I clearly mentioned in my response that in the event that it closes down here. Har raah chalta gadha nai hota, everyone knows aliexpress is a service provider, middleman, a aggregator of storefronts and traders and keeway is a manufacturer. Tou bolna kia chah rahay ho is beyond me.
Common parts wali misaal is fine and dandy, many part numbers are interchangeable I know that, what is it that you are trying to prove?
Import par har cheez par tax parta hai, jab 2000$ ki bike li jaati hai tou uskay saath kharchay k bhi paisay hotay hee hain logoun ko paas. I am assuming that it should give some amount of work after 2 years, but not significant enough to cause need for import expensive parts. Aur agar import karna bhi parh jayay tou it can't exceed 10-20k possibly now can it considering the whole bike is chinese to begin with.
