Hello iasiia welcome to the forum. it looks like a late '70s early '80s low to mid range bike. I suspect it had drop bars at one time and was converted to "hybrid" style. as I am sure you know the front wheel is the wrong size. a proper front wheel and a little elbow grease you got a nice bike there
