The QUICKIE Nitrum, where energy becomes effortless motion - Meet the lightest in its class
Achieving a lightweight, rigid wheelchair without compromising on stability or performance requires more than just design—it demands innovation, cutting-edge technology, and premium materials.
The minimalist open frame is crafted from ovalized 7020 series aerospace aluminum, heat-treated with advanced ShapeLoc technology. Combined with hollow forged caster link tubes, this design minimizes overall weight and reduces the energy required for propulsion. The result? Greater distance, faster speed, and less fatigue.
QUICKIE Nitrum Ultra-Lightweight Wheelchair Features

Active Rigid Option During development of the Nitrum series, we made it our goal to optimize weight savings of each component and to achieve maximum rigidity. Nitrum Active Rigid Frames take this principle to the extreme.Both chairs are based on the same lightweight construction as Nitrum and Nitrum Hybrid, but are characterized by the fixed welded backrest and axle stems which save even more weight, increase frame stiffness, and reduce moving parts.A simple formula Fewer moving parts means:
|
|
|
|
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. |
|
Lifting 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. |

User-Inspired Innovations The first integrated LEDs with a 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?
|
|
Adjustability A perfect fit for EVERY body. Body positioning is crucial for propulsion efficiency. 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. |

Quickie Nitrum Rigid Wheelchair by Sunrise Medical Buyer’s Guide
The Quickie Nitrum Rigid Wheelchair by Sunrise Medical is a high-performance mobility solution engineered for active individuals who require optimal push efficiency and everyday durability. Designed with an emphasis on minimalist architecture, this frame maximizes energy transfer from the user to the wheels, minimizing the effort required for long-distance propulsion. By removing unnecessary joints and folding mechanisms, the structural integrity remains uncompromised over years of heavy use.
Nitrum Minimalist Frame Design and Energy Transfer
The foundational strength of this model lies in its specialized frame design, which utilizes ovalized aerospace-grade aluminum tubing. The unique shape of the tubing increases rigidity along the main stress points while allowing the Nitrum to maintain a sleek, low-profile silhouette. This direct-drive feeling ensures that every ounce of force applied to the handrims translates immediately into forward motion, reducing upper extremity fatigue during daily commutes and navigations.
Ultra-Lightweight Material Engineering
Weight reduction is a critical factor for active users, especially when transferring equipment into vehicles or tackling steep inclines. This ultra-lightweight design is achieved through precise manufacturing techniques and stripped-back hardware options, resulting in a remarkable transport weight. By utilizing advanced materials throughout the backrest, axle plate, and caster housings, the chair offers effortless lifting without sacrificing the stability needed for high-speed tracking.
Customizable Configurations for Optimal Fitting
No two bodies are shaped the same, which is why this model is built to be highly customizable from the initial order to daily fine-tuning. Users can select from a vast array of seat widths, depths, front frame angles, and center-of-gravity settings to match their unique anthropometric measurements. This level of personalized tailoring ensures proper weight distribution across the seating cushion, which is vital for skin protection and keeping an active posture.
Rigid Structural Integrity for Active Lifestyles
Choosing a rigid frame over a traditional folding chair offers substantial benefits in terms of responsiveness and long-term durability. The unified welded structure eliminating moving components under the seat means there is no mechanical play or flexing when traversing uneven sidewalks or cobbles. This stable platform gives the user greater confidence during high-intensity maneuvers, curbside drops, and tight indoor turning radiuses.
Innovative Integrated Lighting and Ergonomic Options
Safety and visibility are enhanced through thoughtful design add-ons, including optional integrated LED lights mounted directly into the caster arms. These low-profile lights illuminate the path ahead in low-light environments without adding bulky aftermarket hardware to the frame. Additionally, the patented backrest angle adjustment system allows for quick modifications while the user remains seated, ensuring continuous comfort throughout changing daily activities.
Quickie Nitrum Rigid Wheelchair by Sunrise Medical Review
