Yes that question is stupid, I agree with you. When I go to the dealership I will not asked which one is the least safe or which one is the slowest or which one is the ugliest. If I want to buy a track car I will ask which one can I turn traction control off. Is like an Aventador but with traction control, lane keep assist, lane departure warning, lane change warning and auto start stop ALWAYS ON all the time.

With that said, if you want high safety margin why not asked Kingsong to throttle from 85% besting Inmotion? Higher safety margin is better right? Don't forget there's also a drawback with tilt back like it could make you lose balance when hitting a bump below 50% battery or will not allow you to accelerate fast enough to avoid hazard. Both are dangerous. The earlier the throttling the more often it can happen and can cause accidents.

I know I can always choose other wheel. I'm just mad the one that I want is nerfed so bad and only Kingsong can do something about it. It's like Kingsong just made a mona lisa but just decided to put googely eyes on it.. Or this:

Yes Kingsong, I'm still mad. At least give us choice to lower it.

I’m still holding on to V1.05 on my KS16X. 

 

Could someone answer definitely once and for all what happens when a V1.06 KS16X reaches that magical 76V?

 

 

 

 

Depending on load it starts to throttling and resist if it gets too much. I will be updating mine today. But as I wrote earlier it is like not to effect me that much as I am anything but aggressive when riding, nor do I ride at wheel top speed/performance either.

So I actually view this as a help for me to not push the wheel so far I get in trouble, despite I am unlikely to do that ever. I do like the safety view KS is trying to make here. You can ride fast but you can't be too demanding when doing that. or you can ride aggressive but just not do it at the top part of the speed curve of the wheel.

The speed throttling is implemented STARTING on 50%(74Volt) and then going down to 61Volt(0%) ...reaching 25kmh on 0%.

this means in theorie that 45kmh are reached at about 70-72Volt, 40kmh at 66-68, 35kmh at about 68-66Volt, 30kmh at 64-62Volt!

while i have to say anything under 66 is allready VERY empty and due to voltage drop no fun to drive!

Please Dont nail my on totally exakt numbers, as these are numbers under load....

A try of a graphical representation:

But the hole Idea is it is not linear and it depends on the conditions. So the curves you have will be adapted by rider weight, road decline/incline. and so on....it is much more complex than the simple graphs.

From what is written here (btw - thanks for the collection of @Micheal Shen's and @US69's relevants posts here!) it is in my opinion not clear how it is to be understood.

If either:

- the tiltback speed reduction is linear to battery voltage, but as different burden situations (riders weight, inclines, acceleration, etc) by the voltage sag change the battery voltage this makes this whole behaviour non-linear.

- they made the speed reduction over battery voltage in some way non-linear.

Did not get a real hint to believe that the second possibility was implemented, but also no confirmation that they "stayed" with possibility one.

I just tend to stay with possibility one - that was how it was imlplemented till now with most (?all?) wheels and if KS would have "invented" something great and new they'd put this in the advertising machinery?!

But yes - it's guessing, and by scanning the last pages i've seen that i missed the announcement of a new firmware in the pipeline? ... so everthing is very likely to change again...

It's not a fair comparison. We're riding on one wheel. The wheel always needs a reserve of power to maintain balance.

If I hit a pothole at high speed and fall forwards, the wheel needs huge power to catch up. Voltage drop is a real thing with the batteries.

 It’s an excellent example. I’m talking about changing what you advertised.   We have potholes everywhere here in Florida. Fortunately you can see them.

Wonder if the new 2200W motor would require a 100V system to get the throttling lower or hopefully just a FW fix?

This is new territory for KingSong and they hurriedly released a wheel to not get slaughtered by the Nikola.

Oh they're so far behind the Nikola's performance, I don't think they're even aiming to match the Nikola's specs. 

I think it was more of not missing out on summer, aka peak sell time.

 Before the latest firmware update I had grinding at ultra low speed’s going back-and-forth. I thought I posted the video here.  I’ll post it here. After the firmware update it doesn’t do it anymore. 

Holy crap, that sounds like a pet pig or a branch that's caught up inside your wheel! I've never heard that sound while trollying or at low speeds and I'm still on 1.05.

Lol Trying to start a fire?  Besides I own both and disagree with you vehemently. 

Do you have the 100V Plus?

Yup. And the 16X with CX tire

Lol I know right. Fortunately 1.06 got rid of that noise.

Hi guys,

@chrisjunlee
I've tested a friends Nikola plus to compare with KS16X (fw1.06), I used "dragracer" app to see how fast both EUCs reaches different set speeds, here are my personal results :

Nikola Plus :

20kph = 1.9s / 30kph = 2.8s / 40 kph = 4.2s / 50 kph = 5.7s

KS16X :

20kph = 1.7s / 30kph = 2.5s / 40 kph = 4.1s / 50 kph = 6.1s

My feeling on both EUC's is that KS accelerates faster, but I am having more trouble reaching top speed on the KS16X because of tilt back, I don't feel as comfortable around 50kph with the KS while the Nikola can pass it with ease ! Actually I've put more miles on the Nikola, I am a little less used to the 16X. I accelerated on flat surface with 90-100% battery as fast as I could.
Both are very powerful EUCs and I think they are both excellent, Nikola has a more "smooth" initial feeling like riding on a magic carpet, the Kingsong is a little more "rough" but still very smooth.
I feel that at low and medium speeds (from 0 to 30kph) 16X is more nimble, at higher speeds it's very similar. Of course Nikola has a much higher top speed.
Regarding the 1.06 firmware of the KS16X, I changed my mind on it, it's awful because I only get about 40kph at 74V now. I hope they will fix it in 1.07 firmware.

Sorry, but measuring sub 2-seconds accelerations with a phone app?

That's never going to be accurate. Your phone does GPS sampling at 1Hz. That's 1 sample per second, including the lack of GPS accuracy. How will this ever give a meaningful result where you can compare 1.9s vs 1.7s. or 5.7 vs 6.1.

If you don't have at least 10Hz sampling with a high precision active GPS antenna, the results are worthless.

After 8km I hit tiltback: max speed 44km/h, road was flat and in good condition and tailwind

Why is it tilting you back at 44kmh it should be 50kmh at the battery level

I am struggling to find any benefit to 18XL... 18XL probably has better range, but with the huge battery packs, I don't care about range.

Have you not been paying attention? Not only does the 18XL have better range, but it stays at max speed for a much larger portion of that range (down to 25% battery) compared to the latest firmware on the 16X which is now throttling super-early (as early as 50% battery or some claiming as early as 60%). Also the 18XL's thinner tire and larger diameter should theoretically be more stable/smoother at higher speeds on good road surfaces and might have less gyro effect when turning.

  • 16X -- better acceleration, slightly less stable at high speeds and top speed quickly drops with battery
  • 18XL -- better for cruising longer distances at high speeds all the way down to 25% battery

The best wheel for you is always the one that suits your needs the most.
