More than just a high tech version of the small mirrors you have seen attached to some cyclists helmets.  The Garmin Varia does more than just warn you of oncoming traffic via, in that it also sends a signal to drivers.

  • Works independently and wirelessly integrates with compatible Edge® cycling computers¹
  • Edge computer or Varia head unit can detect multiple vehicles and indicates the relative speed of approach and threat level
  • Tail light unit brightens and flashes to notify approaching traffic of a cyclist ahead


varia interface

The Haiku uses a touchless interface which is great when riding as you don’t want to be searching whilst barreling down your local bike path or negotiating traffic.  I also like the added details on the display backed up with easy and quickly recognisable LED’s that can be seen in your periphery

Problem statement:

According to Garmin advertising getting hit from behind is the largest cause of cycling fatalities in the United States of America.  I am not sure how the stats compare in Australia but there have been numerous “dooring” incidents in the last few years that have forced cyclists into the drivers path howver anything that can increase drivers awareness is a good thing and is the main reason I designed by bags.  I would need to try one of these out to understand if it is possible to adjust your own riding habits through the edge computer warnings or if I would spend cycling commutes panicking as a car approached
