The Smart Tire Company has unveiled its new Metl bicycle tires, which are the first consumer product to utilize nitinol, a shape-memory alloy developed by NASA. Nitinol is a nickel and titanium alloy that can be trained to remember its shape through the application of heat. The Metl tires are designed to be durable, never go flat, and last a lifetime.
Compared to traditional bicycle tires, the Metl tires provide superior durability and longevity. They are being sold through a crowdfunded campaign on Kickstarter, and a pledge of $500 will get you a pair of blue or clear Metl tires. The installation is “DIY easy” and compatible with most common road or gravel bike rims.
The Metl tires come with an integrated all-weather tread that offers “medium low” rolling resistance. The tread is rated for up to 8,000 miles and retreads are available for $10 per tire. Despite their memory-metal construction, the tires provide grip and traction, offering a smooth ride with superior handling.
The estimated delivery for the Metl tires is listed as June 2024, and the Kickstarter campaign has already exceeded its goal with 128 backers. Stretch goals include the production of wider Metl tires for e-bikes and mountain bikes, as well as additional sizes and tread patterns for road and gravel bikes.
Crowdfunding campaigns can be unpredictable, so it’s important to exercise caution when participating. It is advised to assess the legitimacy of the product, check if there is a working prototype, and determine if the company has a history of successfully delivering on its promises.
Overall, the Metl bicycle tires offer an innovative solution for cyclists seeking long-lasting, flat-free performance. By utilizing nitinol, these tires provide a durable and reliable option for riders.
