I would advise and internal geared hub as the cassettes/freewheel can get encrusted with snow/ice and can easily quit shifting and and skip like crazy I've been using a Masi Sommerville 8spd and LOVE it!!!! I used to use an old Schwinn cruiser but my knees can't "take" it any more, if it's icey studs are a MUST!!!!!!!!!!! I've also gone from 26" wheels to 700c as they roll better, ride nicer and have a larger contact area.
