VoxRider gives your Bluetooth cycling radar a voice. Cyclists trust rear-view radar to spot vehicles approaching from behind. VoxRider adds the missing piece: clear, spoken alerts so you never have to glance down at your bike computer to know what's coming. WHAT IT DOES • Connects to your Bluetooth cycling rear-view radar • Speaks every threat aloud — number of vehicles, distance, speed, and threat level • Detects vehicles up to 140 meters behind you • Updates once per second, in real time • Stays connected in the background — keep the phone in your jersey pocket HOW IT SOUNDS "One car, 80 meters, medium threat." "Two cars, 40 meters, high threat." "All clear." You hear the threat picture without ever taking your eyes off the road. WHY VOXRIDER Visual radar displays force you to look down at exactly the wrong moment. Spoken alerts keep your attention where it belongs — on the road and traffic in front of you. VoxRider is built for cyclists who ride in mixed traffic, on rural roads with fast cars, or anywhere a head-check could cost a wobble. DESIGNED FOR REAL RIDES • Smart debouncing — no chatter when traffic is steady, only meaningful changes • Threat level always announced as the highest seen during the window • Alerts always finish speaking — never cut off mid-sentence • Adjustable speech rate • Works alongside your existing bike computer, headphones, or bone-conduction audio REQUIREMENTS • A Bluetooth Low Energy cycling rear-view radar • Bluetooth enabled on your phone • Headphones or speaker for audio output
