No one in the world has succeeded to “ride out” a cut off wheel so far. So, either you’re a Guinness book person, or there is much more to the story. Can you please give all the details.

Yes. This should eliminate the wobbling tendency. Look here, from 3:01: You can even see some wobbling there. And you can also see that he rides NOT EVEN TOUCHING the sides of the wheel. This is the recipe for wobbling. This wheel DESPERATELY needs bigger pads.

IMHO the reason for the wobbling “issue” is the combination of high pedals and little support in the upper area, which allows tilting the wheel between the legs. Thicker pads should solve this, actually I expected KIngSong to make this change.

I have one of the first preorders and will be happy with ether shock, AS LONG AS THERE IS NO CLEARANCE ISSUE WITH THE 36. If there is an issue, then I consider it just unfair to ship me a wheel with a known issue just to save the cost (and make me buy a different shock).

I'm quite sure you don't want a couple more of these, do you? It's obvious from your posts that you want speed but don't understand the difference between an EUC and an electric skateboard. This is a very dangerous combination. What would happen if your skateboard reaches its maximum engine or battery power, for a fraction of a second? - Your skateboard would just stop accelerating, you wouldn't even notice it. What would happen if your EUC reaches its maximum engine or battery power, for a fraction of a second? - YOU'D GET SCATTERED ON THE TARMAC. You wouldn't even have time to understand what's happened to you. This is the main and paramount difference. That's why any self-balancing device must have a hefty reserve of the power and speed at all times, and a "speed unlock" is a thing which should be done with the GREATEST caution, or better never done at all. Even the limitations set by the manufacturer are mostly a wild guess, they cannot consider all the conditions (wind, slope, bumps, sand, temperature, rider weight, battery age, etc., etc.). But this is your health. IT JUST HAS TO HAPPEN ONCE. And it can happen even without warning. The "high speed firmware" is made for people with great experience ON EUCs, not on skateboards, Formula 1 or whatever, who perfectly understand how SELF-BALANCING devices work and can count on all the conditions choosing the current speed. And they, beleive me, will very rarely use the maximum speed allowed by this firmware.

Actually by the way things are going, it looks more like Inmotion has rushed their presentation to match Kingsong. (Changing the V11 pedal height is certainly no small change!) Inmotion has better "polish" but more history of major issues, which they are much more slow and reluctant to fix. I'd rather get panels falling off a sturdy and reliable wheel than a polished piece of s..t that'd kill me without warning.

I honestly don't understand all the scepticism. We all know that KingSong is no Mercedes Benz and they don't have the attention to details as of Maybach premium models. I expected such MINOR issues like pads falling off and the tire rubbing. (By the way, 18" Stridas rub their forward tires on some screw and are still very popular anyways). I can bet issues like that will be still present in early production wheels. But we also know that Kingsong also avoided MAJOR (that is rendering the wheel unusable and/or dangerous for riders) issues in their new wheels so far. This is the most important thing. If, for example, we saw a high speed cut off, a broken suspension or the shock shot into the riders' anus - that've been a completely different story. I hope (and am rather sure) Kingsong is focusing on THAT. And these small issues will be eventually sorted out via the warranty and recalls. So, nothing awful so far.

Hello! I’m considering preordering the S18. But there’s one consideration which really scares me. Since the whole wheel except the motor is suspended, the wires going into the motor will be constantly moving and bending. Unless this place is perfectly designed, there is a great risk of damaging or fatiguing these wires, which will lead to an in-motion cut off and injuring the rider. Can you please explain what measures are taken in the design to prevent this, or, better, provide a photo? KingSong has always had a reputation that whatever glitches a wheel has, it never “kills” the rider. This is what I love KS for. I really hope it stays like this.

Yes, that's clear. But if we just assume the sensor might be the culprit, it'd be great to know if it's enough to shut off it in the app. Let's say it another way: that's a question of a "clean experiment". If someone has the issue when the sensor is turned off in the app - can we confidently say "No, the sensor is not the culprit, forget it"? Or do we still have a chance that the sensor _is_ the culprit but should have been disconnected physically?

Can you please make sure with Kingsong: is it enough to turn it off in the app? Can it happen so that the controller still receives the signals from the sensor and process them even in the "off" state, disabling just the motor deactivation? In this case a physical disconnect of the sensor might be required to prudently avoid the issue. The engineers who designed the algorythm should know that.

Actually that's a good question. Just FYI: If water gets to battery cells somehow, the wheel is VERY likely to catch fire, not immediately, but with 12+ hours delay. There was a case in Russia where a guy sunk his KS14s 840 in a pond. He then disassembled it and removed the water (he thought so), but the wheel still caught fire at night, thankfully no deaths, but his apartment was heavily damaged. And 18L has a design feature that can be dangerous in some curcumstances: its battery boxes are flat and long, and the lowest cells hang very low, just above the pedals. Just yesterday a guy from Belarus accidentally got on an 18L into a puddle which reached the tops of his shoes. He was advised to disassemble and check his wheel immediatlely, the outcome is still unknown. Even without ponds and knee deep puddles, I've seen dust in an opened 18L at the level higher than the lowest battery cells. That raises the question: can the wetness reach the batteries from the bottom even when just riding on shallow puddles? I'm not sure the battery boxes are waterproof except just the closed plastic box. Besides that, I guess the only other question is isolation of the wheel compartment. Is it waterproof enough from the factory? All the rest is protected by a plastic bag or a waterproof backpack cover put on the wheel's top, which is always a good idea in a considerable rain.
