A:The $275 Cardo BK-1 Duo from Pittsburgh’s Cardo consists of a single unit that straps to your helmet, letting you talk via Bluetooth to other (similarly equipped) cyclists. You can also connect to your cell phone to listen to music, make and take calls, and listen to GPS directions. It doesn’t have a screen, however, and no speed and distance data from your cell.
There are also Bluetooth units for motorcycles, but they are heavier and don’t include the mounts for a bike. Adventurous users can also try the DIY approach to Bluetooth communication.
Overall, I was pleased with my first brush with the Hiod system, and will be sad when the review period ends for these devices. To test them, I took a serious 30-mile ride with a friend, and a mountain hike with my son. Both revealed the strengths and weaknesses of these new technologies. I’ll give you the lowdown on the good and bad after the jump.
