Ah, the perennial question (for a sub-set of road cyclists with a penchant for data and a secret desire to be a pro rider): which bike GPS to invest in?
Garmin ‘owned the space’ for many years. In recent years, competing up-starts have parked their tanks on Garmin’s lawn (with great accuracy, if they use GPS). Leading amongst these is Wahoo with its ELEMNT series of devices.
In this post I compare the Garmin Edge 520 and the Wahoo ELEMNT BOLT, both of which I bought (last year I think) and have used extensively.
Bike GPS devices these days have lots of features. The differences across models and between manufacturers are many. I will endeavour to restrict this highly analytical report (opinion piece based on little hard evidence) to the key differences that I think are relevant to enthusiast road cyclists (such as your good self).
