The kick scooter or push scooter resembles nothing so much as a skateboard with a bicycle handles. The user grasps the handles and pushes forward with one foot to gain momentum. Scooters were originally made by attaching roller skates to a flat board and adding some sort of handle. The user steered by leaning to one side or the other. In the late 1990s, Wim Ouboter of Switzerland created the Aluminum Scooter, which is the design we think of now when we picture kick scooters. It has a narrower base than previous scooters and conveniently folds away for storage. While the scooter is still primarily a child's toy, it is also now used in Extreme Sports competitions, where young adults perform tricks and stunts.
