Features & Capabilities

The Trek Accessories App extends the Trek CarBack Radar Rear Bike Light by providing real-time alerts and a live visual depiction of rear-approaching vehicles. It detects traffic from up to 240 meters away, first signaling with an audible beep and a small on-screen indicator. As the vehicle closes to 150 meters, it appears on the screen in real time, and within 75 meters the app shows distance behind and distance to the sides to help you anticipate a pass. When the pass completes, an audible alert confirms it and the vehicle drops off the screen.

The app also lets you turn on a connected Trek CarBack Rear Bike Light and leverages daytime running light performance for visibility up to 2 kilometers. Alerts can be shown visually or spoken aloud, and you can turn audible alerts on or off to suit your ride, whether a phone mounted on the handlebars or stowed in a jersey pocket. Note: The Trek Accessories App currently works with Trek CarBack Radar Rear Bike Lights.

Love the app but 2 request. Can you please add Apple Watch support to this app? I use Ride With GPS and I like to keep my iPhone on that app so it would be nice to see the CarBack info on my watch. Additionally, can you add support for Ride With GPS so I again I can see car data within the Ride With GPS app.

This app connects easily to your CarBack radar, showing its power and battery status and letting you turn the audio on or off as desired. If you mount your iPhone on your handlebars, you get a nice live map showing detected cars relative to you. (It only supports portrait/vertical display, FYI.) But except for mute/unmute, there is no control over the sounds or their volume. That really matters if you don’t have the visuals from a bike computer or a handlebar-mounted iPhone. The alert tone is fairly audible when your phone is in a pocket or saddlebag, but the all-clear tone is not audible unless you are not moving— it takes very little road or wind noise to drown it out. The alert tone is more audible but can also get drowned out by strong road and wind noise. Control over alert volume and choices over the tones themselves are needed so you can get the best audio based on your ride conditions and your own hearing (what you can hear changes as you get older!). There is no Apple Watch support to make the radar status more accessible when you have no mounted phone or bike computer. Because the CarBack hangs on to the Bluetooth connection with your phone even after you turn it off with its physical button, you can get surprise alerts that the CarBack is no longer detected long after you turned it off. This seems to be antitheft feature, such as for when you park your bike for a break during a ride, but you can also get alerted at home when you are done with your ride and are no longer in range. This feature needs more thought.

App works perfectly, pairs up instantly with the radar/ light, helps keep me safe on the road. Highly recommend.
