The Peloton stationary bike has become one of the highlights of going to the gym for me. The design of the bike itself is stunning: the metal construction distinguishes it from the plastic casing of the other stationary bikes, giving it a luxury feel. While some stationary bikes hardly resemble traditional bikes, the Peloton is clearly modeled with a functional bike in mind. This parallelism encourages a positive appraisal from a user: the Peloton looks aerodynamic, like the bikes you would see on the street. Its sleek design and tablet interface remind me of the Tesla user experience — the tactile buttons and channel controls have been replaced with a modern glass touch screen. Once logged in, users can select from a list of live and recorded classes based on factors like time, area of focus, instructor, and music genre. The interface itself demonstrates a host of principles of persuasion and credibility that we discussed in class. For one, the fact that Peloton forces you to create an account up front means they automatically start a log of your progress, invoking the consistency tactic we talked about: if you start seeing your progress, you feel compelled to continue your identity as a rider to maintain that image. In addition, when you take a recorded class, you can see the sheer number of people who have also participated in that class: social proof at work. I can appreciate Peloton both for creating a great experience and for so cleverly integrating principles of persuasive design. They’ve definitely gotten me hooked.
