Fatbikes don’t replace skiing- I can’t go to the hill after work. Fat bikes are the tool to stay on the trails for more accessible activity close to home. For most of the winter (and shoulder season) our trails are packed snow or packed snow, ice, and mud.
Studded Wrathchildren are perfect for here. I don’t need more float than I get from 26x4.6- if I need it I’d have more fun on skis. Studs are a game changer, though.
