Depending on the design of the vehicle, motorized trikes may be categorized as motorcycles, motor
Motorcycles with sidecars are not usually considered tricycles. It can be harder to categorize three-wheeled automobiles. While some early prototype automobiles were
A motorized tricycle's wheels may be arranged in either configuration: delta or tadpole. A delta trike has one wheel in front and two in back, and the tadpole trike has two wheels in front and one in back. Occasionally, rear wheel steering is used, although this increases the turning circle and can affect handling (the geometry is similar to a regular trike operating in reverse, but with a steering damper added).
Tadpoles are more stable under braking and more likely to slide instead of roll; front braking hard on a delta requires the vehicle to steer almost straight to avoid tipping. The balance of friction patches and rolling resistance also means that tadpoles tend to oversteer and deltas understeer.
Motor trikes are attractive for those with mobility or balance problems.
Under some local regulations, while riding a three-wheeled vehicle, it may be possible to carry multiple passengers with a motorcycle driving license, to ride a motorcycle-style vehicle with a car license, or to avoid motorcycle helmet use regulations.
These machines are generally custom-built. A common arrangement is to fit
Mass-manufactured motor tricycles include the
