When Mr. Biden was cloistered during the coronavirus surge this spring, The New York Times reported that he began each day “with a workout in an upstairs gym that contains a Peloton bike, weights and a treadmill.” The Biden team did not respond to requests for comment, but a person close to the president-elect said that Mr. Biden and his wife, Jill Biden, engage in regular morning negotiations over who gets to ride first.

But the Peloton tablets have built-in cameras and microphones that allow users to see and hear one another if they choose, and for Mr. Biden, therein lies the rub. The last thing the C.I.A. wants is the Russians and the Chinese peering or listening into the White House gymnasium. Last week, Popular Mechanics warned about the security risk under the headline “Why Joe Biden Can’t Bring His Peloton to the White House.”

The article prompted an explosion of chatter in Peloton world, but really, cybersecurity experts say, if Mr. Biden wants his bike, he can surely have it, though it might bear little resemblance to the off-the-assembly-line version after the Secret Service and the National Security Agency are finished with it.
