I don’t know much about bikes. I bought my bike used off of someone years ago (blue one, first slide). Its fixed gear, 700c/38, 18.5”. It’s done me well- it’s sturdy, rides decently, has helped me get around the city.
I want to start biking more and I want gears. I found one in my price point that’s in good shape - only used a few times apparently (looks way better shape than others I’ve seen although not sure about that chain). It’s a Schwinn Circut hybrid, same size, though wheels are 700c/28.
Being that I don’t know too much, idk if this is a good upgrade or not? My current bike seems to have no branding on it- I have no clue what it is.

UPDATE: also now looking at a Giant, posted below
