I would not trust any EUC at max speed when going below 30%.... easy for me to say though as I have my S18 set to max-beeps at 35 kph. When I drop below 30% I do not exceed 25 kph.

There are several charts floating around, the "official KS" chart being one of them. As stated, the chart is flawed, not to mentioned the method they use with the block between the pipes when inflating and putting in the pressure. For me it was a trial and error procedure. All the early trials were useless as the suspension was seriously binding. Once I had that issue resolved with the suspension overhaul, I started tinkering and found settings that are right for my wheel. Thats the other parameter that needs to be taken into account, all these wheels seem to be "individual" and no two are alike... so the pressure I use may not work on your wheel even if we would have the same weight. My recommendation would be to just trial and error it to find the pressures that feel right to you. Just for information, I have ended up at 200 / 80 (I do not use the block) as my go to setting. I check it every few months and I see only a slight drop in negative pressure from time to time, which most likely is attributed to the escape of pressure when you detach the pump hose.

Any update on this? I am on 2.06 still and I have always had this "issue". There is a simple fix though as earlier mentioned, power cycle the wheel as soon as it has charged full --> I am afraid that balancing never happens on the S-18 though as charging is cut and you still have the 0.3A draw from the motherboard (with bluetooth) being kept alive.

I can second this statement. I am running the H666 (Love it!), but when we were looking for a replacement to the original tire (Only good for pavement riding, horrible on single tracks) the H666 was not available so we went with the Heidenau K66 80-90-14. For the S18, this is a tad bit to wide/tall. It will rub. It was annoying for the 1st 200 km, then the tire would "settle in", in other words, it shaved off enough on its own and has since performed great. Quick tip is to slightly over inflate it, ride it until it shaves off the excess and then deflate it to your normal riding pressure.

Yeah. I do the same. I believe I am on 2.06 on mine... and no need to update. The only "issue" I have is that the BT module appears to stay on after charging the wheel. Power cycling the wheel after full charge stops this phantom drain.... something I am used to by now and never forget and in all honesty is only a really small nuisance.

This is not uncommon practice. I work in the medical imaging field and even though we have very rigorous testing procedures some "bugs" are always reported by our users after new firmware releases. The most challenging issue to handle is the difference in hardware generations. Sometimes it is impossible to test, which is why the proper way of releases is to lock it to certain HW revisions, which would make a lot of older customers dissatisfied as they do not get the new features associated with the new firmware. In this intance I believe KS did a knee-jerk reaction and deleted the firmware, re-tested it to the best of their abilities and re-issued the release. They should have re-issued it as a 2.13 though... The biggest challenge for these chinese manufacturers seem to be clear communications. Proper release notes etc. Heck, we all know that there will be known issues, but for transparency just list them, then the consumer will be more tolerant and accept the deficiency knowing that it is a known issue that (hopefully) someone is looking into.

Nice info in this thread! I just wanted to share a quick comment that these battery related "issues" are not unique to EUC's. I have a plugin outlander PHEV, which has a rated battery capacity of 12 kWh. I recently upgraded my home charger with one that actually measures and when the car has a depleted battery (0 km range) and I charge it to full, then I have charged a total of 7-8 kWh. In other words, the "rated" capacity may be 12 kWh but the usable capacity is only max 8 kWh. The same goes with EUC's, which is why it is so hard to compare a KS wheel to an inmition or a Gotway. They can all be depleted to different levels and use different pack configurations. Best is to compare model to model to understand if your wheel is underperforming. I love my S-18, but I think we can all agree that the battery is too small. I wish KS would listen and make a S-18L or XL version. From the DIY projects that some have been doing we all know it is doable and that the frame can fit larger packs.

My buddy is running the K66 on his S18. It is a TIGHT fit! But super happy!

Mulle meni myös viikkoja ennen kuin pääsin liikkeelle ilman tukea. Sit kaverini haluisi oppia ja hänen kanssa tehtiin niin että hän piti minua olkapäästä kiinni ja kävelin vieressä tukena. Ei mennyt kun 20 minuuttia ennen kuin hän ajoi ilman tukea.

I 3D printed a couple of covers for the top sliders. Works like a charm!

This is a sad fact. I have a 1st batch (pre-order) S18 and I expected this from my wheel. Suspension was basically non-functioning. I had to completely dis-assemble the wheel to "free up" the movement. Replaced probably 30-40 screws, added nylon sliding washers, removed locking washers etc. After the overhaul it works great though! KS has apparently not been following this board a whole lot as there is a mammoth-thread regarding how to overhault the suspension. All new wheels still have the same issue to various degrees. This is also a fact. Battery definitely could be larger, especially if you are a heavier rider. I am only 80kg geared up, so for me the range is acceptable at about 60-65km per charge. This is a matter of taste. I am bow-legged, so I actually added another 1 cm piece of foam to the outside of the integrated pads to make it fit my riding style. to each their own. See point one in my reply regarding the suspension. Other issues are a slightly misaligned fender that rubs a bit. I run a H-666 tire without issue and my buddy has a Heidenau K-66. It had a slight rubbing that disappeared after about 250km of riding. tight fit, but it is managable. And like @mrelwood stated, custom parts are almost required to keep the EUC in good working order. I have 3D printed motor cover and sliding bar seal protections. Easy to make if you have access to a 3D printer, but a hassle. Should not be a deterrent in my opinion. If you ask or get a response from a V11 owner, then they will rave about it. If you ask and get a response from an S18 owner who has overhauled the suspension, then they will rave about it. We are all fanboys and want to justify our expensive purchase. I do disagree with @mrelwood on this statement though that you can not compare the wheels. We all have different criteria for what we want out of a wheel and I can honestly say that I would be equally happy with a V11 or S18. I am a casual rider though, only racking up about 1500 km or so each season. The S18 should have a buyer-beware sticker added to it. In order to make it functional you will have to do some TLC to it. But once that is complete it is a joy to ride.

Tämä laillisuuskes kuskustelu on vaikea. Fakta on kuitenkin että me EUC kuskit ovat ainut jotka edes kiinnostaa käydä tämä keskustelu. lakisäätäjät eivät ymmärrä eivätkä haluaa ymmärtää esim että suurempi teho = suurempi jarruvoima. Tämä on myös erittäin vaarallinen argumentti, koska heidän mielestä pitäisi kai kieltää laitteet missä ei ole "kunnon" jarru... itse tyydyn siihen että ajaan maalaisjärjellä ja jos joku konstaapeli sitten haluaa sakottaa niin otan sen kiltisti vastaan ja maksan sen samantien.... koska tiedän ettei laite ole laillinen ja en näe mahdollisuutta miten sitä saisi lailliseksi (ja V5Fllä en meinaa alkaa ajaa )

Has anyone found any release notes on the 2.07 firmware? I am curious to a) what it includes and b) why is it not available through EUC World @Seba?

Forgot to add for anyone that is interested in doing this mod, search aliexpress for "pedal studs" and you can find several hits for a kit of 50 pcs for 3-4 bucks + shipping. I believe I paid total €6 for mine delivered. Just order it and use the cold, dark winter nights to baby your wheel!

Thanks for sharing this! I have downloaded the files from thingverse and will be printing it later this week.
