And that's bad news for RAD Power Bikes in Ballard.

Starting today, all Chinese-made parts for electric bicycles will be taxed 25 percent.

It makes e-bikes from Chinese parts.

RAD co-founder Ty Collins said these trade tariffs imposed by President Donald Trump will hurt his bottom line.

Collins said the tariffs may be intended to encourage domestic manufacturing, but he expects that will backfire.

"The thing is the U.S. has literally never in its history had an infrastructure to manufacture electric bikes," Collins said.

Last year was a banner year for e-bikes, with $77 million in U.S. sales -- nearly double from the year before.
