SIGMA BUSTER 900 LINK – powerful light. Intelligent connectivity.

Up to 900 lumens, a range of up to 180 m and intelligent control of your bicycle lighting.

The SIGMA BUSTER 900 LINK is a high-performance light with a helmet mount for cyclists who expect powerful illumination, convenient operation and modern features. The wide, even beam helps you see the road and obstacles on dark routes, while the range of up to 180 metres supports orientation when riding after dark.

Key benefits

Up to 900 lumens – effective illumination of the road and surroundings.
Range of up to 180 metres – better visibility on dark paths.
5 lighting modes – adjust the light to the conditions and your riding style.
LINK connectivity – wireless interaction with compatible SIGMA rear lights.
SIGMA RIDE app – light configuration, battery monitoring and software updates.
LIGHT GUIDE – improved side visibility.
USB-C – convenient charging, including during operation.
IPX4 protection – resistance to water splashes.

Connect the light to compatible rear lighting such as BLAZE LINK, HIRO LINK or NYTE LINK. With the LINK function, the front and rear lights can form a shared system that you can control conveniently.

The light is also compatible with the RECO compatible rear radar. Information about approaching vehicles can be displayed on a compatible cycling computer or in the SIGMA RIDE app.

Control from your smartphone or handlebar

With the SIGMA RIDE app, you can change the lighting mode, check the battery charge level, give the device a custom name and update the software.

With the optional REMOTE ONE remote control, you can change the lighting mode directly from the handlebar. The memory function stores the last setting used, while the accidental activation lock requires the power button to be pressed twice.

Visibility from every direction

The integrated LIGHT GUIDE improves the light’s visibility from the sides, which is particularly useful when crossing intersections and riding in urban traffic.

Easy mounting and USB-C charging

The included mount with a Quick Release mechanism allows you to quickly install the light on the handlebar and remove it without having to adjust it again. Optional mounting solutions such as AERO SILICONE BRACKET and AERO BUTLER GPS are also available for aerodynamic handlebars.

Charging via USB-C takes approximately 3.5 hours. The light can also be charged while in operation, while IPX4 protection safeguards it against water splashes.
