That also Shows that when a on a running belt with a 66/78kg Person(no matter) and the wheel shuts down at 35kmh something is wrong! Very wrong! 42 Lift Speed cut out also is way to low! Like i said....even the KS16 with 800W can go to 48kmh on this test and is advertised 30kmh......So i would exspect the KS18 1200W at least to be near at 48kmh also!!! Mainboard or Batterie defect, whatever...Somethings defect or wrong!!! In this Video the KS18 1200Watt with only 680wh goes easy to 38kmh!: Quote Link to comment Share on other sites More sharing options...
HEC Posted July 4, 2016 Share Posted July 4, 2016 @KingSong69 Yeah - it looks like half of the battery packs might have lost connection or blown fuses .. 1 Quote Link to comment Share on other sites More sharing options...

Yip....Could be nearly everything...also perhaps something sits between wheel and pedal...or bolts from wheel are to "heavy closed".....so the wheel Needs to much energy for rotating...sorry my explaining is not the best in english :-) Seams like he could "readjust" or "retest" the Scenario.....so fault is still there....not a "one timer" Quote Link to comment Share on other sites More sharing options...

Cloud Posted July 4, 2016 Share Posted July 4, 2016 Is it possible that they put in the controller from the 800w version by mistake? maybe you can take pictures of the controller and post it so we can see Quote Link to comment Share on other sites More sharing options...

That also Shows that when a on a running belt with a 66/78kg Person(no matter) and the wheel shuts down at 35kmh something is wrong! Very wrong! The more load is on the wheel, the earlier it stops. So the more load (driver weight) is put on it the lower the max speed is. Especially inclines - even very small (almost not seeable) ones can make quite some difference. Also headwind has a big influence. You for sure already noticed this riding a bike - you feel every little incline as quite some extra burden (and your max speed reduces) the running belt also induces some extra burden and reduces the max speed. The max cutoff speed is no fixed value! 2 hours ago, KingSong69 said: 42 Lift Speed cut out also is way to low! Than you either have some mechanical problem (i.e. a bad bearing) which leads to a higher than normal motor burden or some "electrical problems" (?bad shunt for current measuring, out of spec mosfets,...?) or "bad windings/magnets" in the motor - something gives an extra burden to the system (or reduces max power of the system) and reduces your max lift cut off speed. but again - never believe, that you can ride a wheel up to the lift cut off speed - thats maybe works going down or with tailwind, but just a little extra burden (headwind, incline) and your cut off speed will be much lower. also setting the tilt-back near the "max speed" is very dangerous - the tilt back is "an extra burden" and the wheel has to accelerate and so maybe overshoots the max speed leading to a cutoff! 2 hours ago, KingSong69 said: Like i said....even the KS16 with 800W can go to 48kmh on this test and is advertised 30kmh......So i would exspect the KS18 1200W at least to be near at 48kmh also!!! Wheels with a bigger diameter have less torque and need more motor power for the same performance. Bit this should be linear? and 16 to 18 is a lower factor than 800 to 1200. but still the wheel diameter and the motor power have no direct influence on the max speed. The only give the possibility - the max lift cut of speed is determined by the motor coil windings. ...or maybe this is just the tolerance of the series production and you got a wheel from a charge of the lowest end? 2 hours ago, KingSong69 said: Mainboard or Batterie defect, whatever...Somethings defect or wrong!!! Could be. But please don't compare the ks16 with the ks18 - they have different motors and could so have totally different speed characteristics. ps.: hope you get well and overcome this nasty accident! 4 Quote Link to comment Share on other sites More sharing options...
US69 Posted July 4, 2016 Share Posted July 4, 2016 @Chriull with my post i only want to say that something is very wrong... was no comparison between ks16 and 18.. but normally KS is known to reach the advertised speed....40 with this Ks18 version....so the lift of max speed has at least to be a bit higher than 42.... and this 30-35 shut down behaviour seams ro be reproducable...something very odd with this wheel is wrong...my opinion...thats all and: i am not the "faceplanter" in this case.....just tried to help for searching the fault.... so....thanks for the wishes to get well... 1 Quote Link to comment Share on other sites More sharing options...

So what you saying is that if two people one 65 Kg and one 105 Kg will ride the same wheel at the same speed under the same conditions and start breaking at the same spot / time with the same "effort" that the heavy one will stop sooner / at shorter distance? Based purely on kinetic energy of both riders I'd expect exactly opposite results ... Quote Link to comment Share on other sites More sharing options...

With "stops earlier" i meant the cutoff happens at a lower speed - did not mean to relate this anyhow to breaking.

Have you considered the possibility, that maybe you bought a counterfeit unicycle? They are common in China. Of course, their performance is below the original ones. Your King Song's performance is well below what everybody else's KS is, which points towards the theory that you possibly purchased a counterfeit machine, unknowingly. Meaning, the seller being a crook. Open it up and post some pics so it can be dissected by the forum.

Using the control board from the 800w unit would explain what happened. Or perhaps the entire unit is 800w instead if 1200w? I guess it couldnt be be ause you were able to set the speed to 40? What does the motor say? Does it say the wattage? Edited July 4, 2016 by Cloud Quote Link to comment Share on other sites More sharing options...

For example my wheel is 14" ks 800w that is not supposed to go over 30 kph, but by mistake kingsong forgot to limit my speed, and i am able to set it to any speed i want currently set to 30 for the beeps and 32 for tiltback. anything coukd have happened, i would check both the control board and the motor. When your friend comes over show us the pics. In the meantime get well soon. Thanks Quote Link to comment Share on other sites More sharing options...

That with "this -special- pictures" is just since two or three weeks....before he only had the original SidePanel's photos and wheels!....i watch this seller a Little longer...... In his bad english he tried to explain on some KS Sell-WebSide's that KingSong since middle 2016 has changed for China/Asia his sidepanels Name to "KSwheels"..... As i know that KingSong's Name, Reputation and Sellings in China is until now not the best (because to expensive) and they mostly sell to europe.......this CAN be posssible....but: I have no clue IF this is true or not (i mean the Name Change to "KSwheels") But i know that this is one Ali-Express Seller(named Rockwheel) is the most Kingsong selling one on Ali and some of the Forum members here are happy with their KS wheel's they got from him... Also i now that Ali-Express has a very strong counterfeit Money back garanty.... 1 Quote Link to comment Share on other sites More sharing options...
