Bike and it’s not close. I’ve loved being on my bike my whole life, ever since it was the easiest way to get to the public library as a youth. My hometown had a beloved, beautiful, and very extensive bike trail system, and in addition to my use of it for transit, my family would ride it together for fun every Sunday. At peak usage as an adult rider, my daily commute was ~27 miles. Currently it’s 9, but I do a lot of errands and shopping and recreational riding as well.
