on my 18L I sometimes are lifting it while handle fully extended... Seems to be ok... Also it has the latest version on handle (the black one).

Yes @Chriull is right ! KS18L/XL is very easy to operate... but you need to remain humble to avoid a faceplant... You must really think to never push your EUC to its limits... Especially if you are not wearing full protections.

Well here it is: https://fccid.io/2AQAN-KS-18L/User-Manual/User-Manual-3917495.pdf But to be honest EUC are so simple (one button only) that you probably do not need it... Moreover lot functions can only be setup from mobile app (use "EUR world" instead of KS original app). Enjoy !

Well it's like for a motorcycle... it's 50km/h max but all kids know how to upgrade... Same here, I don't really see how you can limit "hardware" speed on EUC as all is done in firmware... So it can be always changed, modified. You know that KS can lock speed in their official app, as you have to login to unlock higher speeds. So it's probably registered somewhere on their servers and linked to serial number of your EUC. So if you use official KS app, they can easily lock speed settings to max 25km/h... But it will be always easy to overwrite using an unofficial app or by flashing firmware... just like for a motorcycle... :-)

@Jack King Song thank you for your patience and hard work ! Really appreciated !

On their site it says: " "Vitesse Maximale 25 km/h (débridable 40Km/h pour pistes privées)" So I guess is something like: "seller sets app speed to 25km/h then change password and sell it as factory speed limitation"... Easy-peasy to unlock...

So with this new KS my dream of riding full speed on some Parisian streets, will become a reality :-)

This never happens to me since I have this wheel... (almost 2 years). It looks like a firmware crash... And now I'm worrying it can happens to me too so I will charge it only while on its side... Also it's the first time I hear about this kind of issue...

Let us know, please ! It's interesting to check the real speed as KS app is apparently overestimating it !

yes... It's just hard to belive they are keeping this 'error' for such a long time without any fix... It almost looks like they a not making any difference between 18/16 wheels. Is the error the same on 16x ? Also right for relative error, I was just saying that this kind of error should be more visible on 10km ride then on 1km ride :-)

@Seba don't you think that this difference is somehow linked to tire pressure ? My is 4 bars (as instructed in KS18L manual). Also most people are riding at around 2.5 bars. I think couple off millimeters less on the wheel diameter can explain this on a longer run...

@Seba, do you think it's possible to add a function that will call periodically a url with some parameters like charge level, voltage, current ? A lot of houses there a including home automation systems, and this the easiest way to interface with theses controllers (Jeedom, Vera, AutoHome, etc)... All plugs and all lights in my home are driven this way...

sounds a little bit complicated and honestly it's pretty rare they do it for scooters so i'm not sure they will bother themselves to do it on EUC...

What if you setup a limit at 25km/h with KS app ? Who will test it ? Is police able to check the speed (actually use the wheel) ? What if you setup a password in the app ? Who can then test the real speed of your wheel and even connect with the app and change settings ? In France is also limited to 25km/h and we have 1 year to make our EUC compliant before it cost you 1500 Euros. I use my KS everyday to commute to my work place and I just setup an alert at 25 km/h, double beep at 30km/h and tilt-back at 35km/h... As far no one cares if i respect road signs, lights...

Updated ! For now it's awesome ! Will test it more on my way back from office.
