Visible parts of the Küschall K-Series have been kept to a minimum, creating a sleek, dynamic and lightweight design. The K-Series concept features a monotube rigid frame with a separate seat module allowing adjustments to be made easily and independently from the frame. The K4 weighs just over 20lb and gives a great driving performance. The front frame has a 78° angle for a more extended leg positioning. The extremely manoeuvrable AirLite has new shorter forks which, together with the 90° angle of the front frame, reduce the overall length by 6cm, bringing the weight to under 20lb! The AirLite Pro meets the highest of expectations. Its unique use of titanium and aluminium makes it the lightest adjustable wheelchair on the market, combining best driving performance with manoeuvrability.
