The DNSYS Z1 is a cutting-edge knee exoskeleton developed by Hong Kong-based startup Dnsys, founded by robotics experts who previously worked for companies like Segway, DJI, and Xiaomi. Unlike its predecessor, the X1, which focused on hip support, the Z1 targets the knee joints, responding to user feedback for more assistance in this critical area.

The Z1 uses AI-powered motors to deliver continuous power to the wearer’s entire leg, helping them climb higher, walk farther, and push past their limits. Whether you’re hiking steep trails, climbing stairs, or simply walking longer distances, the Z1 reduces muscle fatigue and makes every step feel lighter.

Key Features

50% Leg Strength Boost

The DNSYS Z1 delivers up to 50% intelligent leg assistance, tackling slopes, challenges, and heavy loads. Its independently developed knee motor delivers up to 900W of power, with a unique design that transmits force simultaneously to the thigh and calf backs, generating lifting and pushing support for double output.

200% Knee Pressure Relief

While skiing, knees can bear up to 700% of body weight; hiking puts them under 500%; even walking downstairs adds 300%. The Z1 uses AI-powered motors to evenly deliver force to the backs of the thighs and calves, providing intelligent cushioning that disperses and absorbs impact on the knees. It offloads up to 200% of body weight from the knees.

AI-Powered Intelligence

Each exoskeleton unit features a dual-core 240 MHz processor running AI algorithms that learn the user’s walking, running, or climbing patterns over time. Onboard torque, position, and force sensors detect leg movements and trigger motor assistance in just 0.01 seconds. The AI can recognize movements and switch assist modes for activities including walking, running, cycling, jumping, squatting, sitting, and standing.

Ultra-Lightweight & Portable

Each exoskeleton unit weighs just 680 g (1.5 lbs). The hinged design fits in a backpack and can be mounted on each leg in a claimed 15 seconds. Despite adding only 1.4 kg of weight, the lift-assistance makes the user feel up to 20 kg (44 lbs) lighter when moving uphill, standing up, or performing repetitive leg motions.

Extended Range & Kinetic Energy Recovery

The Z1 extends hiking range by up to 15.5 miles (25 km) and vertical climbing by 9.3 miles (15 km) on a single charge. The KERS kinetic energy recovery system recharges the battery using energy generated from downhill movement, prolonging battery life by 20% and retaining 80% capacity after 2 years of heavy use. Each lithium-ion battery lasts up to five hours, depending on activity.

Health Management via App

The Dnsys app monitors medical-grade health data in real time, empowering users to customize training plans and optimize every adventure.

Quick-Swap Batteries

Swappable batteries provide hours of powered mobility assistance, with quick-swap capability for extended treks.

Technical Specifications

All specifications are based on official DNSYS product data. Actual performance may vary with operating conditions.

Available Models

DNSYS offers the Z1 in three models to suit different needs and performance levels:

Use Scenarios

Hiking & Mountain Climbing

The Z1 extends hiking range by up to 15.5 miles and vertical climbing by 9.3 miles. It reduces muscle fatigue for farther walks, higher climbs, and effortless movement. With intelligent gait control across rugged trails, stairs, and slopes, the Z1 makes every climb feel significantly lighter.

Trail Running & Cycling

The AI recognizes running and cycling movements, switching assist modes to provide optimal support. Runners experience improved pace and reduced fatigue over long distances.

Stairs & Urban Mobility

Whether climbing multiple flights of stairs or navigating city streets, the Z1 provides intelligent cushioning that disperses and absorbs impact on the knees. Users report stairs are “so much easier” with the Z1 power boost.

Skiing & Snow Sports

The unique three-point structure transfers motor force to the back of the thigh and calf, easing pressure on the knee and boosting stable leg support—making it well-suited for active scenarios like skiing.

Emergency Services & Firefighting

Volunteer firefighters report the Z1 makes a real difference in their line of work—when running a charged hose line, especially up stairs, it helps maintain stride so they can focus on fighting fires instead of fighting fatigue.

Everyday Mobility & Health

The Dnsys app monitors medical-grade health data in real time, empowering users to customize training plans and optimize every adventure. For those with knee concerns or limited mobility, the Z1 provides daily support for walking, standing, and squatting.
