High Quality Content by WIKIPEDIA articles! A kick scooter or push scooter, originally scooter, is a human-powered vehicle with a handlebar, deck and wheels that is propelled by a rider pushing off the ground. The most common scooters today have two hard small wheels, are made primarily of aluminium and fold for convenience. Some kick scooters that are made for younger children have 3 or 4 wheels and are made of plastic or do not fold. High performance racing scooters made for adults resemble the old "penny-farthing" with a much larger wheel in front.
