The Wizz is a novel ultralight (8kg) electric walker with a unique seat height adjustment system that can be easily shifted from seating to near standing height when 'whizzing' around. It is easy to use, safe, and effective even in crowded areas due to its agility and small footprint. Ideally suited for use in a work or office environment as the standing height aids personal interaction. If the user has a walking problem but is not physically restricted to a wheelchair, the Wizz can be used in the home to allow normal independent access around the house. It is also a valuable support for rehabilitation as low-stress walking reduces the recovery time from leg injury or trauma.
