Hailed as the world’s smallest power meter, the AroFly monitors cycling power from its position on the tire valve.
The AroFly measures the rider’s pedaling power, cadence and speed with its patented “Dynamic Pressure Variation Principle” technology. By continuously detecting the spikes in the tire pressure during pedaling, the tiny AroFly can determine the riders cadence, while an integrated accelerometer measures speed. The collected data is transmitted to AroFly A-Plus Meter cycling computer or a paired smartphone, displaying the rider’s power output in real time with an accuracy of +/- 2 percent.
