Bicycles, like cars, are generally not fake. If you are really worried, go to a store and buy them. At least there is some guarantee.

The identification method of genuine and fake giant bicycles is as follows:

1 Each giant bicycle has a unique 15-digit frame number (located below Wutong)

2 The authenticity of the corresponding frame number can be inquired through the company's free service hotline

3 The common phenomenon of counterfeit giant bicycles is that there are no 15-digit frame numbers or the frame numbers have been maliciously destroyed

4 Wutong has a 15-digit frame number stamped with steel.

5 as long as banana oil is refurbished, the painted goods can be wiped off with banana oil. You don't need to bring them when you buy a car. Let the merchants use banana oil to show you. If the paint is wiped off, it will be a refurbished fake giant. If you are afraid that the merchants are not using banana oil, just ask the smell. Banana oil has a pungent smell, just like nail polish remover.

The sign under the faucet: A. Fake: flat (that is, flat to the touch). This kind of giant is most likely to be fake. Many merchants tell you that this is the old giant, but it is not easy to buy the old giant now. Most of them are the second one I mentioned.

I hope my answer can help you.
