The Edge 20 is the entry point into the Garmin range and a computer launched in June alongside the Edge 25.

It’s also the smallest computer in the range, though shares the same 4cm x 4cm x 1.7cm unit dimensions (and 2.3cm x 2.3cm screen) as the Edge 25, and the water resistant unit is designed to sit inconspicuously on the handlebar or stem.

The Edge 20 offers much of the simple functionality of a traditional bike computer in recording basic data like distance, speed, riding time and the like, but gets its information through GPS rather than a magnet on the bike’s wheel. That essential information is displayed on three lines of customisable data. There’s no ANT+ connectivity – that’s reserved for the Edge 25, which we’ll come on to.

Users can also download courses through Garmin’s Connect software and follow basic turn-by-turn indications or breadcrumb trail on the screen.

As well as using GPS, the American satellite system, the Edge 20 also locks on to the Russian GLONASS system in order to increase the speed at which the computer finds a satellite and the accuracy of data. Battery life is up to a claimed eight hours.
