The development of our wheelchair models from the ideas through the first draft to production takes place entirely in-house.

We only use EN AW 7020-T6, a high-strength aluminum alloy from the AlZnMg group (AIZn4.5Mg1) from the 7xxx series with a 4 to 5% zinc and 1.0 to 1.4% magnesium content. With a strength of 350 to 600 N / mm², it is the strongest still weldable aluminum alloy. This alloy is used worldwide in aircraft construction, motorcycle frames, armored vehicles, bridge construction, race cars, high-performance sports equipment.

Manuel Onken’s participation in the 2002 World Wheelchair Basketball Championship in Japan required a newly designed wheelchair. These were the beginnings of our first custom-made basketball wheelchair. Continuous improvements to the frame and production processes now provide a highly developed and mature product.

The frame geometry is a permanently welded construction. The Challenger is tailored to the player according to several criteria and custom-made in a special construction. Body size, classification and indication are adjusted. Construction is carried out in accordance with the IWBF regulations.

By reducing the total weight by more than two kilograms without having to forego frame rigidity, the Challenger is one of the “top athletes” among basketball wheelchairs.

The Challenger basketball wheelchair is a light, fast and strong wheelchair, built for the demanding athlete.

The Challenger is also available for other sports!
