, riding with unmatched skill and speed on a Kingsong 18L. Freeman was able to consistently carry the most speed through the slalom and was the fastest rider all day. We ran heats of five laps around the course, expertly and generously organized by @Kai Sosceles, to whom we all owe a debt of gratitude. Freeman ran a 2:57.76 in the five-racer final to take home the title and a $250 cash prize. Little old me had to push my MSuperX as far as I could to finish less than three seconds behind Freeman in second place with a time of 3:00.65. It was a pleasure to buy a post-race round for some of my fellow racers with the $150 I took home for second. Third place (a Kingsong 18XL) got $100 and was just two seconds behind me, so I needed every bit of everything I had. The winning and prizes was very cool, but the most important part of Saturday was 1) it was 100-percent safe, with zero injuries or serious crashes and 2) amazing fun for all. All riders rode within the capabilities of themselves and their equipment, and everybody shared a special moment highlighting all the best things about our weird little hobby. I'll put up a few videos here, I'm sure there will be more to come as everyone processes their work. But I'll share my favorite quick story from the whole event: About 90 minutes in, during a break in the racing, an East Bay Municipal Park District police officer pulls into the parking lot. Walks up to us, friendly but serious. Kai explains what we were up to, and then the officer tells us that electric vehicles are not allowed on part of our course (the back stretch, a shared bike path). He told us he was going to check some regulations in his car, so we waited. As we wait, another officer pulls up, and we're thinking we're shut down for sure. After a few minutes of discussion, the officer walks back over. He tells us: "So, we had some busybody, umm, citizen, call in and report you guys, because they weren't having as much fun as you were. And, we're going to leave now." And they did! He smiled, went back to his car, and they drove off. We finished the final heats after the tacit approval of some very cool cops! Final heat, raw 360-degree video:

    @Liamfind, it's always great to see some involvement at the Manufacturer level. Before moving onto a new product, I think Inmotion should first focus on improving the V10/V10F to make it a Best-of-Class product that it deserves; it's 95% of the way there for hardware, but needs some inexpensive tweaks, that your Customers have been requesting for months. Both King Song & Gotway have been pretty good with Continual Model Improvement, but we haven't seen much of this practice at Inmotion. Handle Play: the external handle mount is fine, keeps the internal space available for the ~1kWh battery, but the 5cm of play in the handle, going all the way back to the V5F days (more than 2 years ago), is completely necessary & is a real problem with a 20kg Wheel. The folding hinge joint needs to be retooled with smaller tolerances to eliminate this play. Reducing Speed Throttle at <70% SOC: a battery of ~1kWh provides plenty of surplus power all the way down to 3.2-3.3v, a chief compliant among V10 Customers is that while it's great to have 40kph cruising speed, this performance is available for only 30% of the total capacity of the pack. It seems the Engineers have not taken into account the capabilities of the hardware in the V10/F for programming the throttling levels. On machines like the Gotway Tesla, other manufacturers have demonstrated that it is possible to provide Customers with longer high speed cruising duration, without sacrificing safety. Controller Performance: Gotway have introduced the HY MOSFETS with the TO-247 packaging, which has a huge heatsink. The empirical evidence from veteran Riders, like @Marty Backe, is that these boards are almost completely immune to over-heating & have an incredibly high reliability rate. The V10/F is one of the most susceptible machines to overheating, this greatly limits it's utility for hill climbing & operation in environments with high ambient temperatures. Waterproofing: no doubt you're aware of the deficiencies in this area on the early V10Fs & the toll it took to the reputation of the product & cost to the distributors performing the recall. Any details you can share on what improvements have been made at both the organizational level & technical changes to prevent this from ever occurring again would help to restore some trust in the Company. Sensible Spare Parts Pricing: as a Dealer, charging nearly $200 for a replacement controller makes it extremely difficult to offer onsite spare parts service for Customers. While many of the parts prices are inline with what other suppliers charge, there needs to be some rationalization for certain parts.

    I have great news for all. I didn't expect this, but @Jason McNeil of ewheels.com contacted me and suggested that I continue maintaining WheelLog, in turn he offered to me access to Kevin Cooper's account in the Play Market, with the possibility of publishing WheelLog. Thus, all subsequent WheelLog updates will be distributed through the Play Market. Thanks Jason ( @Jason McNeil), thanks Kevin ( @JumpMaster), it was really surprising. 2.0.16: - Fixed reconnection to Ninebot Z, and some more bugs with it. 2.0.17: - Added GPS speed, heading, altitude to logs (now you are able to see how GPS far from reality, or.. ) 2.0.18: - Added Solowheel Glide 3 support 2.0.19: - Roll back of battery percents to official formulas (I'll return to this question when I figure out how to do it better) You can find new version in Play Market. Source code was updated: https://github.com/palachzzz/WheelLogAndroid

    Just had a wipe-out, second day on the 18L—it's the third 18L in existence (one of the prototypes)—with the power on during shipping incident & swapping out the board. Circumstances: I was bombing along at max speed 40kph, an unmarked speed bump maliciously popped out of in front of me. Had 2 seconds of air time, classic hands-in-front to save myself posture, wrist-guards saved my bacon, very minor knee scrape, otherwise pretty good shape. I know it's a debatable topic, but I'm so glad we've been shipping wrist-guards with all the Wheels, knowing that at least one part of your anatomy is impervious to danger & can take the brunt of the impact, can really make a difference in outcomes.

    OK. Hats off to @eddiemoy. I believe he has identified to root cause of my failure - crappy Gotway workmanship (or whoever builds their boards - do we know?). I took a high resolution photograph (click if you want to access the full-res version) of the MOSFETs in question and the thermal barrier. You can clearly see a bit of the plastic still stuck on the sheet. I closely inspected both thermal sheets and they look clean except for this section. So whomever assembled this board, nonchalantly pealed off the backing material and shrugged their shoulders when some of it tore and stuck to the thermal sheet. It's so obvious now. Those three MOSFETs could not dissipate the heat and blew. This makes me feel better that probably most of the Nilola boards are OK, but unfortunately it's now a bit of a roll-of-the-dice if a Nikola owner gets a crap board. And it's basically impossible to inspect the board without destroying it to gain access If this was not a second rate Chinese company, they would do a recall out of an abundance of caution and replace the boards with fully inspected ones. But we know that's not going to happen. I'm tagging @Jason McNeil so that he sees the root cause. Thanks again @eddiemoy, @Rehab1 and @Jon Stern
