Knowing a car is approaching before you hear it changes how you ride. The Wahoo TRACKR RADAR detects vehicles up to 150 meters behind you and sends that information to your bike computer or compatible watch as both visual and audible alerts. You get warning well before the vehicle reaches you, time enough to adjust your line, signal to riding partners, or simply prepare for the pass rather than being startled by a close overtake.

The radar broadcasts via ANT+ to ELEMNT computers and other compatible devices from Garmin, Hammerhead, and others that support the ANT+ radar protocol. On Wahoo's ELEMNT units, you'll see approaching vehicles displayed on screen with distance indicators that update in real time, plus configurable audio alerts. The unit pairs through the Wahoo app for firmware updates and feature configuration, though the app itself doesn't receive riding alerts since those require ANT+ communication with a head unit.

Dual LEDs distinguish the TRACKR RADAR from single-LED competitors. The primary light sits at top center, while a secondary LED at the bottom also throws light to the sides for improved visibility from oblique angles. Four light modes span high and low versions of both steady and flash patterns, with the high flash mode pushing 53 lumens. Battery Extender mode automatically dims output when no vehicles are detected, conserving power on quieter roads without requiring you to toggle settings mid-ride.... Read More
