TRACKR RADAR enhances visibility and situational awareness with smart radar and brake-reactive lighting

What Our Gearhead® Experts Are Saying:


"This light does more than shine—it communicates. The radar alerts are clear and helpful, and the brake light feature adds a whole new level of safety I didn’t realize I needed."


Designed for modern cyclists navigating unpredictable traffic, the Wahoo TRACKR RADAR merges powerful rear lighting with radar-driven safety alerts. Detecting vehicles up to 150 meters behind us, it sends real-time alerts to our Wahoo ELEMNT bike computer, select third-party computers, and fitness watches. Its adaptive lighting system not only reacts to braking with increased luminosity but also flashes to signal vehicles entering the detection zone, keeping us seen and safe.


The TRACKR's ANT+ Smart Light Control and Wahoo App integration provide streamlined customization for light modes, firmware updates, and safety feature management. An internal mode memory saves last-used settings, while Battery Extender Mode conserves energy when no vehicles are nearby. Its compact, road-ready form includes a quick-connect strap and quarter-turn mount, making setup easy across multiple bike types.


With an IPX7 waterproof rating and just 99 grams of weight, TRACKR RADAR offers a robust, intelligent rear visibility solution that’s designed to disappear into our ride while keeping us fully aware of what’s coming from behind.

Everyone should have one!

Familiarity:
I've put it through the wringer

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.

Excellent Tool

This device works great and is very sensitive to oncoming traffic. Would highly recommend to anyone riding on the road.

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.
