At present, there are many brands of electric bicycles. Consumers should choose brands with long operating hours, low repair rates, good quality, and reputable brands. For example, choose companies that have passed the ISO9001-2000 quality management system certification. The strength requirements and performance requirements of electric bicycle components should be higher than bicycles. When purchasing, the user should look at the quality of the selected parts of the vehicle, such as: whether the welding and surface of the frame and the front fork are defective, whether the manufacture of all parts is good, whether the double supports are strong, whether the tires use famous brands and fasteners Whether it is rust-proof, etc. A set of new batteries with a capacity of 36V/12Ah will generally have a continuous mileage of about 50 kilometers. Under normal circumstances, the longest riding distance per day is about 35 kilometers. It is appropriate (due to road conditions that affect the actual continuous mileage). If the longest distance is more than 50 kilometers, it is necessary to consider whether there is the possibility of charging at intervals twice a day. If there is no such possibility, it is not suitable to buy an electric bicycle. Electric bicycles can generally be divided into four types: luxury type, ordinary type, front and rear shock absorber type, and portable type. The luxurious type has complete functions, but the price is high, the ordinary type has a simple structure, economical and practical; the light type is light and flexible, but the stroke is short. Consumers should pay attention to this when purchasing. As the current electric bicycle components are not yet universal, and the maintenance cannot be socialized, you must pay attention to whether there is a dedicated maintenance service department in the area when purchasing an electric bicycle. If the price is cheap and the after-sales service is ignored, it is easy to be fooled.
