The MSX is a good wheel, either 84V or 100V. it depends if you are looking for range or performance... If range, it's the 84V, while for performance (speed) then it's the 100V. Mind you, the Nicola 100V has them both; range and performance. It might be worth it to wait; you'll have it for a long time, unless you are rich and can buy many...

In my experience, these outputs work in pairs (push/pull) If one fried (shorted) the other was affected as well and may fry soon after. So if you replace the one, also replace its complement. Also, it is possible that its driver(s) may have fried as well.

I disagree; I ride mine at 30 mph 90% of the time. This is only because at 31 mph it tilts back. So I teeter-totter on the beeps. At that speed, the wheel does not vibrate, nor does it wobble at all. It is absolutely straight, smooth, and stable. It only wobbles when hard braking at high speed; that's it. Also, even if the wheel would have a side shift of 1mm, the tire would reduce it by half. It would have to shift by at least 3 to 4 mm do be noticeable. I have measured mine, and it has just a little over 1mm side shift on the rim's edge. Even though your theory seems to give answer, why does mine not wobble at 30 mph, and only while braking hard? Lately, I'm trying to concentrate on putting equal pressure on both heals. This is kind of hard to achieve, because a few ounces more on one than the other will force the wheel to turn while braking. This is when your brain tries to equalize; but unsuccessfully. On a motorcycle, when the rake of the forks is too steep, the bike becomes more nimble, but prone to wobbling. This is why race bikes need steering dampeners. Is it a question of rider rake position? I never noticed this on my Ninebot One; it never went faster than 12 mph. Food for tought.

The KS 18XL also wobbles when braking hard. I've tried 35 psi down to 20 psi, not a bit of difference; the harder you brake, the more it wobbles. I guess you just got to get used to it. It might be simply that I put more pressure on one heel than the other without really knowing it; it's hard to tell.

I bought a brand new KS 18XL and cannot get to unlock because of the same problem. It requests permissions for: 1) to make and manage the phone calls on my device... 2) access photos, media, and files on my device... 3) to take pictures and record videos from my device... 4) record voices and audio through my device... If i deny any of these requests, it returns that it needs these permissions for the app to work normally; and gives only two choices: "cancel" which it freezes up, or "ok" which cycles the requests all over again. Why does kingsong need to invade all aspects of my device just to operate the wheel? Why can I not just unlock the wheel to use it? I bought a brick "0 miles". Boy am I pissed.

In the above reply, when I wrote "I" requested permission,... I forgot the "t" as in "IT" requested permission... which must have been confusing. Just to clarify.

In the same line of problems, I just bought a new KS 18XL and downloaded the android app from their website onto my tablet, and installed it. I enabled permission for location and storage. When I opened the app, I requested permission to: 1) allow Kingsong to make and manage phone calls on my device??? 2) access photos, media, and files on my device??? 3) take pictures and record videos from my device??? 4) record audio from my device??? If I do not allow these permissions, the app returns that it cannot open unless these permissions are granted. the only two choices it gives is cancel which it freezes there, or "ok" which cycles through these requests. I am not going to give Kingsong permission to invade my privacy to that extent just to ride their wheel. My wheel remains a beeping brick just the same. Kingsong app is downright frustrating to say the least. I which I never would have bought this wheel. I anyone has another way to unlock this wheel, I'm all ears.
