Kick scooter

A kick scooter, push scooter or scooter is a human-powered land 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.

Models and history

Early scooters

Primitive scooters have been hand-made in industrial urban areas for at least 100 years. One common homemade version is made by attaching roller skate wheel sets to a board with some kind of handle, usually an old box. You can lean to turn, or by a second board connected by a crude pivot. The construction was all-wooden, with 3–4 inch (75–100 mm) wheels with steel ball bearings. An additional advantage of this construction was loud noise, just like from a "real" vehicle. An alternative construction consists of one steel clamp–on roller skate divided into front and rear parts and attached to a wood beam.
