Shipping will eat labor savings alive for these. Their frames are rigid so you'd have to either ship them in huge boxes the slow way (terrible for a custom product like this [0]), air freight them (probably upwards of 300 dollars for the size? That's just a wild guess though) or ship them disassembled and take the durability hit that would require. If they were less customized to fit the user you could but it's not the product we're looking at so you can't make them in mass quantity and ship them to a warehouse in the US like you can with a lot of less custom products.
It's also far less like bikes than you're thinking. They have 5 major adjustments for a total of about 25k different configurations. And those don't seem to be majorly exclusive to each other either.
