At a glance
Short answer: Pick the Wahoo ELEMNT ROAM 3 ($464.99) to save $135 and set it up from your phone. Pick the Garmin Edge 850 ($599.99) for the sharper screen, crash alerts, training extras and Shimano Di2 or SRAM AXS support.

Which one fits you
- Lower price, phone-first setup: ROAM 3. You set it up in the Wahoo app; Wahoo says functionality is "extremely limited without it".
- Training plans, crash alerts, Garmin Pay: Edge 850. Garmin lists Garmin Coach plans, daily suggested workouts, incident detection, a bike alarm and Garmin Pay contactless payments.
- Electronic gears: Edge 850. Garmin lists Shimano Di2 and SRAM AXS integration; Wahoo's ROAM 3 pages don't mention shifting.
- Wahoo KICKR at home: ROAM 3. Wahoo says it can control "all KICKR smart bikes and smart trainers".
- Comparing more models: see GPS bike computers by price. Black Friday is 27 November; the Black Friday price watch is worth a look first.

Sources and notes
Where the sources disagree
- ROAM 3 maps. Wahoo's Product Information page says "World maps available for free download via Wi-Fi". Wahoo's setup page says "ELEMNT ROAM 3 ships with all world maps, complete with all map layers". Either way the maps cost nothing; the table says "Free world maps".
- ROAM 3 in the box. Wahoo's US store lists an out-front mount (31.8 mm), USB-C cable (61 cm), 190 mm tether, stem mount and zip ties. The support page lists the computer, a "Plastic Out-Front Mount (for 31.8 mm round bars)", a "USB-C > C charging cable" and an "Important Product Info Guide", with no tether or stem mount.
- ROAM 3 weight. The US store says "3.8 oz"; the support page says "3.8 oz // 109g". These agree (3.8 oz is about 108 g); the table uses Wahoo's gram figure.
What we could not confirm
- A like-for-like battery comparison. Garmin quotes "demanding use" and battery saver mode; Wahoo quotes one "up to 25 hours" figure with the footnote "Battery life can vary depending on usage, such as backlight brightness, settings, and the number of connected sensors." Neither page gives a test method, so the hours are not directly comparable.
- ROAM 3 and electronic shifting. Not mentioned on Wahoo's US store or the two support pages we read. That doesn't mean it can't; Wahoo just doesn't say there.
- Warranty. Neither US product page showed a warranty term on 2 November (Wahoo's EU store shows "2-year warranty", which reflects EU law).
- Out-the-door cost. Sales tax depends on your address. Garmin showed "Available to ship in 1–3 business days"; Wahoo showed "Fast delivery" and "30-day returns" with no shipping dollar figure.
Price checks and caveats
- Price checks: Garmin's US store showed the Edge 850 Touchscreen Edition (part number 010-03023-00) at $599.99 USD with no sale price. Wahoo's US store showed the ROAM 3 at $464.99; Wahoo's EU store showed €449.99.
- Size: Edge 850 54.6 x 92.2 x 16.8 mm; ROAM 3 96 x 53 x 24 mm. GPS: Garmin says "Multi-band GNSS", Wahoo says "dual-band". Both mean the unit listens to more than one satellite signal for better tracking near tall buildings and trees.
- In the Edge 850 box, per Garmin: the computer, a flush out-front mount, a standard mount, a tether, a charging/data cable and documentation.
- Why this pair: they are the mid-size touchscreen models from the two brands, $135 apart. We looked at Garmin Edge 1050 vs Hammerhead Karoo first, but SRAM's store showed the Karoo as "Unavailable" on 2 November.
