Motorcycles are fun, and so are jet skis, but do you really need one of each?

Gibbs Technologies doesn’t think so. It’s figured out how to combine them into a two-wheel amphibious vehicle it calls the Biski, which features a boat-like hull that lets you ride it on land or sea.

It uses a 2-cylinder motorcycle engine that’s connected to a water jet, and wheels retract and tuck into the hull when you ride it into the drink. Gibbs VP of Marketing Tom Berchulc says the 55 horsepower vehicle can hit 80 mph on land and 37 mph on water.

It unveiled the Biski at the AIMExpo in Orlando this week, alongside a larger, turbocharged 135 horsepower Triski model that features two wheels in front and one in the back, similar to a Polaris Slingshot.

Gibbs has been selling its Quadski amphibious vehicle for several years, but its four-wheel layout doesn’t allow it to be operated on public roads, since it doesn’t have the necessary safety equipment for a car. However, two- and three-wheel vehicles are considered motorcycles, which are easier to get certified for street use, and that’s a big part of the reason Gibbs developed the Biski and Triski.

They’re just concepts for now, and Gibbs doesn’t plan to sell them itself, but is looking to team up with an existing powersports manufacturer to put them in production. Berculic says the technology is nearly fully-developed, and either vehicle could be on sale within 12 to 18 months of a partner being found.
