A true all-around athlete, the patented design of the ZUCA Sport demands attention. Agile. Graceful. Absurdly versatile. And with a light, super-strong aluminum frame and oversized polyurethane wheels (they climb stairs), even school hallways and cracked sidewalks can't slow its roll. Other sweet features? A removable hand washable bag. Wheels that flash. Tons of custom combos. And yes, a built-in seat. Ditch the back pack and travel in style and ease.
