Use ANT+ Rear View Radar sensors with ELEMNT ACE, ROAM 3, or BOLT 3

ELEMNT ACE, ROAM 3, and BOLT 3 can pair with rear view radar systems (like the Garmin Varia or Trek CarBack) following the same pairing procedure as any other Bluetooth or ANT+ sensor.

For information on using third party radar units with legacy ELEMNT computers, see Using ANT+ Rear View Radar Sensors with [ELEMNT].

Requirements

Pairing an ANT+ Radar

  1. Turn on or waken the radar unit.

  2. Add a new sensor from the from the Ready to Ride sensor tray or the Sensors page (accessed by tapping the power button once and swiping left).
  3. If the ELEMNT does not prompt you to the radar, scroll down in the available sensors list. If there are a large number of sensors available, the sensor list will be divided by sensor type.  Radar units will appear under Other at the bottom of the list.
  4. Read and accept the safety warning statement.

Status

Shows as connected or not, and provides battery level.

  • Good - battery > 20%
  • Low - batter < 20%

Alerts

  • ON - Radar and visual and audio alerts are ON.
  • MUTE - Radar and visual alerts (radar lane) are ON, but audio alerts are muted / OFF.
  • OFF - Radar function is turned off, removing visual alerts (radar lane) and audio alerts OFF. 

Auto light

If the auto light feature is enabled (1S, 5S, or 10S), and the radar has a tail light, the light will default to off.  When the radar senses a vehicle is approaching, the light will be turned on to the last light mode selected on the taillight or the computer* and remain illuminated for the period of time selected (1, 5, or 10 seconds) after the last vehicle in a sequence passes and then turn off.  If the auto light feature is disabled (set to OFF), the currently selected light mode will perform as defined by the light mode.

  • OFF - Light presents the last light mode selected on the light or computer,
  • 1S - Light is off and turned on to the last light mode selected as a vehicle is approaching + 1 second.
  • 5S - Light is off and turned on to the last light mode selected as a vehicle is approaching + 5 seconds
  • 10S - Light is off and turned on to the last light mode selected as a vehicle is approaching + 10 seconds

*If used with a Wahoo TRACKR RADAR with the Quick alert light mode enabled, the light will turn on to a high flash mode while the vehicle is approaching, and return to the last light mode selected for the remaining 1, 5, or 10 seconds before turning off.

Radar Lane

  • LEFT - Radar lane / car track appears on the left side of display
  • RIGHT - Radar lane / car track appears on the right side of display

Light Mode

Dependent upon the radar's available preset light settings (ex. Off, High steady, Low steady, High flash, low flash)

Varia Radar performance specifications (as defined by Garmin)

  • The radar detects approaching vehicles up to 140m (153 yards) away.

  • The approaching vehicle speed must be from 10 to 160 km/h (from 6 to 99 mph).
  • NOTE: The radar does not detect vehicles traveling at the same speed as your bike.
  • The radar beam width is 40 degrees. It provides radar coverage for typical bends in the road.

  • The radar can detect up to eight approaching vehicles.

  • The vehicle position moves up the column as a vehicle gets closer to your bike. The threat level  changes color based on the potential level of threat.
    • Green indicates no vehicle is detected.
    • Amber indicates a vehicle is approaching.
    • Red indicates a vehicle is advancing at a high rate of speed.
      • A fast vehicle is detected (any vehicle faster than 90km/h (55mph) relative to the bike or any vehicle significantly faster than the average vehicle speed).

      • A slow-moving cyclist is being tracked behind you and a new vehicle is detected in the distance.
