If you prefer a simple GPS cycling computer for tracking your speed and distance and sharing rides through a favorite social training website like Strava, the brand new Garmin Edge 20 is quite simple to use, compact and a decent battery life.

The Edge 20 GPS cycling computer costs £110. The more feature-packed Edge 25 (recently reviewed on road.cc – browse the review here) costs £140. That £30 difference sees the cheaper Edge 20 do without Bluetooth and ANT+ compatibility, which can not seem to be like much, but means you can’t use a heartrate or cadence sensor with it. And for a few, that may be the offer breaker which makes the Edge 25 the better long-term investment.

Those distinctions aside, the Edge 20 looks and functions identically to the Edge 25. If you prefer a GPS cycling computer which means you may easily track basic metrics like speed, distance and elevation, and also easily upload to the net, using either Garmin Connect or the third-party training tools, the Edge 20 works a delicacy. And since it uses GPS, it’s completely wireless and simple to swap between different bikes, without setup required out from the box.

It’s tiny, barely any bigger compared to the mount, and looks great on the stem. It measures 4 x 4.2 x 1.7cm with a 2.3 x 2.3cm screen. It’s light aswell, just 25g. Garmin’s own quarter-turn mount hardware is a doddle to use and it will work with the multitude of aftermarket mounts.

The battery is charged with a special cradle that clips to the trunk of the computer, and the USB lead also uploads your activities to the net. The more costly Edge 25 lets you sync it with a compatible smartphone via Bluetooth, so that you can upload rides without going anywhere near a computer. Battery life is a claimed eight hours and we got pretty near that in testing.

The display is sharp and displays just the info it is advisable to see. You get two data screens showing whatever you really need if you are riding. It’s simple to switch between your screens when riding.

There are four buttons on the machine, to turn it on / off and navigate through the available menus. It is rather intuitive to use, no manual is necessary, and after a short while you have the way of measuring these devices. The buttons are simple to use with gloves aswell.

The most notable left button switches the Edge 20 on. The most notable right button may be the OK button, as the lower left button goes back a screen. The low right button scrolls down (you can only just scroll down) through the menus and options. the house screen presents you with Ride, and you will very quickly go directly into action. Scroll down if you wish to gain access to your previous activities or adapt any settings.

While there is no actual navigation just like the bigger plus much more expensive Edge 1000, the course mode does permit you to download a route from Garmin Connect and follow a breadcrumb trail. It isn’t as easy as carrying out a map, but does keep you on the right course.

Conclusion
The Edge 20 is an extremely good GPS cycling computer that’s simple to use, light, compact, and with a decent battery life. However the insufficient ANT+ and Bluetooth compatibility does make the excess £30 for the Edge 25 an improved buy if you wish in order to harness heartrate or cadence data.

However, the price tag on a heartrate strap, unless you already have one, must be considered. A Garmin heartrate monitor will probably cost you at least another £25 in addition, so you might be looking at practically £60 merely to add heartrate data. If you are sure you’re never likely to want to employ a heartrate monitor, the Edge 20 will be just fine. If you feel you might 1 day want to upgrade, you’re better off purchasing the Edge 25 to begin with.

Verdict
Small and simple to use, but insufficient Bluetooth and ANT+ compatibility is a limiting factor
