The perfect snow-bike

Why two wheels in front? Snow-bikes don’t need them…

The two front wheels make Rungu easy to control on soft sand, mud, ice and snow. It’s hard to control any two-wheeler (like “snow-bikes”) on slick or soft surfaces regardless how “fat” the tires are. When you turn a snow-bike, all the turning force on the front tire is directed through a narrow strip of tread on the front tire that follows the turning circle. That narrow strip of tread on the inside of the turning circle of a snow-bike needs a surface it can grip, or it skids.  If you don’t straighten out the snow-bike in an instant, the skid can result in a “low-side” or “washout,” or worse, a “high-side” or “over the handlebars” crash.

The dual-front-wheel design provides control on slick or soft surfaces. Rungu uses a form of Ackerman Steering so that the center of the turning circle for all three wheels is the same. When you turn a Rungu, you always have one tire on the inside of the turning circle.  You use the whole surface of that tire for traction in the turn.  Rungu “digs in” instead of “washing out” like a snow-bike.
