AERODYNAMIC DESIGN

The R&D team conducted repeated experiments and simulated wind resistance tests, adjusting the shape repeatedly, and finally achieved the optimal aerodynamic design. With a drag coefficient of only 0.35CD, it reduces wind resistance by more than half compared to traditional bike lights (0.8CD) — the effect is equivalent to reducing 500g of weight during cycling.

Optical Cut-off Line for Low Beam & Clear Vision in High Beam

Professional-grade high and low beam design ensures clear visibility in both lit streets and unlit roads, allowing seamless switching between urban and off-road cycling.

Ultra-Wide Light Effect

No blind spots when cornering at high speed.

The light's visual range width reaches up to 30 meters, ensuring a daylight-clear vision for night cycling.

1700 Lumens with Six Modes

Different modes meet the needs of various road conditions
