Sign of low quality? Does one see the top of the seat stay, the circle. Any comments?

And has anyone ever seen these kinds of seat clusters on any brands? Thanks. Basically, it's a re-badged bike and that's why I'm curious. Otherwise, the bike doesn't seem that bad though of course, it would not be anything beyond entry-level I would think.

Thanks for any comments or ideas.

I'll add in, this bike has a cottered crank, it's not American made. It is British-made in this vein. It says so on the bike.
