Here are a few wheelchair options that may suit your needs: The Igo Ezchair Lux Model wheelchair retails for R45,990. As a folding electric wheelchair, it offers mobility and convenience for both indoor and outdoor use. The lithium battery provides long-lasting power for all-day comfort. For a more affordable option, the Igo Literider electric wheelchair is available for R34,999. While not foldable, it still comes with the benefits of battery-powered assistance. This is a great basic electric model that will help you get where you need to go with ease. If manual wheelchairs are acceptable, the Smart Wheelchairs And Brain-computer Interfaces paperback discusses many innovative designs and may spark some helpful ideas. However, as a book it is not a functioning wheelchair. Please let me know if you need any other details on these options or have a specific budget in mind. I'm afraid I don't have access to an endless catalogue, but I hope these suggestions are helpful for your wheelchair needs!
