Power Positioning Functions
Sky-High Power Elevating Seat
Reach new heights with the power elevating seat. The seat is mounted into the chassis and can be raised stepless up to 40 cm. This provides the users with a better view and better access to their surroundings.
50-Degree Center of Gravity Tilt System
The center of gravity tilt system ensures pressure relief and a high degree of comfort. The tilt can also be used when traveling down a slope to compensate for the negative seat angle. This provides a safer and more stable seating position.
Biomechanical Power Recline and Elevating Legrest
180° power recline together with 180° power elevating legrest, total flat position allows the user to lie down straight. With the biomechanic design, the seat traverses with body movement, minimizing the effect of shearing force, keeping all the supports in the correct alignment with the body, and ensuring sitting stability.
Front-Wheel Drive Performance
Best in Class Driving Range and Performance
Despite its low seat height, the front-wheel drive EVO chassis is compatible with up to 80Ah batteries, which yield up to 54 km of driving range. The narrow 610 mm width of the EVO chassis allows users to precisely navigate indoor environments.
The maintenance-friendly battery box design also allows technicians to remove and replace the battery while the user is seated.
Ultra-Low Seat Height
The EVO Altus and EVO Lectus LR feature an ultra-low 415 mm seat-to-floor height, enabling users to comfortably operate wheelchair-accessible motor vehicles and pull up to tables, offering increased comfort and accessibility in daily life.
Fully Adjustable Suspension
The strong and compact EVO chassis is equipped with a fully adjustable 4-wheel suspension system. The stiffness of the suspension can be configured according to the user’s weight, ensuring a smooth ride outdoors.
Highly Configurable Rehab Seat
Altus and Lectus
These products feature the best driving performance, biomechanical positioning, highly configurable and adjustable seating systems, and support for most third-party accessories and controllers, allowing users to enjoy a life of independence and unlimited possibilities.
