RGK Octane Sub 4 ultra lightweight rigid wheelchair


The first made to measure titanium wheelchair guaranteed under 4kg.

Resulting, in an ultra-lightweight and rigid wheelchair that is perfectly designed to fit you and your lifestyle.

Key features 

No corrosion – Titanium will not rust and is very resistant to corrosion and salt water. Perfect for adventures out and about.

Smooth ride – The frame has a natural in-built shock absorption to soak up road vibration, which means that it will deliver a super-smooth and comfortable ride quality like no other.

Durability – A titanium frame has a far greater ability to bend without breaking, elongating by up to 25% compared to around 15% for steel and 8% for aluminium.

Strength to weight ratio – Strong as steel but 45% lighter, titanium has the highest strength-to-weight ratio out of all the known metals.
