The Loop 2 sleek, compact design provides dynamic visibility on your urban commutes. The convenient side button and easy installation strap were designed for busy lifestyles and fit all 22-32mm diameter bars. You’ll never have to worry, with the Loop 2’s long run times of 50 hours (flashing) and 30 hours (constant), you’ll always be seen. The long press on/off feature ensures your light will not inadvertently come on and run down the batteries while stored. Stay safe and be seen.
