First modification
A request to adapt an existing prosthetic for extreme sporting use sparks the idea for a purpose-built solution.
Arma Lab develops durable upper-limb prosthetic solutions for active users — engineered for sport, speed and everyday freedom.
It started in 2010 with a simple request: modify an existing prosthetic device for extreme use. What began as a one-off modification grew into something far more ambitious.
Péter Bengő saw what was missing — a prosthetic built not just for daily life, but for sport. For speed. For riders who refused to give up the handlebar. He invented a new construction that would become the ARM-XR. The first real test was deeply personal: a custom-built arm, individually tailored for a 5-year-old boy, every part made by hand.
From a single prototype to a certified medical device — a timeline of innovation, persistence and precision.
A request to adapt an existing prosthetic for extreme sporting use sparks the idea for a purpose-built solution.
The ARM-XR construction is invented: a fully mechanical arm with the same movement axes as the human arm and a unique locking–releasing system.
ARM-XR is custom-fitted for a 5-year-old boy — the first real-world test. Every component crafted by hand.
Arma Lab moves to high-precision CNC machines, scaling production while holding the strictest quality standards.
Founder & Product Development Expert
With a strong background in technical supervision, martial arts, motorsport and anatomy, Péter understands firsthand what a sports prosthesis needs to support athletic performance. He has dedicated over a decade to the development of sport prosthetics.
“Sport activity is essential to stay fit and healthy. ARM-XR helps restore the symmetry of movement — and gives riders back what they love.”
ARM-XR is designed for high-load applications where reliability and safety are essential.
Manufactured with high-precision CNC machines and measurement systems, to medical device standards. Quality is never optional.
Designed to restore the symmetry of movement and support balanced muscle development — so riders perform at their best.
The locking–releasing system releases automatically with the handlebar. Every detail is engineered with the rider’s safety in mind.
ARM-XR is built with aerospace-grade materials and medical-grade precision — every unit individually assembled by hand before it leaves the workshop, overseen by the designer for every order.
ARM-XR is a registered medical device, fully compliant with EU regulations. Arma Lab Kft. is a registered medical device manufacturer.
Meets all requirements of the EU Medical Device Regulation, including European health, safety and environmental standards.
ARM-XR carries the CE mark and is registered in Eudamed, the EU medical device database.
The original ARM-XR is sold only through Arma Lab or its authorised partners.
