A cadence monitor is a fantastic piece of equipment for any serious spin bike user. It allows you to monitor your speed and distance, making it possible to keep track of your pedaling sessions. Besides, it even allows you to increase or decrease the speed and intensity of your spin bikes.

What does it mean that the speed sensor is not compatible with my spin bike?

In some spin cadence sensors, the speed component is not compatible with spin bikes. Although this may sound alarming, it is quite normal.

The speed sensor typically mounts on a bicycle wheel hub to measure the wheel's rotational speed. This speed is then multiplied by the wheel's size, which will give the reading of the speed.

This is not easily possible in spin bikes because they come with a solid flywheel that often doesn't provide access to the hubs. Therefore, the readings from the speed sensor become tricky to measure. This is why it is paramount that you check the sensors' compatibility with your spin bike before you purchase one.

With the sensors we've presented, you won't have to worry about this issue. They are all capable of being fitted to your spin bike. The only complication will be the type of exercise bike you own.

How difficult is it to mount cadence and speed sensors on a spin bike?

In most cases, installing a cadence monitor is pretty straightforward. To do so, you need to hook up the sensors to the flywheel and crank arms.

Then all it requires is syncing up the sensors with your device of choice, and you are ready to start pedaling. The best cadence monitors for spin bikes come with wireless technology, so it should be quite easy to pair the sensors with your devices.


Cadence monitors are an integral part of spin bikes, especially if you take cycling more seriously than a hobby. Research has shown that cyclists who pedal at a cadence of 80rpm or more build endurance and burn more calories. So this seemingly small device can be an excellent way to keep track of your exercise efficiency and allow you to be on top of your cycling game.

Our recommendations of the best cadence monitor for spin bikes cover a good range of choices. So whether you are looking for a high-tech cadence monitor or an affordable speed sensor or an interactive one, you should have no problem getting your pick.
