Are you tired of having to replace your bike’s tires or them losing air over time? Meet the Airless Bike Tires. These are designed by Brian Russell to eliminate the necessity of air in tires. You won’t have to worry about punctures, tube replacements, and pressure checks. Instead of air, these use rubber stretched over carbon nano tube reinforced composite rods to get you going. You can change the rubber’s tension depending on where you want to take your bike. Pretty exciting concept if you ask us.
