What Is the PX12 XSTO?

Not just motor power,
but adapting to the terrain.

A conventional power wheelchair is designed for one type of surface: flat, firm and predictable. The PX12 XSTO's design also takes stair transitions, slopes, sand, grass and uneven outdoor conditions into account.

Its tracked climbing mechanism, independent power and suspension on all four wheels, dynamic seating system and AI-assisted environmental hazard detection work together. It is therefore more accurate to consider the PX12 XSTO not simply as a wheelchair, but as a mobility system that responds to different terrain conditions.

Tracked Climbing System

Stairs up to 40°,
30–35 steps per minute.

The PX12 XSTO's most distinctive feature is its tracked climbing system for stair use. The manufacturer's product information specifies stair-climbing capability up to 40° and a climbing rate of approximately 30–35 steps per minute.

350mm

Gap-Crossing Capacity

Maintains mobility across breaks in the surface, openings and transition gaps.

150mm

Obstacle Clearance Height

Helps cross everyday outdoor obstacles such as curbs, thresholds and single steps.

Safety note. Stair use is a high-risk driving scenario. Always follow the manufacturer's instructions and safety procedures, taking the product's actual operating conditions into account.

Multi-Mode Drive System

Not limited to
a single driving style.

As the terrain changes, so does the driving configuration. Three modes adapt the product's movement to the situation.

Dynamic Balance & AI Safety

When the ground tilts,
the seat stays level.

The dynamic seating system adjusts seat height and angle as the terrain changes, helping the user maintain a more balanced and natural position. The AI-assisted environmental hazard detection system is designed to identify potential risks in the surroundings.

Dynamic Height

Height adapted to the situation

Seat height can be adjusted dynamically according to the usage scenario.

Dynamic Angle

An angle that adapts to the terrain

Helps the seat angle adapt to changes in the ground surface.

AI Safety

Environmental hazard detection

The AI-assisted system is designed to support the user by detecting potential risks in the surroundings.

Safety note. Intelligent safety systems do not replace the attention of the operator and user. Follow the product's operating instructions, particularly on stairs and steep inclines.

Control & Transport
