"Get Your Hands on NASA's Shape-Shifting Metal Bike Tires Today!"
The Smart Tire Company, a former Shark Tank contestant, is offering Metl bicycle tires made from NASA-developed nitinol, a shape-memory alloy. These tires promise to never go flat and last a lifetime. Sold through a Kickstarter campaign, the tires are priced at $500 for a pair and offer a lightweight, smooth ride with superior handling and durability. The campaign has already exceeded its goal and stretch goals include wider tires for e-bikes and mountain bikes. However, caution is advised when backing crowdfunding campaigns as there is a risk of delays or unfulfilled promises.
