The Gibbs Quadski is a revolutionary high-speed amphibious vehicle that combines the freedom of an all-terrain quad bike with the thrill of a personal watercraft—all in one dynamic, shape-shifting machine. Designed and engineered by Gibbs Sports Amphibians, the Quadski is the world’s first sports vehicle capable of reaching impressive speeds on both land and water, seamlessly transitioning between the two in under five seconds.

A true innovation in recreational mobility, the Quadski unlocks new possibilities for outdoor enthusiasts, adventurers, emergency responders, and thrill-seekers alike. With powerful performance, cutting-edge design, and rugged durability, it delivers the ultimate freedom to ride, splash, and explore anywhere the terrain takes you—no trailer required.

Dual Terrain. Single Machine. Limitless Possibilities.

The Quadski is a marvel of engineering, utilizing Gibbs’ patented High-Speed Amphibian (HSA™) technology to switch between land and water modes at the push of a button. On land, it handles like a premium ATV, and on water, it becomes a smooth, responsive jet ski—allowing riders to drive straight into a lake, river, or ocean without stopping.

On Land:

• Speeds up to 45 mph (72 km/h)

• Rugged 4-wheel suspension and off-road tires

• Comfortable, sporty handling for trails, sand, mud, or rocky terrain

On Water:

• Speeds up to 45 mph (72 km/h)

• Powerful water jet propulsion system

• Streamlined hull design for smooth gliding and tight turns

Transitioning between land and water is as simple as slowing down near the shoreline, pushing a button, and letting the wheels retract into the hull. Within seconds, the Quadski becomes fully amphibious—no complex prep, no towing, and no wasted time.
