#Person1#: Hi, there! Did you have any questions about our bikes?
#Person2#: Yeah. Do you work on bicycles in addition to selling them?
#Person1#: Oh, yes, we can handle any repairs you may need.
#Person2#: That's great, but what I need is not exactly a repair. My cousin gave me a road bike, but I'm not tall enough to ride it. Can you put smaller wheels on it?
#Person1#: We could do that, but I wouldn't recommend it, because you would have to use your legs more to go the same distance. You'd be better off buying a bike that's the right size for you.
#Person2#: I was afraid you'd say that. You see, my cousin's bike is a very expensive model. It's a really nice bike.
#Person1#: Have you considered trading the bike in? We do buy and sell used bikes, and I can give you a fair price for any trade-in.
#Person2#: Really? That would be great! How much can you give me for the bike?
#Person1#: If it's in good shape, probably at least 50% of its original value.
#Person2#: Terrific! If you're here tomorrow, I'll bring it in then.
#Person1#: OK.
#Person1# can help #Person2# who wants to put smaller wheels on the bike given by #Person2#'s cousin, but #Person1# recommends #Person2# to sell this bike and buy a suitable one.
