Livall Nano Cadence Sensor

With the Nano Cadence Sensor set on your bike’s crankset hole, the LIVALL Riding App can show the cadence of your cycling, and (based on that) your speed, traveled distance and burned calories. Seeing the numbers go up will boost your performance! The LIVALL Riding App can also show slope rate, altitude, and heart rate when you connect designated extension devices to your phone.
