Bryton Gardia R300 / R300L Bike Rear Radar Review - feat. Brake Sensor + Standalone App + 190m Range

Bryton teased their Gardia rear radar back at Eurobike 2022 as a long awaited competitor against the Garmin Varia radar. Today, we finally have a production version for this review which not only competes with the Garmin Varia but also the relatively new Magicshine x Magene 508 radars. The Bryton Gardia R300L undercuts both radars with a competitive retail price of only $129.95 and a class-leading 190m detection range. The radar has a wide 220 degree field of view which allows you to spot cars around corners or in different lanes. Bryton has added a few modern features such as a brake sensor to detect when you’re slowing down and notify riders behind you as well as a USB-C charging port. The Gardia R300L can be paired with any GPS computer that supports radar displays or a stand-alone Bryton Gardia app to display oncoming vehicles and emit visual and audio notifications.

The Bryton Gardia R300L utilizes Bryton’s proprietary quarter-turn mount design. It’s essentially a Garmin mount but with thicker tabs. Although you can force it into a Garmin mount, we’ve found that it ends up bending the tabs over time which is why we don’t recommend it. Instead, Bryton includes a well designed seatpost mount that uses a standard rubber strap to attach to a seatpost. Right out of the box there are two additional rubber attachments: a flat rubber pad for d-shaped seatposts and a thicker pad for aero seatposts. Both attachments have cutouts that allow them to simply be inserted into the back of the mount. It’s an effective design that should work with nearly any bike setup and even has a built in angle offset to account for the seatpost angle. The only downside to the multi-piece approach is that you have to remember to keep track of the adapters.

Visually, the Bryton Gardia R300L doesn’t look significantly different from the Garmin Varia or Magicshine x Magene Seemee 508. The top third of the Gardia R300L is dedicated to the taillight while the bottom third is a flat surface for the radar. Dimensionally, the Gardia R300L is very close to other radars with a compact 40mm width, 97mm height and 20.9mm thickness. The big difference with the radar is that Bryton has utilized a square design, which in our opinion gives the Gardia R300L a more modern appearance. The surface of the radar has a matte plastic finish with rounded corners. Along the bottom edge you’ll find a horizontal cutout which hides the status LEDs to indicate battery status and Bluetooth connectivity. The taillight has a red lens with extended body for improved side visibility and a slight curved bottom edge which gives the radar a sleek look...
