CETUS-1700 Underneath Mounted Bike Light

DESIGN INSPIRED BY THE WHALE

Inspired by the 'black' and 'white' of whales  it showcases the purest contrast aesthetics in nature.

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 Cutoff 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

WIRELESS REMOTE CONTROL
ONE-KEY SWITCHING

Easily switch between 6 light brightness levels without taking your hands off the handlebars, making cycling safer

INTELLIGENT START-STOP: SEAMLESS OPERATION

Reinventing the traditional manual switch mode, it intelligently detects  riding status—automatically entering sleep mode after 2 minutes of  stationary parking, and instantly lighting up when vibration from  pushing the bike is detected.

FRONT LIGHT SPECIALLY DESIGNED 
FOR UNDER MOUNTING

The sleek and quick-release overhead mounting system allows installation/dismantling in 1 second. The patented buckle design ensures stability and firmness, easily handling bumpy gravel roads.
