## Description

Product description Important Notice for Magene S3+ Users – Please Read Before Use To ensure the best performance and avoid common connection issues, we strongly recommend all users carefully review the operation guidance before first use. For the Magene S3+ Speed & Cadence Sensor , proper setup and activation are essential. Many connection problems are caused by incorrect installation, inactive sensor status, or improper pairing methods. B efore using the device, please make sure to Watch the operation video provided in the product listing images Read the updated Troubleshooting Manual available on this page Follow the correct steps for activation, mounting, and app connection We have recently added a detailed Connection Troubleshooting Manual to this page to help you quickly resolve any issues and get the best experience from your ride. If you still need assistance, our support team is always here to help. Ride smarter with Magene. Magene S3+ Sensor (Connection Troubleshooting Guide) To ensure a smooth experience with your Magene S3+ sensor, please carefully review the following key points. These tips address the most common reasons why the device may fail to connect. 1. Power-On Check: Make Sure the Sensor Is Properly Activated Review Instructions First: If you're experiencing connection issues, start by watching the operation video in the main listing image and reading the detailed user manual included in the product packaging. Remove the Battery Insulation Film: Before first use, ensure the insulation film on the battery has been completely removed. Secure the Battery Cover Properly: Rotate the battery cover clockwise until the white dot aligns with the lock mark. This ensures proper contact. Check for LED Indicator: Once powered, the sensor should flash a green or red light. If no light appears, the sensor is not powered on and cannot be connected. Lack of power is the most common cause of connection failure. 2. Wake-Up the Sensor: Ensure It’s Detectable Speed Mode: Spin the wheel to activate the sensor and allow it to be detected. Cadence Mode: Rotate the crank arm to trigger the sensor. If the sensor remains idle, it will stay in sleep mode and cannot be connected. The sensor must be awakened through movement before pairing. 3. Connect via App: Do Not Use Phone Bluetooth Directly Do NOT connect via your phone’s Bluetooth settings. Make sure your phone’s Bluetooth is turned on. Open a compatible cycling app (e.g., Magene, Wahoo, Zwift). Add the S3+ sensor within the app interface. Direct Bluetooth pairing from phone settings will not work. Magene S3+ Sensor Troubleshooting: For “Didn't pair to the device” complaints Step 1: Verify Operating Mode Remove the battery, wait 5 seconds, then reinstall (tighten cover to LOCK). Green flashing: Speed mode (mount on rear wheel spokes). Red flashing: Cadence mode (mount on left crank arm ). If indicator does not match intended use, repeat battery removal/reinstall. Step 2: Correct Mounting Position Speed mode: Secure to rear wheel spokes, sensor near hub, sensing area <5mm from rim/metal. Cadence mode: Attach to left crank arm exterior, ensure clear rotation path. After mounting, manually spin wheel/crank and check for data in app. Step 3: Wake-up and Battery Check Ensure plastic battery tab is removed. Sensor enters sleep after 1 minute inactivity; spin wheel/crank to wake. Replace with fresh CR2032 battery if unused for extended periods. Step 4: Connection Check Open app (Zwift, Garmin Connect, Magene Utility, etc.) and search for sensor (BLE & ANT+ supported). If not detected: Disable nearby Bluetooth devices → wake sensor → rescan. Test first with official Magene Utility app. Step 5: Further Assistance If unresolved, contact support with photos/video of LED and mounting setup.

Review: Inexpensive but work fine. - Bought to pair with my Garmin computer on my new mountain bike. Had some difficulty with installing the speed sensor on the rear hub because my hand couldn't reach in. Figured a way to do it though and it's installed. Cadence was a snap and both paid with Mt Garmin computer and appear to work fine.
Review: Impressive! - I use the Magene speed/cadence and Wahoo heart rate monitor with Cadence App. You can see the speed sensor literally taped to my Spinner front wheel. In the settings of Cadence you can adjust the wheel size for accuracy. I had a analog Cateye on my spin bike for years. The speed and cadence of the Magene sensors essentially mirrors what the Cateye readouts were. I will say the refresh rate is a little slow at times but very functional and accurate in my opinion. I like that there are no more wires on my bike and the functionality of using my phone for the monitor and storing the data from my workouts. If you choose to use Cadance App know this. When you add the sensors they will both show up side by side and you will think your done. You can select one sensor for each "add a sensor" so you must add them both again, select speed on one and cadance on the other and all is good. I find the Magene sensors to be a great value and I get accurate data on how I am performing in my workouts. In the images you will see the installation and the riding screen and the data output.

## Features

- [Battery] Remove the insulating sheet of the pre-installed battery before usage; re-install the battery to switch between the speed and cadence mode.
- [Mode] 1 sensor can ONLY select one mode (Speed or Cadence) at the one time.So you need 2 sensors to test both speed and cadence.(1 for speed,1 for cadence)
- [Device] When using the Bluetooth protocol 1 sensor can ONLY connect to 1 APP or device concurrently; When using ANT+ protocol it can be connected to multiple devices at the same time.
- [Connection] When using a smart phone APP, you need to search for the sensor in the APP, searching through the phone system’s Bluetooth setting is invalid.
- [Hibernation] S3+ sensor will automatically enter the sleep state for 1 minute to save power after the sensor is stationary, the sensor will ONLY start sending broadcasts after it is properly woken-up.

## Questions & Answers

**Q: I don’t have a bike computer can I use this with the iPhone/app only, no computer needed?**
A: Yes. You can use the Wahoo app. You don't even have to create an account with Wahoo.

**Q: Does this work for indoor cycling on a trainer, with connection to an iPhone, without a bike computer? I can’t seem to pair it with any apps so far**
A: Hello, please use "Magene Utility" app to get it connected, then use it with your indoor cycling app. It works with most of the popular apps. Please contact us directly if you need any further help.

**Q: will this record total count of spins per ride session, (not just per min)?**
A: It would seem the device is capable (it just counts...), but depends what your app/computer will report. My Wahoo element bolt only gives rpm........

**Q: Is this compatible with Magellan Cyclo 505 Bike Computer**
A: Yes it is, both Magene S3+ Sensor and Cycle 505 bike computer are ant+ compatible, they will work with each other.

### ⭐⭐⭐⭐ Cadence sensor did not work
*by T***Y on October 29, 2025*

One of the sensors did not work. I purchased the Magene c606 and was very excited to use the sensors. Speed sensor worked perfectly but unfortunately the cadence sensor never turned on and never synced with the computer. I’m looking for sensor from other company that will work with Magene. NEW UPDATE!!! Company reached out to me and sent me another sensor. I appreciate when companies puts in the effort to correct some issues.
