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!

Frequently Asked Questions

The total width of your wheelchair can be found in the user manual (or in the ordering documentation of your wheelchair). What is important to know when it comes to manual wheelchairs is if you have a camber, the overall width increases rapidly. For example, a wheelchair with 6 degrees camber and 24 "wheels, becomes 80 mm wider than a chair with 0 degrees camber.

Please consult your user manual for more information on setting changes for your wheelchair.

Yes, our Built-4-Me team can help you achieve requirements that go above and beyond what you would find on the typical product order form. They'll make every effort to provide you with the most suitable solution to your request. 

We'd recommend that your wheelchair is serviced by an authorised Sunrise Medical dealership every year. For your safety, some elements of your wheelchair should be checked regularly. Please refer to your user manual for more information.

Ultra-lightweight wheelchairs tend to be made of areospace-grade aluminum or carbon fibre, so they're stronger whilst not compromising the weight of the wheelchair. More durable, ultra-lightweight wheelchairs are custom-built to your needs and are highly customisable with a wealth of features and style options. QUICKIE's range of ultra-lightweight wheelchairs also employ a range of unique patented features to further strengthen the frame whilst minimising weight (such as ShapeLoc Technology on the Xenon series or X-Braid Technology on the Krypton).
