The snow has arrived in northern Indiana, and my daily commute has gotten difficult. For some of my commute, I travel the sidewalks. Unfortunately, the sidewalks have frozen foot prints that make traveling them difficult. Has anyone rode over these conditions without problems? I'm thinking a single speed fat bike might do the trick. I would prefer a plus bike for the lighter weight, but it seams like many people say it isn't fat enough. Riding in the street safely isn't a option. Also, have any of you had to get off and walk because you couldn't ride thru the lumpy frozen snow? What are your thoughts?
