The insanely successful Peloton bikes, which changed the fitness game, have done so by jacking songs to use for its instructional classes ... according to a new lawsuit.
Peloton is being sued by several different music publishing companies because -- according to new docs obtained by TMZ -- the company did not acquire the rights to play numerous hit songs featured in its wildly popular interactive spin classes.
The docs say Peloton currently has more than 600k subscribers and is reported to be worth more than $4 BILLION ... and the music publishing companies claim a big part of that success is due to the music playing during the classes.
Some of the songs listed in the suit include "Umbrella" and "Diamonds" by Rihanna, "Don't Wake Me Up" by Chris Brown, along with older hits like "Hit Me With Your Best Shot" by Pat Benatar. Rihanna's hit track, "Umbrella," has been used in at least 55 workout vids since 2017 ... according to the docs.
All in all, the publishers say they've ID'd more than a thousand songs in their catalogs that Peloton is using without proper permission.
Peloton is being sued for massive damages ... up to $150 million.
