Peloton, a spinning studio in Chelsea, has become a cult favorite, thanks to its energetic teachers, smooth-riding bikes, coffee and juice bar and luxurious shower products. But Peloton’s most ingenious development is its bikes for purchase, which come equipped with a state-of-the-art monitor that allows home spinners unlimited streaming. Every class offered at the studio is available to live-stream at home, and the studio’s on-demand library includes more than 400 classes and is constantly expanding.
