Electric tricycles - colloquially known as "sanbengzi" - are three-wheeled transport vehicles powered by electric motors and batteries. Classified as motor vehicles, they are widely used for cargo transport, passenger transport, and specialized operations.
Core Definition and Composition
* Basic Definition: Features a three-wheeled structure and electric drive; includes a reverse gear function; suitable for short-distance transport on narrow roads.
* Core Components: Frame, battery (lead-acid or lithium-ion), motor (brushed or brushless), controller, and charger.
* System Composition: Electrical system (motor, battery, controller, etc.), control system (speed regulation, braking), vehicle body components (frame, rear axle, etc.), and onboard accessories.
Main Classifications
* By Purpose: Cargo (freight hauling, sanitation), Passenger (mobility for the elderly, shuttle services), Specialized (logistics, advertising, disability assistance).
* By Motor Type: Brushed electric tricycles (low cost), Brushless electric tricycles (high efficiency, long lifespan).
* By Structure: Side-wheel motor type (lightweight, for household use), Mid-mounted axle type (stable load-bearing, primarily for cargo transport).
