  1. 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.
  2. Good day all, I am selling my 2018 KS-14S 840Wh/800W black wheel. My story follows... In 2018 I moved to Charleston, SC, and as a hair-brained idea to beat traffic here in the city, I purchased a King Song 14S to ride to work from EWheels, along with a fast charger. Good thing too, as the stock chargers for King Song wheels tend to get hotter than you might expect. I have also done some recreational riding in my off time and have enjoyed this wheel as an intriguing, head-turning way to get around. However, recently, I rode to work, and took a low-speed tumble as I caught one of the pedals on a curb while transitioning across a parking garage drive, thus throwing me off the wheel. I had my hands out to catch myself, and wrist pads, elbow pads, knee pads, and helmet, and still managed to break my arm. All of this at less than 5mph. While I realize there are some older riders in the group, I am coming to grips that even though I'm not 40 yet, I am getting fragile as I age, and i need to be making better decisions as to the things I attempt to do and the consequences it may entail. And although I have enjoyed this wheel, and want to continue riding it, the sad truth is that there just isn't good infrastructure anywhere in this area to do so to commute, and it is largely unsafe. This is a town I'm nervous to DRIVE in, much less ride on an EUC. So, I've decided to put my wheel up for sale. Despite it being a learner wheel, it is in good operational condition, but with some cosmetic storytelling to go along with it, primarily the foot pedals, and some minor body scuffs. There is no broken plastic, and the only thing electronic that's questionable is one LED on one side that is missing some green output. I started to learn to ride in the grass where any falls I would suffer would be softened by the dirt underneath, and would save harm to myself and the wheel. I went into this ordeal knowing it was going to get scuffed up because I've never ridden one of these before. This wheel is black, and I have applied some of the piping that comes in the box to its casing to save some scuffs if I can. The foot pegs, as I mentioned, are scarred up a moderate amount from my learning experiences, but are in good repair otherwise. It has 563.5KIm on the clock, so fairly low mileage, and it will charge completely. My research on battery care indicates that it is best to keep the battery between 30-80% most of the time, with the occasional charge to 100% when you know you are going to ride it soon thereafter. The quick charger will be included and has the capacity to select 3, 4, or 5A charging, and to cut it off at 80, 90, or 100% charge It also has a fan in it, and a voltage readout, and is built with heavier gauge wires than the stock charger. I will include both, and the original box, which is a double-box. All safety functions work correctly including tilt-back, speakers, voice warnings and lights, and this wheel is bi-directional. It has a headlight and tail/brake light on both sides. It's on the original tire, which still has a good tread on it, and the wheel has been stored with roughly 45% charge on it. It's never a good idea to store it with a full charge. I have not had to open this wheel for any reason. It has never cut out on me, and despite cutting it close on available range, has never left me stranded. I wish I could advertise a pristine wheel, but that's not the case. Anyone who takes up EUC riding has to learn somewhere, and this one was mine. I've gotten back up and back "in the saddle" more than my fair share of times, but a broken arm is going to have to be a stopping point for me. I can only take so much abuse before I draw the line, and say, "yeah, this was kind of a crazy idea to begin with," but what a ride! I really enjoyed my time. I just wish my local infrastructure was better, and the same for my personal biological infrastructure. Thanks for reading, and I will update and lock appropriately when this wheel moves. Pictures will be provided upon request. Feel free to ask me anything you like about this, and I will do my best to answer your questions. Asking $750 shipped, MSRP on EWheels is $1,175+tax.
  3. Hi everyone, Been looking at my first EUC for sometime and must say im so lucky to be part of this community. I have been looking at different specs, pricepoints, brand reputation etc. Looking for an EUC that will help with my almost 3 mile commute in the mornings to my Bus Stop and return at the end of my work day. I must say I will probably not ride any EUC for sometime that I can safely jump off of at any speed (dont know what that max is yet!). Some requirements would be a good battery, strong motor and easy to transport/carry. I am more and more drawn to (2) options the Kingsong 14d or the Gotway Mten3...for some reason I keep getting pulled back to the Gotway..although it doesnt have a light (for night riding) im sure thats a simple fix, bigger debate is that they are almost at the same pricepoint! sooooooo with that said one or the other? and why are you convinced?
  4. Looks like the MCM5 has landed in Paris / Gyroroue shop:
  5. had a freaky flip over yesterday. Just walked it off, no biggie, but when I picked up Lassie (my wheel), the tire was flat. Inspection revealed the (bent) valve stem was rotated 180 Deg. And had ripped out of the tube. I know what happened, but it's not the subject of this post. Why is it so freaking hard to find a 14" inner tube in Europe. Jason's got one in the US, but my cost delivered is $55. Keep looking. if you don't know, EUC s need a special bent valve stem parallel to the tube not at 90deg or straight, So local bike shop or FleaBay is not an option
  6. Eventhough I got this wheel just about three months ago, I'm already looking to upgrade. Why? I feel the need for more range. This wheel can do 12-14km, but I simply want to go on for longer and not have to carry an extra battery around. Other than the range, I have no remarks about the wheel. Its fast ( I've reached 26km/h ), the automatic lights work great, and the bluetooth speaker sound pretty good too. 174wh swappable battery 25km/h top speed ( cruising speed ~22km/h) Automatic lights ( works great from my experience) + brake light Integrated bluetooth speaker Build quality seems really solid. I haven't really dropped it yet, so no mayor scratches. Milage is about 200km I'd say( The total mileage has reset itself a few times for some reason, I think its something with the app) As I said, I got it less than two months ago, so It's as good as new. Feel free to make an offer if you're interested. - Shipping to EU is possible ( but expensive; starts at €34) - Shipping to NL €13,25 -Pickup in Arnhem,GL is also possible IMO this is a great first wheel, cheap but good qualitiy/speed/features. Also good for someone looking for a cheap short range commuter. Feel free to contact me for more information.
