Why the heck is it so hard to find a bike for a 5-foot-tall woman??? 😭

Guys, I need a new bike, but it’s literally impossible to find a bike for a 5-feet-tall 21-year-old teenage adult woman. All the bikes I find are literally for little children. No joke. I just want an everyday casual pink bike with a basket. Nothing fancy like those mountain bikes or whatever. I have always loved to ride a bike since I was a kid. It helps me go outside and stay active. I don’t know if my location is an issue because I live in America. And American girls, regardless of their race, are very tall. Now it feels literally impossible to continue this hobby because it seems like people of my stature are non-existent to their eyes. Help!!!
