RGK Octane Sub4

The RGK Octane Sub4 provides a new level of durability. Sub4 technology combines with a hand-crafted made to measure titanium grade 9 frame, resulting in an ultra lightweight and rigid wheelchair that is perfectly designed to fit you and your lifestyle.

Product Description

A classic design is redefined by RGK's Sub4 technology to create the ultra-lightweight Octane Sub4 wheelchair, guaranteed will weigh less than 4 kilograms. This technology involves utilizing advanced materials and design techniques to achieve a significant reduction in the weight of the wheelchair, enhancing its performance, durability and usability.

Titanium has all of the positives of aluminium with the additional bonus of a natural shock absorption by the material itself and a greater ability to bend than steel or aluminium. As a consequence, the Octane Sub4 makes for an extremely smooth ride and it's highly durable.

Numerous individual measurements are taken of the user to ensure the Octane Sub4 fits their individual requirements, providing a personalized fit and optimal comfort. Additionally, RGK provide a full range of ergonomic backrests and seats to ensure comfort, pelvic positioning and balance. And there is a wide range of other accessories available such as wheel locks, side guards, push handles and armrests.

The heaviest part is an incredible 3.6kg. This light weight makes everyday travel that much easier with the Octane FX but it has the potential to rise to 12kg depending on additional options, excluding third party wheelchair add-ons. With wheels, the total weight of the wheelchair is 5.5kg rising to a maximum of 15kg, again depending in additional options but not including third party add-ons.

The Octane Sub4 is as stylish as it is functional, featuring a newly designed castor arm and carbon fibre sideguards, enhancing the wheelchair experience with style and performance. RGK's Airtech Technology system provides for a tension adjustable backrest and centre pad, including mesh cover panels, for better support and positioning. It's a breathable material designed to keep you cool.

Our Verdict

The Octane Sub4 is a good-looking well-fitted chair with a nice set of features buts what stands out is the weight. It's significantly lighter than the Octane but you might want to explore the option of a folding version in the Octane FX, or even the Veypr Sub4, which comes with the RGK sub 4kg transportable weight guarantee and made of carbon fibre.

Active wheelchairs are built to order following an assessment with one of our Prescriptive Assessors. They are available with a wide range of customisation options, from wheels to seating to style upgrades, and these can affect the price - our Prescriptive Assessors will run through all the options at your assessment. As a general guideline, we find most people will spend around an additional £500 - £1,500 on customisation options on active wheelchairs; however it is possible to get a fully functioning and desirable chair at the base price!

People purchasing active wheelchairs will normally qualify for zero-rated VAT. If the person using the wheelchair has a permanent disability, terminal illness or chronic sickness then they will be eligible for 0% VAT. Our Prescriptive Assessors will be able to answer any questions you may have about VAT.
