The Helium V4 is the ideal bicycle transport bag: air-cushioned, light as a feather and super easy to use. The bike can be stowed in the Helium V4 with minimal disassembly work, without having to adjust any components. It even fits into small cars without issues. An additional set of wheels, just like the helmet, shoes and other important utensils, easily fits in the carrying bag. There is no more comfortable and safer way to travel with your bicycle!
