Product Schematics

Technical Support

Simple assembly instructions on paper and video are provided with each order for the distributing organization to use. Each RoughRider chair comes with a 60-page User Manual which gives instructions on assembly, adjustment, and use. These instructions are for the wheelchair provider and for the wheelchair rider. Whirlwind assists with capacity building for local professionals and paraprofessionals in order to establish and maintain a sustainable infrastructure for wheelchair services such as assessment, fitting, rider training, and repair.

Replacement Components

Whirlwind is expanding its franchise program  with the development of Wheelchair Provision and Assembly Centers (WPACs), which will serve as local hubs for continuous in-person service for the RoughRider and its users.

Lifecycle

Although life cycle is not indicated, users have been know to have the chair over 20 years.

Manufacturer Specified Performance Parameters

Works on rough terrain; easily repairable; composed of readily available components for simple repair around the world; adjustable to accommodate individual needs; maximum load 100kg; affordable in developing country contexts.

Vetted Performance Status

Whirlwind conducted tests  found the RoughRider to pass the ISO Standard tests, including the minimum 200,000 cycles on the two-drum durability tests P10.4, and 6,666 cycle horizontal 50 mm (2 inch) drop test P10.5. Passing the static strength and impact tests is a good indicator of a chair's ability to also pass the ISO Standard durability tests.

Safety

A wheelchair that is not properly fit to the needs of an individual user can result in discomfort or injury (such as scoliosis or pressure sores) due to insufficient support or improper cushioning. There is also a risk of tipping while using a wheelchair.
