The SERVO — performance with style
High-capacity motors, discreetly blending into the wheels, support the wheelchair user’s initial movement. The SERVO responds to you pushing the wheels and adds power of its own, thanks to the improved sensor system. All without noise, thanks to its gearless design!
Easily mobile — everywhere
The SERVO – powered wheels are disengaged easily and without tools. Any foldable wheelchair with the SERVO attached can be folded as normal! The SERVO fits into almost into any car boot.
Due to the SERVO’s new wheel mounting system, NUI, the powered wheels are easily stored next to or on top of each other.
ALPHA — a synergy of power and effortlessness
ALPHA – AAT Lithium Power High-range Accumulator – is AAT’s new battery technology. Simply put, it’s the reason why a battery weighing only 4.2 kg can take you up to 55 km.
NUI – innovative technology for mounting and locking
The newly developed mounting and locking system, NUI, does not need stud axles any more, which makes fast and effortless mounting of the powered wheels possible.
The SERVO can be mounted to almost any wheelchair – no need to do without the chair you are used to!
