certainly isn't for charity either. That mostly depends on the way you look at it.
It's been years since I've ridden a bike. Some lovely ladies and/or gents have made it possible for me and you to win one. If the prize is anything like the one shown, there is a nice place to put a few books.
In both of my towns the library isn't that far from where I stay. Plus, riding a bike is good for your body, which means it's good for your mind, and the environment. There, I made this post about books and the environment.
Can't fight the reasoning. Go ahead and win yourself a bike aka book chauffeur, that's environment friendly.
