@gerhard23  I remembered I have learned about the brand you bought before, and the warranty of yours is only one year, and mine is two years. 

@Yolanda Ho that's not really right. It depends where you bought your bike. In the European Union we distinguish between warranty which is optional by vendor/dealer and warranty which is appointed by law. The warranty by law is 2 years in each country in the Union and it has always first priority. Regardless how long a vendor/dealer may offer his own warranty.
Feel free to post and to ask. We're glad in exchanging our experiences i.e. technical and others with your own knowledge.
You are welcome.

@gerhard23  thanks for your kind answer, I do appreciate to share what I know with you, that is a really good forum.
