If you’ve ever been out enjoying a leisurely bike ride, only to run over a nail and get stuck with a flat tire, Britek has a solution for you. The company has developed a prototype for puncture-proof, airless bike tires that can store energy and convert it into forward momentum. The Energy Return Wheel (ERW) was originally developed for cars and is made up of an internal layer of rubber that is stretched across adjustable rods with elastic cushions in the middle in place of air and a rubber tread on the outside. The tires have 29″ carbon fiber rims with open sides that give them a light and sleek airy feel. The ERW makes for improved cycling performance and safer bike rides that won’t end in disaster.

You can see more pictures of the ERW and a video of the tires in action below.
