Depending on how long it's been since you last bought a bicycle, there might be some degree of sticker shock when you start looking. Most decent road bikes are gonna start at a thousand dollars or so and go up—way up—in a hurry. Buying a $500 bike might seem like a good idea as far as an initial investment, but if you start riding regularly, you'll understand where the extra money goes. And while it's possible to upgrade a thousand dollar bike, a $500 bike is the type that gets sold on Craigslist for $250. Spend the extra money now to save some later.
