The Snow Scooter is used on compacted snow or ice: hiking trails, snowshoe or snowmobile trails, country roads, sidewalks, cross-country ski trails (skating), lakes, skating rinks, etc.
First of all, it is a well-known physical phenomenon. Think of the stools, to stand up the minimum is 3 legs … on 2 legs we fall. Also the 3-wheel scooteroffers a natural balance, as on the bike with small wheels.
