Garmin Varia RTL515 Rearview Cycling Radar, Built in Tail Light, Compatible with Edge Bike Computer, Multiple Display options, Visual and Audible alerts, Daylight visibility up to 1 mile

I cycle a lot, all year, in all weathers. Primarily road cycling. This rear light and radar is expensive. But. Its a good light with good range and handles spray and heavy rain well..no issues with battery life and I'm told that it's pretty bright. It links to my Garmin Edge 530 easily for the radar and for any necessary software updates. Comes with variety of attachments to suit your seat post. The radar, which is the main reason for my purchase activates pretty accurately and in my view is a great safety addition especially at night or bad weather. Its radar function notifies vehicle proximity on my Garmin Edge 530 by flashing orange and reporting the cars location as large white dots approaching you on the right of the screen. The first beep and flash to indicate a car is approaching from the rear occur at about 60-75 meters away. It also indicates how many cars there are each with their own dot closing in on you. In my view it's pretty accurate most of the time. The Edge display functionality is not affected when notifying you. Display screen borders change colour when there is a car directly behind you roughly 2 to 3 meters away. It does not replace physically checking before making a move or turn. But it helps as an additional safety tool to improve your road awareness and a prompt to check before moving. Could do with a small elastic lanyard to larks-foot around the seat post incase it's mountings we're to loosening come off, in the same way as the Edge 530 has. Would I recommend....Yes. Strongly. I don't cycle without it day or night.But its not cheap!

To be honest, this device actually works better than i'd expected. It gives a clear audible and visible indication of approaching vehicles (cars/bikes and lorries). The sides of the screen on the Garmin head unit light up amber or red depending upon the approaching speed. Once a vehicle (or multiples, it shows a dot on the right hand side for each vehicle) have passed, the screen sides go green for a few seconds to show it's clear. This unit has allowed me to know that vehicles are approaching before i even hear them. Of course you can't tell how close someone is passing but it's a massive help overall. It's actually useful to just know when there is nothing behind to, without having to keep looking back. It hooks up to the head unit with very little effort and just works. Brilliant piece of tech !!!!

This is an excellent product to increase your safety whilst out on the road. The device gives plenty of warning of approaching traffic and the display on my garmin computer shows the distance the vehicle is behind which is a great feature. Battery life is good and lasts a couple of rides for me which is about 7 hours approx.

The unit itself is a good size, and locks securely into the Garmin mounting mechanism. The way the mount fixes to the bike is just not fit for purpose, I tried it on my first ride, and whilst initially is was giving very accurate results, it started to miss cars coming up behind me. When I stopped, the mount had moved around the seat post to the extent that it was now pointing more towards the kerb than the road. It is held in place with a rubber band, the small one was too tight, and the large one was slightly too big - what a farce for something costing so much. I have had to purchase an additional fixing (£11) to fix it to the saddle so that it cannot move, and on my second ride with this new fixing it was 100% accurate. This reminds me of the rubber band mounts you used to get with lower range Garmin Edge computers, with my latest device (Edge 1030 Plus) coming with a proper mount. Come on Garmin, the mount supplied with this is just not fit for purpose, and whilst a generic seat mount to fix this was only £11, this device should be capable of being securely fixed out of the box. The device itself is absolutely fab and gets 5 stars from me, when mounted correctly, but the Garmin mount gets 0 stars from me, totally useless. I seldom write reviews, but the poor mount supplied by Garmin with this has forced me to do so.

Il Garmin Varia RTL515 è un accessorio indispensabile per chi pedala spesso su strada. Il radar posteriore rileva i veicoli in avvicinamento con grande precisione, aumentando la sicurezza in ogni uscita. La luce LED è potente e ben visibile anche in pieno giorno, con diverse modalità adattabili alle condizioni. Compatto, affidabile e semplice da usare: un vero alleato per pedalare con tranquillità. Consiglio!

Perfecto el producto,. Envío rápido. El radar y la luz totalmente recomendable para salidas en bici de carretera. Con el Garmin 1040 funciona prefecto.

Le Garmin RTL515 combine lumière arrière puissante et radar pour prévenir des véhicules en approche. C'est fantastique ! Je ne me vois plus aujourd'hui rouler sans le radar fixé à ma tige de selle ! Quelle sécurité d'être prévenu des voitures, motos, camions en approche. Combiné à un compteur (même le basic Garmin Edge 530), l'affichage est clair sur l'écran du compteur et cela fonctionne même avec certaines montres Garmin (je peux aussi avoir l'alerte sur ma Forerunner 945 qui a pourtant 4 ans). La précision est excellente, il y a très très peu de faux positifs (c'est généralement un cycliste qui me double un peu "trop vite" qui est détecté). Fonctionnement : lumière fixe quand pas de danger, elle se met à clignoter vigoureusement à l'approche d'un ou plusieurs véhicules. Très efficace, même en journée avec le soleil ! Absolument rien à redire, l'investissement est important mais le prix Amazon est meilleur que tous les autres sites internet, même à l'étranger. L'autonomie est très bonne. Donné pour 16h de lumière non stop. L'application mobile dédiée donne le niveau de batterie, ainsi que le compteur Edge ("batterie radar faible") donc aucun souci à se faire pour faire des charges presque complètes et prendre soin de la batterie interne. A compléter avec une protection en silicone type Tusita (10€ sur Amazon) pour protéger le radar.

Spokój ducha, jakie daje to urządzenie jest wręcz nieocenione - niezależnie, czy jedziemy drogą, gdzie wyprzedzają nas auta, czy ścieżkami/w parkach, gdzie mogą nas wyprzedzać rowerzyści 🚴‍♂️. Zasięg wykrywania jest na tyle duży, że jesteśmy powiadamiani jeszcze zanim zdążymy usłyszeć nadjeżdżający samochód - nie mówiąc o tym, że czasem przecież w ogóle ich nie słychać (przez wiatr lub np. w przypadku elektryków). To zapewnienie, jakie daje urządzenie z jednej strony pozwala nam jechać bardziej środkiem pasa, unikając studzienek czy większych ubytków w jezdni, a z drugiej pozwala z odpowiednim wyprzedzeniem zrobić miejsce pojazdom. Do działania lampki również nie mam zastrzeżeń - włącza się po rozpoczęciu treningu, gaśnie po jego zakończeniu, mamy kilka trybów do wyboru. Jedyny minus to ładowanie przez stare micro-USB. Jedyna sytuacja, gdy radar może nie informować o pojeździe z tyłu (a raczej błędnie poinformować, że go już nie ma) jest sytuacja, gdy ten zrówna się z nami i będzie podążać z tą samą prędkością np. czekając na możliwość wyprzedzenia - wynika to wprost z zasady działania urządzenia, ale warto mieć to na uwadze :)

Good battery life and so worth the money. I feel so much safer being able to react to traffic, works well on quieter narrow country roads as I can ride in the middle of the road until Rader detects a car then I can move over
