Invader – passion in perfection
Benefits at a glance
The box-frame wheelchair is permanently welded and formed from a single tube. Even the caster fork is manufactured from one piece, and the footrest can be welded as well.
Custom design without compromise
The box-frame offers optimal handling, while the custom design provides maximum individuality. And the sporty shape of the frame combines extreme sturdiness with a low net weight. Simply unbeatable.
Optimum driving characteristics
The Invader is extremely sturdy yet highly manoeuvrable.
For large and small
Flexible custom fabrication also meets special needs and is tailored to individual proportions.
Individually made to order
Every single length and angular dimension in the design meets the customer's wishes. Our experts prepare a 3D CAD simulation according to your body measurements to fabricate your Invader.
7020 T6 aluminium, the strongest still weldable aluminium, is used for the aluminium alloy. The material is cut to size, custom bent, and welded to make the frame. The finished frame structure is refined in a 3-stage stress-free annealing process.
