Shopping common sense
- Choose a brand. Pay attention to choosing well-known brands, quality and after-sale service are guaranteed.
- Pick a car model. The safety and performance of different models vary greatly. It is recommended to choose a simple and portable type.
- Look at the appearance. Pay attention to the surface smoothness and gloss, and pay attention to the quality of welding, painting and electroplating.
- Find feelings. Carry out a trial ride, feel whether the vehicle is starting, accelerating, and driving smoothly, whether the vehicle is comfortable to handle, and check the brake tightness, handlebar flexibility, and wheel mobility.
- Check the procedures. Check whether the production license, instruction manual, and qualification certificate are valid and complete, and check whether the accessories provided with the vehicle are complete. Pay special attention to whether it is a locally approved vehicle.
- Look at the configuration. Whether related important components, such as batteries, motors, chargers, controllers, tires, brake levers, etc., are branded products. The motor is best to choose brushless.
Vehicle maintenance
Pay attention to cleaning first. After encountering water, especially salt water in winter (many cities spray salt water after heavy snow in winter to avoid freezing), clean it in time, otherwise it will easily cause metal parts to rust and paint film aging and fall off. The second is to pay attention to the maximum adjustment height. After the new car has been riding for a period of time, the whole car should be inspected and adjusted according to the requirements of the manual. At this time, tightening and lubrication are essential. Check whether the fasteners are loose and whether the transmission parts are flexible. Pay attention to wipe off the slick oil after lubricating the chain, and just apply a little oil on the flywheel. The tires should be properly inflated, otherwise it will affect the comfort and service life of riding. The brakes are the basic guarantee for safety, and they should be checked at any time. Any problems should be adjusted or repaired immediately.
