Wahoo RPM Cycling Cadence Sensor
The Wahoo RPM sensor measures speed and cadence and connects via ANT+ and Bluetooth Smart. It works with compatible training apps including Wahoo SYSTM, RGT, Zwift, and Peloton Digital on iOS. The cadence metric reflects revolutions per minute to help optimize pedaling efficiency and endurance. Dual-band technology enables compatibility with a wide range of devices, from smartphones to bike computers, making it versatile for various home setups.
Magene S3+ Speed/Cadence Sensor
The Magene S3+ provides a dual-mode sensor capable of measuring speed or cadence, with options to pair via Bluetooth or ANT+. A pre-installed battery and mode-switch design require selecting either speed or cadence per sensor. It supports multiple devices when using ANT+ and is compatible with popular cycling apps and bike computers. Note that one sensor handles one mode at a time, so you may opt for separate sensors if you want both measurements simultaneously.
Garmin Bike Speed 2 & Cadence 2 Sensor
Garmin’s Speed 2 and Cadence 2 sensors attach to the wheel hub and crank arm, offering self-calibration with compatible Edge devices and Garmin interfaces. They provide live speed, distance, and cadence data through ANT+ and Bluetooth Low Energy, ensuring compatibility with many training apps and displays. The system emphasizes seamless integration with Garmin ecosystems while remaining broadly compatible with third-party platforms for real-time performance tracking.
MOOfit Speed/Cadence Sensor (2nd Gen)
MOOfit’s 2nd generation cadence sensor emphasizes reliable RPM tracking with improved sensors and geomagnetic components. It supports ANT+ and Bluetooth dual protocols, enabling connections to bike computers, apps, and wearables. The sensor suite is designed for compatibility with major cycling platforms such as Wahoo Fitness, Rouvy, CoospoRide, and Peloton, offering versatility across devices and ecosystems for cadence and speed data.
COOSPO Cadence And Speed Sensor
COOSPO’s RPM cadence sensor records real-time cadence or speed data on compatible bike computers or smartphone apps. It supports Bluetooth and ANT+ with limitations on concurrent connections depending on the protocol. The setup requires pairing through the app rather than system Bluetooth browsing, ensuring stable data transfer during workouts and easy integration with multiple training platforms.
Buying Guide
- Connectivity: Choose sensors supporting both ANT+ and Bluetooth to maximize device compatibility with bikes, displays, and apps you already use.
- Mode flexibility: Some sensors measure only speed or cadence at a time. If you want both metrics simultaneously, consider multi-sensor bundles or models explicitly designed for dual-mode use.
- Installation: Look for non-mre magnets or simple attachment to crank arms and wheel hubs. Easy installation reduces setup time and ensures consistent data.
- App ecosystem: If you ride with Zwift, Peloton, Rouvy, or Garmin Connect, verify compatibility and data transfer reliability with your preferred platform.
- Battery and maintenance: Check battery type, replacement intervals, and waterproof ratings (IP67 or better is common) for indoor environments and sweat exposure.
- Calibration and accuracy: Self-calibration features and ANT+ stability improve precision, particularly if you train with pace or cadence thresholds.
- App integration: Some sensors pair to multiple apps but restrict simultaneous connections. Plan your primary training app and ensure the sensor supports that workflow.
- Brand support and updates: Reputable brands tend to provide firmware updates and helpful customer support, aiding long-term reliability.
Additional Considerations
For home spin setups, consider whether you prefer a single device that covers both speed and cadence or a set of two dedicated sensors. Evaluate whether you will train with big platforms like Zwift or Peloton Digital, and whether you value hardware compatibility with Garmin devices or Wahoo ecosystems. Weather and gym-like environments at home may require IP-rated sensors for sweat resistance. Finally, confirm that your bike’s wheel hub and crank arm can physically accommodate the chosen sensor model.
