Being a sucker for amphibious vehicles, I find it really tough to let go of any amphibious vehicle announced! So, here is my next take on the amphibious vehicles list. Gibbs Technologies, known as the world's only High Speed Amphibian technology specialist, has recently introduced Quadski, a prototype of the world's first high-speed amphibian Quadbike/All Terrain Vehicle (ATV). The cool amphibious bike is capable of travelling up to 50 mph on land and water and makes the transition at the flick of a switch. Check-out the video here.
