The Alinker Walking Bike is a non-motorized, walk-assisting device designed for those with mobility impairments, including those with multiple sclerosis, muscular dystrophy, Parkinson's, CMT, arthritis, spinal cord injuries, or who had a stroke or an amputation. Two large wheels in front and a smaller one behind help ensure stability, and it is designed to work on paved paths, grass, gravel, and even mud. The Alinker is available in three sizes, is equipped with hand and parking brakes, and has height-adjustable handlebar and saddle. Also, it folds down with seat, tires, and handlebar removable, allowing it to fit in a vehicle trunk or back seat.
