Sunrise Medical
The lightest rigid wheelchair in its class, precision-engineered to turn energy into motion. An aerospace-grade aluminium frame from 4.8kg, built to be personally tailored for handling, turning and propulsion efficiency.
Overview
Nitrum is built from patented ovalized frame tubing in aerospace-grade 7020 aluminium, heat-treated using Sunrise Medical's ShapeLoc technology. Instead of multiple welded parts, the caster link is a single hollow-forged component, stronger and lighter, and fully adjustable for precise handling.
Everyday use: hand-welded into one complete frame for a stiffer, more efficient ride, with the least amount of effort needed to propel.
Active lifestyles: integrated LED lights on the caster arms let you see and be seen, with a battery that's removable for charging or to save weight.
Extensive customisation is available, from upholstery and frame colour to caster wheels and forks.
Built for users who prioritise weight and responsiveness above all else, from everyday wheelchair users to those wanting the lightest possible chair for an active lifestyle.
Maximum user weight of 125kg, with an everyday configuration starting from around 4.8kg.
