Product Details

Moon Helix Sense 450 Lumen Rear Light

The Helix Sense 450 is arguably the brightest and most feature-packed rear light ever made. Its unique Sense mode includes a brake light that increases brightness when slowing down, brightness sensing that automatically switches between daytime flashing and night mode, and a parking mode that turns the light to standby when no motion is detected. Additionally, the Helix Sense 450 offers a group ride mode, ensuring visibility during group rides without dazzling fellow cyclists.
