Garmin Wireless Speed Sensor 2 & Cadence Sensor 2 Bundle
Garmin’s Wireless Speed Sensor 2 and Cadence Sensor 2 bundle offers a complete, magnetless setup for both speed and cadence data. The speed sensor attaches to the wheel hub and self-calibrates with your Edge cycling computer or a compatible Garmin device to deliver accurate speed and distance data, even when a head unit isn’t present. The cadence sensor attaches to any crank arm and measures pedal strokes per minute to optimize training. Both sensors support ANT+ and Bluetooth Low Energy, enabling live data streaming to training apps and displays.
The sensors pair with Garmin devices and many third‑party platforms, permitting data transfer to Garmin Connect, Zwift, Strava, Peloton, and other training apps. With the bundle, riders can monitor speed, distance, and cadence in real time and adjust workouts based on immediate feedback.
Garmin Speed Sensor 2 & Cadence Sensor 2 Bundle
Garmin’s Speed Sensor 2 and Cadence Sensor 2 bundle emphasizes easy, magnetless installation. The speed sensor mounts on the wheel hub and self-calibrates with your Edge or compatible Garmin device, delivering reliable speed and distance data whether or not a head unit is present. The cadence sensor attaches to the crank arm and measures pedal revolutions per minute to support cadence-centered training. Both sensors communicate via ANT+ and BLE, enabling data transmission to Garmin devices and compatible apps.
These sensors offer magnetless installation and simple transfer between bikes, with no alignment required. They self-calibrate with Garmin devices to ensure consistent speed and distance readings, while ANT+ and BLE keep data flowing to compatible apps and displays.
Magene S3+ Speed/Cadence Sensor
Magene S3+ is positioned as a versatile speed and cadence sensor for indoor and outdoor cycling. It supports Bluetooth and ANT+ connectivity, so you can pair with most bike computers, phones, or apps. Note that a single sensor can be configured for either speed or cadence at a time, so most riders will run two sensors to monitor both metrics. When using Bluetooth, a single sensor connects to one app or device concurrently; with ANT+, it can broadcast to multiple receivers.
Designed for flexible setups, the S3+ pairs easily with popular platforms like Zwift or other training apps via BLE or ANT+. The device’s lightweight form and robust wireless options make it a practical choice for mixed riding environments, including indoor trainers and outdoor routes.
Wahoo RPM Cadence Sensor
Wahoo’s RPM Cadence Sensor provides real-time cadence data with a compact form factor and straightforward mounting. It measures revolutions per minute and delivers data to compatible apps and devices, including Zwift, Peloton Digital, and Wahoo’s own ecosystem. The sensor uses dual-band technology (ANT+ and Bluetooth Smart), enabling connections to smartphones, tablets, and bike computers. Its portability and ease of transfer between bikes support quick setups for group rides or multiple bikes at home or in a gym.
Designed for reliability, the RPM Cadence Sensor integrates with Wahoo’s ecosystem and many third‑party apps to support cadence‑driven workouts and performance tracking. Whether your rides are outdoor routes or indoor intervals, this sensor offers dependable cadence data across platforms.
iGPSPORT Speed Cadence Sensor
iGPSPORT’s Bike Speed Cadence Sensor delivers precise speed and cadence measurements using independent algorithms designed for accuracy. It supports Bluetooth 5.0 and ANT+ so it can connect to a wide range of bike computers, smart devices, and apps. The sensor offers long battery life and a lightweight design, making it suitable for riders who frequently switch bikes or rides that include multiple training devices.
With up to 300 hours of battery life, this sensor provides dependable performance for extended training cycles. Its broad compatibility with major brands and platforms makes it a versatile option for riders seeking a budget-friendly yet capable speed and cadence sensor solution.
Buying Guide
- Compatibility and connectivity: Confirm whether your bike computer, phone, or tablet supports ANT+, Bluetooth, or both. If you use multiple ecosystems (Garmin, Wahoo, Zwift, Peloton), choose sensors that can broadcast to several platforms simultaneously or pair easily with your preferred apps.
- Single sensor vs. dual sensors: Some options (like Magene S3+) require two sensors to cover both speed and cadence. If you need both metrics on multiple devices, a bundled or dual-sensor setup may be worth the investment.
- Installation and portability: Magnetless installations simplify mounting and moving sensors between bikes. Consider how quickly you can swap sensors and whether you need to mount on different wheel hubs or crank arms.
- Battery life: Longer battery life means fewer interruptions during training. Look for sensors with user‑replaceable batteries or rechargeable options that suit your riding schedule.
- App integration and data quality: Check how well each sensor integrates with your apps (Garmin Connect, Zwift, Strava, Peloton, etc.) and whether data is updated in real time with minimal latency.
- Water resistance and durability: Riding in variable weather or sweaty conditions benefits from IP ratings or robust build quality to withstand moisture and dust.
- Budget and value: If you ride across multiple setups, a magnetless, easy-to-transfer bundle can reduce friction and provide better long‑term value.
- Future expandability: If you plan to upgrade devices or add more sensors, consider ecosystems that allow seamless data sharing across platforms without extra hardware.
- Calibration and accuracy: Look for sensors with automatic or straightforward calibration routines to maintain accurate speed and cadence readings over time.
