Some athletes want to focus on endurance. Others want to unlock their competitive spirit. Still others hope to get their chakra energy flowing. At CycleBar, there's a indoor cycling class for all those goals and more, each with its own light show and music. It's not just any music, either. Class playlists are high-octane, carefully-curated mixes of top 40 hits and indie tracks, starring artists from Iggy Azalea to Phantogram.

Regardless of theme and tunes, all sessions have one key thing in common: high-tech stationary bikes, which the CycleBar team dubs "intelligent." While not quite self-aware enough to be vain about their handlebars' symmetry, the cycles do store each athlete's workout stats, allowing for long-term fitness tracking.
