Garmin Varia RTL510 Bike Radar Tail Light-Black

I paired this with a Wahoo Elemnt Bolt. It works almost flawlessly. The light is bright and effective with pretty good battery life. The radar is a game changer. I've only done a few hundred miles on country lanes with the radar unit but it has never failed to warn me of cars approaching. It even shows me if there is more than one car approaching and gives an indication if the closing speed is high or low. Sometimes if a car approaches and then slows down to match your speed, the radar seems to think it has disappeared but it soon picks it up again when the vehicle speed increases to overtake. I used it on a group ride and it occasionally picked up one of the other bikes if they were moving quickly past but otherwise it picked up approaching cars long before anyone in the group heard them. Obviously it is not a substitute for looking over your shoulder when making a manoeuvre but the warnings of approaching vehicles is most welcome.

This device works and does its job.I am living in Istanbul / Turkey with one of the worst traffic environment in the world. I decided to start road biking from safe MTB worlds. I purchased this device for additinal safety for my rides and connected to my Wahoo Elemnt Bolt computer. which recgonize this device as Radar.this device is perfectly working and does its job. It starts warning as soon as a car is detected dozens of meters away. incredibly, it can detect cars where I am in turn and car is emerging at beginning of the turn. it can differentiate a car or other obstacles, for example, if I place my hand in front of radar, it does not sound alarm. or I can detect a car is moving from a park line between dozens of other cars are stopped and parked.It can detect multiple cars behind and shows them as different objects.so, I totaly recommend this Germin Radar, it is totaly worth money. I feel much more safe as I get a warning if there is something coming behing me. It keeps me alerted and be much more careful and focused.

Cycling around the quiet rural roads of S.France this has made a positive difference to my riding. No longer can following vehicles creep up on me. It can be hard to hear some cars that are surprisingly quiet but especially with wind noise. Paired to a Wahoo Elment Bolt the screen alerts are adequate. The orange LEDS for approaching work well and the Green for all clear are very helpful. The moving icon showing proximity is fine as well. Often a little procession of cars pass by, slow vehicle in front holding up a couple of others and it’s tidy to know when last vehicle has passed by - move out a bit and draft it! The light is very bright. Overall it just adds to my ability to be aware of what’s happening around me and provides a little bit more security - marginal gains!

I bought this light partly because I wanted to alert motorists to my presence but mostly because I wanted the radar functionality to make me aware of any vehicles approaching from the rear - for this function alone it's worth the cost! It works flawlessly and is able to identify cars that are close together, it shows on the screen (I sync with my Wahoo Elemnt Bolt) which also audibly notifies me so I always know when I'm about to be passed, it even gives a more urgent warning if someone is approaching quickly. Battery life is very good, lasts about 3-4 long rides (2-3 hours each).If I had the chance to go back and decide again whether or not to buy it I'd buy it in a heartbeat; highly recommended!

I paid £99 on a special offer. Honestly just buy it!! It’s incredibly accurate, well built, easy to use and increases not only your visibility but also helps you be more aware.Pros:1.It’s a light if nothing else. 60 lumin is bright enough don’t stress about 100 lumin lights, do you plan to be visible from space or something?2. Seamless connection to Garmin, turn it on and find the sensor than your done. Next time just turn your Garmin on and hey presto!3. It’s incredibly accurate, I mean what! How! It’s better than our eyes? Wait I don’t have eyes in the back of head.. now I do.Cons:1. No escaping it expensive, but remember you forget the cost of something you use and lot (this little guy) and remember the stuff you never use... my gopro YAWNN.2. Terrible in the city, constantly going off.3. It’s on the bigger side and I think (just me) it’s ugly as sin. But it’s the rider (or car) behind who’s looking at it so... Out of sight out of mind.To summarise, it’s the single best bike gimmicky thing I own which I love and now could not do without. I love my bikes and hate having junk on them. No stupid saddle bags or toptube bags I like a clean, slick, stealth, and light road bike that follows all the roadie rules. But **** it this makes the cut it’s that good.Ps shave you legs you’ll look both cooler and go faster on the bike ;)

This really is a great bit of kit if you're riding on generally quiet country roads, giving you advance warning if a car is approaching. I'm often surprised to find a car behind me if travelling at speed with some wind noise. It's really accurate and helps you to make that split second decision whether to choose the inside or outside edge around that pothole!I've tested it our on a couple of rides now and am very pleased with my purchase.If you cycle on busy roads I'd think it would be less helpful and possibly become annoying.Another thing to be aware of is that while the battery on the light is pretty good, it really drains the battery on your Garmin computer. I was out for 5-6 hours and the low battery warning message flashed up on my screen, while the light is supposed to have 15 hours in flash mode.

Très bon produit tient plus de 6 heures mais attention à la charge du compteur qui se vide plus vite. Impression que les voitures s'écartent davantage. Top.

Ottimo per la sicurezza, specialmente utilizzandolo con la Bici da Strada , nelle statali o in città

Livraison très rapide.très facile à monter, et très bonne visibilité de loin par les vehicules arrières.Radar TB sécurisant

Une précision étonnante et un outil de sécurité indispensable pour les cyclistes solo. Le prix est intimidant cependant.

J'apprécie le produit et justement je ne voudrais pas le perdre en chemin. Je trouve que le système d'attache Garmin manque de sécurité. Il devrais y avoir un système de clip pour bloquer le radar ou même le Garmin Edge. J'ai cherché le moyen de le retenir s'il se détachait (genre crochet avec ficelle) Car mon Garmin Edge s'était détaché en manipulant mon sac au dessus.
