I don't think that's right. Most of my bike rides are about 1-3 miles. When I commute to work it's about 6 miles and that's farther than most people bike here.
My commute would be almost six miles by bicycle. I'm not especially looking to replace the subway with a bike trip.
We cycled 8 miles to high school every day (so, 16 per day). Cycling 6 miles is not a lot, unless you have to stop every minute at a traffic light.
Up till 1.5 year ago (when I wasn't working remotely), I cycled 7 miles to work every single day (also through rain and snow). For good measure, I'd take an extra hilly route the way back twice a week for some extra exercise.
If you say so. It is for me. It's not only a long distance (google maps says 35 minutes, which I suspect is an underestimate), but also would be significantly inconvenient -- do I shower at work, and when I get home? What if I want to go somewhere after work -- leave the bike and come back for it?
I love the idea of biking, but I don't see it being useful for my commute.
Fundamentally there is no transportation solution to land use problems. If your destinations are inconveniently far apart, no bicycle, tram, bus, or train can fix that. The closest you can get to the convenience of a car without all the externalized social costs is an electric bicycle.
