04/07/2016 New! Chillafish BMXie-RS with airless RubberSkin tires Maybe you’re in need of a bike with tires that don’t need to be pumped, like, never ever in a lifetime? Guess what? At Chillafish, we figured out a way. No pumps, breakdown assistance or compressors. We used to say our BMXie was probably the coolest balance bike in the world. With its new RS-tires, it certainly is! Airless RubberSkin tires are a new kind of tires that give you the best grip possible, and you don’t even need to inflate them. A foam core means they cannot puncture; an outside rubber layer makes them just like rubber tires, unlike other foam tires on the market. Great grip – no pump – that’s best of both worlds.
