The Razor scooter is a compact folding Kick scooter invented by Micro Mobility Systems and manufactured by JD Corporation. The first Razor scooter was distributed by The Sharper Image in 1999 and became extremely popular around 2000. Today, The Razor Scooter is manufactured by Razor USA, based in Cerritos, California. Besides its primary use as a toy for the young, it is also used for sports and utility purposes.
The basic scooter design consists of an aluminum frame, 98 mm polyurethane wheels, and a hinged fender over the rear wheel, which is pushed down by the foot to act as a spoon brake. The handlebar and headtube fold when a quick release latch is opened, allowing for easy carriage and storage.

Freestyle scootering is a growing sport. Due to the rough demands of trick riding, people often reinforce the scooter to withstand impacts and high force. In 2004, Razor released the Pro model scooter, modeled after the discontinued B model scooter. This scooter was preferred by most freestyle riders between the mid 2000s to 2009 because of its bigger size and added strength. However, most freestyle scooter riders today use aftermarket parts to build custom scooters from companies such as Phoenix, Havoc, Lucky, and Madd Gear. The Pro Model improved upon the B model to become the company's strongest freestyle scooter. Razor also have the A series. A2 and A3 have a manual bar at the back, which serious riders disdain and remove. Razor has an Ultra Pro scooter as well, Released in 2009 with its 1-piece design built for strength and durability.
Analysis of toy related injuries  between 1990 and 2011 showed a sharp increase in injuries related to ride-on toys in the years 1999 to 2002, corresponding to introduction of the Razor scooter.
