Wahoo Fitness RPM Cadence Sensor

The Wahoo Fitness RPM Cadence Sensor tracks cadence using Bluetooth & displays the data on your smartphone or tablet.

It is billed as easy to use and it works without magnets – and that drew us in, so we decided to put it through the test.

Wahoo Fitness RPM Cadence Sensor: Installation options

Using the Wahoo RPM Cadence Sensor on your shoe

The RPM Cadence Sensor can be worn on your shoe or attached to your bike.

If you use an indoor trainer or multiple bikes, adding the sensor to your shoe is a good option that enables tracking cadence data on the app for both indoor workouts and rides on all of your bikes.

The sensor is just slightly bigger than a quarter and only weighs 7 grams, so it is small and light enough that it is virtually unnoticeable when worn.

Setting up the RPM Cadence Sensor on a shoe is extremely simple.

  1. Take the provided clip and twist the RPM Cadence Sensor into place.
  2. Slide the clip over the velcro strap on your shoe.

Installing the Wahoo Fitnes RPM Cadence Sensor on your bike

The Wahoo Fitness RPM Cadence Sensor can be installed on a bike with zip ties or with double-sided tape.

To connect the sensor to your bike with the silicone mount and zip ties, just as it sounds, the RPM Cadence Sensor is attached to the crank arm using zip ties.

  1. Put the RPM Cadence Sensor into the silicone mount with the blue/logo side facing in. When you have the Sensor inside the sleeve, turn it over and you will be able to see the blinking light through the silicone sleeve.
  2. Put one zip tie through each of the slots on the sides of the mount.
  3. Mount the RPM Cadence Sensor on the inside of the crank arm of your bike.
  4. Spin the crank around to test it and make sure it doesn’t hit the frame.
  5. Cut the ends off the zip ties.

To install the RPM Cadence Sensor with the double-sided tape, the RPM Cadence Sensor is attached directly to the crank arm with the tape and does not use the silicone sleeve.

The double-sided tape is adhered to the back side (non-logo side) of the RPM sensor and then pressed against a clean crank arm (or else it won’t stick and you don’t want to lose the sensor).

I selected the zip tie option and did not test the tape method.  The zip tie mounting seemed more reliable and didn’t require me to clean my bike. It took less than a couple of minutes and was as simple as it sounds.

Wahoo Fitness RPM Cadence Sensor: The Wahoo Fitness App

The sensor works with the Wahoo Fitness App or other cycling apps like Strava, MapMyRide or Cyclemeter.

I downloaded the Wahoo Fitness App to my iPhone 5 for the purpose of this test.

Setting up the app took less than 5 minutes including the app download.

Wahoo Fitness App Step 1: Set up your profile

The first step in setting up the app is to add your preferred unit of measure, age, weight, height and sex to profile.

Wahoo Fitness App Step 2: Connect your sensors

Next, you connect the Wahoo Fitness RPM Cadence Sensor to the Wahoo Fitness App.

To do so, you click + Add New Sensor and give the RPM Sensor a little shake.  When the blue light flashes, it connects.

You then swipe and select “Save Sensor” and select your fitness type.

Wahoo Fitness App Step 3: Record a workout

Next, the fun part – a bike ride.

I tested the Wahoo Fitness RPM Cadence Sensor on a 10 minute ride.

At the beginning of your ride, you launch the Wahoo Fitness app and, after a 3 second countdown, the app begins tracking the cadence.

If you have also purchased the heart rate monitor and/or speed monitor, the data would also appear on-screen for those items (shown as n/a and _ _ on the image for mine since I don’t have those).

We also tested the Wahoo Fitness RPM Cadence Sensor with my existing ANT+ enabled computer and received the same readings.

The Wahoo Fitness app stores your workout data, so following my ride, I went to history on the app to check my average and max cadence.
