Yep. They can. Nothing special about Rad. Chinese folks designed it, and anyone over in China can copy it. They do the same with many thousands of US designed products that are patented here in the US too. Our patents are meaningless to China. That's small part of the whole trade issue Trump has been harping about. They've stolen and made billions off US IP for decades. There are many clones of other brands of ebikes coming from China. It's not just Rad that is being copied.
