My Golden Lion electric car was bought in September 2004 and has never been repaired.

Card selection

Brand is a symbol of quality, and the quality level of different brands is uneven. Consumers must choose brands with reliable quality, low repair rate, good after-sales service and high reputation that have been tested by authoritative departments. Consumers can pay attention to the "reputation mark" issued by China Bicycle Association on electric bicycles.

Key points of on-site procurement

1. Choose the appropriate specifications, styles and colors according to my actual needs and preferences.

2. First, choose the appearance quality of the vehicle, mainly to see whether the trademarks and decals are in good condition, and whether the surface quality of paint parts, electroplated parts, plastic parts and aluminum alloy parts is satisfactory.

3. Check the vehicle assembly quality, should:

A. all kinds of screws are fastened in place without looseness.

B handlebars, wheels, chains, cranks and pedals should be flexible to operate, and the rim should have a circumferential speed and a small amount of circumferential runout.

C handlebars, car seats, clay tablets, clothes hangers and brackets shall be installed vertically or symmetrically without obvious deviation.

D moving parts (such as chains, cranks, wheels, etc.). ) and fixing parts (such as chain cover, clay board, etc.). ) Do not rub.

4. Try the on-off key and battery lock, which are safe, reliable and easy to use. It is most convenient to use a key for electric door locks, battery locks and toolbox locks.

5. Turn on the switch, turn the speed change handle, check the stepless speed change, braking (braking) power failure and braking effect, and check whether the motor runs smoothly and the sound is normal.

6. Multi-functional and luxurious electric bicycles should also check whether the functions are in good condition.

7. Finally, invoices, chargers, certificates of conformity, instructions for use, three-guarantee cards, etc. Should be collected and properly kept.

Specification selection

Electric bicycles are generally 610 mm. At present, manufacturers design and manufacture 660mm or 560mm electric bicycles to meet the needs of consumers at different levels.

Style selection

1. There are three main driving modes for electric vehicles: one is wheel drive, the other is center drive and the other is suspension drive. The electric bicycles in the market are mainly driven by wheel hub, which is better than rear wheel drive, but the front wheel drive performance is relatively poor.

2. The position of the battery is considered from the balance of the whole vehicle and the convenience of getting on and off. It is best to put the battery in the inclined tube or vertical tube of the frame, and the configured batteries are basically economical lead-acid batteries. At present, most electric bicycles use 36V 12ah lead-acid batteries; Because the battery with 24V 12ah has a short continuous mileage, consumers have fewer choices.
