Tips for Installing the Device

The Varia Rearview Radar RTL515 device includes a taillight and micro radar that can detect approaching vehicles up to 140 meters away.

  • Select a secure location to mount the device where it does not interfere with the safe operation of your bike.
  • Mount the device as high on the seat post as possible for optimal light visibility and radar detection.

    NOTE: The mount surface should be vertical. The mounts are designed to accommodate most seat post angles.

  • Mount the Varia RTL515 device on the seat post 250 mm to 1200 mm above the road.
  • Install the device correctly.

    The device faces backward and is perpendicular to the road.

  • Make sure there are no obstructions in front of the light.
  • Go for a test ride during the day in a safe environment.
