Wahoo Speed and Cadence Sensor Review
Wahoo Speed and Cadence Sensor Review
Based on my experience, it’s difficult to go wrong with Wahoo’s Speed and Cadence Sensors, which are competitively priced, easy to set up and use, extraordinarily durable, and use limited battery power. However, the metrics reported by Wahoo’s app (e.g., speed, mileage, etc.) often differ from other popular tracking apps like Strava — sometimes by a meaningful amount.
Wahoo’s app frequently
- Although not necessarily effortless, setup is easy and straightforward
- Work with a wide variety of platforms
- Long battery life, for both the sensors, as well as the app’s drain on your smartphone
- Quality construction and durability
- Competitively priced
- Manufactured by a company with solid reputation among cyclists
- Wahoo’s app doesn’t seem to track data as accurately as other popular apps, like Strava
User Review( vote)
I purchased Wahoo’s Speed (04FE) and Cadence (4931) sensors to use with a Saris M2 Smart Trainer, along with Zwift. After a few weeks of testing, here’s what I’ve learned.
Updated May 2, 2020
How Does the Wahoo Speed and Cadence Sensor Work?
Wahoo Speed and Cadence sensors universally attach without magnets, wirelessly integrate with Bluetooth and ANT+ compatible accessories, and track cycling speed and cadence in real-time.
Each lightweight sensor weighs just 7 grams, measures 1.2 x 1 x 0.8 inches, boasts IPX7 waterproof specifications (up to 5 feet), and includes replaceable CR 2032 batteries that can last up to 12 months.
Wahoo Speed and Cadence Sensor Compatibility
Wahoo’s RPM Speed and Cadence sensors connect to any app or fitness product that broadcasts over standard Bluetooth or ANT+ protocols.
This way, you can upload their data to a wide variety of training, tracking, visualization, and mapping apps like Strava, MapMyRide, Zwift, TrainingPeaks, Runkeeper, RideWithGPS, and Apple Health and Google Fit, to name just a few. Hardware compatibility is similarly broad, including a wide variety of bike computers, heart rate monitors, and power sensors, as well as Apple Watch.
In the rare event that Wahoo’s Speed and Cadence Sensors don’t automatically transmit their data, you can export .fit files and upload them to the platform of your choice.
Installing & Setting Up Wahoo’s Speed & Cadence Sensors
Installing and setting up Wahoo’s Speed and Cadence sensors is a relatively straightforward affair.
First, you’ll insert each sensor into their respective sleeves, making sure that the Wahoo logo faces outward.
Next, you’ll place the Speed sensor’s rigid plastic mount onto your front or rear hub, gently stretch the rubber strap, and then secure it to the two bottom hooks on the mount’s opposite side.
In my experience, this part of the process requires the most trial and error. The strap fits tightly and requires some finagling to maneuver fingers between spokes and my hub while also rotating my wheel enough to latch the rubber strap into the other side, but not so much that I lose tension against the hub.
Comparatively, Wahoo’s Cadence sensor attaches to the inside of your non-drive crank arm using double-sided 3M tape. Wahoo includes two zip-ties for more secure mounting.
I chose to use the shoe clip since I didn’t want to attach anything else to my bike—at least for the time being.
Using Speed & Cadence Sensors With Wahoo’s Fitness App
Once you’ve installed your Speed and Cadence sensors, you can connect them to Wahoo’s Fitness app (or a third-party app or device) to track cycling, running, or cardio workouts via GPS and Bluetooth.
Pairing the sensors is super easy, and the app quickly recognizes them. The exterior LEDs also flash according to their connection status (e.g., slow blink = awake but not paired, quick blink = connected, etc.).
Inside the app, Wahoo provides access to your workout history, personalized calorie burn count and heart rate zone information, comprehensive power data (as long as you have a power sensor installed), and customizable audio alerts.
If you own a KICKR smart trainer, the Wahoo Fitness app delivers four dedicated modes, including Resistance Levels, Erg, Simulation, and Manual.

Once paired, any movement will “wake up” your Speed and Cadence sensors, although their LED notifications only last about 30 seconds to help maximize battery life.
Along these same lines, I’ve found that the Wahoo app doesn’t drain my smartphone’s battery, even with it, Ride With GPS, Strava, and Pandora running in the background. I do, however, put my phone in low power mode before heading out.
From an accuracy perspective, I’ve noticed some small discrepancies between data recorded in the Wahoo app and data from third-party apps like Strava.
I don’t currently
have a heart rate monitor connected, although this is something I plan to add
Finally, Speed and Cadence sensor updates are downloaded via the Wahoo app. You’ll automatically receive a prompt when they’re available, and you can choose to download immediately or wait until later.
Wahoo RPM vs. Other Speed and Cadence Sensors
Several speed and cadence sensors are competing with Wahoo’s, most of which feature wireless functionality, magnet-less attachment, compatibility with most Bluetooth and ANT+ enabled software and gear, universal fit, and replaceable batteries.
Here are some of the top options listed on Amazon:
Choosing between these isn’t rocket science, and will largely depend on which factors you find most important.
For example, if the price is your top consideration, OUTERDO’s Speed and Cadence sensor cost less than half that of the next-closest option, Wahoo’s BlueSC.
As a standalone sensor, though, OUTERDO might not capture data as accurately as systems that include two sensors. Furthermore, several third-party overseas companies offer very similar models, without apparent differences between them.
At the other end of the spectrum, Garmin’s Speed and Cadence 2 sensors cost the most by a fairly wide margin. However, like Wahoo, Garmin supports its sensors with a standalone fitness app, if this aspect is important to you.
With these details in mind, let’s wrap up.
What’s the Bottom Line About Wahoo RPM Speed and Cadence Sensors?
In my opinion, there’s a lot to like about Wahoo’s Speed and Cadence Sensors: they’re competitively priced, come from a reputable company, feature mostly positive online customer feedback, and I’ve found they’re easy to set up and use via the company’s proprietary app.
They also work well with our Saris M2 smart trainer, in conjunction with the Zwift app.
So far, the only nitpick I have is that there are minor discrepancies between the data collected by Strava, versus data collected by the RPM Speed/Cadence sensors and uploaded to Wahoo’s app. Still, I find they’re accurate enough to justify the cost, and should continue delivering substantial value for a long time to come.
