AAT SERVO – Intelligent Power-Assist Add-On Drive for Manual Wheelchairs

Description The AAT SERVO is a premium power-assist add-on drive that transforms a standard manual wheelchair into a smart, motor-assisted mobility solution. Designed to amplify the user’s pushing force, the SERVO automatically detects each hand-rim impulse and provides the precise amount of motor power required. This reduces strain on the arms and shoulders while allowing the user to maintain full control of speed and direction. Developed for both indoor and outdoor environments, the AAT SERVO offers powerful assistance on ramps, hills, and uneven terrain. Its intelligent sensor system ensures natural and intuitive driving — automatically adjusting the level of assistance to the user’s input.

Thanks to its tool-free quick-release mounting system, the SERVO’s powered wheels can be easily attached or removed, making transport and storage simple. The system fits most standard manual wheelchairs and offers a range of up to 55 km per charge, ensuring reliable performance throughout the day. The AAT SERVO is ideal for users who wish to retain the freedom and manoeuvrability of a manual wheelchair while benefiting from electric power assistance.
