I saw this video on the vintagesleds.com website a few days ago. There of course was some comparison to the old Bolens Diablo Rouge vintage snowmobiles and their predecessors the Hus Ski. Those two sleds had tracks up front that pulled a sled that the driver sat on. I had one that I restored a few years ago that was a blast to ride.
It will be interesting to see if this electric utility snowmobile/atv will catch on. But I like the idea.
