TRACKR RADAR keeps you visible and alerts you to vehicles behind, so you ride with focus
What Our Gearhead® Experts Are Saying:
"I’ve tested radar lights before, but the TRACKR RADAR is the cleanest integration I’ve seen—it links seamlessly to my ELEMNT computer, ramps brightness when I brake, and gives peace of mind on traffic-heavy roads."
Whether we’re hitting sunrise segments or grinding through evening commutes, we ride with more confidence knowing the TRACKR RADAR has our back. This smart rear light and radar combo alerts us to approaching vehicles up to 150 meters away, while its adaptive lighting and brake-responsive illumination ensure we’re visible and in control at all times.
It’s built to integrate effortlessly with Wahoo’s ELEMNT bike computers and compatible devices, pushing real-time alerts without pulling our eyes from the road. The sleek, compact form mounts easily on nearly any bike, and the IPX7 waterproof rating ensures it keeps working, even in a downpour. TRACKR RADAR isn’t just a light—it’s situational awareness, simplified.

Everyone should have one!
- Familiarity:
- I've put it through the wringer
- Size Bought:
- One size
Game changer if you log a lot of road miles - especially with super quiet EVs around. Works really well and gives great audio and visual (ELEMNT Roam 3 head unit) cues. No issue with duration of charge or recharge time. Also, smaller than you think.

A great safety product
I love my new Trackr Radar. It works great, gives me a heads up for traffic coming up behind me and synced seamlessly with my Wahoo Elemnt. I can't imagine riding without it.

Great to know when a car is approaching!
This is my first radar device and it is so helpful to know ahead of time when a vehicle is approaching, so I can make an effort to hug the side of the road when necessary. I highly recommend this if you already have a Wahoo computer - why wouldn't you want this? Thank you Wahoo!

Wish there was a more comprehensive user guide
1. Wish there was a more comprehensive user guide 2. Seems to have a longer battery life than Garmin Varia Radar light. 3. The light is not showing at the end of a ride after I end my ride on my Garmin Edge 1050. I am guessing it is working till then. 4. Difficult to know if is off or standby after recharging

Works great, but…
I’ve used it for a couple of weeks. I give it “5 Stars” for ease of use and integration with my Element Roam. It works as advertised, identifying vehicles coming up on me, and is quite good at it - another “5 Stars. ” It’s so good at it that it also identifies other cyclists behind me. If I’m riding with a group that’s annoying, as the alarm goes off repeatedly. I won’t use it for group rides because of that, which decreases its utility for me. That fact drops my rating to “4 Stars. ” The mount works great, but is proprietary - 4 stars. The last thing I’d say is out of the box, without me fiddling with settings, the battery life is not very good. I often go on 40 - 50 mile gravel rides, which puts me in the 3 to 4 hours of use. The battery doesn’t last that long. I’ll look into different settings to see if I can get longer life out of it. But 2 hours or so of battery life is not very useful for me - 2 Stars. I’d say it’s a good product if you’re into rides that last less than 2 hours. You’ll be charging it after every ride. Overall I’d give it 3 stars. I’m a bit disappointed to be honest.

So when I first saw
So when I first saw the Trackr Radar my first thought was “kinda pricey for a tail light “ boy was I in for a surprise! And of course you always want to check blind spots, keep your head on a swivel, and practice all the rules of the road!! But this little gem is a game changer!! The radar displays on your wahoo computer in a very intuitive way with sounds, and color changes to let u know what’s coming. In high traffic it will be going quite a bit and it can be helpful but where I feel it really shines for me is on the rural roads with not much traffic. Can’t say enough about it I would suggest it to anyone who wants more peace of mind out on road!

Easy to use
This radar just works. The straps to attach it could be a bit longer.
