My other option was leaving my all-weather beater bike down at the station near work. I ended up not doing that just because I didn't want to have to haul it back and forth a couple times a year for maintenance. But yeah, valid solution for sure.

I went with the simplest possible design for mine: fixed gear, v breaks sealed bearing wheels. Was basically zero maintenance as I only ever used the brakes for emergencies and used foot power for planned stopping etc. had gater tires, worked fine in the snow in Boston round all year.
