It is a given that riding in the snow is neither easy nor fast. 8-10 mph is what I expect. When the roads are clear I'll take the Nishiki out and maybe go 15. The choice is between riding outside at all vs. spending the entire winter as a shut-in on the trainer. And I have to tell you, when you show up for lunch across town in December on 2 wheels you get to state self-righteously that everyone else is a sissy.
I have a couple of friends with Pugsleys. Those are great -- they ride up over everything. I'm not ready to drop that kind of $$! I think both Salsa and Surly are owned by QBP.
