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

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.

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

This cadence/speed meter is super easy to setup and connect to bike computer, provides consistent data, looks sleek, and does what it says it will perfectly. Great price, only reason I’m leaving 4 stars is because my first one fell off during a ride, not sure if it was due to an error I made installing or due to a High RPM sprint while riding, but for the price I wasn’t punching the air when I noticed it fell off.

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

Fabulous product. Easy breezy connection to my Wahoo. 1/2 price vs Wahoo sensor.

Comes with battery installed but you must remove the hard-to-see clear plastic battery insulator that is in place on one side of the battery. You must remove the battery from the screw-on cover to remove the insulator.The only application that I found that I liked is Wahoo. The others all seems to be subscription services, some being VERY expensive and having whole visual environments to ride your stationary bike through. Bluetooth connectivity and general setup was quick and easy.

Received these on Wednesday. Installed on Wednesday and did short test and both seemed to work properly. Went for a ride on Thursday and one unit didn't want to work. I checked my installation figuring maybe I made a mistake. Went for a ride on Friday and the first unit still did not work and the second unit failed during the ride. Brought both units inside and checked the batteries. Both read well below 3 volts. I replaced both. Reinstalled both units. One unit would not work in cadence mode but works well for speed sensing. Obviously I was aware of this because I wanted it for cadence so I removed both sensors and swapped them and reinstalled. After a short bench test both seemed to have found a home and my ride on Saturday was a real pleasure with both operational. The batteries had shipped with a plastic disk between the battery and the contacts in the units. The instruction suggest they should be good for 500H of use. Apparently these had been on the shelf somewhere too long. In addition, there may have been some form of leakage that caused the one unit not to be able to do the cadence function. In both units the red light is quite bright while the green is invisible in sunlight. The failing unit was a little less bright green suggesting that it has a problem somewhere.

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.
