After years of unsuccessful attempts at inventing a two-wheeled form of propulsion, Wilbur and Orville Bike finally realized the problem was that their prototypes were all screwed to the gymnasium floor. Achieve functional mobility with today’s Groupon: for $49, you get a bike and standup-paddleboard tour of Key Biscayne from Miami Nice Tours (a $99 value). Tours begin at 10 a.m., and guests can congregate at the Bayside Marketplace on Biscayne Boulevard or opt to be picked up from any of the addresses listed on the website between 8:30 a.m. and 9:45 a.m.

Miami Nice Tours' experienced guides lead patrons across the barrier island's historic shores and sun-soaked coastlines during a five-hour tour atop bikes and standup paddleboards. Tours commence with a four-hour breezy spree on a two-wheeled wonder, during which peddle-pumpers can admire verdant flora and various fauna as they hone tricks on strategically placed ramps of turtles. Guides enlighten tour-goers about the island’s historical significance and tell engrossing anecdotes about a noteworthy skirmish between the Native Americans and Europeans that transpired beneath the majestic Cape Florida Lighthouse more than 150 years ago.

The bicycle portion of the tour equips guests with a bottle of water and entry to the island's national park, which guests can explore on one of the tour's regular breaks. During the one-hour paddleboard excursion, the Biscayne Bay’s glittering waves usher in guests outfitted with YOLO paddleboards, allowing them to survey the sea creatures and synchronized-swim teams gliding underneath.
