Very cool dude!

I really did not understand the washer part and why you needed to add those three washers but very interesting alternative and i have a strange feeling what u purchased may be better than ninebot one's stock (at least with the liner)

Question: how much was the price of the tube? (compared to the one they're selling online, was it cheaper?) how did u find the right size at a local store? is it a standard bike size?

Very cool that you got the dissemble part down. I hope i could fix mine in the future too

@patrickrho - Good question

The standard inntertube was only about $4 from a bike shop. No where near the asking price of the ninebot inner tube.  

Regarding the washers - the standard inner tube airvavle stick out a bit too much so it can potential - (and maybe not) rub against the body the shell of the ninebot. In order to reduce the amount the air valve sticks out i added some washers to the rim side of the valve. That way it doesn't stick out as much because the washers are in the way. I hope this helps.

This is potentially the best bit of advice for non-newbies on here!

@Kroy thank you! Trust me i drove to every bike shop in my area looking for an innertube with a bent air valve with no avail, finally decided to be creative. So far so good no issues as of now.

@patrickrho - to answer your question the ninebot tire size is about 16 inches. The bike inner tube was about 16 x 1.25 or something along those lines. The even had 16" tires for those who want to change it out. I might be doing so next.

Thanks for the information! 

Im sure this sort of information will serve the community well like Kroy mentioned

When you get a puncture on a ninebot one, is it always the inner tube that needs to be replaced? Is the tire OK to be reused?  Say a needle goes through the tire and through the inner tube, then you would just need to replace the inner tube?

@patrickrho - It really depends - I use to do  a lot of bike riding - usually when the inner tube is punctured that mean something went through the tire and hit the tube. You can res-use the tire with no issues. The inner tube would just have to be patched -tube patch kit is a kit that is sold at all bike shops for about $3.00. That way you dont have to run out and purchase a new tube. It's rare to just go out and by a brand new tire unless you can actually see the hole.

 

Hope this helps!

My concern with metal washers would be that it would affect the balance of the tire when you're at speed, leading to vibration. Perhaps you could cut up the old tube and use some pieces of rubber as spacers? You're right about the crazy cost of these bent-valve tubes though, a new one for my 14-inch EUC cost $20! In my case it was a weakness in the original tube and not a puncture, after patching it once I gave up and just replaced it.

@dmethvin - You know what i didn't think about that, I rode to work this morning and did not feel any vibrations although its probably because i wasn't looking for any. I'll observe my ride on my way home and report, good observation!

 

Its funny you say that I thought the same thing there's already a whole - It's weak at this point. The last thing I want is to be far away from home get a flat and have to carry it all the way back that's why i decided to just purchase a new inner-tube.

 

And yes $20 for an inner-tube is absurd!

I doubt the washers have enough mass to cause any noticeable vibrations (people have bike computer magnets attached to the rim, which probably weigh more), but of course could be wrong... The riding speeds, and thus, rotational speeds on EUCs are much lower than say a motorcycle or a car, where the tire balancing probably matters much more (in higher speeds).

the drone vid is friggen cool! B)

I loose air very slowly, gotta refill my tire every 1.5 weeks so I will be looking at a tube replacement soon, thats good intel thanks @Tishawn Fahie , I will ask the bike shop if they can bend the valve, they got 5 tries before it gets more expensive than a ninebot tire :lol:

Thanks for confirming about the washers yeah i'm not to familiar with wheel balance. I know for sure riding in I didn't feel anytime of vibration.

 

@Jag_Rip - Haha your so right! I didn't even think to ask them to bend the valve, shouldn't be a problem. And thanks yeah i'm just testing different scenarios with drone recording!

@Gil - I actually saw that product - I ran through various forums and while some swear by the slime solution, most people went with the tire liners for some reason.

Why can't you just buy a bent valve wheel on Amazon?  They run about $17 U.S. I would strongly recommend buying the Heavy Duty version of this tube. I've tried many others and always seem to replace them.  I don't know if it's the Heavy Duty or the next  product I discovered but the combination of the two works great!  

Or, you can buy Stan's Tubeless solution which comes in like a 2oz bottle for $5.  That stuff I would HIGHLY recommend everyone put in their wheel.  It reseals the tire when a puncture occurs, immediately.  I've driven through glass and heard it puncture several times and air start to drain from my tire, then it just stopped. Stan's is the bomb!  I tried Slime several times and it just didn't seal my tire, and was VERY messy.  Also tried fix a flat which ruined my tire.  

Here's a link for both:

How is a bent valve made ? Because it does look a bit like they just got a standard inner tube and a massive pair of pliers, and went from there. There is a definite crease on both my wheels where the pipe has been bent, suggesting it isn't something manufactured in, or bent nicely round some sort of forming device - so my question is - how easy it to bend one of these things yourself ? I guess if a standard inner tube is only $7 it won't cost too much to find out...

This is one area where Solowheel got it right, and nobody else has - their valves are just shorter and straight, so fit without having to bend anything.

Anyone know where we get those from ?! :)

Bought some tubes from ebay. And when they came the tubes were pointing the wrong way.

Doesn't that simply depend on in which direction the tube is mounted? Turning it by 180 should make it point to the right direction, no?
