OP, you have lots of options. If you have a frame that is comfy for you, and if you have some tools, or live near a co-op bike-repair place, or you are willing to invest in tools, and components, you can learn a lot of fun stuff doing component-upgrading and re-building. You can have a blast doing this. None of my bikes is "stock". It's a blast to change components, and discover "This is goood." Or not so much. I can't think of buying a bike, even a really good bike, and not trying to make it work better, for me to like riding it more.

I have all kinds of bikes, steel, alu-alloy, carbon, they are all fun to modify, and PLAY WITH. Think of bikes as open-design toys. You can have fun changing things on your toys.

If you want some kindof super stock bike, no changes required, maybe you can find it. But after awhile, you'll realize, "It's good, but I think if I modified it, it would be better." Or "I need a completely new bike." But even if you decide on the latter, if you ride enough, you'll find you want to do some mods.
