Garmin Edge 840 Solar Review – The Ultimate Solar GPS Cycling Computer

If you’ve been waiting for a bike computer that offers longer battery life, the latest training tools, and next-level GPS accuracy, the Garmin Edge 840 Solar is exactly what cyclists have been asking for. Whether you’re a road cyclist, mountain biker, gravel racer, or weekend explorer, this device feels like a true upgrade from the previous Edge 830/820 and even a lightweight alternative to the Edge 1040.

The highlight of the 840 Solar is without doubt its Power Glass solar charging, which adds valuable extended battery life even during long rides. Garmin claims up to 32+ hours in demanding GPS mode and far more in battery saver mode — and in real-world riding, solar charging actually makes a significant difference. Riders who spend long hours outdoors, especially in Pakistan, UAE, USA and Australia, benefit a lot from this feature.

Touchscreen + Buttons – The Best Combination

Unlike previous models, Garmin now gives the Edge 840 both touchscreen and traditional buttons, making it far easier to use in rain, dust, mud or with gloves. The touchscreen is responsive and much improved over older Garmin units.

Multi-Band GNSS – Super Accurate GPS

This is where the Edge 840 truly shines. Its multi-band GNSS delivers extremely accurate tracking even in forests, mountains, tunnels and dense urban areas. Riders upgrading from older computers will immediately feel the difference on tight trails and rough terrains.

Advanced Training Metrics

For performance riders, the Edge 840 Solar offers features often reserved for pros:

• Training Readiness Score

• Stamina Tracking (real-time energy levels)

• Power Guide (plan power targets for climbs and segments)

• Recovery Time

• FTP Estimation

• Personalized workout suggestions

If you pair it with a heart rate monitor or power meter, the device delivers solid insights to help you ride smarter, not just harder.

ClimbPro – Now Better Than Ever

ClimbPro automatically detects climbs and shows gradient, distance remaining, and pacing.
It even works off-route, which is a big upgrade for MTB and gravel riders.

MTB Dynamics – A Treat for Mountain Bikers

The Edge 840 Solar includes Garmin’s MTB metrics:

• Jump distance

• Hang time

• Flow score

• Grit score

• Advanced off-road routing

If you ride on trails, this device gives fun and motivating data that no other cycling computer offers.

Navigation & Mapping

The Edge 840 Solar is packed with:

• Full Garmin Cycling Map

• Turn-by-turn instructions

• Forksight for trail systems

• Offline maps

• Route recalculation

• Popularity routing (heatmaps)

Navigation feels fast, accurate, and reliable.

Battery Life – A Major Win

Solar charging makes a huge difference.
If you ride 3–4 hours daily, you may go days without charging.

✔ Road cyclists
✔ MTB riders
✔ Gravel riders
✔ Bikepackers & touring cyclists
✔ Triathletes
✔ Riders upgrading from Edge 520/530/830
