I've seen some videos of that. Its a pretty silly invention if you ask me!

Too bad it does not work as well as two wheels in snow.
Their video only looks like the riders are going downhill. No demonstrations of level riding.

I've always pondered something that runs on conventional wheels but floats up in deep snow. Like maybe extending the fork legs and have skiis mounted at the ends on either side of the wheel. Or a snowboard-shaped thing with a notch in the middle for the bottom 1/8 of the tire to contact the ground through.

That bike probalby weighs less than my steel snow bike, even with the huge wheels and racks on it.
They still don't float over deep soft snow. But they handle much better. If the snow is deep it's actually less work to plow throught with a narrow tire. But the wide tire helps a lot of other things. If there is a hard crust the wide tire can keep you up on top longer. A very light bike and rider helps too.
