ANT+ Bike Sensors? What are they?

Speed and cadence sensors measure how fast you’re traveling (in km/h or miles/h), and how fast you’re pedaling (in rotations per second), respectively. Most sensors today are either ANT+ or Bluetooth Smart.


If you have ANT+ sensors, your phone won’t be able to read them unless you use VELO to convert them or you have an ANT+ adapter for your phone (or you have some kind of ANT+ phone like old Samsung and Sony ones). If you have Bluetooth Smart sensors, you don’t need to do pairing with VELO; your phone can pick up the signals directly from the sensors.
