Bikes wear out if you ride them daily. I also ride a cheap bike that doesn't have to work perfectly, but eventually everything breaks down. Even faster if you don't maintain them, and it will spread out to other parts if you don't replace the worn parts in time. Tires, brakes etc. just wear out in any case. You can then either replace parts or get a new beat up bike that at least rolls (and stops) for $15, but that's not always realistic. I'm tall and need a large bike, and these are not always easy to find used. tl;dr 50 is not a lot.
