Calling all multitasking cyclists. Your helmet can now be equipped with a Bluetooth communication and entertainment system. Yep, you heard us right. The Cargo BK-1, by Cardo Systems based in Pennsylvania, uses Bluetooth to stream audio to and from your phone and radio to communicate with other BK-1 devices. So you can talk on your phone, listen to your music and talk with other riders up to 500 yards away (assuming there aren’t any obstacles that would interfere). You’ll need to attach the gear to your helmet and do a little set-up before you get started, and of course you’ll want at least 2 of them. But now, your entire TrailblazerGirl peloton can keep talking while you’re riding along without missing a beat.
