Finding the right cadence sensor helps you track RPM and pedal efficiency across outdoor and indoor cycling. The following five sensors are among the top options for Wahoo, Garmin, Magene, Sunny Health & Fitness, and CooSpo. This guide highlights what each sensor can measure, how it connects to apps and devices, and what to consider when choosing the best fit for your setup.
| Product | Brand | Key Feature |
|---|---|---|
| Wahoo RPM Cycling Cadence Sensor | Wahoo Fitness | ANT+ and Bluetooth, real-time cadence |
| Magene S3+ Cadence Sensor | Magene | Mode-switching, multi-device compatibility |
| Garmin Cadence Sensor 2 | Garmin | Bluetooth and ANT+ with self-calibration |
| Sunny Health & Fitness CB110S | Sunny Health & Fitness | Magnet-less design, Bluetooth connection |
| COOSPO Cadence & Speed Sensor | CooSpo | Dual-mode speed and cadence with ANT+ & Bluetooth |
The sensors listed here deliver cadence data (revolutions per minute) and, for some models, speed data as well. When pairing with apps like Zwift, Peloton Digital, Wahoo SYSTM, and Garmin Connect, these devices help you monitor your training load, cadence consistency, and endurance. Consider compatibility with your bike computer, phone, and preferred training apps, as well as battery life and magnet-free designs for easy setup.
Wahoo RPM Cadence Sensor For Indoor And Outdoor Bikes
The Wahoo RPM uses dual-band technology with ANT+ and Bluetooth Smart. It measures cadence and speed and connects to smartphones, tablets, and bike computers. Designed for compatibility with popular training apps like Zwift and Peloton Digital, it helps cyclists optimize cadence to ride more efficiently and extend endurance. The device is compact, easy to attach, and communicates real-time data for immediate adjustments during workouts.
Magene S3+ Outdoor/Indoor Cadence Sensor
The Magene S3+ supports Bluetooth and ANT+ with a focus on flexibility for multi-device use. Note that a single sensor mode is active at a time (speed or cadence), and a second sensor is needed to test both metrics. When using Bluetooth, it can connect to one app or device at once, while ANT+ allows multiple devices. This makes it suitable for riders who want precise cadence data across multiple displays or apps.
Garmin Cadence Sensor 2
The Cadence Sensor 2 attaches to any crank arm and measures pedal strokes per minute with Bluetooth and ANT+ connectivity. It self-calibrates with Garmin devices to ensure accurate cadence data and can send information to Garmin Connect and other training apps for indoor or outdoor rides. The sensor integrates well with Garmin ecosystems and offers reliable data sharing across devices.
Sunny Health & Fitness CB110S Cadence Sensor
The CB110S offers Bluetooth connectivity and a magnet-free design, simplifying installation. It tracks real-time metrics such as RPM and speed and pairs with the SunnyFit app for workout tracking, videos, and community features. The magnet-less design reduces setup complexity and debris interference, making it a practical option for many riders.
COOSPO Cadence & Speed Sensor
The COOSPO kit includes both a cadence sensor and a speed sensor, allowing simultaneous tracking of both metrics on compatible devices. It supports Bluetooth and ANT+ connections and can pair with multiple devices when using ANT+. The app connection requires locating sensors within the app, rather than relying on system Bluetooth listings, to ensure stable data transfer during workouts.
COOSPO Cadence and Speed Sensor (BK467)
This COOSPO option emphasizes both speed and cadence tracking with a dual-sensor package. It supports Bluetooth and ANT+ connections, enabling flexible data sharing across apps and devices. Like other COOSPO models, it requires app-level sensor discovery, which helps maintain reliable connectivity during rides across multiple platforms.
Garmin Cadence Sensor 2
The Cadence Sensor 2 by Garmin attaches to any crank arm and reliably measures cadence. With ANT+ and Bluetooth Low Energy, it can transmit cadence data to Garmin Connect and other apps, making it versatile for indoor and outdoor training. Its compatibility with multiple Garmin devices ensures easy data synchronization and long-term use within Garmin ecosystems.
Buying Guide: Key Purchase Considerations
- Connectivity: Choose between BLE, ANT+, or both. If you ride with multiple displays or apps, ANT+ can support multiple connections, while BLE offers broad compatibility with mobile devices.
- One-device vs. multi-device use: Some sensors allow only one app at a time over Bluetooth, while others support multiple devices via ANT+. Consider how you intend to train (one app at a time or simultaneous data across devices).
- Magnet-free designs: Magnetic sensors can require alignments and magnets near the crank. Magnet-free models simplify installation and reduce interference with bike components.
- Data scope: Decide if you need cadence alone or cadence plus speed. For trainers and bikes without built-in speed sensors, a combined sensor is beneficial.
- App ecosystem: If you use Garmin Connect, Zwift, Peloton, or Wahoo apps, verify compatibility and data export options to ensure seamless integration.
- Battery life and swap: Check battery type and expected life. Some sensors ship with pre-installed batteries and simple swap procedures for extended use.
- Ease of installation: Look for quick-attach designs and compatibility with most crank arms and hubs to ensure straightforward setup on indoor pedals and spin bikes.
- Calibration and accuracy: Self-calibrating sensors or devices with independent cadence algorithms typically offer more reliable data, especially for indoor workouts.
Overall, the best stationary bike cadence sensor depends on your current device ecosystem, preferred apps, and whether you also want speed data. For a simple, compatible option across many platforms, a dual-band cadence sensor with ANT+ and Bluetooth is often the most versatile choice. For Garmin users, a Cadence Sensor 2 offers deep ecosystem integration. For magnet-free setups and ease of use, Sunny Health & Fitness CB110S and COOSPO options provide straightforward installation and reliable cadence data.
