Wahoo RPM SPEED Sensor

I've been using the Wahoo RPM Speed and Cadence Sensors for a while now, and they’ve been awesome. They’re super easy to set up — no magnets or complicated installs. The cadence sensor sticks right on your crank or shoe, and the speed sensor goes on the hub of your wheel. Took me about 5 minutes to get them both going. They pair instantly with my phone and bike computer using Bluetooth or ANT+. I use them with Strava and the Wahoo app, and the data is very accurate. Cadence readings are smooth, and speed is more reliable than GPS, especially indoors. Battery life is great — I’ve been using them for months and haven’t had to change the battery yet. Plus, they’re waterproof and still work perfectly after a few rainy rides. If you want simple, no-fuss sensors that just work, I totally recommend these. They’ve made tracking my rides way more fun and consistent.

I've been using Runmeter on my iPhone to track my rides. However, while using GPS for pace is fine for running, it's not so good for tracking speed, as GPS has a natural delay and doesn't update as frequently as needed to give a truly accurate speed reading. Having a dedicated sensor solves that problem. What attracted me to this was how there is no magnet. For those who aren't aware, traditional speed sensors require placing a small magnet onto a spoke, and then mounting a sensor to the frame. You had to get them just right, too, particularly with keeping a small a gap as possible between the magnet and the sensor. Plus, I was never fully confident the speed was very accurate since the calibration is done using your wheel diameter and the magnet/sensor might anywhere within that radius. These sensors use a gyroscope to sense actual motion. The speed sensor goes onto the hub of a wheel with a rubber band, which is quite beefy and holds tight. It's that simple! The cadence sensor was just as easy -- use the included zip ties to secure it to the inside of the left crank arm, and done! I have no worries that either will fall off. Pairing them with my iPhone 6 Plus was perfectly easy, too. I had to wait for one to go to sleep before I could pair the second one, but that wasn't so bad and I had no problems at all. I've read other reviews where people said they wouldn't pair or stay connected, but I wonder how much of those were due to personal savviness and rather than the product itself. For me, everything worked perfectly during setup. I've been on several 30+ mile trips since the sensors were installed and I haven't had a lick of trouble. Speaking of Bluetooth, I must say that I haven't really noticed any reduction in battery life on my iPhone after putting these into use. I'm sure it does take a little extra juice for my phone to use them, but the difference has been imperceivable (which is to be expected from any Bluetooth Low Energy device). They'll emit a quick blue blink once every couple of seconds so that you'll know whether they're on. But it's not excessive and you won't even see it while you're riding. The only time I've noticed it is when walking my bike in and out of my apartment. Note that you're not restricted to using the app provided by Wahoo to track your speed and cadence. Most of the well-known fitness apps include functionality for using external sensors, you just have to make the app aware that you have them, and they'll use them. There's only one complaint, and it's trivial. When I pulled these out of the box, they were already blinking at me. The means that at any point during shipment where there was motion, they were on, wasting the battery away. So, the cadence sensor is already at 50% on the first day. I don't know if they came from the factory without a battery insulator, of if perhaps mine was a returned set where the insulators had already been pulled out (but mine seemed brand-new). Whatever, it's okay -- they're replaceable and certainly has no bearing on the quality of the sensors themselves. The batteries are supposed to last a year or two, so it's fine. Wahoo seems to be the leading innovator in Bluetooth and ANT+ sensors intended to be used by third-party apps. These are working beautifully for me, and so were worth every penny!

Using on stationary cycle. Works great to record workouts and share with other fitness platforms.

I'll admit, not so shamefully, that I am a bike snob. I am also a user of both Wahoo and Garmin which I believe allows me to give a great comparative opinion. My primary bike, which is a carbon frame Cervelo, has the latest generation and very easy to install Garmin sensors. My secondary bike is a clunker aluminum road bike has these Wahoo speed and cadence sensors. The reason I have them on my secondary bike is because I use that one on an indoor trainer and want to connect to my iPad for Trainer Road using the Bluetooth feature found in Wahoo sensors. It appears that no Garmin devices use Bluetooth, even the latest generation. I previously had the older generation Garmin speed and cadence sensors on my secondary bike which are ANT only and needed a USB dongle to connect to trainer apps, confining me to my computer for Trainer Road. I did not want my laptop occupied while I was on the trainer so that others in the household can use it during such time. Additionally, Bluetooth seems to play better with the indoor training apps than an ANT USB dongle, at least in my experience. I do use my secondary bike outdoors, but not for racing or high speed club rides, so I don't need 100% perfection for outdoor readings when using my secondary bike since it's my errand runner/commuter/backup road bike. Overall these sensors are pretty solid. My Garmin Edge 500 will pick them up, and they are ideal if you want to use an iPad, iPhone or other bluetooth device for Trainer Road, Zwift, etc. You can also use Bluetooth and ANT at the same time to get readings on both your trainer app and ANT head unit. The physical installation was fairly easy, significantly more so than the previous generation of speed and cadence sensors. I will notice the readings are not perfectly stable 100% of the time, but it's certainly no hindrance. One thing to note, is that it is recommended you download the Wahoo Utility app on your phone to make sure these devices have the latest firmware, in addition to making sure your Garmin head unit has the latest firmware. This could be why other reviewers complain that the sensors discontinue working after a certain period of time. The final verdict is that these Wahoo speed and cadence sensors are a good product, better than other speed and cadence sensors, but not better than Garmin. For what I use them for, secondary bike/indoor trainer, they serve their purpose well. I choose them specifically for the Bluetooth connectivity which is an excellent feature. Depending on what you do, whether it's leisure riding, moderate to fast club training rides, or even racing, and your level of acceptable data error/reading dropout from your head unit, they should work just fine. These are second place in terms of brand to Garmin for bike sensors. They are pretty good, but being a user of both, I will say Garmin is definitely better and I very much prefer Garmin on my primary bike which gets the most use, especially outdoors. If you have one bike and do not use trainer apps where you need Bluetooth connectivity, go with the Garmin sensors. Just my opinion, but either way you can't really go wrong.

I’m an old man who still needs to exercise. I have used these on my outdoor bike with an indoor bike trainer to keep me from slacking off. Since being retired I find slacking off is much easier than it used to be. So far they have worked flawlessly and connect seamlessly to the free app that works on android or IPhone or tablets. I set mini goals like increasing my average speed or cadence daily by a small amount. I listen to a book on tape (on my phone) while tracking my speed and cadence on my tablet It makes that daily exercise routine something I almost look forward to. Feel better, not much improvement in my looks however😀. Beats the old magnet type Speedo’s and is a great value IMO.

Does the job

The wahoo sensors are very easy to fit, not using magnets (and offering Bluetooth and Garmin signal protocols) they are accurate over the ride - best ones I’ve used and having cycled for years I’ve used a lot. Two downsides and another upside - they can be a little fiddly to set up with whatever riding software you are using but the staff on the support desk are absolutely top rate and very customer focused. The only real downside is that the Wahoo software only uses chest worn heart rate sensor whilst cyclemeter is already linked to my Apple Watch -brilliant c,mon Wahoo get talking to Apple and get this feature added, you will have a world better solution then

I paired these with the Wahoo app instead of buying a bike computer and it works great. Just need to set Wahoo app to run in background on your phone and it provides continuous logging. Sadly, Fitbit is not compatible with these sensors so I can't combine all the data onto 1 platform. So you are forced to choose which Health platform to be on.

Sono rimasto sorprendentemente soddisfatto di questi due sensori montati sulla mia bici da strada. Devo dire che Wahoo sta facendo passi enormi verso la tecnologia da strada al punto che anche il ciclocomputer ho cambiato e passando alla stessa medesima marca. Funziona tutto alla perfezione e i dati che raccolgo ad ogni uscita sono precisi. Per chi è amante della prestazione, dei dati analitici da mettere a confronto ad ogni uscita, wahoo fa del vostro caso! Consigliatissimo. Confezione ben preparata oltre che la perfezione nel servizio della consegna!!

To keep track of my exercising regime.
