Garmin Edge 550 vs Wahoo ELEMNT BOLT 3: which bike computer fits you
Two button-only bike computers, $150 apart.
At a glance
Short answer: Get the Wahoo ELEMNT BOLT 3 ($349.99) to save $150 and get a smaller, lighter unit you set up from your phone. Get the Garmin Edge 550 ($499.99) for the bigger screen, maps already loaded, and extras like incident detection (crash alerts).
Who it's for: road and gravel riders buying a GPS bike computer in the $350 to $500 range.

Which one fits you
- Lowest price, lightest unit, phone-first setup. Wahoo ELEMNT BOLT 3 at $349.99.
- Bigger screen and maps ready out of the box. Garmin Edge 550 at $499.99.
- Long days. Hard to call from the claims, since the two brands state battery life on different bases (see the notes). Garmin's 36 h figure needs battery saver mode.
- Di2 or AXS bike and you want the shifters to work the computer. Edge 550; Wahoo doesn't say on these pages.
- Already on a Wahoo KICKR trainer. BOLT 3 fits the same app and controls the trainer.
- Comparing more models. See GPS bike computers by price. Black Friday is 27 November, so the Black Friday price watch is worth a look before you buy.
Price and what's in the box
Garmin Edge 550. Garmin's US store showed $499.99 for the Standard Edition (part number 010-03022-00), with no sale price, and "Available to ship in 1–3 business days." In the box: the Edge 550, a flush out-front mount, a standard mount, a tether, a charging/data cable and documentation.
Wahoo ELEMNT BOLT 3. Wahoo's US store showed $349.99, with "1-year warranty" and "30-day returns" under the price. Wahoo's "What's Included" list: the BOLT, an out-front mount (31.8 mm), a USB-C charging cable (24 in / 61 cm), a 7.5 in (190 mm) tether, a stem mount and zip ties. A spare out-front mount or an integrated handlebar mount is $29.99 each on the same page.
So the gap is $150 before tax, and both come with a mount that holds the computer ahead of the bar.
Day-to-day use
Setup. Wahoo puts the settings in your phone: profiles, data pages and sensors are set up in the Wahoo app. Wahoo's support page says "Due to the lack of a touchscreen, BOLT 3 relies on your phone's keyboard for some more complex control interactions." The Edge 550 is also button-only, and Garmin pairs it with the Garmin Connect app for phone features like weather and LiveTrack (a live location link for family).
Navigation. Both give turn-by-turn directions and can get you back to your route or back to the start. The Edge 550 comes with TopoActive maps and Trailforks trail data loaded, and Garmin adds more maps for free over Wi-Fi. Wahoo says the BOLT 3 offers "World maps available for free download via Wi-Fi", and it can build a route from a place you share from Apple or Google Maps on your phone. Wahoo also syncs routes from Komoot, Ride with GPS, Strava and Trailforks.
Training. Garmin lists Garmin Coach training plans, daily suggested workouts, real-time stamina, power guide and fueling alerts; several of these need a heart rate monitor or power meter. Wahoo lists structured workouts imported from more than 100 training providers, Strava segments, and SUMMIT climb pages, which Wahoo says work even without a loaded route.
Safety. Garmin lists incident detection (a message with your location to emergency contacts after a crash, when paired with your phone), a bike alarm and road hazard alerts from other riders. Both brands list control of rear radar and lights: Garmin's Varia line on the Edge, Wahoo's TRACKR RADAR and others on the BOLT.
Indoor and electronic shifting
Both can run a smart trainer. Garmin's manual says the Edge 550 pairs with a trainer over ANT+ and can set resistance while you follow a course or workout. Wahoo lists ANT+ FE-C (the standard way for a computer to control a trainer) and says the BOLT 3 can control all KICKR smart bikes and smart trainers.
For electronic gears, Garmin's manual says the Edge 550 pairs with Shimano Di2 and SRAM AXS shifters, and the shifter buttons can control the computer. Wahoo's BOLT 3 pages we checked don't mention shifting.

Sources and notes
Spec terms and caveats
Multi-band or dual-band GPS listens to more than one satellite signal; Wahoo's page sums up the point as "Dual-band GPS for accurate tracking in built-up terrain". ANT+ and Bluetooth are the two wireless links bike sensors use. IPX7 means it survives rain and a short dunk: Garmin's manual says incidental exposure to water up to 1 m for up to 30 minutes.
Where the sources disagree
- BOLT 3 battery life. Wahoo's store page tech specs and its support page say "up to 20 hours". The FAQ on the same store page says the BOLT 3 has "longer battery life at 25-hours* for all-day riding", with the footnote "Battery life can vary depending on usage, such as backlight brightness, GPS settings, and the number of connected sensors."
- BOLT 3 weight. Wahoo's store page: "Weight: 3.0 oz". Wahoo's ELEMNT BOLT 3 (2025) Product Information page: "Weight: 3.4 oz // 84g". 84 g is about 3.0 oz, so the 3.4 oz figure looks like the odd one out, but Wahoo doesn't say.
- BOLT 3 in the box. The store page lists an out-front mount, USB-C cable, 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.
- Edge 550 battery wording. Garmin's spec table says "Up to 12 hours (demanding use)". The owner's manual specifications say "Up to 12 hours" with no condition. Both give up to 36 hours in battery saver mode.
What we could not confirm
- A like-for-like battery comparison. Garmin quotes "demanding use" and battery saver mode; Wahoo quotes a single "up to" figure with a usage caveat. Neither brand publishes a test method on these pages, so the hours aren't directly comparable.
- Edge 550 warranty. Not shown on Garmin's US product page.
- BOLT 3 and electronic shifting. Not mentioned on Wahoo's store or support page for the BOLT 3.
- Edge 550 mount bar size. Garmin lists a "Flush out-front mount" without a handlebar diameter.
- Out-the-door cost. Sales tax depends on your address; Wahoo showed "Fast delivery" with no shipping dollar figure.
