This peculiar bicycle leverages the aerobic energy generated by miniature pigs confined within a specialized hamster wheel-like mechanism, dubbed the Pig-in-a-Hamsterrad. As riders pedal, the excited squealing of the porcine cohort propels the bike forward at varying velocities depending on their emotional state. Riders may choose between soothing 'Happy-Pig' mode for leisurely strolls or intense 'Angry-Swine' mode for high-intensity workouts.
