Review: It just works with Apple Fitness - The Magene speed/cadence sensor paired with my Apple Watch quickly and has been completely trouble-free. Once installed, I never have to think about it. When I start pedaling, it automatically connects and reports cadence in the Apple Fitness cycling app. It has been reliable, accurate, and easy to use. For anyone wanting cadence data without spending a lot of money, this has been an excellent addition to my bike.
Review: High quality cadence or speed sensor for the price - Easy to use, functional, and relatively inexpensive. I like that it can measure either cadence or speed simply by removing/replacing the battery. Clever design that doesn’t require a switch or app.

## 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.

### ⭐ Endless struggles with the battery cover and getting the red/green led to flash consistently.
*by A***K on January 26, 2026*

Sadly, I had no luck with this device ... and I never get as far as getting it installed on the bike. The older model had a notch extending out from the battery cover, making it relatively easy to slide the cover to then remove. This model has two indented notches pressed into the top of the battery cover so you'll have to use a coin or other similar tool to open the cover, not a major deal but super annoying when you end up having to fight with the cover repeatedly as I did. I struggled getting the battery cover to reseat properly into the unit, I tried seeing if there was a groove I needed to fit. The manual mentions to push the cover back on but that didn't work reliably for me. Perhaps most frustrating was the red/green light wasn't cycling as it was supposed to. This feature worked perfectly on my older sensor, take the cover off, take the battery out, put it back in, the LED flashes either red or green (depending upon what it was set to before). The light would not flash reliably on this model and more often then not it would flash red but was a struggle to get it to flash green. The frustration was magnified when it would finally flash green and then by the time I struggled to reseat the battery cover, the light would flash red again. I strugged with this for hours, wanting to believe it shouldn't be this difficult. Eventually I had to give up looking for consistency. One time, the unit finally flashed a green light and I was able to get the cover on...only for it to come off a short time later. I decided to return this. It's not worth the fight especially considering whenever the battery dies, I'd have to go through the same process all over again ... nope!
