Scooter (motorcycle) in the context of "Small engine"

A headlamp is a lamp attached to the front of a vehicle to illuminate the road ahead. Headlamps are also often called headlights, but in the most precise usage, headlamp is the term for the device itself and headlight is the term for the beam of light produced and distributed by the device.

Headlamp performance has steadily improved throughout the automobile age, spurred by the great disparity between daytime and nighttime traffic fatalities: the US National Highway Traffic Safety Administration states that nearly half of all traffic-related fatalities occur in the dark, despite only 25% of traffic travelling during darkness.

Mod, from the word modernist, is a subculture that began in late 1950s London and spread throughout Great Britain, eventually influencing fashions and trends in other countries. It continues today on a smaller scale. Focused on music and fashion, the subculture has its roots in a small group of stylish London-based young men and women in the late 1950s who were termed modernists because they listened to modern jazz.

Elements of the mod subculture include fashion (often tailor-made suits) and music (including soul, rhythm and blues and ska, but mainly jazz). They rode motor scooters, usually Lambrettas or Vespas. In the mid-1960s, members of the subculture listened to pop groups with rhythm and blues (R&B) influences, such as the Who and Small Faces. The original mod scene was associated with amphetamine-fuelled all-night jazz dancing at clubs.

In the market, there is a wide variety of types of motorcycles, each with unique characteristics and features. Models vary according to the specific needs of each user, such as standard, cruiser, touring, sports, off-road, dual-purpose, scooters, etc. Often, some hybrid types like sport touring are considered as an additional category.

There is no universal system for classifying all types of motorcycles. However, some authors argue that there are generally six categories recognized by most motorcycle manufacturers and organizations, making clear distinctions between these six main types and other motorcycles. For example, scooters, mopeds, underbones, minibikes, pocket bikes, electric bikes such as surrons or talarias or even skark vargs, and three-wheeled motorcycles are often excluded from the main categories within these classifications, but other classification schemes may also include these types of motorcycles.

Electric motorcycles and scooters are plug-in electric vehicles with two or three wheels. Power is supplied by a rechargeable battery that drives one or more electric motors. Electric scooters are distinguished from motorcycles by having a step-through frame, instead of being straddled. Electric bicycles are similar vehicles, distinguished by retaining the ability to be propelled by the rider pedaling in addition to battery propulsion.

Electric scooters with the rider standing are known as escooters.
