The 5 best cycling cadence sensors for your bike

biking at sunrise or sunset from handlebars

There are some measurements where a bike computer alone just won’t cut it when it comes to cycling data. If you want to know your cadence – the number of rotations your pedals make every minute – you’re going to need a cadence sensor.

Understanding your pedaling speed is one of the quickest ways to see drastic improvements in your cycling.

With a sensor, you can train yourself to increase and maintain your rotations, while post-ride data allows you to compare yourself with the pros.

And the best news? You can use a cadence sensor on all bike types, including indoor stationary exercise bikes used for things like spin classes! So if you joined Peloton or Apple Fitness+, you could use these sensors to up your workout.

Need some solid recommendations for choosing your next cadence sensor?

We love using a cadence sensor when we cycle. Why? Because these small, relatively inexpensive sensors really help us maximize our bicycle workout results.

Think of them as a bike version of your auto’s speedometer or a walker and runner’s pedometer.

And they are really easy to add to your bike. Attach your cadence sensor to one of your bike’s crank arms–that’s it!

With a cadence sensor, we can measure our body’s energy output in the form of rotations per minute (RPM). Knowing that information can help you stay on track of keeping your RPM at a set rate or trying high and low cadence intervals.

So let’s take a look at the top five devices that need your attention.

Garmin Cadence Sensor 2

At less than $35 the Garmin Bike Cadence Sensor is a great budget option. There are no magnets here. Instead, you secure the sensors to any crank arm size using one of three included bands.

It’s super easy to install and ideal for quickly switching between bikes with no exposed parts to line up. Attach and get riding.

Ant+ connectivity and Bluetooth Low energy technology let you sync to Garmin Connect and other training apps, compatible devices, and fitness equipment for better data when you ride indoors and outdoors.

Magene S3+ Speed and Cadence Sensor

Magene S3+ Speed and Cadence Sensor’s nifty power-saving mode automatically sleeps when the sensor detects no motion for 10 seconds, waking up and transmitting data after 3 seconds of riding.

It means it’s got an incredible 400-500 hours of battery life. Easily attach the sensors using the included bands, and you’re away.

With the Magene only weighing 8.8 grams (0.31 ounces), your riding won’t be affected. It’s compatible with all devices which support Bluetooth or ANT+, giving you precise, as-you-ride data.

However, the tech doesn’t support Strava Map My Ride and individual sensors can only record either speed or cadence, never both at the same time.

CooSpo Cadence and Speed Bike Sensor CooSpo Cadence Sensor for bikes

The CooSpo Cadence Sensor is one of the cheapest Bluetooth sensors on the market, setting you back less than $25. Plus, there are no magnets, and a single sensor works for either speed or cadence.

And this sensor is very easy to install!

Bluetooth and ANT+ 4.0 integration mean it works with fitness apps like Zwift, MapMyRide, Trainer Road, RidewithGPS, Peloton, Wahoo, Cyclemeter, Rouvy, and Strava.

And, connecting with your phone or bike computer will let you receive real-time speed and cadence statistics.

We also love that the battery is replaceable! Just pop in a new and relatively inexpensive CR2032 battery, and you’re ready to go.

The CooSpo is simple to set up and attaches directly to your bike’s crank arm or axle. However, its downfall is its inflexibility.

  • First, to switch between cadence and speed recording, you have to get off your bike and reinstall the battery to reset it to switch between speed (red status light) and cadence (blue status light). This sensor can’t capture speed and cadence at the same time.
  • Second, it does not work well on spinning bikes, giving inaccurate readings due to the magnetism that interferes with the cadence speed sensor’s signaling.

But, for less than the price of an expensive meal, it takes an accurate reading with brilliant smartphone compatibility.
