RPM Cycling Speed/Cadence 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.

These sensors are almost identical to the form factor of a Garmin foot pod, they use the samr CR2032 battery format but the opening process is different. There is no power button, they wake up when moved and a blue LED flashes. I was able to pair these two sensors to my Garmin Forerunner 235 in just seconds. Installing both sensors with 3M VHB tape also took seconds. There is no further setting for the cadence sensor, it just worked. For the speed sensor I had to go into the Garmin and turn off the auto-wheel size and enter a value by hand. It does not explain that the value is the circumference of the wheel, so I just guesstimated it by comparing the speed on the bike's computer against the Garmin, that got me within 1/10th of a mile per hour. Later, out of curiosity I measured the wheel by hand and noticed that the circumference was almost identical to what I had guesstimated, I was off by 7 mm. So yes, if you have a Cyclace spinning bike (https://www.amazon.com/gp/product/B07PMD1WG8/) your wheel circumference is 1,357 mm. I was able to get on the bike and track a session immediately, Garmin Connect correctly tracked speed and cadence, and the activity was automatically pushed to Strava instantly. Mission accomplished. I will update this review once I have had a chance to put a few hundred miles into these sensors, but so far I am very pleased. Downsides: None, unless you are a Fitbit user. This is not Wahoo's fault, it just annoys me that my wife can't take advantage of these sensors for as long as she uses a Fitbit, and she refuses to switch to Garmin.

I purchased both speed & cadence at $60 others same day delivery. Delivery was made late at night and to my next door neighbors house....I intercepted and retrieved. The Wahoo sensors installed very easily onto my Star Trac NXT Spinner with the solid wheel. I know, Wahoo says you can’t install onto a spin bike but you can (see photos). Once installed (both Cadence & Speed took less than a minute to install) pairing and displaying in the Wahoo Fitness App was flawless. When setting up the Speed sensor the app will ask for wheel diameter, I entered 1.54 meters (I measured wheel diameter with a soft tape measure) in the “Custom” box. I got on my spinner and started pedaling, readout on the Wahoo Fitness App showed that I was going 16 mph and pedaling at 67 RPM. It displayed all workout info on my iPad mini 4 (I’ll try Android next & update ya’ll). I also fired up my free for 7 day trial of Zwift, in less than a minute I was riding in Italy with a pack of riders. Grant it you don’t really have a power output for a given resistance but if you can judge pretty closely the real life feel of the resistance you apply to the spin wheel the Zwift app is pretty realistic cycling game/workout. I’m very pleased with my setup and the Wahoo Speed & Cadence sensors.

I reviewed this product along with others to match with my stationary bike & holofit. The ratings for it was good & according to the web it matches very well with Holofit. I have used it twice already and it seams to slowdown at times & even stops working for a brief second before it continues. It has nothing to do with my pedal speed for it is more or less the same. Nor my internet speed, I work from home & have very good internet & wifi. I still get my workout in, but the constant pauses, does throw my workout off.
