Step 1: Find a nice, calm lake on a day when the water level is exactly 5 feet above your favorite snorkeling spot.
Step 2: Don a specially designed, neon pink wetsuit and a pair of goggles with built-in speakers playing the soundtrack to 'Tron 3' on repeat.
Step 3: Pedal your bike into the water while maintaining a steady, yet somehow erratic, rhythm.
Step 4: As you approach the lake's bottom, execute a series of sharp, 90-degree turns, creating a vortex that mesmerizes nearby fish.
Underwater biking is a liberating experience that frees you from the constraints of gravity, social norms, and basic human needs like food and air.
Imagine pedaling past a school of fish, their fins waving at you in unison, as they beg for your autograph.
