Hello, I'm interested in your bike, can you tell me more about it? 
Hi! It's brand new with a new motor. I was hoping for around 400
Would you happen to know how fast the motor can make it go? 
I've been able to get around 25-30 on it
Okay, how does $350 sound for it? 
Hmm, if you can pick it up in the next couple days that's fine
