Based on structure, they are primarily classified into sidecar motorcycles (also known as "side-hacks"), conventional three-wheelers (with one wheel at the front and two at the rear), and reverse trikes (with two wheels at the front and one at the rear). Based on intended use, they can be categorized into vehicles for the elderly (primarily for personal mobility), cargo three-wheelers (primarily for freight transport), and passenger three-wheelers (primarily for carrying passengers). Based on power source, they are classified into internal combustion engine models and electric models.
According to national standards, a three-wheeled moped is defined as a three-wheeled motorcycle with an engine displacement of no more than 50cc and a maximum design speed not exceeding 40 km/h (classified as Category L2). Electric three-wheelers with speeds between 25 km/h and 50 km/h are classified as electric mopeds; they are considered motor vehicles and must display a license plate with white characters on a blue background ("blue plate"). Drivers are required to hold a Class F, E, or D driver's license. These vehicles are designed for single-person use, and carrying passengers is strictly prohibited. Operating a three-wheeled moped requires the appropriate motor vehicle driver's license.
