Hyanide
The Hyanide is a hybrid motorbike vehicle designed and created by German designers Tilmann Schlootz and Oliver Keller. The motorbike is a combination of dirt bike-snowmobile-four-wheel vehicle concepts which was first showcased at the 2006 Michelin Challenge Design competition. It can move through deep mud, sand and snow terrains via a continuous track. Currently, only a prototype exists as a one-fifth scale model.
