This Tacx sensor measures your speed and cadence and transmits this information wirelessly via ANT+ and Bluetooth^® Smart technology to the devices it is linked to, such as a smartphone, tablet, sports watch, GPS device, bike computer or Tacx trainer. Many sports devices used during training either use ANT+ or Bluetooth^®, but not both. The Speed & Cadence sensor uses both communication techniques, enabling you to keep track of your performance any way you want.

Connect the sensor, for example, simultaneously to your smartphone via Bluetooth^® and to your sports watch via ANT+. Or check your speed and cadence quick and easily on your smartphone via popular sports applications like Endomondo and Strava. 

Please note: the Tacx speed & cadence sensor is not compatible with the Tacx applications for tablets and smartphones.

Bluetooth^® version
To use the Speed & Cadence sensor you need Bluetooth^® 4 or higher. 
If you have a different version of Bluetooth^® and want to link the Speed & Cadence sensor to your smartphone or tablet, then you can use a receiver especially developed for this purpose. For an Apple device (iPhone) you can use the existing Wahoo ANT+ Dongle. For a device with micro USB input you can use the new Tacx ANT+ Dongle micro USB.
