When I was a kid growing up in the Pacific Northwest I would say adults biked less but kids walked/biked more than today. I think adult biking is massively more popular and accepted today than in the 80s.
I remember begging my parents to let me bike to school because all the "cook kids" rode their BMX bikes to school and the bike racks were overflowing with kids who were biking to school. I remember being made fun of in the summer for taking the bus instead of riding my bike.
I don't remember seeing bike racks at any of the schools my sisters kids attended.
