PROTEOR QUATTRO
PROTEOR QUATTRO INTELLIGENCE THAT MOVES WITH YOU
QUATTRO adapts to your unique gait, delivering smoother transitions and a more intuitive experience, so movement feels natural, and the only thing you feel is in control.
COMFORT IN MOTION
Traditional MPK technology relies on dual-valve systems that open and close between steps, creating lag that disrupts motion and breaks rhythm.
QUATTRO is powered by a single, bidirectional valve capable of continuous resistance modulation. It reacts twice as fast and adjusts within milliseconds to stay in sync with user intent.
The result is smoother motions that feel more natural and more comfortable.
FASTER THAN YOUR BIOLOGICAL REFLEXES
Three high-precision sensors trigger real-time, adaptive adjustments that make each transition feel truly intuitive.
•Angle sensor is 10x more sensitive than traditional MPKs
•Angle sensor sampling rate is 2x greater than conventional designs
ALWAYS ONE STEP AHEAD
