I. Background of Electric Scooters, mobility Scooters, and Electric scooters
   The development of electric scooters, mobility scooters and power-assisted vehicles has effectively addressed urban traffic problems and demands.
▲ Congestion and convenience demands: Urban traffic congestion is becoming increasingly severe, and people urgently need more flexible and convenient means of transportation to shorten their commuting time. Electric scooters and mobility scooters are small in size and flexible in operation. They can easily move through narrow streets and crowds, effectively avoiding congested sections and meeting people's needs for short-distance travel in cities.
▲ The pain point of the "last mile" : Public transportation has an advantage in solving long-distance travel, but the connection problem of the "last mile" has always existed. Electric scooters, mobility scooters and electric scooters can precisely fill this gap, making it convenient for people to quickly reach their destinations from bus stops, subway stations, etc.
Technological progress and innovation
▲ Battery technology innovation: The continuous improvement of battery energy density has increased the driving range of electric scooters, mobility scooters and electric scooters. The wide application of lithium-ion batteries not only enhances the battery life but also reduces the charging time and increases the practicality of the products.
▲ The integration of intelligent technologies: The development of intelligent technologies has brought more functions to electric scooters and commuter vehicles. If equipped with functions such as Bluetooth connection, GPS positioning, and intelligent speed limit, vehicle monitoring and anti-theft alarm can be achieved through the mobile phone APP, which enhances the user experience and safety.

Enhancement of environmental awareness
▲ The concept of green travel: With the enhancement of environmental awareness, people are increasingly inclined to choose low-carbon and environmentally friendly travel methods. Electric scooters and mobility scooters are powered by electricity, featuring zero emissions and low noise, being environmentally friendly and in line with the trend of green travel. They are favored by environmentalists and people who pursue a healthy lifestyle.
▲ Policy promotion: The government has introduced a series of policies to encourage green travel in order to reduce carbon emissions and improve the urban environment. Some cities have provided dedicated lanes for electric scooters and commuter vehicles or allowed their passage in specific areas, creating a favorable policy environment for their development.
   New energy lithium batteries, with their advantages of high energy density, long cycle life and environmental friendliness, have become the preferred solution for electric scooters, commuter vehicles and power-assisted vehicles. This solution is designed to meet the application requirements of lithium batteries in electric scooters, commuter vehicles and power-assisted vehicles, ensuring that lithium batteries can provide safe, efficient and customized power solutions in special fields.
