Q: Can the battery of electric bike be exposed to the sun for a long time?   A: This is absolutely not possible! Too high temperature will increase the internal pressure of the battery and make the battery lose water, lead to the decline of the battery activity and accelerate the aging of the electrode…

Batteries look rather delicate, but it's important to maintain motors and batteries if you want to extend the life of pure electric bikes.   According to the actual situation to grasp the charging time and frequency, reference peacetime frequency and mileage. When running normally, if the meter indicates red and yellow lights, it should be…

In-30 ¡æ and above-50 ¡æ, electric bike wheel kit and steel rings (wheels) squared without falling off. Both inflatable and non-inflatable tyres must undergo such tests. Any substance has the effect of heat expansion and contraction, if the tire does not control the shrinkage of the material in the manufacturing process, or a large amount…

Is the battery safe?   Leakage, spontaneous combustion, explosion, safety problems become the biggest hidden danger of electric bicycle battery. To this end, the national new energy vehicle demonstration "security mandate", strengthen the monitoring of the working state of power batteries and fuel cells.   Manufacturers have also been strengthening their research on battery safety…

Battery life of electric bicycle is also one of the important parameters to measure the performance of secondary battery. It refers to the time when the battery begins to charge and discharge cycle after adding electrolyte to the end of charge and discharge cycle life (including the time when the battery is in discharge state…

Charge / discharge cycle life is an important parameter to measure the performance of secondary battery of electric bike. To undergo a charge and discharge is called a cycle (or a cycle). Under a certain charge / discharge system, the battery can withstand the charge and discharge times, which is called the charge / discharge…

Additional battery   Series a section with the original battery of the same specifications of the battery, overvoltage, so that the motor over-frequency operation. Note: after the series position is the switch line, keep the voltage of the switch line unchanged so as not to damage other equipment due to the increase of voltage; In…

Electric bike don't work for a long time, and if you don't care for their batteries, when the weather gets warmer and you want to ride out, you'll probably have to pay for a new battery. The core lightweight electric bike kit of electric vehicle is battery. According to the introduction, the battery of electric…

Although e-bikes are now cheaper to charge than traditional fuel vehicles. However, since the e-bikes itself is sold at a high price, and the battery life is relatively short, the replacement battery will also be a huge expense, so the cost obstacle ¡°battery maintenance and maintenance¡± has become a ¡°stop tiger ¡°for the popularization of…

In 2017, China produced 794,000 best electric bike and sold 777,000, accounting for 2.7 percent of the total vehicle output, ranking first in the world for the third year in a row. The technical level has improved significantly, and the mainstay mileage of the mainstream passenger cars has reached more than 300 kilometers, keeping pace…

In all normal conditions of engine, the engine or battery failure will make it difficult to start, or even unable to start. In this case, first of all, to understand the use of starter and battery, in order to roughly determine the fault location.   If the battery has been used for more than one…

We are going through a great energy revolution, underpinned by rapid advances in new energy and information technology, and we have to jump out of electric bike to assess its impact on the economy and society in the future. The development of 700c electric bike kit also needs strong support from the government in terms…

Battery   The battery of best all terrain electric bike mainly has silver glue, lead acid, lithium, nickel hydrogen and so on kind. The capacity and life of the battery determine the cost of riding in the later stages of the electric bike. Battery two parameters, output voltage v to select the standard 12 volts,…

Electric bike occupy small lanes. China is the most populous country. If cars are popularized, it will be a waste of resources. China is the most populous country, if cars become popular, it would be a waste of resources, such as energy, roads (including parking spaces). The electric bike can avoid the above disadvantages.  …

There are many cheap and functional electric bike conversion kit, as follows: Electric bike windproof Before the windbreak, many electric bike owners basically rely on anti-clothing to protect against the cold of the wind. The reverse approach can only provide the slightest protection, but also brings a significant increase in the dangers of riding, not…

There are many charger internal circuits, input and output lines aging, resulting, sometimes can be filled, sometimes cannot flush. It seriously affects the battery, or the circuit failure in the charging process, causing the drum to fill. If this is the case, please replace the high quality charger of cheap electric bike and use it…

As a tool for convenient travel, electric bikes have increasingly occupied the market share, becoming the preferred vehicle for more and more people.
