Skis instead of the front wheels, tracked bogies instead of the rear wheels and removing the differential -> some fun in the deep snow. To be honest, I regret not having any motorized 42069 version at hand.

 

I'm dissapointed - why it is so slow?

Because I geared it down and used sprockets that are much smaller than 42124's original wheels. I expected that a lot of torque would be required, and with fresh, deep snow this appears to be true. On an older, hard packed snow you could probably drive the regular 42124 at normal speed, but then it wouldn't be much different from driving on solid ground.

Wouldn’t the original tyres work well on snow because of the tread?

When I made a snowmobile, I found it helped to add small fins (i.e. 30413) to the bottom of the skis to improve steering authority. I also added camber, like on a real snowmobile, but I'm not sure how much of an effect it had on the steering.

Then why not to use buggy motor with buwizz? ;)

Probably not on a snow this deep and soft.

I don't think one buggy motor would perform that differently from two C+ L motors, plus I would need to rework most of the buggy to fit that motor in there somehow. As you can see below, L motors are a pretty good option for driving on snow:
