Peloton Interactive Inc. is preparing its most significant product overhaul in several years, according to information reviewed by Bloomberg. The connected-fitness company intends to launch a refreshed version of its flagship stationary bike alongside a suite of new accessories and software that will incorporate artificial-intelligence capabilities. Management aims to use the expanded hardware lineup and AI-driven training tools to revive sales growth after a prolonged slump in demand for at-home fitness equipment. The company has not disclosed launch dates or pricing, but the push signals Peloton’s effort to regain momentum in a highly competitive market that now includes offerings from Apple, Lululemon and other technology-enabled fitness providers.
