Abstract

A scooter comprising an elongated steering column, a steering system, and a braking system is disclosed and claimed. The steering system allows the elongated steering column to rotate about the longitudinal axis and to hinge in a vertical plane relative to the scooter body. The braking system relies upon contact between a braking arm and the crown of the rear wheel. Such a braking system allows the rider to regulate the amount of braking.
