The AIRsistant sensor is shipped de-activated and must be activated to display the data on the compatible device. To activate the AIRsistant sensor, install it on the wheel and pump the tyre above 0.3 bar (4.35 psi). It may take up to 20 seconds for data to be shown on your display device. Once the data appears on the display the AIRsistant sensor is activated.
Transmissions are triggered automatically by making a minimum of a quarter turn with your wheel. The AIRsistant sensor will also send transmissions during tyre inflation or deflation making pressure adjustments easy and providing a great alternative to tyre pressure measurement devices.
The AIRsistant sensor will automatically stop transmitting if stationary for 120 seconds. The AIRsistant sensor will turn off automatically after 5 minutes of inactivity and automatically restart as soon as you move your bike again.
Data is transmitted using Bluetooth Low Energy.
Data from the AIRsistant sensor can be displayed using the iOS or Android AIRsistant smart device app. It is also possible to display the data from AIRsistant sensor on a compatible GARMIN device.
The data measured from the AIRsistant sensor can be shown on compatible Garmin devices. However, only one display device is permitted at a time. Data from the AIRsistant sensor cannot be displayed in the AIRsistant smart device app and on a compatible Garmin device at the same time.
No. The AIRsistant sensor transmits via Bluetooth to the AIRsistant smart device app and compatible GARMIN devices.
Make sure the AIRsistant sensors are activated by rotating them for several seconds or via a tyre pressure change. The Bluetooth function on the phone must be switched on. For Android phones, the location function (GPS) must be activated when it is first connected. The AIRsistant smart device app should take care of both.
The AIRsistant sensor is compatible with tube and tubeless tyres.
The AIRsistant sensor can measure tyre pressure in the range of 0.0 to 8.3 bar (0 to 120 psi).
The AIRsistant sensor is compatible with tyre diameters from 20” to 29”. Compatibility depends on the spoke distance for smaller diameters.
Yes. 2-, 3- and 4-wheel bike profiles are available in the AIRsistant smart device app. AIRsistant sensors are available in dual or single packs.
No. The AIRsistant is compact and lightweight with only 21g per sensor.
The AIRsistant sensor is compatible with Presta/ Sclaverand (SV) and Schrader/ Auto (AV) valves. Service kits are available in case you want to keep using your AIRsistant sensors but need to change the valve.
AIRsistant sensors are designed to work exclusively with a smart device app/system developed by Schrader and authorized partners. The AIRsistant sensors are fitted and secured using the top locknut to prevent theft.
The pressure warning levels can be set and adjusted by the user depending on requirements. However, it is recommended to raise warning by +/-20% from desired placard. You can use the pressure calculator functionality in the AIRsistant smart device app for recommendations. The app issues a warning and marks the tyre in red when your tyre pressure goes below or above the pre-defined warning levels.
The AIRsistant sensor measures very accurately with a pressure accuracy of +/-1% full scale and a resolution of 0.01 bar / 0.14 psi and a temperature accuracy of +/-3°C and resolution of 1°C.
You inflate your tyre the same way as you would usually do. The AIRsistant smart device app includes a digital tyre gauge function reflecting pressure changes on your display device, making pressure adjustments easy and providing a great alternative to tyre pressure measurement devices.
No. The AIRsistant includes a lifetime battery up to 5000 operating hours. That makes AIRsistant a maintenance-free, fully sealed system optimal for off-road.
