Troubleshooting FAQ

Why won't my Speed sensor pair to my phone?

  • To ensure that your Speed sensor pairs directly to the app you have downloaded, please ensure you have an ANT+ adapter installed or that your phone is ANT+ compatible

I am struggling to get an MPH/KPH reading from the Speed sensor and it doesn't show up under the list of sensors?

  • This can be caused by the sensor not being attached securely to your bike forks or the magnet is not correctly inline with the sensor. Please ensure that the magnet is directly inline with the sensor and the LED light flashes when the magnet is detected. If paired to a GPS ANT+ bike computers or cycling apps, check to see if the device is using GPS for speed, on some ANT+ devices you will need to select the ANT+ Speed sensor as the source for bike speed and distance.

Can I pair my Speed /sensor with another phone or app or ANT+ device?

Can I pair my Speed Sensor to my phone app and ANT+ device at the same time?
