Sports Amphibians

Boundless Freedom

Gibbs Sports Amphibians, the pioneering global leader in High Speed Amphibian (HSA) technology, introduces two innovative amphibians - the Quadski and Quadski XL - that redefine the ideas of freedom, flexibility and fun.

Powered by the BMW Motorrad K1300 engine, the Quadski is capable of attaining speeds of 45 mph on both land and water. The performance and comfort of the ride are the result of a lightweight composite hull, wide track and low center of gravity, which gives the Quadski stability on land and water. The most advanced piece of Gibbs engineering is the suspension. It gives a superb ride and handling on land and retracts when on the water. The complete transition takes under five seconds, at the push of a button. Incorporating Gibbs High Speed Amphibian technology, the Quadski hull provides a stable planing surface and lateral stability for responsive handling on water. The proprietary Gibbs jet drive is lighter and more compact than traditional marine industry water jets and provides high levels of thrust and maneuverability on water, propelling the Quadski to planing speed in seconds.



The Quadski ushers in a new era of thrilling, go-anywhere recreation. You no longer have to choose between trail and water, opening up opportunities to explore like never before. Climb on, feel the freedom... and leave the boundaries behind!


A true amphibian, the Quadski is equally agile on land and water. A simple touch of a switch retracts the wheels after entering the water and deploys them when approaching land. The transition is quick and easy, allowing you to enjoy an exciting experience in either environment.


Riding the Quadski is a unique and exhilarating experience — one that indulges your sense of adventure. Capable of reaching speeds of 45 mph on both land and water, the Quadski delivers spirited and stable performance. From trailhead to beachhead, you are propelled onto a ground-breaking level of fun and excitement.

Manufactured in Auburn Hills, Michigan, the world’s first high speed sports amphibians enhance the freedom, flexibility and fun of personal powersports while eliminating the need to compromise between land and water.

BMW Engine

A powerful and efficient BMW Motorrad K1300 engine is the heart of the Quadski and Quadski XL. BMW’s durable but lightweight power plant produces up to 140 horsepower and enables speeds of 45 mph on both land and water for rousing, one-of-a-kind ride experiences.


The Quadski’s revolutionary retractable suspension provides a nearly-seamless transition from performance ATV to a wheels-up personal watercraft in less than five seconds. The robust, but lightweight aluminum-alloy suspension delivers protection from the elements, while providing an exhilarating ride on both land and water.

Composite Hull

Ride performance and comfort are the result of the Quadski’s lightweight composite hull, which delivers a solid planing surface and excellent lateral stability for responsive control on water. In land mode, the wide stance and low center of gravity give Quadski and Quadski XL a smooth, surefooted feel and nimble handling.

Jet Drive

The Quadski and Quadski XL feature a patented water jet drive that is lighter and more compact than those found on a typical personal watercraft. This inventive design provides high levels of thrust to reach planing speed in seconds, along with outstanding maneuverability in a variety of on-water conditions.
