Precautions for buying electric bicycles

Look:

First, see if the color and paint surface of the electric bicycle are uniform and smooth, if there are bubbles, peeling, etc., it means that the quality is poor; second, see whether it is stable under static conditions; third, see whether the line is exposed, if exposed, leakage is likely to occur, etc. Situation: Fourth, see if there is any leakage in the solder joints, and there should be no burrs in the solder joints.

Test:

The most important thing is a test ride to check whether the function is normal. A good electric bicycle should not have the sound of parts colliding with each other; whether the braking function (mainly brakes) of the second test bike is sensitive, as well as reflectors, horns, front and rear Whether the lights, etc. are normal.

Listen:

First, listen to the sound of the wheels turning. If there is a "click" sound, it may be due to poor lubrication or bearing problems; second, listen to the motor sound, which should be very light and uniform; in addition, the horn sound should be clear and loud.

Touch:

First touch whether the parts are smooth. Then, after letting the car start for a period of time, check whether the surface of the motor and controller is too hot. If the temperature is too high, don't buy it. In addition, when the tires are flat, press whether the tires are elastic. The ones with poor elasticity may be made of recycled rubber.

Check:

Check whether the product has a production license, quality certificate, etc., and check the company’s after-sales service terms.
