The imbalance of series battery of fat tire electric bike is a worldwide problem, and there are always “backward” batteries in the process of use. Its reason is various: have production reason, also have the reason of raw material, and

Reason 1: the inner bearing clearance of electric bicycle is large Treatment: replacement of bearings   Reason 2: motor rotor sweep Treatment: repair of stator, fat tire electric bike and rotor Reason 3: magnetic steel loosening Treatment method: rebonded magnetic

If the damage of integrated circuit is detected, it is necessary to replace the integrated circuit. Disassembly integrated circuit When disassembled, heat printed circuit board with flame of wine lamp to form circuit pin pad, move printed circuit board quickly

By measuring the supply voltage or signal voltage of the connecting parts or leads of the controller, we can analyze and determine the fault of the controller. Referring to the main phase check measurement diagram of the brushless controller, a

Recently, some data show that the sales data of electric bicycles in the United States ushered in explosive growth, with an increase of more than 400. Sales as high as 26.3 w, of which 80% of the sales from Chinese

The most important thing to maintain for a foldable electric bike is a battery. It is best to discharge and charge the battery at regular intervals. Usually two or three weeks. This can activate the capacity of the battery, so

First of all, the maintenance of bicycles after rain do not use sewing machine oil. Sewing machine oil is a kind of thin lubricating oil. If it is used on bicycle, it will dilute the original butter in the car

In 90s the manufacturing process in Shanghai represented the highest level in the country, so made in Shanghai represented quality. The electric car industry still has this phenomenon, many folding electric bike are under the banner of Shanghai. The Shanghai

How fast is an electric bike? The dashboard of an electric bike is generally virtual and the speed has been adjusted. At present, the speed of the universal motor is at 32kmg / h, 48v / 350wN, and the special

After charging the lamp, the test instrument is used to detect the data. The voltage of the new battery is not higher than 59.5, and the battery of folding electric bike about half a year is not higher than 58.8,

Now the lead acid battery is generally used, the regular detection of lead acid battery must detect the actual capacity, generally 0.5 c as the standard discharge rate of 2 hours capacity value, if not up to the manufacturer’s prescribed
