RUNGU FAT-TRIKE

The new bike by Rungu is the first all fat-tire bullfrog trike.
The bike features three huge, soft tires allowing it to “float” over
snow and sand, in fact the company states that this system improves
floating over these surfaces by 50% compared to regular fat bikes. The
Trike is perfect for transporting surfboards across the sand or pulling
stuff across the snow, it can also reportedly climb up short flights of
steps with ease and overcome obstacles up to 6” tall at crawl speed. via watch the video

Two models are available, the Juggernaut: features fat 26 x 4.7-inch tires and is intended for sand and snow, and the Kilimanjaro:
features a rear fat tire and two skinnier 29 x 2.5-inch tires in the
front, and is intended for use on the road or hard-packed dirt.
