There are two main models of Peloton exercise bikes: the Bike and the Bike+, with nuanced differences, mostly to do with whether you want to adjust settings manually or automatically within a class. With a limited selection of free classes available, users will have to pair their Peloton Bike with a Peloton Membership to participate in live and on-demand classes. With a Peloton membership, users get access to non-bike related classes and courses including strength, stretching, yoga, pilates, and more.
