Watch this instructional video from the Transit Authority of River City (that’s Louisville, Kentucky), and trust me, you won’t be able to dislodge the chorus from your head for days. I never thought of bus-mounted bike racks as the stuff of infectious music videos, but I was wrong — egregiously wrong.

Active Living by Design has the full story on this stroke of marketing genius, produced after a survey revealed that many young women in Louisville wanted to use the bike racks but didn’t know how. A follow-up vid on bus etiquette is in the works.

Any chance this starts some sort of viral trend that extends all the way to New York City Transit’s PSAs?
