The SMART Tire Company is working on an airless tire design for bikes that takes its cues from technology developed by NASA for space rovers. While the prototype pictured above is clearly road-focused, the company says their METL™ technology “will be available on mountain bikes.”
According to a recent press release, “the shape memory alloy 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 without ever going flat.”
SMART has partnered with Felt Bicycles as part of their testing and development, and the company eventually hopes to provide solutions to the auto industry as well.
