A powerful ally for your safety.

Ride with complete confidence with the Bryton GARDIA R300L rearview radar. This rearview radar with taillight offers double protection to support you during your rides. When vehicles approach from behind, in addition to notifications on the bike computer and GARDIA app, the Bryton GARDIA R300L will automatically change its lighting mode to warn oncoming vehicles.

A look behind you
Ride safely with Bryton Gardia R300L. The Gardia R300L radar sensor detects vehicles approaching from behind up to 190 meters away. When connected to compatible cycling computers, Gardia R300L provides both visual and audible alerts to warn you of oncoming vehicles.

Detect potential dangers
The Bryton GARDIA R300L Rearview Radar helps you avoid nasty surprises while cycling. When vehicles approach from behind, the GARDIA R300L will automatically assign a threat level based on speed, then activate a warning light to alert oncoming traffic.

Automatic light change
When connected to a compatible Bryton cycling computer, the GARDIA R300L will use the device's built-in light sensor to adjust the lighting mode based on current light conditions. If sufficient light is detected, the taillight will switch to day flash mode to conserve battery life, or automatically switch to night flash mode during nighttime riding.

Brake detection
Using a built-in g-sensor, Bryton GARDIA Radar Rearview Light detects braking and warns vehicles behind you with a brighter light, reducing the chance of collisions while slowing down or in case of emergency braking.

ANT+ connection
Using ANT+ connectivity and an ANT+-enabled bike computer, you can connect the GARDIA R300L and a compatible front light directly to the bike computer to form a network that allows you to manage all your lights from the display – including turning them on/off and adjusting lighting modes.

Increase your visibility
The Bryton GARDIA R300L Rearview Radar with Taillight is designed to highlight the position of cyclists and help oncoming vehicles spot them. During the day, a dedicated flash mode increases visibility up to 1.6 km.

Various lighting modes
The Bryton GARDIA R300L provides multiple lighting modes to support your ride and keep you visible in any condition, including high-intensity steady, low-intensity steady, day flash, night flash, and group mode. With a compatible cycling computer, you can also adjust lighting modes directly from your screen.

Powerful and rechargeable battery
With a whopping 17 hours of battery life in daytime flash mode and up to 12 hours in steady mode on a single charge, the powerful GARDIA R300L rearview radar and taillight can support you no matter how far your adventure takes you. To further extend battery life, the light intensity is automatically dimmed when the battery is low. USB-C charging also makes charging faster and more convenient than ever!
