Hi, I'm interested in the road bike you have for sale. How old is it?
Hi its about 6 months old. Its in a good condition. I just got new tires installed. 
The price is a little high for me. I'm a college student, and I just need something to get around town. I have my eye on a few other bikes, and I'm looking to spend closer to $115.
Well, this bike is something rare and I am sure you can't get such a deal. Since your budget is around what you've mentioned, I can give it you for $190. That's about what I can do and I can accept installments if that makes it better for you.
