Mana, I finally found your Ebay site.
Wow, thats a really affordable price. $450.00 for bike and $250.00 for shipping.
Suggestion for you when you ship make sure you list it as a bicycle, not motorized bicycle.
This way when listed as a bicycle the purchaser will not have problems with customs. Here in USA motors are available for the bicycle.
Can you also list on your ebay site bicycle parts that are sold separately, Frame, Gas Tank, Wheels, Forks, Seat Pan, Pedal Crank, Handlebars, this will help your customers who cannot afford a complete bicycle, and they could purchase the parts separately when they have more money and build your bicycle as they can buy parts this to build your bicycle.
Peace C.H.
