How much does a decent gravel bike cost in 2026?

What kind of terrain are you planning to mainly tackle? Anyway, it really depends on what you want to do, but honestly with 500€ you can manage pretty well if you're not too picky - you'll find brands like Decathlon or similar that offer good value for money. But if you want something lighter, with better components and that lasts longer, with 800€ you get a noticeable quality jump and you get a bike that'll go with you for years without problems. It depends on whether that's a cost you can comfortably afford, otherwise the 500-600€ range isn't bad either.
