Under the general daily demand and routine use, the service life of electric vehicles will exceed 5 years, and some people who can maintain and use them moderately will use electric vehicles with longer service life, reaching 10 years.
The primary stage of electric bicycle is also called the early experimental production stage of electric bicycle, from 1995 to 1999. At present, the key technologies of electric bicycle's motor, battery, charger and controller are explored and studied.
In terms of R&D and production, it is mainly based on the spontaneous information collection, tracking technology, market observation and small-scale market trial release of production enterprises, which also makes electric bicycles enter the consumer's field of vision and gradually be recognized and accepted by consumers.
From a technical point of view, the early electric bicycles can only travel about 30 kilometers at a time with a new battery, which has short battery life, poor climbing ability and easy wear and tear. The motor is also a brush and toothless motor. However, the accumulation during this period laid the foundation for industrialization in terms of talents, technology and product research and development.
