About Peloton


Founded in 2012, Peloton brought top talent together in its NYC headquarters to create a new concept in fitness. We loved cycling but had a hard time finding a workout that consistently fit our schedules, and our at-home workouts never felt quite up to par. So, we set out to create a world-class indoor cycling studio experience on your time, and in the comfort of your own home.


At-home fitness equipment has not evolved at the same pace as the group exercise classes that take advantage of trends in fitness, fashion and music to keep you motivated. Peloton has changed this by marrying sophisticated technology with beautiful and thoughtfully designed fitness equipment.


We are more than just a class, a cycling studio, and a bike. We deliver a fully engaging experience with the technology to make every workout effective, and the social connection to make every workout addicting.
