I got this bike when I was like 14, but that was a long time ago and now I’m 6 feet tall and 165 pounds. I still ride the bike constantly and really love it. The top tube is 20” and the bike feels maybe a little small. The cranks are also 185 mm which maybe is making the bike feel smaller because it puts my legs up by the bars (I got them for free so I didn’t really care). I really don’t care about the bike and don’t wanna spend any money. How much difference would it make to have a bike that’s my size?
