Editor’s Note On Indoor Cycling Cadence and Speed Sensors!

Cadence sensors are compatible with any spin bike, no matter the design because they simply attach to the pedal cranks and every spin bike has two pedal cranks/crankarms (one on the right and one on the left). However, speed cadence are not compatible with all indoor bikes. Especially if your spin bike flywheel is located in the back.

The reason for that is because speed sensors need to attach to the flywheel. And unfortunately, some flywheels don’t have sufficient space (minimum 10mm) between the flywheel and the fork arm. So, before buying a speed meter for your indoor bike, I suggest you check out the gallery of images below.

These are real successful installation of spin bike Wahoo cadence reader and speed readers. By looking at these Bluetooth and ANT speed/cadence sensors, you should be able to draw a certain conclusion to whether you can buy indoor bike speed and cadence sensor or not.

Note: If there is enough space between the flywheel and the fork arm, install the speed sensor horizontally (seen in some images below), it’s much better in terms of speed and distance accuracy. The following spin bike speed and cadence sensors that you see in the images are by Wahoo (not Garmin) but ultimately they work the same.

  1. I have a LeMond Revmaster Spin Cycle with a solid wheel – so there is no hub on which to fasten a speed sensor. Also, the clearance between the frame and the side of wheel is ~0.2 inches (5 mm) which is not enough clearance to glue a sensor to the side of the wheel.

    In the past, I have been using a very old wired Avocet 25 bike computer with a very thin magnet glued to the side of the wheel but the Avocet is now giving me problems and I would like to go wireless.

    Any ideas?
