Description
The Trek Accessories App adds additional functionality to the Trek CarBack Radar Rear Bike Light by giving cyclists advanced alerts and a real-time visual depiction of rear approaching detected vehicles.

Helps you see cars.

Use the Trek Accessories App to receive visual and audible alerts of detected rear approaching vehicles. The Trek Accessories App and Trek CarBack Radar can detect rear approaching vehicles from up to 240M, with vehicles first appearing with an audible beep and a visual indicator at the bottom of the App screen. Once the detected vehicle approaches to within 150M, the vehicle is shown on screen in real time. Once within 75M the Vehicles location is depicted in both distance behind and distance to either side, indicating preparation for a potential pass. Once the vehicle completes a pass, an audible alert indicates the pass and the vehicle drops off the screen.

Helps cars see you.

The Trek Accessories App also gives the ability to turn on a connected Trek CarBack Rear bike Light, all from the App screen. The CarBack Radar offers Daytime Running Light Performance that can be seen from up to 2km during the day to help a cyclist be more visible on the road.

Audible and Visual Alerts

You can choose the best way to receive alerts – Alerts will be shown visually on screen as well as an audio alert when a detected rear approaching vehicle is first detected, and again when it passes. You can choose to turn audible alerts on and off. This allows you to use the app the way you ride – either with a phone mounted on your bike’s handlebars, or stowed in a jersey pocket.

*Please note that the Trek Accessories App currently only works with Trek CarBack Radar Rear Bike Lights.

Comments on Trek Accessories for Android

★★★★☆ Kellan Reierson · Jun 2, 2024
Works great at detecting cars. Only issue is I wish the notification sounds could be changed and there be more notification types. For example if there was a different sound for a car close and not in the passing zone. Also, the all clear sound is hard to hear compared to the carback sounds.
★★★★★ Hector Montanez · Oct 5, 2025
Has great distance compared to the Garmin that has better peripheral then the Trek, by than the vehicle is right next to you which is too late in my books. Kudos 👏 to the Trek Carback.
★★★★☆ Larry Miller · Jul 21, 2024
Pretty good. Other than app alerts me decive disconnected when I turn the unit off. I have to force stop the app to get it to stop.
★☆☆☆☆ Draff O · May 13, 2024
Carback screen goes dark after app running for 30 seconds. Have disabled screen timeout/Screensaver no change. The app itself is going into a dark screen setting and is too dark to read.
★☆☆☆☆ Tim Rapp · Jul 13, 2024
App (Android) only displays a line drawing of the carback with no other features and will not detect or pair with the device. Trek pairing instructions cannot be followed due to app not working.
