People who don’t have their own bicycles often try to make them by sawing their cars in half or affixing extra wheels to their unicycles. Borrow a traditionally made bicycle with today’s Groupon: for $12, you get an eight-hour bike rental at Big Shell Bikes in Port Aransas (a $24 value). Though reservations are not required, Big Shell Bikes suggests that clients call ahead to ensure bike availability. The shop is located in the same space as Bam Bam Artwares and is closed on Tuesdays.

Big Shell Bikes bestows coastal riders with maintained bicycles for self-propelled adventures through the scenic area. Riders can climb atop cruiser-style bikes such as women’s medium Huntington Beach bike or men’s large Electra Cruisers to propel themselves around Port Aransas’ awe-inducing views of sandy shores, rolling waves, and heavily guarded sand castles. Big Shell maintains its fleet of pedal-powered transports with only industry-known cruiser-brand parts, such as Schwinn and Huffy, to ensure smooth, solid rides. Additionally, Grouponers can opt to apply their vouchers toward the rental of a sand bike ($53 a day), an eight-speed steed equipped with thick tires designed to glide through sandy shores without bogging down or accumulating itchy grains between bike crevices.
