A true athletic build - Inspired by aerospace technology, our aluminium alloy frame is light and super strong. In fact, this Green Frame with Flashing Wheel Set is rated to safely support 136 kg. A true all-around athlete, the patented design of the ZUCA Sport demands attention. Agile, graceful, absurdly versatile. And with a light, super-strong aluminium frame and oversized polyurethane wheels (they climb stairs), even school hallways and cracked sidewalks can't slow its roll. Other sweet features? Wheels that flash and yes, a built-in seat. Ready? Game on.
