It's a slightly odd way of looking at a bike - as to whether you get your money's worth.People rarely ask whether you get your moneys worth from a house, or a car, or a holiday, or a SLR camera.
It depends on lots of other things, particularly how much money people have. Cycling draws a broad range of people, with all sorts of incomes and motivations. There will be people on here who cannot afford a car and for whom £1000 seems well out of reach. There will be other people with £50,000 (+) cars who would pay £1000 for a bike for their children.
I earn reasonably well, but have responsibilities and outgoings also known as a family. I bought a £900 bike, apparently unused, for £543 on
Ebay. I reckon I've had my moneys worth. I don't use it to commute. I had an old MTB for that, but I retired it and now use an old steel bike. I've had my bike almost 2 years and have upgraded a few bits. I'd like a better/ new bike, but the problem is a £1000 bike isn't really going to be an upgrade. Because of cycle to work there seems to be a lot of bunching at the £1k point and I'm not convinced that I would really notice a difference until close to £2000. That seems like an awful lot of money to me, and would be something I would find hard to justify to myself, nevermind my family. However if I did buy one, it fitted and helped me achieve my cycling goals I would consider every single penny well spent.
I've posted on here before that despite riding a £500 bike the Etape Caledonia last year probably cost me £350-400. People find that quite astonishing, but neither me nor my family batted an eyelid at the cost, possibly because they were all involved and got a weekend away from it!
