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)

[–] [email protected] 3 points 1 year ago (1 children)

In this case it's almost flexible funding. They set a ridiculous low target, $25k. That wouldn't pay any tooling.

[–] [email protected] 3 points 1 year ago

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.

Available to buy, not to have. Hah

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.

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.

[–] [email protected] 30 points 1 year ago

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

[–] [email protected] 4 points 1 year ago* (last edited 1 year ago)

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.

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!

[–] [email protected] 27 points 1 year ago (3 children)

It might be worth it to not have to ever worry about having a flat.

[–] [email protected] 5 points 1 year ago (4 children)

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.

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.

Give it a decade and economies of scale, and maybe it will get it down to twice as expensive.

10 mins of internet relevance, a lifetime of obscurity and never being mentioned again

Lost me at "the first consumer product we’re aware of to use nitinol".

There were nitinol eyeglass frames back in the 1980s.

[–] [email protected] 8 points 1 year ago

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.

[–] [email protected] 7 points 1 year ago

That they’re aware of?! This just reads like they didn’t bother to do any research.

[–] [email protected] 13 points 1 year ago (1 children)

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.

Zing you peasants

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 usually get a new pair of tires roughly once a year "just to be safe" when i notice the rubber showing oddities or they start losing grip a little. I usually go for continental GP (4kII/5k) tires if they are discounted and pay roughly 80€ for a pair.

I'm curious to see if this "no flat" tire will be cheaper and if it can be run tubeless.

[–] [email protected] 4 points 1 year ago

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.

[–] [email protected] 4 points 1 year ago

I don't believe they have air in them but I'll believe the claims when I see it.

Other note. Tannus tires are fine if you want that sort of thing.

[–] [email protected] 8 points 1 year ago

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.

[–] [email protected] 6 points 1 year ago* (last edited 1 year ago) (3 children)

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?

[–] [email protected] 7 points 1 year ago

There is still rubber even with these.

[–] [email protected] 6 points 1 year ago (4 children)

You do realise that stuff grows on trees, right?

People these days pay more for bike tires than car tires these days already. There are $10k bikes now. Seems there's no amount of money some people won't pay for bike parts these days.

[–] [email protected] 4 points 1 year ago (1 children)

I hope they are not called T(ires)1000 :)

[–] [email protected] 5 points 1 year ago (2 children)

That would be a pretty funny movie if the terminators were all bike tires.

Wonder if they'd work as skateboard wheels, that'd be pretty sick

[–] [email protected] 5 points 1 year ago

Dude! Those are the first step to getting the skate wheels from Snow Crash!

[–] [email protected] 3 points 1 year ago

100% a scam.

No one is ever getting a product from this.
