CY-FI just unwrapped its latest wireless speaker system for your bike
. The CY-FI Bluetooth wireless sport speaker weighs just 4-ounces, supports hands-free and stereo Bluetooth profiles, and works for about 5.5-hours on battery when clipped to your bike or pretty much anything else. But by attaching it to a bicycle, Cy-Fi can call it a world's first Bluetooth sport speaker, which is nice. Unfortunately, the September 22nd launch with a $180 price tag is not.
