Garmin has announced its new Edge 20 and Edge 25 bike computers – the smallest GPS cycling computers in the world.
Taking the title from Lezyne’s Mini GPS, Garmin’s new Edge 20 (£110) and Edge 25 (£140) head units are claimed to be the tiniest, and lightest, GPS-equipped models on the market, while still offering a full feature set.

Garmin has come up with a handy video to outline the features, which can be seen below:
The computers use GPS and GLONASS navigation satellites to give you data including speed, distance, location, time and total ascent. 
Despite their diminutive sizes, Garmin has also squeezed in routing capability. Riders are able to follow downloaded routes, giving a line to follow without full mapping, but with turn indications.
The Edge 25 also boasts ANT+ compatibility, allowing the addition of heart rate and cadence via compatible sensors. The Edge 25 can be purchased with a heart rate strap included for £170.
The more expensive unit also offers Bluetooth connectivity. This gives users the option of utilising live tracking, smart notifications and wireless uploads when paired with a smartphone. You can also share activities and upload to Garmin Connect immediately post ride. Edge 20 users will need to connect to a PC or Mac for upload.
Battery life is claimed at eight hours for both of the new Edge units.
Garmin’s vice president of worldwide sales, Dan Bartel, said: “Real estate on your bike is limited – the Edge 20 and Edge 25 are the quintessential bike computers for cyclists wanting to save space without losing valuable features.
“The Edge 20 and Edge 25 allow cyclists to track essential stats like time, distance, speed, ascent and location in a small but powerful device.”
The new Edge 20 and 25 units are sure to be a hit with weight weenies, while they could also benefit complicated time trial cockpits.
We’ll have the new computers in for review as soon as possible.
