According to the data of the China Bicycle Association, in 2005, the social ownership of a two-wheeled 12 inch e-bike in China was about 23.2 million, and in 2018, it has exceeded 250 million, and two-wheeled 12 inch e-bike has become one of the important travel tools for residents. At the same time, China is the world's largest exporter of two-wheeled 12 inch e-bike, with production and sales accounting for more than 90% of the world.
Which characteristics of 12 inch e-bike are most concerned by users
In terms of 12 inch e-bike selection factors, range, price, product quality, battery type, and design are the top five indicators that consumers are most concerned about.
As a commuting tool, the most basic range of 12 inch e-bike is considered the most important.
At present, the range of 12 inch e-bike usually varies from 40 to 120 kilometers, and the range of 12 inch e-bike is determined by the capacity of the battery pack. By brand new batteries, the range is about 40 km for 48V12A, 70 km for 48V20A and 64V12A, 90 km for 60V20A and 64V20A, and 120 km for 72V20A.
The most important thing about electric bikes is the battery, which not only determines the range, but also the price of the electric bike. There are three main types of batteries for electric bikes: lead-acid batteries, nickel-hydrogen batteries, and lithium-ion batteries, all with different quality, weight, life, and price.
Lead-acid batteries are heavy, slow to recharge, short-lived, and prone to secondary pollution, but they are less expensive, so they still account for a larger market.
Nickel-hydrogen batteries have long cycle life, safe and reliable, maintenance-free, and can be regenerated, but they are costly, expensive, and have low capacity density, memory effect, and are not friendly to the environment.
The lithium-ion battery has the advantages of high bulk energy density and mass-energy density, high operating voltage, long cycle life, environmentally friendly, no memory effect, low self-discharge rate, wide operating temperature range, etc. It is a "green" secondary energy battery and is now commonly used in electric bicycles.
In terms of safety, the traditional lead-acid batteries and nickel-hydrogen batteries, with mature technology and stable process, the battery performance is very stable in the process of use and not easy to cause safety accidents. Lithium-ion batteries, due to their own structure and chemical system instability and other factors, once the collision, extrusion, overcharge, short circuit and other situations, easy to cause fire, explosion, and other safety accidents.
12 inch e-bike is convenient and affordable, fast and energy-saving, and can be a good solution for short-distance travel, flexible shuttle in the streets and alleys, without worrying about traffic jams. In recent years, many cities have started to share electric bikes.
