Why Choose iGPSPORT SPD70

This sensor solves a fundamental problem: getting accurate speed data to all your devices without complicated setup. The dual-mode Bluetooth/ANT+ transmission means you're not choosing between devices—your SPD70 broadcasts to everything simultaneously.

The 300-hour battery life is revolutionary. You install once, forget about it, and enjoy months of data without maintenance. The IPX7 waterproofing and anti-shock construction mean this sensor thrives in demanding conditions where lesser sensors fail.

At only 7.8 grams, it adds zero performance penalty while delivering professional-grade speed accuracy to your entire cycling ecosystem.

How It Works

Installation:

1. Mount the SPD70 on your wheel hub or crank arm
2. Pair via Bluetooth 5.0 or ANT+ with your device
3. Calibrate wheel circumference in your app/computer
4. Start recording accurate speed data

Data Transmission:
The SPD70 detects wheel rotations and broadcasts speed data in real-time to all paired devices. Whether you're using Garmin Edge, Wahoo ELEMNT, Zwift, or your smartphone, the sensor transmits simultaneously.

Battery Efficiency:
The low-power wireless protocol extends the CR2025 battery to an impressive 300 hours—over 12 days of continuous operation. In practical terms, expect 3–4 months of typical riding.

Dual-Mode Advantage

Why Bluetooth 5.0 AND ANT+?

Not all devices support the same protocol:

• Bluetooth 5.0: Smartphones, sports watches, fitness apps
• ANT+: Dedicated cycling computers (Garmin, Wahoo, iGPSPORT)

The SPD70's dual-mode design broadcasts to both simultaneously. Connect to your Garmin Edge AND your iPhone—both receive perfect speed data with zero conflicts.

Professional Accuracy

The high-sensitivity Hall-effect sensor measures wheel rotations with precision. Unlike GPS-based speed (which has inherent lag and inaccuracy at low speeds), the SPD70 provides real-time, accurate speed detection:

• Instant acceleration/deceleration detection
• Accurate cadence calculations
• Perfect for indoor training apps
• No GPS smoothing or averaging
• Consistent in all conditions (tunnels, urban canyons, etc.)

Weather & Environmental Performance

Built for Real Conditions:

• Rain and wet riding: IPX7 rated
• Mud and grit: Sealed design
• Temperature extremes: Durable polymer construction
• Salt spray (coastal): Corrosion-resistant materials
• High-speed wind: Minimal aerodynamic impact

Installation Options
