I reckon there's better ways to earn a buck.
Stolen..cops here won't help you
Damaged, Broken bikes, maintenance, have you got mechanical knowledge, you probably have hire a few Thais.
You need a shop front, staff to meet and greet, book keeping etc.
I'd say your customers will be foreigners, too many dodgy, criminal types, unlicensed, drugged up.
Have you thought about a beauty salon, I've got a gf with experience......555, only joking 😂
