The Cardo Systems BK-1 is a practical solution for spandex-sporting cyclists who don't have anywhere to stash their electronic devices, but still want to stay connected when they're riding.
Compatible with any brand, size or style of bike helmet, the device lets riders communicate with other cyclists, listen to music, or connect to their mobile phone without having to remove their hands from the handlebars.
Along with the contacts in one's cell phone, the device allows users to connect to other cyclists within 1,640 feet. This feature can be useful for starting conversations with other riders or as a useful emergency tool to warn riders if there is rough terrain ahead or to call for help if there has been an accident.
The Cardo Systems BK-1 is waterproof and features automatic volume control by taking into account the rider's speed and the amount of background noise. These features ensure that the rider can control their devices without worrying about losing control on the road.
