This is an absolutely beautiful bike, I love it! How much are you looking for?
Could I interest you in this great bike!  I am looking for 45
While the bike is in good condition, it's used. Would you take 30? You can even keep the training wheels.
Hmm Its gently used. Could you go up to like 32.
Deal, but only because you were so kind!
Do you want too know anything else about the bike? I try to be kind!
No thank you, let's just make the deal!
Sounds like a plan to me! you like the color?
