Cardo BK-1 Communication System


The Cardo BK-1 is a helmet-mounted communication system that allows you to talk easily to a ride partner via Bluetooth

The Cardo offers simultaneous conversations via intercom between up to three cyclists, mobile phone connectivity, in-the-ear instructions from GPS devices and MP3 stereo music streaming from compatible devices. Whether you cycle alone or in a group, the Cardo BK-1 will give your favourite outdoor experience a whole new dimension.”

Installation and setup of the BK-1 system is simple and straightforward thanks to detailed instructions. The transmitter fits most any helmet with supplied Velcro straps, and the actual headset mounts to the inside of your helmet with an adhesive strip. A wire connects the two and sits unobtrusively at the back. Once you familiarize yourself with the transmitter’s five buttons, channel operation is a snap. The earpiece is comfortable and unobtrusive, as is the microphone.

The BK-1 unit is waterproof, and the Li-polymer battery provides up to seven hours of talk time. It takes three hours to recharge fully from empty.
