NEXT Mobility has a power-assisted manual chair that provides resistance free assistance for the user. The Tailwind Power Package, which is fitted to their RTm lightweight manual chair, consists of a controller, lightweight battery, motors, and quick-release wheels with touch sensitive hand rims. The controller senses inputs from the hand rims about 200 times per second and will provide power assistance when it senses that the user will have difficulty, such as when the user is going uphill or traversing rough terrain. It will even assist in keeping the chair tracking correctly if it senses that one wheel is slipping and could cause the chair to travel off the intended direction. The battery provides up to 9 miles of sustained assistance and can be charged in less than 4 hours. This should provide another viable option for those needing a powered assisted manual chair. Check out the clip to see it in action.
