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 can attain a top speed of 72 km/h (45 mph) on both land and water, and features a proprietary marine jet propulsion system as well as wheel retraction, allowing it to transition between land and water in about five seconds.

The Quadski driving on land

Developed and manufactured by a Detroit-based team, the Quadski shares a number of features with the Gibbs Aquada. It uses a marinised version of BMW Motorrad's 1.3-liter engine from the K1300S, developing 140 bhp (100 kW), although power is further curtailed to about 80 bhp (60 kW) when in land mode.[1] 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. On water, the Quadski uses a stone guard-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 and its range on land is up to around 600 kilometres (370 mi).

Approximately 1000 Quadski were produced in Michigan, USA, from 2012 to 2016, when production ended. The vehicle is no longer manufactured, either by Gibbs or under official license. An unlicensed copy of the Quadski has been attempted by the Chinese company 'Hison'. However, an actual Quadski is used in much of the marketing material, and there is no strong evidence that the imitation vehicle functions as an amphibian, as one user reported it is a poorly made copy of the original Gibbs, lacking many features, safety and quality.

Official Quadski parts & technical support are supplied by Gibbs Amphibians in New Zealand.
