re: Motorized Snow Bicycle
Though 10 out of 10 for cool factor, for a pedal bike, I think it's a gimmick. More effort to ride than to just walk.
But for an Motored bike? Joe, you've made this a viable idea!
Imagine the children and parents alike, gawking in disbelief as you ride that thing UP the tobogganing hill! What a hoot to ride this thing down the street after a fresh snowfall!
And when the snow's not so fresh, swap the ski for a studded knobby tire.
Oh, someone please, build one!
