Hello
Hello is there anything wrong with this that I should be aware of?
No, it is in great condition. It'd a solid bike and I am selling it at a solid price. 
$80 seems just a bit high to me for this. 
How much would you like to spend on this bike?
I was looking to pay more towards $40 
How about we meet in the middle. 60 dollars and it is yours. 
I can do that. 
Great. So do we have ourselves a deal? I can deliver it to you tomorrow.
Sounds great!
