Bicycle commuters often easily ride 400 miles / 640 km in a short time. I commute about 3000 kilometers a year. I live in Norway and often skip a couple of
the harshest winter months, but ride the rest of the year. I have bicycled about 21000 kilometers with my current cummute bike:)
Maintenance adds a bit to the carbon emissions, but a chain, casette, and other small parts is peanuts compared to cars anyway.
