Gibbs Quadski


The Gibbs Quadski is an amphibious quad bike/ATV, launched in October 2012 by Gibbs Sports Amphibians.
The Quadski is a 4-stroke, amphiquad that converts to a personal watercraft. It features a top speed of on both land and water, a proprietary marine jet propulsion system, and wheel retraction. The Quadski can transition between land and water in about five seconds. The Quadski uses Gibbs' High Speed Amphibian technology, which includes more than 300 patents and patents pending worldwide.
Developed and manufactured by a Detroit-based team, the Quadski shares a number of features with the Gibbs Aquada. When entering the water, by pressing a button the driver can retract the wheels into the wheel wells within the vehicle’s body and detach them from the drive train.
The Quadski uses a marinised version of BMW Motorrad's 1.3-liter engine from the K1300S. In the K1300S, the engine produces, but Gibbs advertises for the Quadski. Power is further curtailed to about when in land mode. On water, the Quadski uses a stoneguard-protected intake, which draws in water before directing it through the engine-driven impeller, which, with the stator blades and nozzle, propels the Quadski at high speed. The steering nozzle at the Quadski’s rear directs the vehicle via the handlebars.
The Quadski allows for over two hours travel time on the water. Its range on land is up to around. It went on sale in January 2013 in Florida and is now available in selected regions of the United States with a starting price of about $40,000.
