Earlier quoted context omitted.
I didn't say thousands actually (also specifically said it wasn't normal). It's just that I own a fairly mid-high end road bike (that I bought 10 years ago) that cost more than €1000. I used to ride a road bike that cost around €800 as my commuter bike until it got stolen. The quality at this price point is definitely worth it, with diminishing returns above it. I would strongly recommend upgrading to a road or town…
I’d honestly consider 800€ already enthusiast grade, but I’m interested. What does your 800€ bicycle have that mine doesn’t have? For reference, I’m currently using https://www.boc24.de/p/bocas-bari-trapez/217333/ (which I bought at 320€ on sale) with some changes (B&M 100 lux front light, seat post with suspension), and I don’t think I’d get any major improvements with other changes. Due to cycling in city traffic,…
Cheap wheels go out of true easily and before long are often too bent to be able to true by spoke adjustments. Cheap tires wear out fast and puncture easily. Cheap brakes wear out and go out of adjustment fast. Ditto cheap shift gear. I've broken pedals too, and I don't pedal all that aggressively. Really cheap stuff tends to be excessively heavy too, which can be a drag on uphills and when you need to carry it.
Yours looks like a perfectly fine commuter bike to me. I'm not familiar with the wheel or shift gear classes, but if it gets you where you need to go without wearing stuff out too fast, by all means no need to spend more.
