BikeBack: Bike Radar Callouts

Your bike computer beeps for segments. It beeps for turns. It beeps for climbs, laps, and hazards. Somewhere in that chorus is your radar saying "a car is approaching" — and you might miss it.

BikeBack speaks up instead. The moment your bike radar detects a vehicle, BikeBack tells you in plain English: "car back, 50 meters." When the road is clear, it tells you that too.

Cyclists have always shouted "car back!" to warn each other. BikeBack does it for you — automatically, every time, hands-free.

WHAT IT DOES

• Connects to a Bluetooth cycling radar
• Announces approaching vehicles by distance: "car back, 50 meters"
• Calls "all clear" when traffic has passed
• Works with your phone in your jersey pocket, screen off
• Mount on your handlebars and see a visual radar lane with each vehicle's distance, speed, and threat level
• Pairs with any Bluetooth heart rate strap for spoken zone or BPM announcements
• Plays through your phone speaker, headphones, or any Bluetooth audio device

WHY SPOKEN CALLOUTS

A spoken "car back, 50 meters" is unmistakable, even when your bike computer is chirping about something else. You hear it, you know what it means, you keep riding.

Spoken alerts also let you keep your eyes forward and your hands on the bars — exactly where they should be when traffic is approaching.

DESIGNED FOR REAL RIDES

BikeBack runs in the background while you ride. No accounts. No signup. No tracking. Pair your radar, start your ride, and forget the phone is there.

HEART RATE MONITOR

Pair any standard Bluetooth heart rate strap alongside your radar. BikeBack announces zone changes or speaks your BPM at regular intervals. Heart rate alerts blend with radar callouts without interrupting them. Ride with just an HRM and no radar -- BikeBack handles either sensor on its own.

WHAT YOU NEED

• An iPhone with Bluetooth
• A Bluetooth cycling radar (rear-view bike radar)
• Optional: Bluetooth heart rate strap
• Optional: Bluetooth headphones or speaker

PRIVACY

BikeBack does not require an account. It does not collect personal data, track your location, or send your ride information anywhere. Radar data stays on your device.
