Garmin Edge 1040 GPS Bike Computer Unit Only – Advanced Cycling Navigation & Performance Tracking

The Garmin Edge 1040 is Garmin's large-screen flagship cycling computer, stepping up from the Edge 840 and Edge 850 with a bigger display, a class-leading 35-hour GPS battery life (up to 70 hours in battery saver mode), and the full suite of Garmin's advanced performance analytics. Available here as Unit Only — computer and mount included, sensors sold separately.

Navigation is built on multi-band GNSS technology for exceptional positional accuracy in dense woodland, urban environments, and remote terrain where standard GPS units struggle. Ride type-specific maps highlight popular roads, trails, and searchable points of interest, and the device integrates directly with Strava, Komoot, and TrainingPeaks® via the Garmin Connect™ app for seamless route planning and post-ride analysis. The ClimbPro ascent planner gives you gradient profiles, remaining ascent, and real-time effort data on every climb — essential for pacing on long or mountainous routes.

On the training side, the Edge 1040 analyses your strengths and weaknesses over time, delivering power target recommendations, stamina insights, and adaptive workout suggestions that adjust to your current fitness and recovery. Missed a session? The device prompts you to reschedule and stay on track. When paired with a compatible power meter and heart rate monitor, you unlock the full depth of Garmin's coaching ecosystem. Browse the full Garmin range, our computers and GPS collection, or explore compatible power meters and heart rate monitors to get the most from the Edge 1040.

With 35 hours of active GPS battery life, the Edge 1040 is the natural choice for ultra-endurance events, multi-day tours, and any ride where battery anxiety is simply not an option. This listing is for the Unit Only — mount and computer included, sensors sold separately.

Frequently Asked Questions

How does the Edge 1040 compare to the Edge 850?
The Edge 1040 offers a larger display and significantly longer battery life (35 hours vs the Edge 850's 24 hours in GPS mode), making it the better choice for ultra-endurance events and multi-day tours. Both share Garmin's core analytics suite, but the 1040's screen size and battery capacity are its primary advantages.

What is included in the Unit Only package?
The Unit Only includes the Edge 1040 computer and a handlebar mount. Sensors such as speed, cadence, heart rate monitors, and power meters are sold separately. Browse our power meters and heart rate monitors for compatible options.

How long does the battery last?
Up to 35 hours in standard GPS mode, and up to 70 hours in battery saver mode. This makes the Edge 1040 one of the longest-lasting cycling computers in Garmin's lineup, suitable for full-day sportives, ultra-endurance events, and multi-stage tours.

Can I customise the data fields on the Edge 1040?
Yes — data fields are fully customisable either directly on the device or via your paired smartphone through the Garmin Connect™ app, allowing you to display exactly the metrics most relevant to your training and riding style.
