Have not tried winter cycling yet, but I'm planning to at least continue to get my groceries by bike, run some errands, and do an occasional 20 mi ride this winter (snow removal permitting). I'm thinking of converting an old Raleigh Technium into my winter bike (700c wheels w/ studded snow tires for starters) but would it be wiser to convert an old mountain bike for this purpose? I guess I'm just wondering what qualities make an ideal winter bike. I'll be taking my other bikes off the road for the winter since the roads around here are salted and there is so much icy, slushy stuff on the roads all the time so I figured i'd start w/ something that was older and sort of worn to begin with but maybe this isn't the best perspective. any suggestions? I've got some major hills to contend w/ around here and if we get a lot of snow (last year we topped 100") then there won't be any shoulder and there will be patches of road w/ packed snow on them that I will have to cross just to get to town.
