Conventional power meters are expensive, cumbersome and complicated. AROFLY is the size of a bottle cap and is easy to install. It is a smart power meter, weighing only 10 gram. AROFLY is the perfect partner and complements the biker’s need for scientific training. AROFLY LINK will meet the requirements of different cyclists. AROFLY LINK is compatible with most of the bike computers available in the market. It is easy to use through simple installation, pairing, and basic setup. Exclusive Dynamic Pressure Variation Sensing Technology When compared to the current strain gauge system of power meters, AROFLY has developed a new generation of power meters based on an Exclusive Dynamic Pressure Variation Technology, making the power meter easy to use, lightweight, and more affordable. By measuring torque and angular velocity, the strain gauge can calculate power. Such measuring devices, used by most cycling power meters in the market, such as Chain ring type, Crank type, Wheel Hub type, and Pedal type, etc. must be attached to the transmission system to detect the position of the force. AROFLY measures road conditions and tire pressure variations. AROFLY uses an exclusive measuring technology to provide cycling information to the AROFLY series. Information such as road conditions and tire pressure variations are processed through the AROFLY algorithm. It collects data from the power sensor, cadence sensor and via algorithms to provide immediate riding data to the AROFLY series. We can review the complete riding stats on the “AROFLY 2” APP and AROFLY CLOUD. This invention and algorithm technology is patented in Japan, China, Taiwan, Europe, USA and Canada. 100% SAFETY 100% FOCUS RIDING Every biker has experienced a puncture. Low tire pressure can affect a cyclist’s power, safety and riding performance, while cycling. AROFLY power meter includes the tire pressure monitoring system, to measure the rear tire pressure and displays a warning message to ensure a safe ride.
