GASBIKE SNOW BIKE CONVERSION KIT

Maybe the rear track would stay, but no the skid is just not happening, I would say 4 inch wide knobby tires would be just as good with slightly more predictable handling would be better.

He probably can't pedal fast enough up hill to stay upright
 
I think that with a 2 stroke with a jack-shaft setup for low gearing on a 7 speed cassette you would simply terrorize the country side.
I bet you could do 20+ mph in fairly deep snow with a 5 HP 2 stroke.(unless you have a 300 lb ass)
A 5" fat bike tire does not come close to the surface area of this thing providing lift on the snow.
You get that thing in the right gear with a 160 lb rider and it will be a 7' high rooster tail of snow coming out the back.

Your opinion, which is fine, I rode snowmobiles and bikes and motocross all in snowy conditions. It looks like an idea that is only for the most dedicated of riders. It would be easier to strap my bike to the back of an atv or snowcat.
 
ATV's and SnoCats are ok if you got nothing but money.
I live north of 52 and its snow here 6 months out of the year.
You seem to base your opinion on the notion you are only going to peddle the thing.
I base my opinion on "I do not intend to peddle" the thing at all.
There is a big difference.
The thing never took off because its tough to peddle.
I do not want or need to peddle it.
That is what they make motors for.
Nears as I can see it has around 70-75 sq. inches of track floatation.
A 5" fat bike has maybe 15" to 20" sq. inches floatation.
Anyone with a fat bike better be prepared to do a lot of grunt work to go through any amount of snow.
And I'm just talking about the rear wheel.
That is why quads are useless in in snow more than 1 foot deep even though the got really "fat tires".
I ought to know my first sled was a brand new 1969 SkiDoo Olympic 335

theres a vid on youtube of this guy using a motorized ktrak. its got a jackshaft setup on it too.
personally i planned on putting it on my skyhawk with my 12 hp reed engine and do a single speed 40 tooth sprocket on a disc biscuit setup. id also put a surly single speed cassette on it for the pedal side. had this picked out for winter but there wasnt enough snow this winter unfortunately lol

Old snowmobiles and 80cc quads are nothing but money pits.
That old $250 sled will cost you a $1000 before you got 200 miles on it.
You will be towing it home more than riding it.
