Honolulu Holo Cycling Studio
Green hills and blue tidal waves rise from the mural that colors Honolulu Holo Cycling Studio, where cyclists ascend invisible slopes and sprint across imaginary beaches on Spinner Blade bikes. Instead of melting calories outside amid the island’s scorching sun rays, the studio’s patrons breeze through a refreshing, air-conditioned space lined with wall-length mirrors and shiny wooden floors. Seasoned teachers lead this fitness adventure, alerting riders when obstacles such as trees and Jupiter appear on the horizon. Music and videos fuel each revolution of the wheels, filling calves with energy during challenging climbs. To accommodate riders of different sizes, the bikes can be adjusted to fit long or short legs and arms.
