On the one hand, one of the simple pleasures of a bike ride is how quiet it is. It's so silent that I frequently startle wildlife. On the other hand, sometimes only tunes will keep your legs pumping, and using earbuds or headphones on a bicycle is wicked dangerous. There is also a sense in which riding down the street playing you music is like walking down the street with a boombox, or driving around in a Camaro playing rap that shakes windows. We oughtn't be public nuisances, after all, and imposing your personal cacophony on the rest of the world is worse than being a cell phone pest. One the other hand, our music is pretty good, and the Cy·i is pretty cool. It's a wireless speaker that mounts on your handlebars, which means that your iPod can go in your pocket or backpack. Even cooler is the fact that you can broadcast to other Cy·fi users in your peloton. Something about that appeals to the control freak in me. Recommended for cyclists who call "shotgun" because they want to control the radio.
