A motorcycle, an ATV and a snowmobile each have very distinct functions. But what if you could combine them in one vehicle? Enter the Hyanide.

Hyanide Design

The Hyanide's design elements are unique. The tread comprises 77 plastic segments covered in the same kind of rubber used to make car tires. Kevlar, the same material used to make bulletproof vests, links the treads together. Unlike the heavy metal tread links on a bulldozer, the Hyanide's treads are relatively light and make it more maneuverable.

Steering the Hyanide is a bit unusual. A motorcycle rider steers by turning the front wheel, and a tank steers by moving just one of the two treads in relation to the other -- if the right tread moves while the left tread is still, the vehicle will turn left. But the Hyanide doesn't have a front wheel, and it only has one tread. When the driver turns the steering handle to the left, the front part of the tread angles to the left. Pushing back the left foot control will simultaneously turn the back segment of the tread as well, giving the Hyanide a very sharp turning radius. Meanwhile, the tread is constantly driving in the direction of the turn, so it always maintains maximum traction.

The driver implements the hand-and-foot steering system with two handles for his hands and two special footrests that accommodate custom-made shoes. A passenger can ride directly behind the driver, just like on a motorcycle.

The engine compartment of the Hyanide will accept engines currently on the market as well as future technologies such as engines powered by hydrogen fuel cells. The Hyanide's original design calls for a 60-hp 500cc liquid-cooled single-cylinder engine capable of pushing the approximately 600-pound machine an estimated top speed of 85 mph. This engine resembles existing ATV engines.
