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.
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.
