Helps you see drivers
CarBack’s focused radar helps detect rear-approaching vehicles from up to 240 m away.
Smartphone- and GPS-compatible
You can pair CarBack with most major GPS cycling computers, GPS sport watches and your smartphone using the Trek Accessory app.
Visible battery gauge
A four-bar LED battery gauge makes it easy to know when it’s time for another charge.
Waterproof USB-C charging port
A waterproof IPX7 rating helps protect your CarBack in wetter weather, and USB-C charging is quick and convenient.
Compact design
CarBack’s smaller profile fits on smaller frames and on bikes with saddle bags.
Audible and visual alerts
Pair CarBack with your phone and the Trek Accessory app and choose how you get alerts. Keep the app screen open for a visual display of detected vehicles or run it in the background with audio alerts alongside your favourite ride-mapping app, or from your phone safely tucked into a jersey pocket.
