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

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

  According to incomplete statistics, more than 100 million batteries are discarded each year, and the battery life extension and maintenance device can quickly repair and regenerate the battery of Chinese electric bike. Battery life can also be extended 1-3

Although most of the current Chinese electric bike manufacturers because of the price and technology, the majority of the use of lead-acid batteries. But with many battery manufacturers speeding up research on lithium batteries and some unique advantages of lithium
