Check that the charger input plug is connected and plug the charger input plug into the normal power outlet. If the situation remains the same, open the charger shell and observe whether the fuse connection is intact or not.   If there is no open circuit, check whether the input line of the power supply…

For electric vehicles, the electric bicycle charger is an unremarkable accessory. Electric bicycle chargers have fewer faults than batteries and motors that are prone to problems.   When charging, the power indicator light is on, the charge indicator light is orange.   First check that the charger output plug of front wheel electric bike kit…

The frame part is the basic inexpensive electric bike kit of the electric bike, is also the skeleton and the main body of the electric bike. The other parts are also directly or indirectly mounted on the frame. There are many structural forms of the frame parts. But the overall can be divided into two…

If the contact is not firm and the degree of contact is light, the conduction will be poor, which will make the contact part of the line heat, the line loss is large, the output voltage is low, which will affect the power of the motor and reduce the mileage or can't ride normally.  …

The sun is strictly prohibited from exposure to the sun. Batteries for electric bikes should not be close to high temperature heat sources. During high temperature seasons, direct exposure to the sun is strictly prohibited (pay special attention to car storage in summer. Pay attention to good ventilation when charging, no matter electric bike vs…

The first is the drift of the cold and hot state parameters and the decrease of 0.1 v-0.35v in the maximum voltage of the hot state than that of the cold state. The reason for this kind of problem is the improper selection of the electronic components or the inadequate aging conditions. In the drafting…

The main technical parameters of three-stage charger are constant current, maximum voltage, conversion current and floating charge voltage. The highest voltage and the conversion current are two important parameters to decide whether a battery can be adequately charged or overcharged. The constant current value is within a certain range, and it only determines the length…

The over sealing of best all terrain electric bike and the heating phenomenon of the power fuse.   Most of the power boxes used for electric bicycles in the current market are closed. When the battery is charged, especially at the end of charging, it produces a certain amount of hydrogen and a small amount…

¡¡¡¡Controller of 750 watt electric bike is one of the most concerned components in maintenance, and the damage of controller is also common. General controller lead contains several items: power line, motor line, brushless generally have five-core Hall wire, turnstile wire, speed line, brake lamp line, under voltage line, power line, etc. ¡¡¡¡From the appearance,…

¡¡¡¡At present, electric bike motor is usually divided into three types, brushless low speed motor, brushless low speed motor and brushed low speed motor. ¡¡¡¡Brushed high speed motor. High efficiency of motor, strong ability of overloading and climbing, large starting torque, output power after deceleration through gear device with variable speed, noise. ¡¡¡¡Brushless low speed…

All preparations must be made before riding to ensure the safety of riding. To ensure the safety of the users, it is strictly prohibited to get on and off when the motorized bike stays stationary. Power lock switch must be turned off before getting off. When adjusting the height of saddle and handlebar, be careful…

The overcharge should be avoided as far as possible, the parameters of charger should be well matched with the battery, the operation condition of the battery in the high temperature season and the variation of the whole service life should be fully understood.   The storage battery should take cooling measures after heating, wait for…

The majority of Japanese electric bike are driven by shafts for two main reasons: First, Japan legally stipulates that electric bike must output auxiliary electric power according to manpower, so they must measure the pedal force and install a force measuring mechanism on the central axis (sensors, which combine the driving mechanism and the force…

There are 2 lines ( mechanical switch ) , 3 lines of ( Hall switch ) , 2 - wire mechanical switch only on and off states , and the Hall brake of the 3 line judges the power supply first , and then judges the signal . In general, there are 2 kinds of…

At present, the modus operandi of car theft is divided into four types: electric tools, manual tools and techniques for opening locks, handling gangs, etc. The manual tools are mainly used in steel saw, forceps, word steel, cross steel, hammer and so on.   Electric tools generally use portable electric drill, electric cutting machine and…

Fat tire electric bike has become the first choice for ordinary people because of its beautiful, cheap, fast, and low cost and so on, and has been widely used in a short period of time. Due to the influence of law, safety consciousness of traffic participants and other factors, the defects of electric bike affecting…

At present, a large number of anti-theft alarm products for electric bike are on the market. Some of the cars themselves have already installed such products. That make china electric bike price is high. These products emit an alarm sound of 80-120 decibels when the electric bike is touched, moved, and vibrated. It can inform…

Generally speaking, the majority of stolen electric bike occur in the state of parking. Choosing a good parking place and safe parking method is an important means to prevent electric vehicles from being stolen. Here are some suggestions for users.   1, do not use electric bike temporarily, need to park for a period of…
