The Garmin Edge 850 is a superb bike computer, but the Edge 550 is the company's best-kept secret—now $100 off in the Prime Day sale

Save for a touchscreen and a few extra creature comforts, there's no reason to avoid the Garmin Edge 550 this Amazon Prime Day - it's a brilliant cycling computer

I loved the Garmin Edge 850 I reviewed last year, lauding it for its screen and feature-rich user experience. While it's no doubt one of the best bike computers on the market, there's another stellar option from the American technology giant that lurks in its shadow - the Garmin Edge 550.

With a user interface much like its Edge 850 sibling, the Edge 550 is up to the task and offers a detailed, intuitive cycling experience. I've currently got the Edge 550 on test, which, consequently, I'm nearly ready to wrap up. As it stands, it's Garmin's best-kept secret.

Similar to the Edge 850, the Edge 550 gets a highly responsive 2.7-inch full-colour, transmissive LCD screen - both models look basically identical thanks to sharing the same hardware dimensions of 54.6 x 92.2 x 16.8 mm. The differences come in the form of features, including a touchscreen, a small speaker for navigation prompts, a digital bike bell, Garmin Pay, and double the storage (64GB vs 32GB)—none of which is imperative for the cyclist, but are nice-to-haves.

Currently, the Edge 850 and 550 can both return 12 hours of battery life during intensive use, and up to 36 hours in battery saver mode.

At 20% off retail, this is certainly not the first or the biggest discount we have seen on some of the latest Edge models; however, if you are looking for the latest bike computer tech, it is not insignificant and is easily one of the best bike computers currently available.

With a 17% savings, this Amazon Prime Day Garmin Edge 850 deal is also one not to miss. It's easily Garmin's best-kept bike computer, jam-packed with all the features you'll ever need.

Yes, the 850 Edge gets a touchscreen and a couple of other little novelty features, but I much prefer the tactile experience of buttons - plus, there's also no chance of accidentally deleting your ride (as I've done many times with my own Garmin Edge 850). Call me a purist, or maybe I'm too obsessed with Strava and don't want to lose any of my logged rides.

Anyway, I'm currently using the Edge 550 for all my time-trial races and hard sessions. This is because I do find that sweat can cause "ghost touches" on touchscreen bike computers, as it's highly conductive.

Take it from a cycling tech tester: you'd be crazy not to consider the Garmin Edge 550. It's reliable, easy to use, has one of the best screens in the game, and is now available at a seriously impressive discount. Go on, buy it - you won't regret it.
