Rear radar

Your bike radar, on your phone. Free.

Drafto connects to your rear radar over Bluetooth. Vehicles coming up behind you appear along the edge of the screen, with a sound, and a voice when it gets dangerous. No bike computer needed.

Rear radar: a car at 64 m

During the ride

See and hear what’s coming up behind you.

The bar

During the ride, a bar on the right edge of the screen shows approaching vehicles: green when the road is clear, orange when a vehicle is coming, red when it is coming fast.

Sounds and voice

A beep announces each new vehicle, two rising notes the clear road. If a vehicle approaches fast or close, the phone vibrates and a voice warns you, even with the voice coach off.

The distance

The “Rear radar” tile shows the distance to the closest vehicle. It disappears when the road is empty.

The rear radar is free

It’s a safety matter. Heart rate straps, power meters, cadence and speed sensors are part of Premium.

Getting started

Three steps, once.

  1. Drafto works with Garmin Varia radars. The first time, put the radar in pairing mode: switch it off, then hold its button for two seconds until the LED turns purple.
  2. In “Sensors”, start the scan and pair the radar. After that, it reconnects by itself on every ride.
  3. Start your ride: the radar bar appears along the edge of the screen.

A radar already linked to a bike computer refuses any other connection: its blue LED shows it. If the app asks you to put the radar in pairing mode, repeat step 1.

Questions

You might be wondering…

Do I need a bike computer?

No. Your phone is enough: Drafto connects straight to the radar over Bluetooth, with no bike computer or other app.

Which radars are compatible?

Garmin Varia radars, and those that speak the same Bluetooth language: Bryton Gardia, Magene, iGPSPORT.

My radar is already linked to my bike computer. Will it work?

A radar already linked to a bike computer refuses any other connection: its blue LED shows it. If the app asks you to put the radar in pairing mode, repeat step 1.

Is the radar really free?

Yes, with or without Premium. It’s a safety matter. Heart rate straps, power meters, cadence and speed sensors are part of Premium.

Can I turn off the beeps or the voice?

Yes, in the voice coach settings: vehicle announcements, beeps and vibration are set separately. The radar stays free and active: these three settings only change how it warns you.
