From the below video, it seems like the ktrak doesn't work nearly as well as a simple mountain bike. The guys with the ktrack are working a heck of a lot harder than the guy riding a normal mountain bike.

You can't mount skis beside your wheel and expect to be able to turn unless you do some sort of fancy linkages. (Bikes turn by leaning, skis would prevent you from leaning.)


I wouldn't expect the ktrak to work any better than typical 2.3 inch tires in deep snow (that is to say, not well at all.)

The only thing that's "good" for "deep" snow is a fat bike, and even that sucks once you get above 5-6" of snow or if the snow is particularly "mashed potato-y" or if the snow is crusty.

At about 2:00 in the video you see the guy with the ski on front going down a hill with 8+" of snow where as the guy with the front studded tire failed. Sure, that's all well and good but you'd NEVER be able to pedal through that. And the other 3 minutes of the video shows how much LESS control the guy with the ski has. It's a tradeoff.
