The CHIGEE TPMS is designed specifically for motorcycles and supports two tires only — front and rear.
The standard package includes two tire pressure sensors, and the system can monitor up to two channels at once.
This configuration fits the vast majority of motorcycles, which have two wheels.
At present, the system does not support three- or four-tire setups, such as those found on trikes or sidecar motorcycles.
If your vehicle has more than two wheels, additional tire monitoring is not available within the current TPMS design.
