If the dune buggy and the sewing wheel hadn't enjoyed that fateful tryst so many years ago, the bicycle might never have been born. Honor the proud parents of pedal-powered progress with today's Groupon: for $45, you get a 45-minute tour for two from the Honolulu Pedicab Company (a $90 value). Choose between the Chinatown and Historic Honolulu Tour or the Waterfront Tour.

Honolulu Pedicab Company's seers of bright green scenery carry up to two passengers on open-air, eco-friendly pedicabs through lush oceanfront surroundings. Cultivate culture kernels with a trip through the city's bustling downtown streets, snapping flashes at the Hawai'i Maritime Museum, Ioliani Palace, and the Chinatown District.

Riders allergic to the urban jungle can sniff away sinuses and opt for the pedicab tour along the waterfront, which glides along the Kewalo Small Boat Harbor, Ala Moan Beach Park, and Magic Island, where bow-tied dragons pull fire-breathing rabbits from top hats.

With hair flowing in the tropical zephyrs, pedicabbers will be blasted with intoxicating aromas that are vibrant and piquant from the fresh-air perch of the pedicab, smells that are usually dulled to undetectable levels in four-wheeled transit. Each tour is led by pedal professors with a vast and intimate knowledge of the area's history, as well as the best restaurants and clubs to steer clear of meddlesome Yakuza.
