I own an iPOD an love it when I am working out. I went to the iHOME website and they have this wonderful iPOD player that is made for bikes! It attaches to your bike like a water bottle cage. No headphones needed so it is safe for you to use. One great big speaker and it even has a remote control that attaches to your handle bars.

It's listed under the portible audio and it the Bike to Beach Speaker. Item #iH85B. LOVE IT!!!!!
