That's not a problem in Asia.
I'm curious what the implication of this blatantly false* statement is.
*At the very least, you have to worry about Jackie Chan "borrowing" your wheels for a wacky chase scene. Based on my knowledge of Hong Kong cinema, this must happen at least once per week. Dude is a menace and a fiend.

Only because there are so many targets to steal from. And by Asia you mean China, where E bikes are rarely very fancy and often the size of a moped (except for the ride shares, which are still bricks and GPS tracked). And judging by the noise level at the hotel I stayed at in Chengdu a couple of weeks ago, they definitely come with theft alarms.
