CycleBar, Los Gatos

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 an 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.
