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 mean I use random esoteric words in normal speech, because my brain is broken and when I reach for a word the filter is just "does this match what I'm trying to say" and considerations like "is this is a normal word or something I've only ever seen written a single digit number of times and that I inferred the meaning of from context?", "is this the correct language?", or "did I just synthesize this word from roots just now?" get skipped over until I've already said it.
But you've not showing off.
