The Cougar S8 Power Assisted Handcycle is a quick release wheelchair attachment designed to fit the majority of rigid frame wheelchairs and will transform your wheelchair into a brilliant sleek and sporty handcycle. Coyote S8 can be connected to most rigid wheelchairs via a docking system that is permanently mounted under the wheelchair. Once connected it takes only seconds to dock on. The rear of the docking system is bolted to either the axle or a bar going across the back of the chair. The front of the docking system is bolted to the bar underneath the seat canvas towards the front of the seat.
