They create a bicycle tire that will never go flat using NASA material.

Nitinol is an alloy of nickel and titanium that has the property of remembering its original shape after deformation and heating. The name nitinol comes from the acronym Ni-Ti-Naval Ordnance Laboratory, the place where it was discovered by William Boiler in the 1960s and developed POT to create spatial inputs.

Metl’s bicycle tire is the first consumer product we know of to use nitinol.

Compared to traditional bicycle tires, Metl tires will never flatten out and last a lifetime, or so Smart Tire promises.

Despite the metal construction with memory foam, the tires provide traction thanks to an integrated all-weather tread that offers “medium-low” rolling resistance, according to the campaign. The tread is designed to last up to 8,000 miles.

Metl bicycle tires are said to provide a “light and smooth ride, superior handling and durability” and can also “increase traction” compared to conventional inflatable tires.

Estimated delivery of Metl bicycle tires is scheduled for June 2024. The campaign currently has 128 supporters, reaching its triple goal, with 28 days left to go.
