Sponsors

DNM Suspension have kindly provided us with the 4 independent suspension systems used on the wheelchair for free. The product is their DV-22 Torch Suspension, and is designed for mountain bicycles.
Technology Assisting Disability WA Inc have been a great help throughout the design and implementation of this wheelchair. They have provided us with product samples for trial on numerous occasions, and given us much feedback on practical wheelchair design.
