SMART Tire Company & NASA Announce First Space-Age Alloy Tire

For over thirty years, we have strived to be the most innovative cycling company on the planet. That’s been our guiding principle. So we're thrilled whenever we have the opportunity to partner up with some like-minded organizations who are dedicated to experimentation and advancing technology, and who refuse to be constrained by all that's come before. The SMART Tire Company is one such organization. We're proud to support their efforts in adapting a revolutionary, space-age tire technology for cyclists. Their metal-based, airless tires are unlike anything else in the world.

Eric Sakalowsky, Felt's VP Global Marketing & E-Commerce, said, "The SMART Tire Company’s tire solution shows an exciting new frontier, and we’re excited to offer our bikes to support their testing."

What makes SMART's tire technology so unique? Read on to learn more about this exciting new technology in the official press release from SMART. We'll be sure to update you as our friends at SMART continue to develop this exciting technology.

Press Release—The SMART Tire Company, in partnership with NASA, is developing the first ever consumer application of NASA's shape memory alloy (SMA) tire technology, a cutting edge, eco-friendly bicycle tire called METLTM. Originally invented by NASA for use on lunar and Mars rover missions, the SMA tire is made from advanced, lightweight materials known as NiTinol+, creating a tire that is elastic like rubber yet strong like titanium, exhibiting perfect shape memory while never going flat.

Made in gold, silver and metallic blue, the SMART Tire Company’s METLTM bike tire has a stunning, space-age metallic look and feel. “Cyclists won’t be able to wait to get their hands on these very cool-looking, space-age METLTM tires that never go flat,” says Earl Cole, former Survivor winner and CEO of The SMART Tire Company. “The unique combination of these advanced materials, coupled with a next generation, eco-friendly design will make for a revolutionary product.”

The SMART Tire Company LLC was founded in 2020 by Cole and blockchain engineer, Brian Yennie. Together with former NASA engineering intern and cycling enthusiast, Calvin Young, the SMART team has consulted with NASA Glenn Research Center inventors Dr. Santo Padula and Colin Creager to bring the power of shape memory alloy tire technology to the general public. Thanks to their ability to undergo phase transitions at the molecular level under strain, SMAs are unlike any other material, exhibiting thirty times the recoverable strain of ordinary steel. What’s more, SMART’s METLTM tires are eco-friendly, long-lasting and practically maintenance free. SMART’s advanced research will establish METLTM tires as the premier high-tech component for the modern cyclist across road, gravel, mountain and e-bike applications.

“Shape memory alloys look extremely promising in revolutionizing the entire terrestrial tire industry,” says Santo Padula, PhD, Materials Science Engineer at NASA, “and that’s just the tip of the iceberg.”

The SMART Tire Company is taking on the $250B global tire market in hopes of becoming the next great American tire company, bringing smarter and cleaner solutions to the future of transportation .

BIKE SIZING

Getting the proper size bike is key to comfort, performance, and safety. The world's best bike, if the wrong size for you, won't make you a better rider.
Our bike sizing guide is meant to give some general direction as to the best size to fit you based on your height. This is just one variable in a very complex system between rider and bike so keep in mind that rider proportions, fitness levels, and other aspects particular to the individual cyclist has a big impact on how you'll feel and perform on your new bike. Our size guidelines are not a substitute for a professional bike fit. If you have size questions, please don't hesitate to visit your local qualified bike fitter or reach out to us.
