I have never seen people do this. All I've ever seen is that those who spend extravagantly on bikes and gear do so because they are literally professional athletes. For everyone else, the closest to what you're talking about is just basic advise to spend only a little bit more on an entry-level bike because the so-called "department store" bikes tend to be notorious for being cheaply made and poorly assembled, requiring repairs in a very short amount of time. But even those bikes are perfectly fine if you're okay with having to spend additional money in the near future to replace problematic components, and either hire someone to fix it or learn how to do your own repairs.
