As we know, listening to music while you’re biking is great fun, but dangerous because it isolates you from the rest of the world, including traffic. In many places it’s illegal to listen to music on a bike.
Tunebug have come up with something pretty darn cool. They make sound surface products that turn surfaces into speakers, and their Shake system uses this sound surface coupling technology to turn the bike helmet itself into a speaker, so you don’t have to wear headphones or earbuds. This way, you can listen to music and not miss what is going on around you, like the squealing of brakes of a car about to run into you.
