The ALBER ANTRIEBSTECHNIK GmbH SERVO makes it possible for wheelchair users — even with reduced strength — to move independently and increase their range of action.

Its standard program to drive uphill and downhill as well as its intelligent braking function make driving safely up- and downhill feasible. The working concept of the SERVO combines physical power and active mobility while it relieves joints and muscles.

The ALPHA concept is the new measure of all things concerning state-of-the-art engines in connection with the newly developed battery pack with lithium ion technology.

High-capacity motors, discreetly blending into the wheels, support the wheelchair user’s initial movement.

The wheelchair user’s impulses on the gripping rings are registered and put into motion due to the newly developed, intelligent sensor system.

The gearless SERVO initiates an entirely new driving feeling without making noise.


Let yourself be enthralled by the unique design that combines power and elegance.
