Open the box for the Cy-Fi and you'll be surprised at what's missing. There's no CD with an online manual or synchronization software. There's no USB chord or instructions in seven languages. There's only a wall charger, two mounting clips, the transmitter and the speaker itself. Stick the transmitter into the bottom of your iPod press play and voilá; anyone with 20 yards is listening to your playlist. Even the mounting clip is simple and adjustable to various handlebars. The clip remains on the bike for future usage while the speaker clips easily on and off. The transmitter only adds an inch of length and the iPod can be stuffed in your pocket or, in my case, in the front basket of the attractive blond riding alongside on her own beach cruiser. The speaker itself has buttons for adjusting the volume, play/pause and skipping tracks. Our lone complaint was the buttons were a bit tough to push while controlling a bike and weaving through tourists.
