A YR Evolution is inspired by the Original family, from which it inherits the fundamental characteristics and advantages derived from the use of composite fiber.
The frame, Y Dynamic Frame, is made through the production process of lamination in an autoclave and the use of advanced composite materials loaded with Carbon Nanutubes, which give the monocoque frame mechanical properties of the highest level that allow the AYR Original to exceed the more stringent safety and resistance tests.
Carbon fiber, the absolute protagonist, gives the bicycle a natural cushioning that allows it to face the roughness of the road while maintaining high levels of comfort.
The Stealth Design gives the Evolution a unique line.
AYR EVOLUTION is powered by ZEHUS, the hub that allows you to move in lightness and freedom, helping your pedaling while maintaining an exceptional design: light, unique and captivating.
The completely invisible engine is equipped with an energy recovery system that allows you to never stop.
