Prevent punctures with tyre liners We love riding Super73's so much we've made our own tyre liners to help keep you cruising for longer. Tire Liners (a.k.a. Tube Protectors) shield against punctures from thorns, glass and road debris. Tyre liners provide a protective layer between the outer tyre and inner tube. They're made from lightweight and durable urethane. Urethane is design to make the liner tough when it needs to be, yet flexible enough to work with your Super73 tyre shape. When something small and sharp penetrates your tyre, the tyre liner protects the tube and helps to push the sharp object back out of the tyre. These tyre liners are designed to work with all models of Super73 eBikes and other fat tyre ebikes which have 20x4 or 20x5 wheels. They come in a pack of 1 so order 2 if you're fitting your whole bike.
