RGK Tiga Sub4 Ultralight Rigid Manual Wheelchair

The RGK Tiga Sub4 is a rigid manual wheelchair designed around one idea: every gram matters. RGK built its frame from aeronautical-grade aluminum and states that it weighs less than 4 kg (about 8.8 lbs), measured without the wheels and cushion. For active users, a lighter frame means less effort with every push and less to lift in and out of a car.

Why choose the RGK Tiga Sub4 ultralight rigid wheelchair?

• Very light frame: RGK states the frame weighs under 4 kg, excluding wheels and cushion.
• Aeronautical aluminum construction: a strong, light material that keeps the chair responsive.
• Rigid design: a rigid frame transfers more of each push into forward motion than a folding frame.
• Built around the user: the Tiga Sub4 is a custom wheelchair, configured to fit the person who will use it.
• Smooth handling: designed for confident, comfortable driving.

What does “under 4 kg” include?

The figure refers to the frame only. The finished chair weighs more once the wheels, cushion, and any extras are added, and the total depends on the configuration you choose. Contact us for the weight of a specific build.

Who is it for?

The Tiga Sub4 suits experienced and active wheelchair users who want a custom-fitted, lightweight chair for daily use. Because it’s made to order, fit matters: seat width, seat depth, and back height should be chosen with care.

How to choose a custom rigid wheelchair

1. Measurements: the right seat width, depth, and back height affect comfort and posture.
2. How you’ll use it: daily use, sport, or travel can change the best setup.
3. Cushion and wheels: these change the final weight and ride.
4. Transport: think about how you’ll load the chair into a vehicle.
