Review: Allows you to gather data on stationary bike - Got this for my stationary bike to be able to match to my coros watch. Works perfectly
Review: Worked fine on day 1 - compact - tidy - Was a little nervous after reading a few more negative reviews but after a 50 mile ride (dry) I’m happy with the connection and data to my head unit. Have used an additional cable tie and different bands to secure both cadence and speed sensor . Put the speed on the rear wheel hub and connection is continuous and stable ( I probably should have used front hub for a more direct signal though)

## 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: Will this work on a spin bike?**
A: Mine is a spin bike I have it on the hub

**Q: Does this work with the PlayStation vr vir game**
A: No

**Q: For Garmin, which metrics does it transmit in addition to speed and cadence? Does it provide distance? Thanks.**
A: Purchased for use on a bicycle/turbo trainer. The sensors transmit only speed/cadence. Connected to an iPad via Bluetooth, various apps calculate power and distance from the speed/cadence information. 

I would expect the same would be true for a Garmin app or device. 

Hope that helps

**Q: Can the cadence mode but used for an indoor bike by attaching to a shoe or inside the top of a sock?**
A: Yes it can be used this way but it's designed to be attached to the crank arm (I put it near the pedal on the left crank arm), this is how I use it on my indoor trainer.

### ⭐⭐⭐⭐⭐ Super sensors
*by E***L on 25 October 2021*

Required a couple of sensors for speed and cadence so I could use my classic turbo trainer with cycling apps. I went for the Magene S3+ in the end as they were small enough to fit my rear hub. Was a little concerned they wouldn't work properly or they'd be inaccurate but I had nothing to worry about. I've tried these on both Bluetooth and ANT+ and they work perfectly. No messing around just wake them up and your app will pick them up through the chosen connection. I installed the Magene app to manage the devices and set the mode cadence or speed. That was straight forward. They seem to have also been shipped with the latest firmware. I've tried these with Rouvy and they work. I haven't cross checked the accuracy of the sensors yet but my cadence and speed seem to be on par to my road cycling with similar effort. I've also connected them to Bkool with no issues. We'll see how long they last or if there's any issues with them but it's too soon to tell. So far I'm really happy with the sensors and would recommend these. If you're looking for well priced, small, magnetless sensors then you've found them. Great value.
