How to waterproof KS18L?

Recommended Posts

Hi guys,

After having looked at the disassembly video, it looks clear to me this beauty is not waterproof. I wonder in what desert is engineers live, but anyway I, for one, leave in Belgium where it does not rain only ?.

Possible points of water entry identified: side leds, side panel edges, speakers.

My wheel is rubber black, any idea how to seal all of this without affecting aesthetic and keeping it easy to repair?

No wheel is waterproof, but until we don't try to ride underwater, it's OK if our wheels are just weatherproof & splashproof :) Believe me - this wheel won't be damaged by riding over puddle or in rain, even heavy. Critical parts are sealed with special coating (controller board, BMS), other are also protected from water ingress. Small amounts of water ale allowed to enter via speakers or other holes. They will just drain down without any harm to your wheel.

Yes KS18L is really well made wheel. Battery is well protected, and the main board is on the top, far away from where the water can get it. If you are not planning to swim on it, it should resist heavy rain. Also I will more worry for the motor, as in some old version of KS wheels the water was able to get it. But they probably fixes it since a long time. @tinawong Any idea if there is any gasket that seal and protect motor from water going in ?

My bad, gents, I meant weatherproof obviously.

If you look at the led connector or trolley sensor at the bottom of the wheel, they don’t look so much protected to me, what do you think?

I think they are enough protected from rain, but as said you can't put the wheel is plain water.

Actually that's a good question.

Just FYI: If water gets to battery cells somehow, the wheel is VERY likely to catch fire, not immediately, but with 12+ hours delay.

There was a case in Russia where a guy sunk his KS14s 840 in a pond. He then disassembled it and removed the water (he thought so), but the wheel still caught fire at night, thankfully no deaths, but his apartment was heavily damaged.

And 18L has a design feature that can be dangerous in some curcumstances: its battery boxes are flat and long, and the lowest cells hang very low, just above the pedals. Just yesterday a guy from Belarus accidentally got on an 18L into a puddle which reached the tops of his shoes. He was advised to disassemble and check his wheel immediatlely, the outcome is still unknown.

Even without ponds and knee deep puddles, I've seen dust in an opened 18L at the level higher than the lowest battery cells. That raises the question: can the wetness reach the batteries from the bottom even when just riding on shallow puddles? I'm not sure the battery boxes are waterproof except just the closed plastic box.

Besides that, I guess the only other question is isolation of the wheel compartment. Is it waterproof enough from the factory?

All the rest is protected by a plastic bag or a waterproof backpack cover put on the wheel's top, which is always a good idea in a considerable rain.

I rode my 18l through some 2 inch puddles after it rained with water following the tire tread and being thrown in front of the tire. No issues. Mud flap works great too!

Actually this „design feature“ is on a lot of wheels...RW GT16, KS18S, Gotway Monsters....

Driving into a puddle which goes over pedal height is a bad idea at all....i also would directly inspect the internals. (on all wheels, some other might have their motherboard down there)

The motor rim where all the screwas are is normally extra protected by some silicon....

The danger is more coming from where the bearing and the axle are. There the wheel is not waterproof!

Even if you sink a motor just for some seconds....you can be sure water is now inside and doing its rust job.....

On KS18L they put some silicon when the motor cable is entering the axle.
