Bryton Gardia R300L is a rearview bike radar and tail light designed to help cyclists ride with greater awareness, visibility, and confidence on the road.
By combining radar detection, smart light alerts, brake detection, and bike computer compatibility, Gardia R300L provides an added layer of protection for riders who share the road with vehicles.
Comprehensive Riding Safety Starts Here
Cyclists need more than visibility alone. While a traditional rear light helps drivers see the rider, Gardia R300L also helps riders stay aware of vehicles approaching from behind.
When paired with compatible bike computers or the Bryton Gardia app, Gardia R300L provides visual and audio alerts, helping cyclists better understand what is happening behind them while staying focused on the ride ahead.
Double Protection for Cyclists and Drivers
Gardia R300L is designed to support both rider awareness and driver visibility.
When vehicles approach from behind, the radar tail light sends alerts to the rider through a supported bike computer or app. At the same time, its smart light can adjust the warning pattern to help alert approaching drivers to the cyclist ahead.
This combination of rearview radar detection and active warning light behavior helps create a more aware riding environment for both cyclists and drivers.
Look Out Behind You
Ride with confidence with Bryton Gardia R300L.
The radar sensor detects vehicles approaching from behind up to 190 meters away. By working with compatible bike computers, Gardia R300L provides both visual and audio alerts, helping riders stay aware of approaching vehicles before they get too close.
Shining a Light on Potential Threats
Gardia R300L helps reduce unwanted surprises on the road.
When vehicles approach from behind, the device can assess the potential threat level based on relative speed and automatically adjust its warning light pattern. This helps notify vehicles coming from behind while giving the rider clearer awareness of rear traffic.
Brake Detection
Using a built-in G-sensor, Gardia R300L can detect when the rider is braking and activate a brake light to notify vehicles behind.
This feature helps improve visibility when slowing down, stopping, or braking suddenly, especially in traffic or changing road conditions.
Auto Light Change
When connected to compatible Bryton bike computers, Gardia R300L can use the bike computer’s built-in light sensor to adjust its light mode based on current lighting conditions.
In brighter conditions, the tail light can switch to day flash. In darker conditions, it can switch to night flash, helping riders maintain visibility across different riding environments.
ANT+ Light Network
With ANT+ integration, Gardia R300L can connect with compatible lights and bike computers to form a connected light network.
This allows riders to control compatible headlights and tail lights directly from the bike computer, including turning lights on or off and adjusting light modes.
Increase Your Visibility
Gardia R300L is designed to help cyclists stand out on the road.
Its daylight running light uses an interruptive flash pattern to increase daytime visibility, helping drivers notice the cyclist more easily during road rides.
Variable Light Modes
Gardia R300L includes multiple light modes for different riding conditions, including high solid, low solid, day flash, night flash, light off, and group ride mode.
When paired with a compatible bike computer, riders can adjust light modes directly from the screen for easier control during the ride.
Time Remaining on Battery
Instead of estimating battery life by percentage, riders can view the remaining battery time after pairing Gardia R300L with a compatible Bryton bike computer or the Bryton Gardia app.
This makes it easier to manage light settings before and during a ride, especially on longer routes.
Rechargeable Battery with USB-C Charging
Gardia R300L is built to support everyday rides, training sessions, and longer routes with reliable battery performance.
It also supports USB Type-C charging, making recharging more convenient. When the battery is low, the light can automatically dim to help conserve power.
Mount & Go
Gardia R300L features an all-in-one mounting system designed to make installation simple.
The included mount supports multiple seatpost types, including round, D-shaped, and aero seatposts, allowing riders to install the radar tail light securely and get ready to ride.
The Bryton Gardia App
The Bryton Gardia app helps riders unlock the full potential of Gardia R300L.
Through the app, riders can view the status of approaching vehicles, receive audio and vibration alerts, control the tail light, adjust preferences, and receive firmware updates.
Ride with More Awareness Behind You
Gardia R300L combines rearview radar detection, smart warning light behavior, brake detection, light mode control, app support, and bike computer compatibility in one compact device.
For road cyclists, solo riders, commuters, and anyone who shares the road with vehicles, Gardia R300L provides powerful backing for every ride.
