Patented, adjustable caster system

Precision Control

Patented, adjustable caster system

Instead of several welded parts, we use a reinforced and patented caster mechanism in a single hollow-forged component. The fewest possible elements and no moving parts give you amazing driving performance. Ultra-lightweight yet strong and durable without compromising adjustability.

Caster position is optimized for handling, turning, and maximized propulsion efficiency. Casters may be positioned narrower for more maneuverability or wider for greater stability.


A unique twist to backrest folding.

Just grab the patented Twist-Lock bar with one hand and twist it to release, fold and load the chair into your car. With double-locking, you can use the same bar to lift it. It'll also lock without removing your sideguards or low-profile cushion.

The standard option is a release bar (push up to fold) for an ergonomic and quick release of the folding mechanism. You can also choose a lightweight version of the backrest and our proprietary, stylish Freestyle® backrest.

More Lifting Features

User-inspired innovations

All of our knowledge and user feedback influenced the development of Nitrum. Learn how the Nitrum makes your everyday life more limitless.

  • The Freestyle Back is all about freedom of movement. By providing a 360° range of upper body motion, you can freely twist and turn without catching your backrest posts.

  • Breathable fabric with block-and-tackle tension adjustment is easy to tighten, and its double-loop mechanisms will remain secure.

  • We've designed a better wheel lock in terms of function, strength, and even weight.

    • Redesigned housing controls play and improves durability
    • Enhanced wheel lock engagement
    • Transfer-friendly design
    • Available as direct mount, reducing weight an additional 6 ounces.
  • The QUICKIE Nitrum uses a specially processed 7020-series aerospace aluminum. Together with the new hollow forged caster link tubes, we minimize the total weight of the wheelchair. Therefore the open frame is easier to handle and transport in cars or other vehicles.

User-inspired innovations


A perfect fit for EVERY body.

Body positioning is crucial for propulsion efficency. When your weight is balanced incorrectly, your wheelchair is more difficult to push. That's why the Nitrum boasts the largest range of sizes and adjustments in its class, so you can achieve your own perfect fit.


The first integrated LEDs with removable battery.

Mounted on both caster arms, the Nitrum's integrated LEDs will light up your night. The power pack provides up to 4 hours of run time and can be easily detached for recharging or to reduce the overall weight of the chair. How's that for bright?

  • Composite housing is water- and shock-proof
  • Four LEDs per side light up the area around the caster wheels
  • Three modes: high, low, and blink
  • Control box is mounted inconspicuously on the calf strap and includes a detachable and rechargeable lithium-ion battery
