Keep your focus where it belongs: on the road ahead. The Ebike Rear-Vehicle Alert System continuously monitors approaching traffic from behind and displays real-time vehicle alerts directly on your Monarc display. When paired with the Smart Helmet, audio warnings provide an additional layer of awareness without requiring riders to take their eyes off the ride.

• Real-time rear traffic monitoring and alerts
• Displays approaching vehicles directly on your bike display
• Color-coded distance indicators for quick awareness
• Smart Helmet integration for audio traffic warnings
• Simple Bluetooth pairing through your bike display or Monarc app

The Ebike Rear-Vehicle Alert System is designed to help riders stay aware of what's happening behind them without constantly checking over their shoulder. Mounted to the rear of the bike, the alert system continuously scans for approaching vehicles and sends real-time alerts directly to your Monarc display.

As traffic approaches, intuitive green, yellow, and red indicators provide a quick visual reference for vehicle proximity, helping riders maintain awareness while keeping their attention focused on the road ahead. The system can track up to five vehicles simultaneously and detect traffic approaching from up to 460 feet (140 meters) away.

For an even more connected experience, the Ebike Rear-Vehicle Alert System integrates with the Smart Helmet to deliver audio traffic alerts directly through the helmet speaker. Riders receive automatic warnings when vehicles approach from behind, allowing them to stay informed without looking away from the ride.

Powered directly by your ebike battery and connected via Bluetooth, the Ebike Rear-Vehicle Alert System pairs quickly through your Monarc display or the Monarc app and is built to perform in a wide range of riding conditions with an IPX6 water-resistance rating.

Compatible with all Monarc bikes.

    Alert system review

    I received the rear vehicle alert system as advertised, and it was very easy to set up. It easily connected to the bike and works great.

    Monarc Radar - Safer way to ride!

    Purchased prior to release and was a little hesitant it would be worth the investment. I was pleasantly surprised, really appreciate being able to “see” what’s behind me. With few dedicated bike lines in my area this was a great investment. Wish it did have an audio alert to the smart helmet but that’s my only suggestion

    Rear Vehicle Alert System

    I have had this accessory installed for about a week now and have gotten in five rides of at least 20 miles. It works great at detecting the cars coming up behind me while riding. I am fortunate to live in an area that is blessed with miles upon miles of rail trails. I can ride less than a mile from my house and excess trails with no cars and ride until my battery dies if I so desire.

    My only improvement would be to make the display colors more visible in the sunlight. They tend to get faded out.

    Bike is great, and I also got the helmet up and running last week. That is a game changer for taking calls and listening music and podcasts while still being able to hear traffic and alerts from other bikers passing by.

    I highly recommend this bike and accessories to all. I have ridden lots of e-bikes in the past ten years and my Tracer takes the cake by far.

    Best,

    Mark
