Sub 4 kg - Guaranteed, no hidden extras...

Your made-to-measure Tiga Sub4 wheelchair frame is guaranteed to be under 4 kg, we’ll even write the exact weight on your certified frame. This includes all standard components such as; compact wheel locks, carbon fibre side guards with fender, castors, carbon fibre footrest cover and upholstery. The rear wheels and cushion are not included as these are easily removed for transportation.
The lighter the wheelchair, the less energy you need to push – it’s that simple.

We understand that a small weight saving can make getting in and out of the car that little bit easier, so imagine what a massive weight saving can do for you! The Sub4 glides effortlessly due to the lightweight and rigid frame, but don’t think we've compromised on quality.  The Sub4 boasts all the same reliability features as the TIGA, and with the frame being very similar in design and materials, you can be sure the Sub4 isn’t just super light, but it’s super strong too!

The stiff, robust made-to-measure frame and footrest is hand built and designed to your individual requirements. Every tube has been reviewed and analyzed to ensure any excess weight is removed and the reliability that you've come to expect from an RGK wheelchair is maintained. The same has been done for the parts too. The caster wheelchair, sideguards, brakes and fasters have also been reviewed and analyzed to remove any excess weight - without compromising function. So the standard ‘on the road’ specification includes all you need to achieve that under 4 kg weight ... with no hidden extras.
