Bryton GARDIA R300L Cycling/Bike Radar with Tail Light, Visual and Audible Alerts for Vehicles up to 207 Yards Away, IPX7 Waterproof, Viewing Angle 220°, Support APP Display

Delivered quickly. Priced better (less than half) than comparable Garmin unit. I like the quarter turn mount and it feels solid. It paired with my Bryton S800 head unit seamlessly and it displays a little graph that is intuitive and helpful at a quick glance. The audible beeps are also helpful and easy to decipher. It has been very accurate with detecting vehicles in daylight, dusk and night rides. Never had it 'miss' a vehicle yet but have had a few 'false positive' detections that usually resolve quickly. Gives great confidence of approaching vehicles. It shows how many vehicles and their relative distance to me and each other. Closing speed and 'all clear' indicated by differing color of graph. Doesn't seem to false detect cyclists as vehicles. It did take me a few rides to notice that vehicles that are moving at the same speed as me won't necessarily be detected or continue to be tracked if they initially are detected, those may 'clear' with a green indication and beep. They do 're-acquire' if they begin to close distance though, which all makes sense but took me getting used to.Riding with buddies that have the very similar Garmin Varia, the functionality seems nearly identical. They also get occasional false positives though not necessarily at the same moments. The light is bright and has several modes. Battery life seems to be as advertised which is very good and MUCH better than the Garmin my buddies use. It does shorten the battery life of my head unit slightly when in use, maybe 10% or so. My S800 has an almost 25-hour batt life with my particular paired devices (HR monitor, speed/cadence, power meter) so I barely notice to be fair. If I unpair the radar, I assume this would not happen but have not tried that as I'm looking for more than just a taillight obviously.

I was going to buy my girlfriend a Garmin Varia for her birthday, but I saw that Trek had advertised a new RADAR which claimed to have better detection than the Varia, so naturally I wanted to research that. I found an extraordinarily thorough review by a guy down under comparing the Varia, the Trek, the Bryton Garda, and one other model that performed poorly. Turns out the Trek didn't live up to the claims, rarely alerted before the Garmin, and had a narrow field of view. The Bryton however seemed to match the Garmin note for note. Further, it has USB-C charging (I hate micro-usb) and some additional features that the Garmin doesn't have. I went in looking at the Trek, and ended up buying this light for her instead.In practice with us riding side by side, they alert at pretty much the same time and have the same stellar accuracy. If I lost my Varia, I'd replace it with this model (the mount is better than the Garmin mount as well).

Riding with Garmin Varia or Bryton Gardia is game changer due to awareness of surroundings that it provides. One feels safer on the road as you are aware of traffic behind you. I used both with Garmin Edge 830.Similar to Varia1. Integration with Garmin - automatically connects2. Visual of traffic approaching is very comparable to Varia3. Needs space underneath the post; you are mostly likely to lose space for saddle bag.Advantages of Bryton Gardia1. Affordability: This is 60% of the cost of a Varia which is not small change2. Mounting: The band and holder is more robust. It is easier to strech around the post3. Aesthetics: I think the product looks quite attractive with rectangular design and light is bigger.Disadvantages of Bryton Garia1. Car waiting behind you: When a car is behind you and it is waiting behind you, the car disappears from the radar as if there is no car behind you. It seems radar is unable to see cars if the distance is being maintained between you and the car.2. False Alert: At times, car gets stuck in your visual in Garmin. This happens about a couple of times on a 90 min ride. Even as car has passed you and there is nothing behind you it will show that there is a car. You know it is a false alert as the car is almost bouncing on the Garmin screen - going forward and going backward3. I have used it only for 4-5 rides and already had to charge is once. I have not experienced the 17 hr battery life that is on the description.4. In a 90 min ride, you will see message of 'Radar has been disconnected' on the Garmin. It gets connected within 5-15 seconds...but during that time you are on your own.5. You need to download the phone app primarily to update software. You can use it while riding as well but with Garmin bike computer, you do not need to use it.I have to test for a few more rides and have enjoyed the awareness that this brings while riding.Update Feb 4th, 2024Bryton's latest software update seems to have corrected the first two disadvantages. No more false alerts and if a car stalls you can still see it. Fantastic product.

I have found this to be very reliable, and while I can't really judge whether it notifies you in the claimed distance, I can say that it gives you plenty of warning of approaching cars. It is also very adept at noting when there are multiple vehicles behind you. I have it paired with a Bryton Rider s800 and it connected quickly and easily and I like how it shows in red instead of yellow on the screen when cars are approaching quickly. The battery has a good long life; I haven't tracked the hours exactly but I can go on a few long rides between charges. This is my first radar and for sure I will never ride without one again, it really is a great safety device

Se sincroniza bien con Garmin edge 1040, pero el radar en ocasiones se desconecta y tiene el problema que detecta una bici como si fuera un automóvil o simplemente aparece el indicador de vehículo en el radar en una carretera solitaria, es decir, sin vehículo.

Producto de buena calidad 👌 ✅️

I wasn't sure what to expect from a radar rear light. The LED output is maybe not in the same league as some super bright rear lights but is more than good enough to be seen.The radar is gge reason to buy it and it works really well, detecting well before yiu would ever hear a car. Will show multiple cars on thr side of your ANT+ compatible computer. As others have said , it can go "clear" if a car moves right up on you and sit on your tail at the same speed, but by that time you are well aware of it being there.I think it is a great addition to any road cyclists bike,really happy I bought it.It was available at a great price during the summer.

Ho già il Garmin 515 Bryton costa meno e non ha niente da invidiare a Garmin

I bought this as I like the added awareness of being able to know if there's something coming up from behind in advance. It's still important to check over your shoulder though.Vehicles are detected according to their closing speed so if there is a car behind you and it's travelling close to your speed it drops off the sensor. It's important to appreciate this fact.The light itself was easy to set up. It comes with the elasticated fittings that seem commonplace on bike lights these days - but once in place it seemed firm. The light unclips from the mount easily with a quarter turn.There is an iPhone app which in my opinion gives a much clearer impression of what is coming than the Garmin widget at a glance, but it works well with both devices. Setup was painless, but the Garmin seems to have trouble with Ant+ devices periodically, not just this one, so occasionally the sensor would not be picked up without the Garmin being shut down completely.The associated app also lets you switch the light mode remotely, although I felt there should be an additional on off toggle in the app rather than having to tap the light icon and then off.The price is around half the price of the Garmin Varia - certainly good value for money.
