twowheelers

Twowheelers, or two-wheeled vehicles, are vehicles that use exactly two wheels for propulsion and balance. The term is commonly used to describe a broad category of personal transport that includes both non-motorized and motorized machines. In many markets, two-wheeler classification encompasses bicycles as well as motorcycles, scooters, mopeds, and electric two-wheelers.

Non-motorized two-wheelers include bicycles, which rely on human pedaling power and balance. Motorized two-wheelers encompass motorcycles (internal combustion engines with varied power and configurations), scooters (often with automatic transmission and a step-through frame), and mopeds (lightly powered vehicles with limited top speed). Electric two-wheelers include electric bicycles (e-bikes), electric scooters, and electric motorcycles, which use electric motors powered by batteries.

Two-wheelers are common for urban commuting due to compact size, low operating costs, and high energy efficiency. They can reduce traffic congestion and parking demand but raise safety concerns. Licensing, registration, helmet and protective gear requirements, and speed or power limits vary by jurisdiction.

Market trends include growth in e-bikes and e-scooters as part of micromobility initiatives, along with continued development of lightweight, efficient engines and battery technologies. Environmental impacts depend on energy source and usage patterns; two-wheelers generally offer lower per-passenger emissions than cars, particularly when powered by electricity from low-carbon grids.
