Cause of failure 4: the drive system of electric mountain bike rub resistance is too big. The elimination method: 1 adjusts the relevant parts of the transmission system so that the flywheel, sprocket and chain are on the same plane to eliminate the axial run out of the sprocket. Trouble cause 5: wheel soft. Troubleshooting…

When you ride an electric mountain bike normally, if you feel the car heavy, electric, pedaling, and slow, we call these phenomena hard riding. As soon as you get more and more tired on an electric bike, it is likely that there are seven reasons for this: Cause of failure 1: insufficient air or jogging…

The first step is to test the batteries of china electric bike. Electric car battery is the chief culprit for the continuation of the kilometer. The main reasons for the short run of electric bike are the serious vulcanization and loss of water, the short circuit and open circuit of the electrode plate, the broken…

In many cases, the distance of china electric bike is shortened, not because of the quality of the car, but because of the "man-made" or objective conditions. For example, the unscientific operation and riding habits such as zero start, sudden braking and electrification, uphill headwind and other overloaded passengers will result in a short continuous…

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 companies to provide. Most of the electric bikes sold in the United States are high-end…

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 that electric bicycle run more time. If you have bought foldable electric bike in the…

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 and reduce the lubricity and antirust performance of the oil. Therefore, No. 30 oil or…

Chinese electric bike isn¡¯t cheap, so we need to take care of our electric bikes. Battery life termination: replace or repair battery; Battery inside the fuse break: replacement fuse; Bad contact between the battery safety tube and the seat: adjust the position of the two to make it in good contact, or replace the safety…

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 Bicycle Association has issued a certificate of origin that can only be approved by a…

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 motor can reach more than 50 kms. The battery power of the folding electric bike…

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, which is normal, and the voltage above this voltage may not turn the lamp. Low…

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 capacity value. It can be changed during the repair period. Measure the terminal voltage of…

The failure to charge is mostly due to long-time self-discharge resulting in loss of power or vulcanization. As long as the battery is in use or has been fed for a long time, will produce varying degrees of vulcanization, and hinder future service life. If the situation is not serious, you can try professional Chinese…

According to the application conditions, the parts such as front axle, rear shaft, middle shaft, flywheel, front fork, Chinese electric bike, rotating fulcrum of shock absorber should be scrubbed and lubricated every six months to a year (molybdenum disulfide grease is recommended. The driving parts in the electric wheel hub have been coated with special…
