Many years ago, I fixed up my wife's old touring bike for by sister-in-law to use while she was working as a river guide in Africa. Before she came home, she gave the bike away to someone who had been helpful to her. He eventually decided that having a bike was too extravagant, so he traded it for some cattle and was then in a position to get married, which he did.

I guess I'm saying even if the person you give the bike away to decides to turn it over for cash, it may still be of great benefit to him/her. However, I don't have any opinion on whether or not you should bring it home.
