TL;DR
- Buy the Garmin Edge 550 ($499.99) if you ride familiar routes and want buttons that work with any glove; buy the Edge 850 ($599.99) if you build routes and workouts on the unit or explore new roads.[1]
- The hardware that matters is shared: a bright colour display, multi-band GPS with 5 Hz recording in the enduro and downhill profiles, a speaker-driven bike bell, and the same battery rating of up to 12 hours in demanding use or 36 in battery saver.[1]
- The $100 buys a touchscreen. The 850 adds touch on top of the buttons, which makes creating courses on the device practical.[1][2]
- They replaced the Edge 540 and 840 in September 2025. The brighter display costs battery against those older models.[2][4]
The Edge 550 and 850 are Garmin's compact cycling computers, separated by $100 and one decision: touchscreen or not. They share the display, GPS, battery and Garmin's training features, so this is not an accuracy contest; it is about how you interact with the unit. Garmin no longer lists the Edge 540 and 840 on its store; it lists the 550 and 850 from $499.99, below the $699.99 Edge 1050.[3] Every figure here comes from Garmin's pages or a published spec sheet, checked on 2026-10-18.

What the $100 buys
The headline difference is the touchscreen. The Edge 850 adds touch on top of the button array, so you can pan maps, create courses on the device and see road surface types while planning, without a phone.[1] If you explore unfamiliar roads, reroute often or build structured workouts on the unit, that is worth the money. Everything else that shapes a ride, from GPS and battery to radar support, weather overlays from your phone and eBike integration, is the same on both.[1]
Where the 550's buttons win
Button-only control is not purely a downgrade. Buttons stay reliable with heavy winter gloves and in rain, where a touchscreen can misread. Riders who train on familiar routes, follow courses and workouts pushed from a phone or training platform, and ride through the cold get everything they need from the 550, with the same display, GPS and battery, for $100 less.[1]
The battery trade against the old 540 and 840
Garmin's brighter transmissive display is the reason both models are rated for up to 12 hours in demanding use and 36 in battery saver, which is noticeably below the Edge 540 and 840 they replace.[1][2] For most rides that is plenty. Ultra-distance riders should look at the Edge 1050 (up to 20 hours, 60 in saver) or the Edge 1040 Solar instead; see Garmin Edge 1050 vs 550.[3]
Which to buy
- Familiar routes, gloves, workouts pushed from an app: Edge 550.
- Exploring, rerouting and building courses on the unit: Edge 850.
- Very long days in the saddle: Edge 1050 or Edge 1040 Solar, for the battery.
- A cheaper mapping unit: Edge Explore 2 at $299.99.[3]
The short version: the 550 is the better value if buttons suit how you ride; the 850 is worth $100 more if you plan and change routes on the bike.
