With the increasing prosperity of the electric bicycle market and the continuous improvement of consumers' performance requirements, the driving distance has become one of the important 

indicators to measure the performance of electric bicycles. In this paper, from the aspects of electric bicycle battery technology, motor efficiency, vehicle design and so on, the influencing factors 

of electric bicycle mileage are deeply discussed, and the corresponding optimization measures are proposed.

As an environmentally friendly and convenient means of transportation, electric bicycles have been widely welcomed in the market in recent years. However, with the improvement of consumers' 

performance requirements for electric bicycles, driving range has become one of the important factors for consumers to choose electric bicycles. Therefore, how to improve the mileage of electric 

bicycles has become an urgent problem for the electric bicycle industry.

Factors affecting mileage of electric bicycles

Battery technology

The battery is one of the key factors in the range of an e-bike. The energy density, capacity and life of the battery will directly affect the mileage of the electric bicycle. At present, the mainstream 

electric bicycle batteries on the market mainly include lead-acid batteries, nickel-metal hydride batteries and lithium-ion batteries. Among them, lithium-ion batteries have the advantages of high 

energy density, low self-discharge rate and long life, so they have become the mainstream choice of electric bicycle batteries.

Motor efficiency

The efficiency of the motor is also an important factor affecting the mileage of the electric bicycle. The more efficient the motor, the farther it can travel on the same charge. Therefore, the motor 

design of the small island electric bicycle should focus on improving the efficiency of the motor and reducing the loss of energy.

Vehicle design

Vehicle design is also an important factor affecting the range of electric bicycles. Body weight, tire friction coefficient, vehicle structure, etc., will affect the mileage of electric bicycles. For example, 

excessive body weight will increase the energy consumption of electric bicycles, thus reducing the driving range; Optimizing the vehicle structure and reducing air resistance can also effectively 

improve the mileage of electric bicycles.

Measures to increase the range of electric bicycles

Optimized battery technology

For battery technology, battery materials with higher energy density can be used to improve battery capacity and energy density; At the same time, the battery management system 

is optimized to improve the utilization rate and life of the battery, thus extending the mileage of the electric bicycle.

Improve motor efficiency

Improving the motor efficiency is an effective way to increase the mileage of electric bicycles. Through the use of advanced motor design technology, reduce the energy loss inside the motor, 

improve the conversion efficiency of the motor; At the same time, the motor and battery are reasonably matched to ensure that the motor runs in the best working state, thereby further

 improving the mileage of the electric bicycle.

Optimized vehicle design

In terms of vehicle design, the mileage of electric bicycles can be improved by reducing the weight of the body, optimizing the structure of the vehicle, and reducing the air resistance. For example, 

the use of lightweight materials to manufacture the body, reducing unnecessary decorations and accessories; Optimize wheel design to reduce the friction coefficient between tire and ground; 

Design reasonable body shape, reduce air resistance, etc.

In summary, the mileage of electric bicycles is affected by many factors such as battery technology, motor efficiency, and vehicle design. In order to improve the driving range of electric bicycles, 

it is necessary to continuously optimize the performance of battery technology, improve the efficiency of the motor, and optimize the vehicle design. At the same time, the government and enterprises 

should also increase investment to promote the innovative development of the electric bicycle industry, and provide consumers with more high-quality, environmentally friendly and efficient electric 

bicycle products.

With the continuous progress of science and technology and the continuous development of the market, Tianjin electric vehicle manufacturers believe that the mileage of electric bicycles will be 

further improved in the future, bringing more convenient and environmentally friendly choices for people's travel.
