⭐️ A custom button allows you to enter your own speed value which can be great for hiit.
⭐️ No calibration or measurement issue.
⭐️ Speed is recorded very precisely.

Auto Mode
⭐️ Put your phone in an arm band
⭐️ Or take it in your hand
⭐️ Running speed will be computed automatically
⭐️ Adjust running speed by setting up step length parameter (we advise you to do this when you are running around 10km/h)

With ANT+ Footpod
⭐️ Bridge ANT+ footpod into Bluetooth Smart sensor with Running Speed and Cadence feature
⭐️ Requires ANT+ native smartphone or ANT+ USB stick

With Garmin watch
⭐️ Use your Garmin watch with its integrated accelerometer
⭐️ Broadcast heart rate from optical Garmin watch sensor to Zwift over BLE
⭐️ In case you get an exclamation mark when starting the watch app, please reboot the watch, start the watch app alone. If you get the same, this means that your watch is probably not compatible with our watch app. In this case we advise you to use the manual mode.

🚨 Important to read with Zwift 🚨
⭐️ If you start and your avatar doesn't move or if you get disconnected regularly this is probably because you are using the Bluetooth direct connection which is selected by default with Zwift on Windows.
⭐️ In this case you need connect through Zwift Companion app on a separate phone
⭐️ If you get multiple 'Speed T', this is because Zwift connect to your device in order to know if running speed is available and the virtual address of your phone changes for privacy reasons. This address change is implemented by device manufacturers and cannot be avoided by developers since it is linked to 'privacy and security'. Don't worry, your phone still have only one address but since it has changed, it appears in Zwift as a new device.
⭐️ We regularly update the help page and strongly advise you to read it carefully when trying to connect Speed Transmitter to Zwift : https://bipr.fr/treadmill-speed-transmitter
