There isn't a thread for the ski but if you want to see a long thread for the electric part of it -

I got a set of skis at goodwill for $5. Using one ski, a door hinge, and some hardware I mounted it up and hoped it didn't break. It ran strong the first outing hopefully it lasts the winter. I will get nervous when heavier passengers ride, however.
It's mounted to the bike just by the bolt through the axle and a pipe clamp at the top. I want to add springs or bungee cords so the ski pivots the way I want it, although it didn't have any trouble on the first ride.
Chicks dig the e-bike
