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, Strava

Connected right away give good speed and cadence. Use or cadence on out door bike and speed on trainer

Why did you pick this product vs others?:Sensor is great, easy to install, easy to use, and made my workouts on spin bike that much better because I know if I am going hard enough now. Instead of watching the video and trying too match their speed I can see right where I am at. Functionality:Basically put it on the pedal crank, start the app, use the super cycle app to monitor the sensor, and away I go.

I have one Garmin 530 and 4 bikes. I have purchased a few of these. I have only used the speed function, not cadence. This is a cost effective way to add a speed sensor to multiple bikes. They pair easily with the Garmin. I have used them for a few months with no issues. The one issues is my Garmin sensors work fine from the rear tire, with these the rear tire is too far from the computer and it constantly disconnects and reconnects. Moving the sensor to the front tires has eliminated that issue. So they work fine for me but you have to use them on your front hub.

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

The Magene Sensor is a compact, lightweight device that switches between speed or cadence mode through a simple battery reinsertion. It’s compatible with Garmin app.Excellent Value: shipper than garmin sensor.Easy Installation and SetupAuto Calibration: Works with Garmin’s auto wheel-size calibration.

Works as it should!

I have two of these; one for cadence and one for speed/distance, on a commercial spinning bike. Installation was fairly straightforward, although the battery remove/reinstall to change it from speed to cadence is clumsy, and it times out pretty quickly, so be ready to link it when you reinstall the battery.Cadence went well - stays securely on the crank arm and reports reliably. Speed is another matter - at speeds over 25 mph, it's very inconsistent, bouncing between 10-12 mph and the 'real' speed, after calibrating it to actual wheel circumference. I chalk that up to the smaller wheel diameter on a spinning bike; that wheel is spinning much faster than a road or mountain bike at those speeds, and seems like the device can't keep up. I'll experiment with moving it from being attached to the hub to Velcro mounting it out further on the wheel so it's not inverting so quickly and see if that works.

Great sensors. Bought the 2 pack so I could add cadence and speed. Set up to my garmin.
