Technical Information

Note that not all smartphones or tablets are compatible with Bluetooth Smart technology! Check the compatibility of your device at you have an Android device, you can also use the "Decathlon Utility" app.
Check out our installation video for installation instructions. The sensor features a LED to indicate that the device is properly installed. When the magnet is positioned correctly the LED will flash every time the magnet passes in front of the sensor. The LED flashes yellow for the speed sensor (magnet mounted to a rear wheel spoke), and red for the cadence sensor (magnet on the crank arm). The LED stops after flashing 10 times.
App compatibility.
We recommend the free "Wahoo Fitness" app for connecting the sensor to your smartphone. The sensor is also compatible with Strava, but this app can also make use of cadence data. For speed, Strava only uses the GPS on your smartphone. We have not tested the compatibility of the sensor with other apps, and so we cannot guarantee that it will work correctly with other apps.
Installation instructions.
The sensor cannot be directly connected to your phone using the Bluetooth settings on your phone. It must be connected directly using the app of your choice. We recommend the "Wahoo Fitness" app.You need to pedal for the sensor to be detected.

I installed following every step closely, leds working, detected by my phone (Nexus 5x, android N) but the app can't connect to it (Strava premium and Runtastic) even my Tomtom Spark watch can't connect to it. It's really frustrating...

Excellent Product
Used for 1 week or less
Easy to install finds Bluetooth easily. Found it connected and uploaded to 'Map My ...etc' with no problem although app requires upgrade to premium to view all data. Connects to Cyclemeter again with no problem and Elite upgrade is fairly cheap and collects and displays data.
Easy to install and connect to phone.
None so far
Appears to be working, as I can see the lights flash when the crank and wheel turns.I can also see the Bluetooth is being picked up by my phone. Absolutely no apps seem to work with this including the Btwin kinomap app which has paired but fails to do anything when the pedal and wheel is moving, more importantly strava denys it's very existence: unless decathlon can give me some input here it's going straight back to the store!!
