Hi,
I am from Europe, I have done that, I imported segway analogs and also monocycles and hoverboards from China and I am reselling those in EU now.

This is my company: www.monoratas.ee
I can tell you, that finding good factory is the most important thing.

For me, it took many months and traveling in China to visit different factories, until I finally found reliable one and import.

Even I have a Chinese wife, and I know a lot about China it was still very complicated and exhausting to find a reliable factory.

What I discovered is following: In China, there are actually few real producers, most of them who are presenting them as direct producers are just trading companies, I believe about 70 % them, what are in Alibaba are trading companies.

I can help you, because I have done it and direct you to my own trusted factory or help you with other questions related, just le me know
