First, the maximum speed exceeds the upper limit. The maximum speed of some electric bicycles exceeds the speed limit of 20km/h stipulated by the national mandatory standards, and most electric bicycles also hide various speed regulating devices. As a special kind of bicycle, electric bicycle runs on non-motor vehicle lanes. Speeding will pose a certain threat to the safety of other non-motor vehicles.
Second, the weight exceeds the standard. In this spot check, 60% of the total weight of electric bicycles exceeded the national limit of 40 kg. Electric bicycle is an extension product of bicycle. It is necessary to maintain the characteristics of the original bicycle and prevent the development of electric bicycle to motorcycle.
Third, the logo does not match the real thing. This spot check found that some of them are electric bicycles, but there is no flywheel and corresponding riding device, which is actually a veritable light motorcycle.
Fourth, the trampling ability can't meet the requirements. According to national standards, the 30-minute pedaling capacity of electric bicycles should not be less than 7 kilometers. However, due to the motorcycle tendency of electric bicycles, the wheel diameter is getting smaller and smaller, and the crank is getting shorter and shorter, which makes some electric bicycles fail to meet the requirements. In this spot check, 13.3% did not meet the requirements.
Fifth, some electric bicycles do not have the function of undervoltage and overcurrent protection. Undervoltage and overcurrent protection function refers to the function of preventing battery from overdischarge and overload of electrical system. If the undervoltage value is too low, the battery will be deeply discharged, which will affect the battery life. If the overcurrent value is too large, it will directly affect the reliability and working life of the motor battery, controller and system. In this spot check, 46.6% were not equipped with undervoltage and overcurrent protection devices.
Sixth, the signs are incomplete. Most electric bicycles don't have product nameplates, only trademarks, but no factory name, address, specification and model. The main reason for the above problems is that some electric bicycle manufacturers are weak in quality awareness and road traffic safety awareness. Most of the unqualified products are produced by enterprises that do not follow the mandatory national standards, and the inspection is not strict. Some small enterprises lack the overall design and quality inspection ability of products, and purchase low-grade accessories for assembly, so the product quality is poor. The quality and safety of electric bicycles are directly related to personal safety. When buying an electric bicycle, users should not only pay attention to the appearance quality of the product, but also pay attention to the reliability and safety of the product.
