Introducing the Rogue2
We’re excited to announce that the Ki Mobility Rogue2 Ultra-Lightweight fixed-frame manual wheelchair is in stock at Allied Medical. The Rogue2 replaces the long-standing Rogue 10 model and brings significant improvements in strength, adjustability and propulsion efficiency for Ultra-Lightweight Wheelchair users here in New Zealand.
At the heart of the Rogue2 is its oversized, thin-wall 7005 aluminium frame — a design chosen to deliver exceptional strength-to-weight performance without compromising durability.
Read on to learn more about what makes the Rogue2 stand out in the market and understand the myths and facts when comparing Aluminium vs Titanium Frames in Ultra-Lightweight Wheelchairs.
Myths vs Facts: Aluminium vs Titanium in Ultra-Lightweight Frames
Myth 1: “Titanium frames are always lighter than aluminium frames.”
Fact: Rogue2 achieves ultra-light weight using thin-wall 7005 aluminium with an oversized tube diameter. This reduces material mass while maintaining — and often improving — structural strength compared with smaller-diameter tubes of other alloys.
Why Oversized 7005 Aluminium Works
- Larger tube diameters increase stiffness even with thinner walls — reducing weight.
- 7005 aluminium is a heat-treatable alloy often used in high-performance sports frames.
- When engineered correctly, it provides excellent fatigue resistance and reliable longevity.
- The Rogue2’s design can match or beat the mass of some titanium frames, while remaining more cost-effective and more serviceable.
Myth 2: “Aluminium frames crack sooner than titanium.”
Fact: Longevity depends on design, heat treatment, load paths, and stress management — not just material. Rogue2’s frame geometry and thin-wall 7005 construction are engineered to avoid stress risers and deliver reliable long-term performance.
Myth 3: “Titanium gives a better ride quality.”
Fact: Ride quality is a system property — influenced by wheels, tyres, geometry, seating and configuration. The Rogue2’s stiffness and layout are tuned for predictable handling and efficient propulsion, not unnecessary flex.
Practical Advantages of the Rogue2
- High strength-to-weight efficiency from modern aluminium engineering
- Easier and more affordable servicing compared with custom titanium builds
- Replacement parts and repairs are more widely accessible
- Wide adjustment range for clinical setup needs
Titanium vs Aluminium: Clearing Up the Misconceptions
- Corrosion: High-quality aluminium alloys are finished with protective coatings. Even when scratched, aluminium oxidises into a protective layer far more stable than materials like magnesium.
- Premium status: “Premium” performance is driven by engineering and fit-for-purpose design — not just material choice.
- Noise/harshness: Most noise or harshness comes from components (bearings, tyres, assembly) rather than frame alloy.
Summary: Choosing Between Titanium and 7005 Aluminium
- Frame performance is dominated by geometry, design and configuration — not material alone.
- The Rogue2’s thin-wall 7005 + oversized tubing delivers low mass without sacrificing stiffness.
- Frame weights differ by grams, but accessories can add kilograms — wheels, tyres, guards, armrests.
- Key decision factors include propulsion efficiency, centre of gravity setup, adjustability, long-term serviceability and real-world durability.
Key New Rogue2 Features
Wing Design |
 |
| The wings are designed to get you as close as possible to where you’re going and what you need. Available with an optimised position to minimise the chairs footprint or an Expanded position that maximises stability. The intuitive caster angle adjustment system makes it easy to get perfect alignment at any seat angle, while the corrosion resistant components protect your chair from the elements. | |
Relax Positions |
 |
| Go from your selected back angle to a +4° or +9° relax position providing just enough recline to adjust clothing or simply relax. Adjusting the backrest has never been easier. Using one tool and no disassembly, change the backrest angle with the rider in the chair. Simply insert your allen key and rotate. | |
Lightest-in-Class |
 |
| New design, effortless adjustments, enhanced strength and the durability expected from the most seasoned riders - with NO change to weight. The Rogue2 has a transport weight of only 4.8 kg making it easy to take from place to place. |
Available Now
We hold stock of Rogue2 ULW fixed-frame wheelchairs in New Zealand, ready for fast trials. As the Rogue2 is highly adjustable we can normally leave trial chairs in situ for purchase as opposed to ordering in from the United States once the trial phase has been completed too. In the event that the chair does need to be ordered from the US, we are able to land the stock in only 3 weeks.
