Personally I've always preferred them natural ;-)

Haha , me too , interesting how quick money can turn scientists and doctors into criminals , and how sexy models pornstars turn everything into a horror movie , they are full with botox , silicone and alot of other shit  :blink1:

What type of cleaner is this? Is there a website about it? I could not find any information.

T-Röd - 50-75 % Etanol, 10 -< 15 % Propan-2-ol, 5 -< 7,5 % Butanon och 1 -< 2,5 % Aceton[1]. , 1 litre , they call it T-Red "T-Röd" and sell it in gasolin stations , supermarkets ,
it is with flavour bad taste so no one drinks it 

I only find the info in Swedish

@OliverH

no, we have last Time a KS16 here for repair....it was under water and has around 150ml Water inside motor...you can drive all works but bearings make extrem noise

the motor is original enough sealed and when you drive you have centrifugal force... in past time we have no motor + water problems

I agree with the centrifuge force but in large amounts everything counts , it's like bying a lottery ticket , water and electronics is not so good together and most of the wheels out there has no sealing at all , I don't play russian roulette with a possible faceplant and broken arms that's why I rather keep water on the outside of the motor

Yes, your additional sealing is not bad but i mean not necessary...

water inside motor and faceplant is near 0% chance

The faceplant chance is with only one real mosfet set, one hall sensing circut, one +5V logic power many times greater than water inside motor faceplant chance...

That is work for future...more safety in the controlling and power output stage

but not misunderstand your sealing is good! but also seal from no water can go out when in..water can comes in to the center hole from axle and can never go out....good seal have every time both problems.... ;)

But i never have seen a Motor with water inside in normal drive conditions....and many user's drive it realy hard in snow and rain..near under water;)

 

And the unprotected KS16 Mainboard was complete under water switched on, batterys BMS was corroded and we have only replace the BMS..cells self nothing bad...and this wheel drive with same hardware...every day...

 

Have you open the motor? it is sealed from factory between the flat surfaces from cover's and motor self...the Motor is from Factory 100% sealed

pls do not open with experience... many magnet force...magnet's lift all metal parts from work area in the motor...attention

I have seen images from an opened gotway motor and it had no sealing and I opened a cheap noname model and that did not have any sealing either  , its like a mobile phone , theres a reason why new models are waterproof , they would not build electric cars that cant stand water , I even heard about electric motorcycles that stopped in rain and were useless afterwards ( I bet China won't sell more of them here in this area), water is a big nono and just because you found some that worked it's only a matter of time before something happens , there is a sensor circuit inside the motor and it is probably unprotected   ( i hate stupidity , if I have opened a certain wheel or not is not important in this matter)

If the axle takes in water then it's time to do something about it

A Flash thoughts , newer surrender when you know your'e right   B)

In our region some guys ride the whole year. I prevent riding in rain/don't ride through puddles and do not ride on snow, because I don't trust the way EUCs are build by today (I don't use the sentence engineered).

Hall sensors are in the outer space of the stator. This with the cable (HALL/ phases) and the small PCB  inside the motor for the HALL sensors are prawn to be a reason to fail with water inside. I'm not sure if coating can prevent all short circuiting with water inside.

This motors do not have high IP water resistance ratings in real life. The bearings are shielded but not having an axle sealing (Simmer-Ring). So if an EUC is dropped in water by accident you can get excessive oxidation inside the motor. The water will damage the bearing (grease/ water emulsion, loss of lubrication).

I still have a KS16 on my workbench to investigate the problem (not done since last autumn, shame on me). I need to look inside the motor and check the HALL sensors. The motor side covers to the rim will be sealed by this occasion. 

This post is not blaming KS it's a statement to all manufacturers. There are small differences reacting on quality issues but no one has a quality system in place.

@Flash your Monty Python "argument " sketch video was priceless.  Sometimes it feels like that on here, and with my current partner.  I must emphasise "current" but soon to be former ?
