Garmin 010-02376-00 Varia RTL515, Cycling Rearview Radar with Tail Light, Visual and Audible Alerts for Vehicles Up to 153 Yards Away

I am a amazed at how much this product enhances my riding experience. All those times where you need to look behind but its tricky because you are going fast downhill or concentrating on grinding in a climb are eliminated. One glance and you can see if there is a car coming up behind you. Huge safety boon. I highly recommend it!

This possibly the best bike accessory Ive ever bought. The radar and away this gives me on the road is incredible. It adds a lot of piece of mind and definitely improves safety awareness to both how you ride and to the cars behind you.

I love this device. It makes me feel safer (but not totally safe) on the road. Anything that appreciably adds to my safety on the bike is a welcome product. This delivers as advertised. Highly recommended if you are riding on country roads. Not sure it would be useful in a big city setting.

Picks up other cyclists, not just cars, which is quite annoying.

This connected to my Wahoo Element with no issues. Great to know when there is traffic behind you and when it is clear.

Four years ago, I got hit by a negligent driver and nearly died. So, I am more than a little safety conscious now. This light is worth every single penny you pay for it! It takes about ten seconds to install, and another few seconds to pair with your GPS head unit (I use the Wahoo ELEMNT Bolt). The light is powerful, and I love being able to “see” approaching cars via the head unit. I won’t ever ride on the roads again without this device!

Every cyclist that rides solo needs this device. It increases your safety 10 times

Very good product

Linked up with Wahoo Element and display is easy to understand. Con is that the rubber attachment is sketchy at best. My radar fell off during a ride and almost got run over by a truck followed me.

I do a lot of solo riding and early in the morning. This has made my riding so much safer by increasing my awareness of traffic from behind. So far I have had no issues with battery life. I have done 7 hour rides using the daytime flash mode and have never had the battery run out. I never go on a ride without it.
