I came across an inspiring Australian blog today called Situp-Cycle (found it via Copenhagen Cycle Chic), which promotes bikes as a viable mode of transport...and even more importantly (or at least as important) bikes as being more fun if you are sitting in an upright position. It's a great site, and one which I encourage you to visit. Anyhow, below is a video from the site, aptly titled The Waltz of Bikes. It's a little over 7 minutes long and soothing (and inspiring) to watch. The video (or at least a shortened version of it) would make a great television advertisement for bikes (click here to read a recent post on that subject).
