In the last 40 years can you remember an adult lead character choosing to ride a bike as a form of transportation in an American movie or tv series?
If a minor character has a bike and uses it for transportation - it's clear they would like a car but for whatever reason they don't have one. Another character might say to them "Why don't you have a car?" and their reply will be something like "Don't ask."
Last night I watched "Flashdance (1983)". Jennifer Beals plays an 18 year-old who lives on her own and she doesn't have a car. She uses a bike instead.
I can't figure out how/why I watched it in the 1970s. I was an elementary school and middle school then. And I was a dumb kid and I thought subtitled movies were "stupid". The only thing I can think of is that the local PBS station showed it and at that time I thought tv was the only true god so I guess I sat there and watched it and I read the subtitles. I don't remember a thing about it other than it seemed silly and "French".
Now I'm tempted to give the French one a try
