The verge is completely wrong in this headline.
They wrote “are now available to buy”.
No. It’s a Kickstarter that might ship next year. The headline should have been “Bike tires made from NASA’s bizarre shape-shifting metal might be available to buy next year if the crowdfunding campaign isn’t a scam”

The second I see the words “kickstarter or indiegogo” I already know whatever I saw may as well be unobtanium
If it makes its way to a storefront then I’ll consider it, otherwise I’ll just move on and keep my money
Tbf if it’s indigogo, it’s a scam. If its funding is flexible, you might as well just throw your credit card into the trash bin. If it’s on kickstarter, you might at least get some product an few years late (or it’s just a normal pre-order with some extra steps and more expensive)
In this case it’s almost flexible funding. They set a ridiculous low target, $25k. That wouldn’t pay any tooling.
I never looked at their campaign, but did just read over it for fun. I didn’t do any further research and just assume no lying in the parts that can be checked without having knowledge about their specific products / industry.
First things first: It’s kickstarter, not IGG. It’s not using flexible funding (as that’s only on IGG, if they still allow it). They have a working prototype. That’s nice!
Having won all these awards is nice, but without knowledge about the specific awards, this information is useless. They seem to have a contract with NASA which gives them access to materials and technology. That’s a plus. They also seem to have a real working prototype.
$25k as a target is very low for product development. But they may be an established company and may get extra funding from other sources, so it might be a campaign to check the market and do some PR. Remember how I said many Kickstarters are essentially preorders? They’re not quite there yet in the product development cycle, but this might explain it with other funding besides kickstarter. But this should be researched further before backing.
The whole campaign feels more PR and sales as I’ve seen with the last campaigns that I actually backed (or at least checked because of an interesting “product”). I can’t help but it somehow reminds me of something…
Also after all this talking about space technology, they say it wouldn’t work on earth and needs to be adapted (so no space technology anymore, but still space technology?). I get that they need to do this and that its a bit unfair to point at it, but did chuckle when I read that. Especially when they continued talking about space technology right after.
I was wondering the whole time, whether their tires really last “the whole lifetime of a bike”. I usually change tires, because they’re worn out and the profile is low. Modern tires are quite good at preventing a flat. So the upside of this tire for me would be… no checking if I need to refill some air. They prevent this by making this part of the tire exchangeable (and if it works, $10 is fine as it’s still cheaper than a regular new tire). But then… it lasts the lifetime of your bike, but not specific parts of the product.
How easily can you get access to these spare parts after the campaign? How much trash are they really saving? And as they’re saying their approach is more environmentally friendly - did they research all the new materials used and their production?
So, for me it’s a product I wouldn’t back on KS. It’s a product, that would require me to get spare parts to be used meaningfully. It needs to be established on the market for that. Otherwise it’s nice in the beginning and then it was a waste of money.
Oh, speaking of money - I didn’t check yet how much id have to pay for a ti… WHAT? $500 for two of them? 2 Full wheels are starting at $1,300 and can be up to
$2,300$5,000 depending on your choice of material?!I can get a fully featured, brand new luxus eBike for that!🤯 Nah, not gonna happen. Talk about the environment as much as you like. A full set of good tires with anti-flat technology for my bike starts at around 40-50 bucks (non US, but shouldn’t be that different in the US?) and lasts a while. I can get 10 sets of tires for the price of this starter set and I’d probably get a few more when I have to pay for a few Tread replacements in between. Talk about the lifetime of a bike. LOL.
Maybe checkout crowdsupply. They have a 100% successfull fulfillment rate.

There have been solid, foam filled or gell filled bike tires for a long time.
The fundamental problem is that the ring of pressurized air in a pneumatic tire is a shock absorber. When you hit a bump the entire tire (even the part that isn’t touching the ground) contributes to the dampening because it turns into a shock wave in the donut of air. When you switch to any sort of tire that doesn’t have pressurized air in it, the dampening can only occur by deforming the tire in contact with the ground, and it’s not going to be anywhere near as good. Typically you end up with a tradeoff between uncomfortable ride on the one side, and bottoming out on the rim and lots of rolling friction on the other.
When you switch to any sort of tire that doesn’t have pressurized air in it, the dampening can only occur by deforming the tire in contact with the ground, and it’s not going to be anywhere near as good.
I mean, these new tires do deform with the ground. That’s the “revolutionary tech” they brag about; the rings are designed to compress a bit and deform to compensate for impact, but always bounce back to their original shape no matter how much force is exerted on them. So you get a simulated air pressure.
these new tires do deform with the ground
They aren’t saying they don’t. The foam and gel tires they mentioned also deform with the ground. Like you said, the rings only compress a bit at the site of the impact. Person you’re replying to is pointing out that pneumatic tires disperse this impact across the whole tire
I haven’t looked at the numbers, but I’m willing to give these a chance. If they can make tires that are almost as good as air ones but require less maintenance, they’ll be worth it for some people. If those metal rings aren’t too stiff, it should work.
These are street tires. Unless you weigh like 10kg the pressurized air isn’t doing much of anything for dampening.

And at only about 10 times the cost of traditional bicycle tires, you’ll only need to not replace your tires about 11 times for this to be cost-effective!
It might be worth it to not have to ever worry about having a flat.
I already don’t worry about that anymore using the anti-flat tyres I have on my bike. I can just ride through a pile of broken glass without a worry.
I’d probably still worry about falling over
No worries if you’re going fast enough. ;)
Thanks Newton!
Or if you know how to track stand.
Modern bikers use tubeless systems which don’t generally have flats. They are filled with a compound that plugs up holes as soon as they happen. You only get flats for large holes or sidewall punctures.
Do those actually work? I don’t have tubeless tires, but I haven’t had much luck with the liquid that you put in the tubes. In my experience, I still get flats, and the goo just makes a big mess inside the tire.
Maybe my holes are large? I regularly get flats from goat heads, and one summer I got a dozen or so flats on my work commute before finally buying Schwalbe Marathons, which seems to have solved the problem (have had like 1 flat per year since).
They work. I ride mtb downhill in a jungle and I haven’t had a puncture in ages.
Huh, maybe I’ll get those with my next MTB. Thanks!
Give it a decade and economies of scale, and maybe it will get it down to twice as expensive.
It’s a human feather.
Humans don’t have feathers.
Doigenes walks in in a feather boa.
Tyres last about a year, so this sounds fine

Yup, same. I bought Schwalbe Marathons a few years ago and haven’t needed new tires since. They’re kinda heavy and don’t ride as nice as other tires, but flats aren’t an issue anymore.
Either you bike a lot, or you use very thin tires. I bike occasionally, and I still have the original tires on my bike that I’ve had since I bought it in 2018, I think.
How do you get your groceries? How do you get to work?
Once per year is pretty typical for folks who use bikes.
For those I typically drive because there’s no good way for me to do it by bike. But I also put a few hundred miles on per year biking recreationally on a variety of surfaces.
So, yeah, you basically don’t use your bike

So you replace your tires twice/year? I do it like every 3+ years. Then again, I don’t race or anything, my bike is just for transportation.

I used to ride 20+ miles/32km per day, 4-5 days/week for my commute. Most of it was on an isolated bike path through the countryside, so not much glass and a lot more thorns.
I went from having a dozen or so flats in a few months to having pretty much none just by changing tires. If flats are common for you, better tires could probably help.
Regardless, I’m jealous of you being able to ride your bike that much. My current commute is just too far to commute by bike (it’s like 25mi/40km each way), so I end up riding like 1-2x/week just to the local store for groceries.
10 mins of internet relevance, a lifetime of obscurity and never being mentioned again
If we could all be so lucky.
Everybody pay attention to this guy for 10 minutes
Lost me at “the first consumer product we’re aware of to use nitinol”.
There were nitinol eyeglass frames back in the 1980s.
My handheld radio antennas are nitinol, I can bend them to fin in a bag or tie them in a loose knot and they don’t deform.
That they’re aware of?! This just reads like they didn’t bother to do any research.
Just use schwalbe marathon. They are puncture proof and last forever. I once got home and picked a shard of glass as king as my fingernail out of one.
…king?
I think he meant wing
Nah, must’ve been thing
My money’s on bling.

I do everything on a roadbike and fixed gear, which are claimed to have the highest risk of getting a flat tire.
I usually have 2 flats a year which cost around 6€.
I’m curious to see if this “no flat” tire will be cheaper and if it can be run tubeless.
Well, as to the last point the metal is providing internal rigidity, so that’s why there’s no inner tubing.
But agreed. I cannot see this trumping my replacement costs during my lifetime. It’s cool, and it might be more environment-friendly, but cost/benefit calculation says no.
Pretty sure this was on US Dragons Den and it got laughed out due to the cost. I’m like, yeah cost is pretty high initially but when the hell we gonna move on from rubber?
You do realise that stuff grows on trees, right?
No, I thought it was made from the crack of yo mama’s ass
You do realize harvesting rubber from trees means lots of cut down trees in the Amazon, and most rubber in tyres is actually synthetic
I do know most rubber is synthetic, but even making it from fossil fuels we will have enough that we will never run out.
Uh, not if our fossil fuel consumption drops to 0, which is where we will need to be
There is still rubber even with these.
Despite all of the “this is new” in the article, nitinol has been around for a long time. I have a great set of small split rings made of nitinol from at least a decade ago. Wish I could get more of them.
I hope they are not called T(ires)1000 :)
That would be a pretty funny movie if the terminators were all bike tires.
Get the star of the movie Rubber to play all the parts like a Eddie Murphy movie.
And it can be called “The tireminator” :)
100% a scam.
No one is ever getting a product from this.
Wonder if they’d work as skateboard wheels, that’d be pretty sick
Dude! Those are the first step to getting the skate wheels from Snow Crash!
Looks heavy.
The Kickstarter page puts it at 450g, which seems to be fairly good compared to the first tire I googled’s ~600g.

It’s lighter because instead of compounds inside of the tire, there is air.
