Description

Technical Field

[0002] An electric tricycle is a three-wheeled transport vehicle that is powered by a battery and driven by an electric motor and is used to transport goods or people. With its strong applicability, maneuverability, simple maintenance, easy repair, and low price, the electric tricycle can flexibly travel through narrow roads. The electric tricycle has a reverse switch that can easily realize the reverse and forward driving functions, which is very practical in narrow alleys and lanes. It is very convenient for driving and parking, and is widely used in short-distance transportation fields such as families, urban and rural areas, individual rentals, factory areas, mining areas, sanitation, and community cleaning.
