If I had that much money to buy a bike, and was still unsure of my commitment to cycling, I'd buy a nicely equipped used one for a fraction of that dollar amount and try that out for a while. In the meantime, you will discover what you need in a new bike, have time to research upgrades, and of course find out if cycling is for you. If you find that you would rather do something else, then you didn't lose so much money! Good luck on your decision!
