The unit pairs with your phone and third‑party services so you can review routes, synchronize workouts, and monitor speed, cadence, heart rate, power and altitude without running cables across your handlebar.

How accurate is the GPS tracking and what satellite systems does it use?

This device uses a multi‑GNSS chip that locks to GPS, GLONASS, BDS and Galileo for faster fixes and improved accuracy across different regions. The imported navigating chip improves sensitivity in tree cover and urban canyons, helping keep your recorded route truer to reality.

• Four satellite systems for broader coverage and faster positioning.
• High‑sensitivity chip to reduce signal dropouts.
• Route synchronization to phone app for post‑ride review.

Which sensors and apps can it connect to for training data?

The computer supports ANT+ sensors and Bluetooth connections so it can display and record speed, cadence, heart rate, power and elevation concurrently. You can pair the unit with the companion app and link to services like Strava to export ride files or follow training metrics over time.

• ANT+ for heart rate, cadence and power meters.
• Bluetooth pairing with your smartphone for route sync and notifications.
• App integration enables data export to platforms such as Strava.

What is the screen like and how readable is it in different lighting?

The 2.9‑inch FSTN LCD is designed to stay readable in bright sunlight and low light thanks to a glare‑reducing layered panel and automatic backlight adjustment. Tempered glass protects the display from scratches while the brightness adapts using local sunrise/sunset settings so information remains visible throughout the day.

• 2.9" FSTN display for high contrast and low glare.
• Auto brightness based on local time zones for day/night visibility.
• Durable tempered glass resists scratches on long rides.

How durable is it and what is the battery performance?

The unit is built to handle wet weather with IPX6 water resistance and a wireless setup that keeps cables off the handlebars. A 1200mAh battery plus fast‑charge circuitry delivers over 60 hours of runtime and recharges fully in roughly three hours, making it suitable for multi‑day tours or long training sessions.

• IPX6 rating to withstand heavy rain and splashes.
• 1200mAh battery with fast‑charging for ~3‑hour full charge.
• Over 60 hours of typical operation per full charge.
