i have just put my order in for mine, the process was better than ok, it was a case of emailing them, then you set an account on Alibaba and then message chat through that, you can alter what you want on the bike and then they set the order up, i paid half of the money up front and the rest will be paid when the bike is ready, they will send pictures of the bike to make sure your happy, you pay then they ship, shipping only at the minute due to COVID.
the price for shipping was $550 the bike will take up to 3 months to make and a month to ship. they are 7 hours in front of me as i live in the UK
