Them and Their Bikes

I am not normally a fan of rap music (with the possible exception of early Beastie Boys and Grandmaster Flash) but this is pretty good...and it has a positive message (something, it seems, which is often difficult to find these days). It's an ameture video which won a contest for 1MinuteToSaveTheWorld; it's worth watching, and of course it's only slightly more than a minute in duration.
