Not everyone can live without that red mark in the ledger, but we'll help you find out if you might be a candidate. Where I live in Atlanta, the necessity of owning a car is highly subjective. In some areas, it's not possible to get by without a car, as everything is miles away.
A continuously variable transmission (CVT) (also known as a single-speed transmission, stepless transmission, pulley transmission, or, in case of motorcycles, a twist-and-go) is an automatic transmission that can change seamlessly through a continuous range of effective gear ratios.
Automatic transmissions that use gears need to switch between gear positions, while CVT does not. Since power from the engine is continuously fed to the tires, the ride is smoother. With CVT, diameters of the areas where the two pulleys meet the belt can be infinitely varied (Figure 1). Each pulley consists of two conical plates facing each other, which by moving closer or further apart, changes the diameter of the area meeting the belt (Figure 2).
