The company behind the Segway Human Transporter has agreed to recall the motorized scooters because riders have been injured falling off when its batteries are low. “The Consumer Product Safety Commission announced the recall Friday, saying that three people had been injured. One suffered a head wound and needed stitches,” reports AP. “The recall involves about 6,000 of the single-rider, two-wheeled scooters that can travel up to 12 mph. The scooter uses gyroscopes to keep it upright, making it less likely to fall or be knocked over.” The Segway was touted by celebrity investors such as Apple CEO Steve Jobs and venture capitalist John Doerr as having the potential to transform human mobility, notes the Washington Post.
