Safe-Tec is a small but mighty Helmet company base in Southern California offering new, intelligent Helmets for road and Mountain Bikers. Comparison test around the world showed the Safe-Tech Helmets as standouts when comparing sound, weight and safety ranking versus value. The Thor is Safe-Tecs dedicated mountain bike helmet that integrates speakers into the shell so you can listen to music while you ride without the use of obstructing headphones, you can also answer calls with the microphone cleverly hidden inside the chin strap where the control centre is also based. The Speakers work via a Bone Conduction system, which means even when there is lots of ambient noise, you will still hear well, very clever indeed! The Thor uses Bluetooth to pair your phone or device and has a Micro-USB charging port in the shell and is also IPX6 waterproof.
