A Three-Wheel Truck (also known as a cargo tricycle or motorized three-wheeler) is a compact transport vehicle designed for carrying goods over short and medium distances, especially in urban, peri-urban, and rural areas. It has three wheels—one at the front for steering and two at the rear for load support and stability. The vehicle typically includes an engine (petrol, diesel, or electric), a transmission system, a driver’s seat or cabin, handlebars or a steering wheel, a rear cargo bed or box, suspension system, and braking system.

In operation, the engine produces power which is transmitted through the gearbox and drivetrain to the rear wheels, causing the vehicle to move. The driver controls direction using handlebars or a steering wheel, while speed is managed using the throttle, clutch (for manual models), and brakes. Goods are loaded onto the rear cargo platform, which is built to carry moderate loads efficiently. Some models are equipped with a tipping mechanism to make unloading easier. Due to its small size and three-wheel design, the vehicle can navigate narrow roads and crowded areas with ease. Three-wheel trucks are widely used for local deliveries, small business transport, and agricultural produce distribution because they are economical, fuel-efficient, and easy to maintain.
