Tadas Posted September 5, 2019 Share Posted September 5, 2019 If you want to ride above 40 km/h, those tiltbacks will be really really annoying. And they start early, from 76 V idle. If you're happy staying below 30 km/h (=32 km/h wheel speed), then 16X is an amazing wheel! 2 Quote Link to comment Share on other sites More sharing options...
Chriull Posted September 5, 2019 Share Posted September 5, 2019 10 minutes ago, fryman said: Sure, if you ignore the tilt back or warning beeps. With the 16B it was "easily" possible to overlean before any tiltback started. Regarding beeps it depends at which speed they are set - if only at tiltback speed, no beeping will happen, too. Have no such overlean data for the KS16S or other wheels, it could be quite possible too. Just needs stronger acceleration and the overlean happens at higher speeds. Imho if one accelerates really hard in such ranges a tiltback won't help too much, anyhow as the overlean is just to come anyhow and not enough time left to react. 10 minutes ago, fryman said: My point is that the 16X should be safe with lower throttling and currently Kingsong is saying it is not. Somewhere here afair was reported that the KS16X can draw much more current as the KS18XL, so should also accelerate much better? As it seems this higher burden/acceleration possibilities are now countered with this new throttling? The only way to drive a wheel safely is to not accelerate to hard at higher speeds. 8 minutes ago, ir_fuel said: Yeah I don't really get what's going on either.

pico Posted September 5, 2019 Share Posted September 5, 2019 I read a lot of people comparing 18 inch wheels to 16 inch wheels. From an engineering point of view there is only so much ferromagnetic material you can pack on a 16inch wheel. In a brushless motor of a given size there is only so much power you can extract before saturating the core. (Even pushing efficiency to the max) For a given maximum allowable current at a given voltage (i.e. Watts) you have to compromise between torque(acceleration) and speed. I think the Kingsong fans have cornered the Kingsong engineers. (I must say, I saw this coming ) Been there... I remember saying, "The last 10% of performance gets you in 90% of the trouble" 1 Quote Link to comment Share on other sites More sharing options...

Mike Paolini Posted September 5, 2019 Share Posted September 5, 2019 23 hours ago, ir_fuel said: 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. @ir_fuel I'm not sure yours is the total picture - because the the same sampling rate is applied consistently (1Hz which is sample per second). Moving into more detail though, since GPS is providing 1 location point every second, we can measure total distance traveled in that 1 second (and here I'm assuming no wobble or bounce issues). And that allows for us to compute the time it took, in fractions of a second, to cover the distance (e.g. Assuming I've done my math correctly, @ 20kph over a period of 1.6 seconds a distance of 8.89 meters would be traveled and over 2 seconds it would be 11.11 meters). So given GPS point T1 minus point T0 it is reasonable to compute when we reached 20khp in tenth of a second accuracy. Which brings me to my next point, GPS isn't the only way to do it. Going a different path leveraging the accelerometers - which on the iPhone at least sample at 50Hz - a sample ever 0.02 seconds. And naturally two methods could be combined as well. So while it may not reach the level of precision in sampling you' prefer for the GPS method alone, it does not invalidate it, it simply requires more math to figure to walk backwards from the total distance traveled to compute what the time in seconds would have been at a target speed of 20khp. And even if the programer was lazy, it would still provides an indication of what a higher sampling rate would point to - both wheels are reaching similar speeds at similar intervals. Lastly, for what it is worth, people have tested these apps against the measurements on quarter mile tracks with pretty good results. 3 Quote Link to comment Share on other sites More sharing options...

Popular Post Mike Paolini Posted September 5, 2019 Popular Post Share Posted September 5, 2019 (edited) I honestly do not know what all the whining is about for 1.06. The KS16x is fun wheel and it delivers. And maybe its just me, but I'm okay with safety limitations to keep me upright, skin on my bones, and all my teeth configured as they currently are. We as a riding community should be DEMANDING safety first and foremost. Performance comes after safety - because if it is the other way around, eventually these will be outlawed everywhere. Also I'm not really sure that a *version 1.0* of a *brand new engine* and *new control system* (and the new software also going with it), running a 16x3" tire, really belongs at speeds greater than 25 mph in the first place - at 40% or 100% of battery. If you need those kinds of speeds, maybe think 18" or 22" 100v (not 16" 84v). As it is, I can feel myself become airborne in the 20's and I'm heavier rider (also riding at 35-37 PSI). That fat tire *does* transmit more road noise to the rider (which I assume is why a lot of you are running it below manufacture recommended PSI levels), and this combines with the higher peddles, which while wonderful off road and at lower speeds for turns, result in a higher center of gravity and less stability (e.g. infamous hard acc and breaking side-to-side-wobbles - though tire may has have input into this). Nothing comes for free, there is always a trade off. So my 2 cents, King Song keep doing what you are doing. If you can zero in on the numbers to give us a bit more, great, if not, that is cool also. Because the KS16x is great wheel, and I dig it as is. (But I do wish you'd fix the BlueTooth .25 second lost playback and release the iOS app that shows the correct power levels).

There does exist another 16" EUC that barely breaks a sweat cruising 35+ mph, lets you do 30+ mph at 25% battery with plenty of buffer, has a cushy stock tire, and feels rock steady at speed compared to the squirrely 18XL. If this other wheel did not exist, we would be obliviously happy with the 16X as it is. 7 Quote Link to comment Share on other sites More sharing options...
Popular Post Flying W Posted September 5, 2019 Popular Post Share Posted September 5, 2019 If this throttling worked like @Micheal Shen said, no aggressive acceleration between 40kph and 50kph will still let you get to 50kph, then this may be fine but it seems like that is not true and the wheel limits you no matter how you accelerate. It's a shame.....everything else about this wheel sounds amazing but I will hold off on buying one until this is resolved. The while point of a larger battery is to have fun longer but this isnt jumping from an 800wh class wheel to 1600, more like 800 to 1200wh ish performance wise with a huge "limp home mode". Anyone who is a 250lb rider already knows they need to be more careful. I'm in the 190s when geared up and I dont accelerate like some of the lighter riders I see on YouTube because I know I'm heavier. I'm sure kingsong can have a heavier rider do some testing. They fixed it on the XL but look at how many bought the MSX instead durring the backlash. And that wheel wasnt advertised at 25% and changed after the fact. Now that the new limit is not mentioned in the change logs for the update there will be people who dont frequent these forums updating and wondering why their wheel is throttling so early as well. For @stephen to be stuck at 20mph after only 20 miles is totally ridiculous, I can do that on an 800wh wheel. Fixing this sooner rather than later will save a lot of sales. If a fix cannot be done due to safety concerns then I think kingsong should tell us exactly why. It takes more torque to turn an 18in wheel like the XL and we already know a 16in xan do this (Nicola, Tesla). 7 Quote Link to comment Share on other sites More sharing options...

If I knew they would have implemented this throttling, I would have gone for a different wheel. I bought this wheel with they idea when i'm riding 40kph, I still have enough reserve without hitting warnings/tiltback all the time like a had with my 16b. I still think it's weird why all of the sudden they added throttling at 74v, either they know something or something went wrong in their calculations.

I suppose if the 16X existed in a vacuum (no other competitors, including the 18XL) and we were in 2016, yeah, the 16X would be fantastic. So you're on a 40-mile ride and after ~20-miles you're limited to the low-20's??? Given all the other wheels out there (including other KingSong models), this 1.06 behavior is lame and worthy of labeling the 16X as a Intermediate Wheel.

You do know that both KingSong and Gotway speeds are usually about ~10% off, right? I haven't tested the 16X, but most other wheels are incorrect. So 25-mph is actually closer to ~22-mph.

stephen Posted September 5, 2019 Share Posted September 5, 2019 (edited) Here's my 2 screens of speed you can clearly see after my days ride where it started throttling .. Plus you can clearly see i wasn't doing top speeds even when i had the voltage if i did my battery would of gone down quicker, and if i had I'd even have less fun of a day out Look at the speed it was only a leisurely range test too 1st screen is the return home and 2nd screen is the beginning If i was on a clear stretch the please decelerate and tiltback would of been constant but that why i bought the 16x because i don't have clear stretches but when it is clear i want to do at least 25mph , i didn't exactly floor it did i Edited September 5, 2019 by stephen 1 Quote Link to comment Share on other sites More sharing options...
