It’s the weekend, and you are finally precisely where you want to be—loading up your bicycle and heading to meet up for a group ride with the boys. Whether riding on a road, mountain biking, or something in between, you are cycling, and that is all that matters.

Then, it happens a major mechanical issue. You have a flat tire. Your friends now stand around as you fumble with tubes, pumps, and patch kits. You try to get your tire rolling again, all the while knowing you’ll never be able to get your bicycle tires back to proper inflation without a floor pump.

Or, perhaps worst of all, flat tire repair is nowhere to be found. Your group carries on as you push your bicycle back to your vehicle. 

Wouldn’t it be nice if you could head out cycling without worrying about getting a flat tire? What if flat tires were a thing of the past? It would at least be one less thing to fuss about regarding your bicycle. 

Well, this reality might be closer than you think. And if you feel like indestructible bike tires could only be the work of someplace like NASA, you’d be right.

Instructables bicycle tires 

Now, we have yet to see NASA sending a bicycle into space, but we certainly look forward to tire tracks on the moon. What NASA has been doing for a rather long time is putting vehicles—manned and robotic—on places like the Moon and Mars.

As you can imagine, Mars is the last place you want flat tires. So, NASA set out to eliminate that potential. 

Fast forward to 2020, and The Smart Tire Company (STC) was founded in hopes of finding commercial uses for NASA’s tire technology. Among these uses is the company’s new METL bicycle tire.

STC gets its name from the process used to make its METL tires or Shape Memory Alloy Radial Technology. This “SMART” tire is made of a superplastic material known as NiTinol+. NiTinol+ doesn’t stretch to absorb impacts rather it temporarily rearranges its molecular structure before instantly returning to its original shape.

METL bicycle tires are airless; therefore no flat tires ever. STC boasts that they are the “first-ever pneumatic bike tire alternative to achieve a lightweight, smooth ride, with superior handling and durability.” 

Although not fully released yet, the final product will have a special integrated poly-rubber tread pattern meant to last a rider the life of the bicycle. No punctures, no tears, no flats, no problems.

And while STC’s website only teases at what looks like a road bike tire, the site lists quite a few specialty tires, including gravel, mountain biking, and commuting.

As of now, the price of STC‘s METL bike tire is unknown. But they told consumers to expect a premium bicycle tire rolling on a high-end wheel. We’ll know more as far as price, weight, warranty, etc. as the release date gets closer.

For now, if you are interested in your own indestructible NASA bike tires, plug your information into STC’s 2024 waitlist. You can find all their information on their website.

Lake Tahoe is one of the finest natural wonders of the world. From its vast blue expanses to its surrounding peaks, the lake is a magical, scenic destination. And with world-class mountain terrain on offer, skiers and snowboarders are in for a seminal experience. Not only that, but since Tahoe’s a reasonable distance from the Bay Area and Reno-Tahoe International Airport, getting there’s as easy as jumping in the car or hopping on a flight.

The ultimate ski gift guide for anyone who loves powder days

It’s about that time of year again, The Season of Giving. Gift-giving has, without failure, been an Achilles Heel of mine, mainly because I procrastinate -- just waiting around for the gift of all gifts to just plop right down before my eyes. It’s never happened, and I don’t think it ever will.

What follows is hours of Googling and awkwardly vague phone calls with friends and family about their hobbies and interests that sound a little like, “Hey, Dad! You still doing [insert interest or hobby]?” This process usually culminates in a rushed gift-buying process that can be super hit-or-miss.

Après ski is cool, but the Swedish tradition of fika might be cooler: Here’s why
Apres ski and fika, a match made in heaven
Coffee cups cheers-ing

We all love the occasional après ski. The feeling of unclipping the boots, ripping off your helmet, and taking a deep exhale next to a roaring fire as you wait on a refreshing beer is unparalleled. It’s as much a time to relax and unwind as it is to catch up with buds that you may not have seen in a grip.

But what if I told you the Swedes have been brewing a tradition with similar vibes as après ski for the greater part of 100 years? Only, not for the slopes, but for the workplace. Keep reading to learn about the fika meaning.
