the best radar on the market for the price

- Flo 25 September 2026

Top-quality product; the LEDs are very bright. It’s also easy to use with the Rider S810.

A sense of security when you can no longer hear traffic due to hearing loss.

- Christiaan 18 August 2026

The product looks good and reliable. It comes with everything you need to attach it to your seatpost or saddle in a variety of ways. So far, the radar detection has worked flawlessly. It detects cars from a long way off.

Pros & Cons

Easy to pair with an iPhone
Easy to use with my Bryton
Good hardware
It works!!!
Versatile mounting accessories

- Kevin 10 August 2026

For this price, it really is a top-notch rear light. It does what it’s supposed to do. And the radar is accurate too. It does give you a greater sense of safety having the radar on your bike

Pros & Cons

Brake light
Displays the cars clearly.
Easy to pair with Garmin
The price is good value for what you get
It didn’t show the motor last time
Otherwise, nothing to complain about at all

Recommended especially for older cyclists.

- J. 27 August 2023

No false negatives. From cyclists behind, it depends on speed, if difference speed is too low, no notification follows. Explained to older cyclists along the way that this is better than an SH sign on the back of the bike. After all, more electric cars, more often tyres that make less noise, more often low-noise asphalt, and as you get older your hearing deteriorates, this works better than a mirror.

Pros & Cons

light visible at long distance
low power consumption
reliable notifications
also gives notification of cars when driving on the fie
counting?
path next to the road. Perhaps a matter of counting

Excellent Radarlight fair priced

- Marvin 24 February 2023

Finally I got my hands on the Bryton Gardia R 300 Radarlight. The built quality seems to be good and so far I didn't notice any concerns about this with 500km testing. The functionality and set up via app or bike computer is fairly simple and done within 1-3 minutes. There must be said, that some parts of the appeal are not or if not well translated from Chinese (i guess). I mainly use the low light mode and love that it's only blinking when a car is about to approach. The radar is really reliable and I only noticed one false positive (a car shown but none approaching) once and no false negatives (a car not being recognized) which is way more important. Multiple cars are recognized smoothly and trucks will be shown as multiple cars together (2-3 depending on the trucks size). Loading with the provided cable is easy and doesn't take to long. I can just recommend this beauty. Just to be said with those radars it's the same like with electronic shifting - you don't really need them to enjoy a ride out, but once you used one you don't want to miss it.
