Sort, with help, the better China direct sources. No reason to pay a reseller for a product purchased direct. Your Island country may be kinder on duty charges from China. And of course currency exchange can play a part. With a trusted seller moneys can be safely reasonably done by an international bank exchange. More options...
Do you have a local bike shop, or good bike repair spot?
Having lived on an island where everything was inflated, and having used more than a dozen motors and kits, I’d opt for a well supported brand of motor, controller, and display. A bike with common enough parts that even a slow boat to the island would still at least be available.
Which countries is your island nation most amenable with?
PS. Insanely jealous that I couldn’t retire to any number of islands!
Mr. Jaszewski, I am neither retired. Nor, am I new to this island country. It is my homeland.
And, I know of no other. Of course, I hope you someday get your wish to retire. However, I am not retired. Nor, a casual visitor to our island.
In fact, I can assure you that there is no place like your own home land. And, for where I live there is no better place for me to live.
Indeed, where you live is just like where I live, it's just not the same geography. Our problems and issues are just like those of your own. No different. In fact, our lifestyle is probably very similar. I get up and work the same as yourself. And, without all of the conveniences you take for granted.
Thus, be happy that you are probably surrounded by family and lifelong friends and on an equal basis as I have no doubt that we live quite similar lives...just like everyone else on this board, without the need to provide our address, our telephone number nor our shoe and hat size.
Bless'
