The top three most efficient modes of human-powered transportation are (in no particular order): Flintstone cars, bicycles, and a palanquin carried by the various monarchs you've conquered and overthrown. Hop on the most feasible of these choice conveyances with today's Groupon: for $12, you get a four-hour bike rental (up to a $24 value) from Ventura Bike Depot, located at the link-up between the Ventura Beach and Ojai bike paths.

Open seven days a week, Ventura Bike Depot is a full service bike shop, renting the majority of their inventory to suit the peddling aspirations of their wheel-less clientele. Today's Groupon allows customers choose any one of the hybrid, beach cruiser, front suspension mountain, and kids bikes from the fleet of man-powered velocipedes valued at $24 or less. If desired or required, customers are welcome to upgrade to a tandems, quadricycles, or other premium peddle-powerhouses for an additional fee. Regardless of how you ride, Ventura Bike Depot will throw in all necessary helmets, locks, seat belts, and leg bands. Likewise, the staffers will happily fill water bottles with mineral-rich Kangen water for free, saving thirsty travelers from the woes of waiting for rain or preying for proximate killer whale shows.
