Pros & Cons

Pros & Cons

  • The Trek CarBack Radar gives you both audio and visual cues to warn you about rear-approaching traffic (from up to 240 meters away).
  • Ideal for use in a city environment and during the day: you'll be visible from 2 kilometres away when you're using the brightest flashing mode.
  • The combination of a radar and high-end rear light makes cycling a lot safer.
  • This radar is charged using USB-C, has a battery life of over 7 hours and features LED indicators to notify you about its battery's status.
  • Comes with USB-C charging cable and Quick Connect Plus rear bike light mount.
  • The daytime running lights can blind other people on the road if you use it in the dark.

The best light to be seen by far and at a good price.

- David 14 February 2026

I'm happy with it, for now, I've only had it for a short time. But it makes a brutal light. The battery lasts a long time.

Good vehicle detection

- ROBERTO 21 January 2026

The device is good, it detects cars very well on the road but going out of the city is horrible because it whores constantly, it should have a "mute" mode for these cases.
