The Power of Two Beams, One Command
-
Low Beam (The Urban Diplomat): With a clean, anti-glare cut-off line inspired, this mode casts a wide, even beam that illuminates the road in front of you without blinding oncoming drivers or pedestrians. It's powerful, yet respectful—the ultimate tool for safe and civilized city riding.
-
High Beam (The Trail Dominator): When the city lights fade away, a single click unleashes a torrent of 1700 lumens in a powerful, far-reaching high beam. See every corner, every obstacle, every detail on the trail ahead, and ride with the confidence of total visibility.
