Timing gates transform any trail segment into a timed run. Set virtual checkpoints along a course and the Edge 550 automatically records split times as you pass through each gate. Real-time split comparison shows whether you're ahead or behind previous attempts or target times. Post-ride analysis breaks down performance at each gate through Garmin Connect, identifying exactly where you gained or lost time across multiple runs.

Preloaded maps include worldwide MTB trail data from Trailforks. Forksight mode displays trail information at intersections: upcoming trail names, difficulty ratings, elevation profiles, distance remaining on current trail, and direction indicators. The computer routes rides specifically for road, gravel, or mountain biking using appropriate surface types for your activity. Trendline Popularity Routing overlays heat map data from billions of kilometers logged by Garmin Connect users, showing which routes experienced cyclists frequently travel in any given area.

Real-time weather overlays display radar imagery and wind direction on your route map when connected to a smartphone. Monitor approaching precipitation and wind patterns to make informed decisions about route changes or turnaround points. GroupRide features enable in-ride messaging with other participants, display live locations for everyone in the group, and show real-time leaderboards for climbs. You can compare your speed, cadence, and power output against the group average during the ride.

Road hazard alerts notify you about potholes, debris, and obstacles reported by other Garmin cyclists. You can contribute your own hazard reports to help the community. Incident detection uses accelerometer data to identify crash patterns, then automatically sends your location to emergency contacts when paired with a smartphone. LiveTrack shares your real-time location and ride metrics with designated contacts. The bike alarm emits an audible alert if the computer detects movement when you're away from the bike.

Battery performance reaches 12 hours with GPS tracking, map display, and sensor connections active. Battery saver mode extends runtime to 36 hours by reducing GPS sampling frequency and adjusting display brightness. WiFi connectivity enables automatic ride uploads to Garmin Connect when within range of known networks. The computer pairs with ANT+ and Bluetooth Smart sensors including power meters, heart rate monitors, cadence sensors, and electronic shifting systems from Shimano Di2 and SRAM AXS. Integration with eBikes displays motor battery status and assist level. Connection to Varia radar and lights provides vehicle approach warnings and allows lighting control from the computer display.
