DYNAMIC MOVEMENT
Movement that adapts to the moment.
Daily movement is constantly changing. Walking, standing, climbing stairs, and rising from a chair all place different demands on the body.
​
BionicM's patented Bionic Variable Reduction Gear (BVRG) helps deliver intelligent powered assistance by adapting torque output as knee movement changes, creating support that feels more natural throughout everyday life.
Every movement asks something different of the body.
RESPONSIVE MOVEMENT
RESPONSIVE MOVEMENT
Every movement asks something different of the body.
Walking across a parking lot feels different than climbing stairs. Standing from a chair requires different support than slowing down or changing direction. Everyday movement is constantly changing.
​
Powered prosthetic technology should adapt alongside the user—not require the user to adapt to it.
​
That is why responsive movement matters.
PATENTED TECHNOLOGY
Bionic Variable Reduction Gear (BVRG)
Bionic Variable Reduction Gear (BVRG) is BionicM's patented transmission technology that changes mechanical advantage as knee angle changes.
Instead of delivering power the same way throughout movement, BVRG allows the system to emphasize efficient walking while providing greater torque during functional activities like sit-to-stand and stair ascent.
​
The result is powered assistance that feels more responsive because it adapts to how people naturally move.
Support adjusts throughout daily movement.

BVRG IN ACTION
Different movements
require different support.
Walking and standing place very different demands on the knee.
BVRG changes transmission characteristics as knee angle changes, allowing the system to emphasize efficient movement during walking while providing greater torque where functional tasks demand more assistance.
​
This adaptive approach helps create powered movement that feels more natural throughout daily life.
HOW WE THINK
A Different Way to Think About Powered Movement
Powered assistance should never feel overpowering or delayed.
​
Instead, it should respond naturally as movement changes, helping users move through everyday life with greater confidence while giving clinicians technology that feels intuitive to fit and explain.
01
Adaptive Assistance
Support changes as movement changes, helping deliver assistance where and when it is needed.
02
Mechanical Intelligence
BVRG changes transmission characteristics as knee position changes to better match functional movement demands.
03
Natural Motion
Responsive support helps create movement that feels fluid, intuitive, and more aligned with everyday mobility.
CLINICAL VALUE
Advanced engineering with practical clinical value.
Clinicians need powered technology that feels practical, reliable, and explainable.
​
BionicM’s focus on stability and safety helps support clinical confidence by emphasizing predictable device behavior, reduced risk of false triggers, and intelligent support in daily mobility.
​
This gives clinicians a clearer way to discuss powered prosthetic technology with patients: not simply as advanced technology, but as support designed around confidence, control, and trust.
BVRG is more than a technical innovation.
It is a design approach intended to improve how powered assistance is experienced by patients.
​
By adapting support throughout movement, clinicians can introduce powered mobility that feels more natural during walking, functional activities, and everyday life.
