Functional benefits

Quickie-Nitrum-Casters

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

Quickie-Nitrum-Backrest-Release-Bar-Arrows

Release Bar folding mechanism (standard option)

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.

Quickie-Nitrum-Twist-Lock-Backrest-Arrows

Option of a unique twist-lock folding backrest

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.

Quickie-Nitrum-Tension-Adjustable-Upholstery-medium-image

Tension-adjustable seat sling

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

Freestyle Back

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. 

Quickie-Nitrum-Wheel-Lock-2

Compact wheel lock

Designed with a better wheel lock in terms of function, strength, and even weight.
Redesigned housing controls play and improves durability.

Quickie-Nitrum-Titan-Transport-medium

Easy transport

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.

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.
