The motors are in the centre of the wheels. The direction will be regulated with different wheel speeds. Forward and reverse run is beginning with soft start. Revolve round a point is possible. The motor also functions as a generator, so it can be used as a brake. Due to the high efficiency the utilization of smaller batteries is possible, keeping the same action radius. The same energy of the batteries means a double action distance compared with traditional motors. A climbing gradient of 25 % is possible. No gear and the length of motor not more than the length of a standard hub means  that the wheel chair can be folded up very easy and quick. The weight is clear lower.

A grip, to turn outside of the motor, allows to open the electromagnetic safety brake by hand. In this case the controller is automatically without function. Thus the wheelchair can be moved like a normal one.  Each motor is connected to the controller and power supply by a cable with a quick release connector. It is a shielded version of a bayonet locking system. To open the quick release couplings and pull out the connectors gives a short time to disassemble the wheelchair. Batteries (24V) and microprocessor controller are protected against water in a plastic case. All control elements  - as well as the charger - are fixed by quick release connectors.
