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

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.

Love this for the price. No problems syncing with my Garmin. Accuracy seems good enough. Very small, tucks easily away on the back side of the crank arm. The bands that hold it on are generic enough that you could find a replacement at a hardware store or just zip tie it on if necessary. It has two modes so make sure you select the correct one when installing it. Red blink means cadence and green means speed. Change the modes by removing and reinstalling the battery. Red and green blink means the battery needs replacing. I had both modes show up while pairing over ant+, so make sure you choose the right one. Don’t forget to remove the transparent plastic disc between the battery and the sensor when you first get it. The battery cover tool is a nice addition that I noticed after I pulled the battery off easily by hand.

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!

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.

I am in love with this cadence sensor. It was easy to install on my stationary bike. The directions were clear and easy to read. I use it to connect my bike to my VR headset. It changed the whole stationary bike riding game for me.

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 bought this to replace my non-working Garmin speed sensor. I wasn't sure this inexpensive unit would even connect to my Garmin watch, but I was surprised. This unit connected immediately to my watch and has all the functionality my Garmin sensor had. The best part is it is a fraction of the cost and well worth the purchase.

Arrives fast and works but there are several issues. Battery cover is cheap plastic and the tab tore off on one of my sensors. It still works but hard to remove battery cover now and it is no longer waterproof. I bought two of these and they both work for speed or cadence but my iPhone will only connect to one sensor or the other. I would like to have both speed and cadence and have been able to do this with other sensors but not these. One of my batteries went bad in a few weeks. I am not sure if this was a battery issue or if the device didn't sleep. The rubber bands are fairly thin and I am not sure if they will last.

Fait le boulot ! Pas trop cher et précis !

Instalei na bike de spinning, funcionou bem fixando perto do eixo, na roda não mediu direito. Usei abraçadeira de velcro e fixou perfeito, minha bike tem uma roda de 19kg. Já a entrega, comprei o produto que não informava que se tratava de uma compra internacional, Amazon deveria cuidar melhor disso, eu não teria comprado desse vendedor se tivesse a informação de compra do exterior.

Excellent accuracy. Sync this to wahoo fitness app easily.

El objetivo era tener controlado un poco más el entrenamiento en ciclismo a falta de un potenciómetro. Su instalación fue sencilla el manual pues indica cómo poderlo usar en mi caso era para la detección de la cadencia lo cual lo instalé en una biela. Y lo conecté a un reloj garmin y sin problema vía a ANT+. En cuanto a las mediciones de cadencia se ajustan mucho a la sensación a la que uno va sin problema recomendable para el uso de entrenamiento.

It is important to remember that first power application puts it into speed sensor mode and you need to remove the battery and reinstall it a second time to put it into cadence sensor mode. The supplied tool is handy for this.
