Trek Accessories 4+

The Trek Accessory 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 Accessory App to receive visual and audible alerts of detected rear approaching vehicles. The Trek Accessory 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 Accessory 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 Accessory App currently only works with Trek CarBack Radar Rear Bike Lighs.
