Meet the Magene S3 Plus Speed Cadence Sensor—a compact, dual-mode sensor engineered for serious cyclists who want precise data without clutter. Designed for ANT+ and Bluetooth LE, it pairs seamlessly with Wahoo devices, Zwift, and most cycling apps, turning your GPS bike computer or trainer into a data-driven training partner.

What makes Magene S3 Plus a cut above

The S3 Plus is a true dual-sensor powerhouse. It provides precise speed and cadence data in one small package, reducing the need for multiple gadgets on your bike. Built with a geomagnetic sensor, it delivers reliable rotation-based metrics even during heavy climbs or high-speed sprints, so your cadence patterns and speed trends are always accurate.

Key features that matter in real-world riding

• Dual-mode speed and cadence—one sensor, two critical data streams. Monitor your pedal tempo and how fast you’re moving, all from a single device.
• ANT+ and Bluetooth LE compatibility—easy pairing with Wahoo, Zwift, Garmin, smartphones, and cycling apps without extra adapters.
• Switch mode by re-seating the battery—a clever design twist: change between speed and cadence measurement simply by reinstalling the battery orientation. No more carrying or mounting separate sensors.
• Compact, lightweight build—8.85 x 29.8 x 38.3 mm and about 9 g with battery, minimizing drag and keeping your bike sleek.
• Reliable in a wide range of conditions—operating temperature from -20°C to 50°C ensures performance from winter rides to hot summer sessions.
• CE certified for quality and safety expectations on most markets.

Who should consider the Magene S3 Plus

Ideal for indoor cyclists using Zwift or other cycling apps who want a tidy, dependable sensor that covers both speed and cadence. Outdoor riders who want to validate cadence data across different training routes will appreciate the CONVENIENCE of a single sensor that toggles modes with a simple battery action. It’s also perfect for anyone upgrading from a single-mode sensor who desires a more complete picture of their pedaling efficiency and speed.

How this sensor fits into your training toolbox

– Indoor training: Pair with your trainer and Zwift to pace workouts with cadence-based intervals and speed-derived feedback.
– Outdoor rides: Track cadence to optimize pedal stroke, spin efficiency, and endurance under varying terrain.
– Structured workouts: Use cadence zones to target neuromuscular adaptations or aerobic development, while monitoring speed to gauge power output indirectly.

Practical tips for setup and use

• Ensure the battery is correctly oriented when switching modes to avoid incorrect readings.
• Pair once with your preferred device, then re-pairing is usually unnecessary for each ride—keep it simple and ride-ready.
• Keep sensors clean and free from excess sweat and dirt to extend battery life and sensor responsiveness.
• Use the same sensor across multiple bikes by swapping the mount or ensuring secure placement to maintain consistent readings.

What sets this apart from other options

Rather than juggling separate speed and cadence sensors, the Magene S3 Plus consolidates both measurements into a single, elegantly small unit. The battery-reseat switching method for mode changes is a distinctive, user-friendly approach you won’t find in every dual-sensor product. With broad compatibility and a geomagnetic sensing approach that supports stable cadence data, this sensor is a practical upgrade for riders who demand clarity in every pedal stroke and mph reading.

Experience a streamlined sensor that respects your bike’s aesthetics and your training rigor. The Magene S3 Plus is ready to pair with Wahoo, Zwift, and your preferred cycling apps—bringing precise, real-time speed and cadence data into your training story.
