EBS refers to "Ergonomically, Balanced and Stride", means elastic knees insurance. The EBS has the function of providing 0-15 degrees flexion shock absorption for the knee joint when walking in order to make the patients’walking more comfort and graceful.Especially in the complex situation of down slope surface, it perfectly plays a unique dual EBS function to bring you a harmonious and relaxing natural gait. Dual EBS elastic knee can also eliminates ground shock to the stump,walking more comfortable;
◆ Incorporates a unique knee joint locking function imitating the human knee joint to ensure that the prosthetic knee operates safely in heel strike phase and stance phase like a human knee. In take-off phase, the prosthetic knee can imitate the human knee to unlock the knee joint and walk easily and naturally with knee flexion. This third-generation bionic geometric lock function successfully solved the problem that AK prosthesis cannot be used for the blind.
◆ Extended high-power dual-cylinder design, capable of adjusting the extension resistance and flexion resistance according to a specific user's condition, reducing physical consumption and improving gait, enhancing the patient's walking ability
◆  Multi-axial knee joint design to achieve balanced load for the rotary bearing in stance phase and greatly increase the service life of the knee joint body.
◆ The precision design of sealed needle bearing knee joint differs from the conventional ball bearing or bushing design currently available on the market, greatly increasing the product service life.
◆ Applicable to weight limit of 136 kg, especially for the amputees of heavier body weight and labor intensity;
◆  Large flexion angle design, providing more convenience for the users.
