## Description

desertcart.com : Magene Outdoor/Indoor Speed/Cadence Sensor for Cycling, Wireless Bluetooth/Ant+ Bike Computer RPM Sensor for Road Bike or Spinning Bike and Trainers Compatible with Onelap, Wahoo Fitness, Zwift : Sports & Outdoors

Review: Seem like good value for the price - I bought these as an alternative to the big “G” and big “W” brands. Follow the included instructions to set them up, one as a cadence and one as a speed sensor. They paired easily with my Garmin 1050 head unit and seem to be a better design than the Wahoo pair that they replaced. So far they’ve worked flawlessly. I was impressed enough to buy a 2nd pair for my backup bike.
Review: No complaints - Does the job, easy install 🤔 overall and I'm a first time sensor user. Durable, rain, sleet snow, No complaints 🤷🏻‍♂️

## 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.

### ⭐ my sensor shows inaccurate cadence
*by N***I on June 4, 2022*

sensor is dissapointing. after i received it i connected it initiallly and a couple of days later when i actually went cycling, the sensor wouldn't connect so reseted it on the road and then it worked, that so far only happened once. the problem now though is that everytime i go cycling, i have not once received overall accurate reading with the sensor. to be precise, everyone once in a while the count would jump to 130+ and so on or drop completely and then it would do the same, but otherwise it would stay at or around the correct rate for some time but then it would mess up again temporarily, also in slight elevation it would just disappear for a short period, same as with some bumps but not all which i noticed last night. Because of the inaccurate numbers, my max cadence is way higher than it should be,i cant reach what it shows for even a second. i messaged the seller regarding this but no response at all, lucky for me i still have time to return it so i will just contact amazon in the next couple of days after i have found a replacement and return it. advice for anyone who wants to buy it, if you receive a good sensor, bless you, you got one for cheap, but if its bad or has issues, dont hold your breath for their reply. i understand now why their are some reviews regarding communication. my rating is for the accuracy -2* and drop in connection (elevation and bump -2*) of the sensor and not with the customer service at all, that would be lower
