Year round Boston, MA commuter, 2-4 trips per week. 17 miles one way, I live North of the city. Back roads by car takes about an hour. By bike, 20 minutes longer. On average. Don't miss sitting in my cage. I have 2 bikes just set up for winter commuting with studs. Several other year round options. Not for everyone, I find 20F is kind of my low limit, with 40F rain sub optimal. But those 30 -35 F winter days with snow and the roads are grid locked? Like 2 or 3x the ride home? Wicked awesome. They plow the bike paths here, regularly. Best are the bike paths for the last 6 or so miles heading into town, nice stuff. Thought about an e bike, just not yet. On longer daylight days in the summer, my pm commute goes to 20 miles with 8 miles of singletrack, winning.
