  1. I modded my MCM5 to ride on Chao Yang 14x2.5" wide tire. The stock MCM5 is 14x2.125" wide. I am used to wider tires (mten3, Z10, Nikola). I was not comfortable with the stock MCM5 tire. @RoCan modded his MCM5 for the 2.5" wide tire. This tire mod require cutting away a portion of the front and back shell cover along with the outer edges of the wheel well. I took @RoCan advice and made sure I cut away enough material so there is ample clearance for the wide tire. The clearance I was shooting for was 3" from edge to edge. This means the last two bottom shell screw holes were cut off. I plan to use metal or moldable plastic tabs to hold the cover bottom edges to the shell. The plan was to do rudimentary cut, install tire, and ride test. Then clean the cuts, seal any gaps, and trim out. Currently at the ride testing phase. Initial observations: The 14x2.5" tire is actually 14.5" diameter. The recommended pressure is 35-45 psi. The tire need to be inflated at or above 33 psi. Anything less and the tire rubs against the top inner wheel well. I believe under inflation causes the tire to expand diameter wise. Whereas higher psi the tire widens (flatten). I am testing it at 43psi which is on the hard side. I feel it going over 4" curve. I plan to reduce the tire pressure in 2 psi increment to find the lowest useable pressure. I took the wheel to work. The ride quality even with hard tire pressure is fantastic. The combination of wider tire and the tire itself gives the wheel very good control. The feeling of falling over on tight turns is gone. It handles like an mten3 at low speed. At higher speed (22+ mph) it gets a little squirrelly due to high tire pressure tracking road. I believe this can be resolved by dropping the pressure below 38 psi. I am glad I did this mod. It has turned my MCM5 into a mini Nikola. Chao Yang 14x2.5" tire versus stock 14x2.125" tire.
  2. The topic of tyre swapping and alternatives comes up more frequently these days. So I cut this from another thread. It's a tiny bit messy, but a lot of questions are answered by the data. Here's what my research has pulled up. Most of us know by now that bicycle tyres/tires are specified by the total diameter of the tyre, not the rim it fits on, as per the rest of the tyre world. So for example a 14" EUC actually has a 10" rim. However things get complicated with machines like the Gotway Nikola which is a 17" wheel, not because the rim is bigger, but because the tyre on it is actually just a fat 16" that measures 17" across. To be clear, it still fits on a standard 16" EUC rim (except maybe the rime is thicker from left to right, I don't know, Ecodrift measured the motor windings of the Nikola at 3cm, but I just measured the motor winding on my 3 year old KS14C. Guess what! 3cm. But I have it on good authority the manufacturers do not has the same motor suppliers) Right, so, here's the skinny: Most tyres have the actual rim size and width (distance between the rims across the tyre from side to side, often wider than the rim) in mm, stamped on the sidewall So: If you want a tyre for your 14" wheel look for a tyre with yy-254 where "yy" equals the width (yy details below) e.g.47-254, 57-254, 64-254, 76-254 and 254 = a 10" rim If you want a tyre for your 16" wheel look for a tyre with yy-305 e.g. 57-305, 64-305, 76-305. 305 = a 12"rim If you want a tyre for your 18" wheel look for a tyre with yy-355 e.g. 64-355, 76-355. 355 = a 14" rim If you want a tyre for your 22" wheel look for a tyre with yy-489 e.g. 64-489, 76-489. 489 = a 19.25"rim (not sure if that exists) So in theory even a 17" tyre will display 305 on the sidewall, because the size of the rim hasn't changed. "yy" chart 47mm = 1.75" 57mm = 2.125" 64mm = 2.5" (actually its 63.5mm but my 2.5" tyre says 64, so I assume they all round up) 76 or 77 = 3" For example, If you're looking for a tyre for your 16" wheel anything with a secondary sizing designation of yy-305 will fit. However too skinny or too fat could cause problems, both with your rim fitment, and possibly the area in the wheel cavity within the EUC itself. I hope this helps, and remember, my advice is worth what you paid for it, so verify my finding before plunking down your Sheckles for a shiny new tyre from across the seas. And don't forget to consider your inner tube issues.
  3. EDIT: As promised I added two more tires to the comparison – 5. Chao Yang H-5167 and 6. CST E-Bike PRO. You can find the description, video, scores and final conclusion below. As some of you may know from my first post in Inmotion thread, I have recently bought my first wheel - Inmotion V5F+. After learning how to ride the wheel, I started using it for daily commute to work and going around the city. I am absolutely thrilled by the wheel, but after few hundred kilometers and some strange and unexpected behaviour I started to doubt the tire that came with it. Therefore I bought 3 other 14 inch tires and made this little comparison that I would like to share with all that might be interested and could find it useful: DESCRIPTION: 1. Hota Tyre Slick, soft rubber tire, with very simple and shallow tread. This was the tire that came with my wheel and quite soon after learning to ride I became suspicious that this might not be very good tire. It could be a good tire but only for asphalt without any surface imperfections. Pros: very manoeuvrable and has a really good grip on good asphalt surface. Not bumpy when jumping down from reasonable heights. Low roll resistance. Cons: it REALY (!) likes to misbehave when you have any vertical lines or deformations along your route, you are immediately “railed”. This might be because when it warms up it gets “mushy” and the slick surface probably seeps into the deformations on the road. Uncomfortable when bumping into curbs. Before I tried other tires I thought that I maybe don't know how to handle the curbs because my knees sometimes hurt after longer rides. Now I know that is not the case because I never experienced this with other tires. For some reason this tire was also unable to hold the pressure above 40psi. I would pump it to 45psi and after few kilometers it would be back to 40. I used the same inner tube on all tires I tested. 2. CST Rhino King This is new model from CST with “puncture protection” and the most expensive electric bike tire I could find on Alibaba/Aliexpress/Taobao, so I thought it might be good. It is by far the most hard / rigid tire of the whole bunch, with relatively complex and very pronounced tread. This would be a very good tire if not for one fatal flaw. Pros: Stable during straight riding, good grip both on asphalt and gravel, quite comfortable when bumping into curbs, has puncture protection. Cons: Well this tire has one fatal combination for the EUC – it is very hard and it has such a steep fall-off on the tread that it is almost unreasonably difficult to control during leaning left or right. When you ride straight with only small left or right course changes it is perfect, but when you need to make any little bit more aggressive turn or lean into one side, you really have to work to keep the wheel from falling down :-( 3. Schwalbe Big Apple So called “balloon” tire, from well known Schwalbe brand. Simple and shallow but dense tread on soft and almost slick rubber surface. This tire has different construction from the other tires, with soft, paper thin side walls from different material (think its kevlar reinforced?) and is very deformable when not inflated. Many sources say that it has to be inflated to minimum of 55psi when used on EUC or otherwise you risk damage to the side walls, so I tested it both on 45psi (like other tires) and on 55psi. This is the only tire with slightly lower width – 14x2.0 (others are 14x2.125) Pros: Best tire for bumping into curbs and amortising any kind of bumps, especially when inflated to 45psi, but even on 55psi it’s still the best in this regard. Very good grip on asphalt. Relatively good directional stability, especially considering the shallow tread and soft surface. Low rolling resistance. Cons: Bit bumpy when jumping down from curbs, not the best grip on gravel. There is also potential damage to side walls (as reported by dmethwin on Firewheel thread). I travelled 80km on this tire and even after this low mileage there was some black dusty “residue” coming off the side walls when I dismounted the tire from the wheel. Not certain how this would influence safety in the long run. 4. Chao Yang H-5146 Tire from harder rubber, but not like CST Rhino King, about half as hard. Pronounced and complex tread. Pros: Most stable tire of all tested on any surface, it just goes where you want it to go without any unexpected surprises. Inmotion V5F+ is a very agile small wheel, which sometimes represented a challenge for relatively inexperienced driver like me (total of 800km in 45 days) when faced with nasty road anomalies , but this tire gives it another dimension in stability without compromising manoeuvrability! Very good directional stability and handling of vertical anomalies on the asphalt surfaces. Good grip both on asphalt and gravel. Cons: Could be better when bumping into curbs, but this is not a real con, only wishful thinking after being spoiled by bump amortisation performance of the Schwalbe Big Apple, which is the only tire out of the tested ones that is better in this regard. This tire has quite pronounced grip and therefore two slick tires have a little bit lower rolling resistance. 5. Chao Yang H-5167 Medium soft tire with added puncture protection layer. Very complex and relatively pronounced tread. Pros: This tire forced me to rethink the score table. I expected something quite similar to Chao Yang H-5146 just with added puncture protection, and although these two tires share many good characteristics, this is in some aspects entirely different beast. In one word – SPEED – this thing rolls like crazy, I was actually convinced that my V5F+ somehow restored to the lower speed limit after the tire change because I have never before reached 25km/h speed limit and tiltback so easily. And the best thing is that it manages to maintain almost all of that wonderful control and stability that H-5146 exhibits. Great handling of anomalies on the road, good impact absorption when bumping into curbs, not bumpy while jumping… and on top all of that it has additional puncture protection layer. Cons: Slightly less (5-10%) controllable than H-5146, probably due to crazy good rolling resistance 6. CST E-Bike Pro If I am not mistaken, this is the tire that usually comes with Kingsong and Gotway wheels (although I can't say how it behaves in sizes other than 14 inch !). Medium soft rubber, pronounced tread. I just had to test at least one more CST tire to have something from another serious manufacturer as a reference to compare to the two Chao-Yang’s. This tire is made of different rubber compound, it’s not super soft but it sticks like crazy, reminds me of the winter car tires. It is also the only one of the tested tires that screeches on the glossy surfaces like marble tiles and those surfaces in shopping mall garages. Pros: Good rolling resistance, great grip on asphalt and good on gravel, fabulous handling of curbs and jumps (very close to Schwalbe Big Abble, and that is a balloon tire -could be that rubber compound?) Cons: Slightly sharper fall-off from the center of the tread to the sides – not nearly as unusable like on the CST Rhino King, but you can still feel it, especially when compared to the Chao-Yang’s. This makes it bit less controllable and sometimes “jerky”. Although it has good grip on the gravel, you have to work more due to that fall-off to keep it under control when wheel bumps around on the uneven surface. I am probably just spoiled by Chao-Yangs by now… VISUAL COMPARISON: SCORE: Tire brand / type Hota Tyre CST Rhino King Schwalbe Big Apple Chao Yang H-5146 Chao Yang H-5167 CST E-Bike Pro Size 14x2.125 14x2.125 14x2.00 14x2.125 14x2.125 14x2.125 Ride Comfort 8 8 10 10 10 10 Control 10 2 9 10 9 7 Grip Asphalt 10 8 8 10 10 10 Grip Gravel 4 8 6 8 8 8 Impact absorption 5 8 10 9 9 10 Directional stability 2 10 8 10 10 10 Temperature stability 4 10 10 10 10 10 Rolling resistance 9 8 10 8 10 9 TOTAL: 52 62 71 75 76 74 I am not expert on tires and all of the above are only my personal impressions and conclusions after using these tires on my EUC. All of the tires are tested on the same Inmotion V5F+ and with the same inner tube (Tube brand is Chao Yang). I tried each of the tires for at least 80km. CONCLUSION: Chao-Yang H-5167 is the tire that stays on my wheel. It’s simply best overall and checks practically all important “boxes”. H-5146 would be best beginners tire, it’s so controllable, relaxed and forgiving. Both CST tires have great rubber compound, but the tread has this pronounced center section and then somewhat steep fall-off, which results in less smooth experience and requires more work to control the wheel.
  4. Hi everyone, I just got my first euc, a ninebot one e+. The tire came with a low pressure so I tried to inflate it following the comment on this forum. The problem is I can't get any pressure reading while I am still able to inflate the tire. I first try to connect the valve with the brass adapter to a schwin bike pump and connecting everything didn't even move the needle on the gauge. I change my pump to a bell bike pump and got the same result, finally I got another flexible extension instead of the oem brass extension and again same results. In all 3 cases the tire got inflated, I just can't get the actual pressure measurement. I am just wondering if anyone encountered this type of issue before and if they were able to overcome it. Thank you very much in advance. Simon

  6. Hey all, nabbed a Z10 back in October and have been happily shortcutting urban transportation since. I recently checked the app and realized I've put 1000 miles on the wheel! I thought I'd ask if there is anything I should think about tuning up or checking out after this much mileage. The wheel is working great, and I'd love to make sure it stays that way. Any tips or advice?
  7. Hello guys, hope youre having awesome days with your wheels!❤️ I recieved my new lovely 18XL last week and I completely forgot to check the tire pressure...(ridden around 60km so far and I love it!) My BW is 80Kg, I am 180cm... How many PSI / BAR should I use? Thank you very much guys, have a great day!
  8. (16/03/2019 updates in progress) Hello After more than a year working on my blog about the Mini, I decided a few days ago to monetize my blog, it reached more than 11,400 visitors from 115 countries. By joining affiliate programs with resellers, I choose spare parts and accessories for the Mini. I try to pay attention to quality even if it is difficult. I would touch a small percentage of a sale made, which will perhaps allow me to improve my blog, will see, I start with these programs. https://mini-j.jimdo.com/shop-guide/ It is therefore in total transparency that I announce the creation of a new site attached to my blog, called "Mini-J-S-G" (for the entire title: mini-j shopping guide) (cancelling) jojo33
  9. Hi there! 35 psi still feels soft for my weight. I wonder if it is safe to put bit more air into Z10? Did anyone tried pressure over 35psi?
  10. I'd like to know how many other 16" EUC riders here have experience with the Maxxix Hookworm 16" street tire. https://www.amazon.com/Maxxis-Hookworm-BMX-Tire-16X1-95/dp/B00188A1LG After recently switching over I can safely say that this will be my tire of choice for my KS16S. I thought the wheel was nimble before but this has brought it to a whole new level. It allows me to make sharp turns and carve like I never thought possible. One downside is that it can make the wheel a bit more prone to wobbles but no big deal. Couldn't recommend higher for all experienced riders of 16" wheels
  11. Hi, I'd first like to start off saying I don't have any real experience modifying a tire and since I only have the one to mess with and there are not any other options on the market I am looking for help from those here on the forum. Timeline: I need this done asap, but can extend my duration to as far as wednesday next week. The wheel: It's a 10x2.5 Dualtron 2 EX tire. I've had tons of problems with. Today I had my 9th flat in 7 weeks. My current idea is to reinforce the tire with an anti puncture tape by Bell. I can't find any information about the product online, so I am sure it will not turn out well. The last time I performed this attempt I had a tire blowout in the middle of my commute home. The tape was loose inside the tire and caused the inner tube to build up pressure from the heat resulting in a pop. My current attempt is to place rubber cement inside the tire and then place the tape against it and hold it in place with another inner tube while it dries. I'll take the inner tube out tomorrow to inspect it's adhesive properties and if it is pretty attached I'll try it. The help I am asking for is if anyone knows a way to reinforce a tire through creative means that doesn't cause a flat through the modification. I would prefer not to damage the tire but will consider options. What types of glue would work well under the conditions of -01° to 62° C (30°F to 150° F) and speeds up to 68 kph (42 mph) This would be if the rubber cement doesn't hold out by tomorrow. What other methods can I use to enhance the tire to make it stronger? Soaking silk strips into glue then attaching them into the inside of the tire maybe? Other suggestions welcome. Lastly, What tires would work as an alternative? This solid tire did not work, it exploded after 4 days of use. I'm at the end of my rope here and would really love to sell this damn thing, but as it happens, no one as of yet wants to buy the thing, and I don't blame them. I'd imagine some of you creative people would have an idea that I could try and I am crazy enough to attempt it at this point. I appreciate any help anyone can provide. I'm open to all suggestions, even bad ones.
  12. How many people here I've actually worn tires bald on an euc? I'm just curious but guessing not many. On my ks16s I wore it bald enough to get a flat tonight. Luckily I have a replacement tire ready to go and my new tube should arrive tomorrow. Do to my riding style, I see many, many tire changes are in my future.
  13. Hello everyone. After doing a little more than 2500 km with my S2, it's time for me to change my tire. My tire became flat on the middle who totally changed the behavour of the wheel. I'm wondering if anyone put offroad tire like this one on his S2 or another type of uniwheel who was designed with road tire and changed for offroad and could give me a feedback. On a topic, i've readed someone saying it totally changed the behavour but in a terrible way ?. Anyone could confirm that ? And by the way if anyone know how to remove anti puncture bomb projection ? I have all over my rim ?. I didn't saw any solution except abrasive stuff like sandpaper Thanks :D
  14. Hi there, does anyone know on what’s the name of the tool that we use to access the tire on the KS 16s, I see that the valve is crooked or bent inward there...
  15. Yesterday I planned on goin on Nice long ride on the monster but right before I left I noticed the tire was flat, (thank god I have two other msupers) so I searched for the culprit but found nothing in the tire, so I decide to pump it up and i noticed that air was coming from the valve area, got some slime in there but it was still leaking, anyone experience this before? If you did how did you fix it?
  16. Sorry if this is answered elsewhere. I went to Walmart to buy that green slime but found 2 variants for tire and tube. Both looked same. Do inmotion V5F+ has tube at all? I can't scratch my head anymore!
  17. Hi, so I've got a flat in my tire and am looking to purchase a new inner tube or possibly a new tubeless tire for my Mten3. Anyone know where I can grab one? I'm really looking into grabbing a tubeless tire. I've also never changed my Mten3 tire but from some of the videos I've seen ,it doesn't look like a terribly difficult process. Thanks, Pavel
  18. Hello All, People usually ask me about how can i stand in balance while riding my euc. I have recently heard about spherical tires for cars. But this can be better for a euc bcs one can never lost his/her balance. Of course, for such a modification, EUCs have to upgrade their gyroscopic circuits. I just wanted to ask if this modification is simple or not? What do you think? Is this the future?
  19. EUCs with bigger wheel exists like 22" EUC while it does not increase stability in comparison with a 18" (am I correct?), but I think there is more need for EUCs with wider tires for better tire-road adherence and for higher torques. It increases safety because you can brake faster. It can give more acceleration without slipping and higher bending angles at startup. Last time I fell down at zero speed because I asked too much torque (bending too much) however I am only 65kg. At standstill I bowed too much forward, that I fell forward (with helmet). Since it is the most powerful EUC of the world, I had confidence on it but I had to limit my confidence. apparently 1kW nominal power and 3kW max. power (gotway msuper v2) is not enough sometimes, even for somebody of 65kg. Maybe no wider wheels are planned to produce for EUCs because of motor power limitations to 3kW max power. Is that the reason for motor power limitations? (on the other side, to be honest, riding at 30km/h on a steep hill of 30degrees, is in fact good enough as EUC power) Do somebody know if a EUC exists with a 18x4 tire? I have a 18x2.5 now. gotway msuper.
  20. So my mten3 inner tube got a puncture last week on the way into work. I was able to ride to work but it went completely flat by the afternoon (which is when I realized I got a flat). I filled the tube back up with a hand pump, god help me that took like 300 pumps to get it filled, I will get a foot pump next time. I could barely hear a very muffled hiss and it took over 30 minutes to deflate. This made me think that the hole was a pin price and not a gash. I tried to lever the mten3 tire off but broke 2 of the 3 plastic tire levers. I was hoping I could just do a rubber cement round patch, but the tire was not cooperating in this cold weather. I bit the bullet and bought 16oz of dirtbike innertube Slime. They were not kidding that it was a mess to use. I overshot the fill a bit and I think used 6/7oz instead of the recommended 4oz. It sealed the tube up immediately, no more hiss sound. I filled the tube back up to 45psi and it has been holding steady for 2 days. The Onewheel guys put slime into their tires from the factory and it's given that product a greater amount of tire reliability. The mten3 tire is ridiculously thin, I can't imagine how that innertube won't inevitably pop. Slime should help, or add an hard innertube protector against thorns, or convert to tubeless and use slime again. A small bottle of innertube slime (get the innertube one if you have an innertube, it is thinner and meant for a different pressure) is around $4 on Amazon, get one because you will need it eventually.
  21. Curious to see the favorite tire size preference for the favorite 16" EUC category....
  22. If you are having trouble threading the Ninebot One E+ extender stem to the inner tube's 'bent' stem valve then try this trick. Press the 'bent' inner tube stem valve down with a finger until it is in the same plane as the extender stem, thread the extender stem onto the inner tube stem and twist the extender stem tight on using a mm socket. These three pictures demonstrate my approach to threading the extender stem onto the Ninebot One E+ tube's stem valve. 1- stem extender valve not in the threading position 2- press the bent inner tube stem down with a finger (in plane, in line, almost flush with the metal hub) until it can thread onto the extender stem 3- Use an appropriate size mm hex socket to allow easier finger tightening of the extender stem onto the bent inner tube stem valve. In addition to a hand pump I carry a mm hex socket, the extender stem, an air pressure gauge, EUC battery charger and tire pressure gauge while riding to more distant destinations. I find the tire routinely deflates to about 40 psi overnight and I like to ride at 45-50 psi. It takes about 60 pumps from 40 psi using my hand pump to reach 50 psi. Slime markets an air pressure device which I also carry for longer rides.
  23. After 13000 km I had to change the tire on my ACM. I've put on a Schwalbe Mad Mike 16x2.125 and it is a totally different ride.
  24. Hi All, I'm a new rider to the Inmotion V8. It took several weeks to practice before I can actually go around the block. Anyways, now that I am actually riding beside the humming sound of the motor, I am hearing the tire scraping the cover as I ride. I'm riding with the cover on but did not felcro under the pedal. When I properly, felcro the cover under the pedals the scraping lessened. But I'm still getting some scraping of the tire and the cover. The scraping gets worse on paved road versus cement sidewalk. Is anyone else experiencing this? Any adjustment I can make? I've taken the nail clipper filer to try to file the cover down a bit but maybe not enough. Any help would be appreciated. Thank you.
