Rungu Electric Juggernaut Steering


Why two wheels up front? The two-wheels-in-front design adds stability at slow speeds (think deep snow, sand, and stairs).


Why are the wheels so close together? Rungu Trike designs provide the balance between speed and stability.  The distance between the two front wheels lets you bank into turns like a bicycle but with adequate stability to let you stop without having to take your feet off the pedals.


Rungu Trikes use patented technology to connect the handlebars to the steering linkage. The stem-and-linkage assembly uses modified Ackerman geometry to minimize wheel slip for both front wheels when steering through a turn.
